Biography of Mary, Queen of Scots

Biography of Mary, Queen of Scots Mary, Queen of Scots (December 8, 1542–February 8, 1587), was the ruler of Scotland as well as a potential claimant to the throne of England. Her tragic life included two disastrous marriages, imprisonment, and eventual execution by her cousin, Queen Elizabeth I of England. Fast Facts: Mary, Queen of Scots Known For: Queen of Scotland and cousin to Queen Elizabeth I who eventually had Mary executedAlso Known As: Mary Stuart or Mary StewartBorn: December 8, 1542 in Linlithgow Palace, ScotlandParents: King James V and his French second wife, Mary of GuiseDied: February 8, 1587 in Fotheringhay Castle, EnglandEducation: Extensive private education including instruction in Latin, Greek, poetry and prose, horsemanship, needlework falconry, Spanish, Greek, and FrenchSpouse(s): Francis II, Dauphin of France, Henry Stuart, Lord Darnley, James Hepburn, 1st Duke of Orkney and 4th Earl of BothwellChildren: James VI of England (also James I of Scotland)Notable Quote: Marys last words are recorded as: â€Å"In manus tuas, Domine, commendo spiritum meum† (â€Å"Into thy hands, O Lord, I commend my spirit†) Early Life The mother of Mary, Queen of Scots, was Mary of Guise (Mary of Lorraine) and her father was James V of Scotland, each in their second marriage. Mary was born on December 8, 1542, and her father James died on December 14, so the infant Mary became queen of Scotland when she was just a week old. James Hamilton, Duke of Arran, was made regent for Mary, Queen of Scots, and he arranged a betrothal with Prince Edward, the son of Henry VIII of England. But Marys mother, Mary of Guise, was in favor of an alliance with France instead of England, and she worked to overturn this betrothal and instead arranged for Mary to be promised in marriage to Frances dauphin, Francis. The young Mary, Queen of Scots, only 5 years old, was sent to France in 1548 to be raised as the future queen of France. She married Francis in 1558, and in July 1559, when his father Henry II died, Francis II became king and Mary became queen consort of France. Marys Claim to the English Throne Mary, Queen of Scots, also known as Mary Stuart (she took the French spelling rather than the Scottish Stewart), was the granddaughter of Margaret Tudor; Margaret was the older sister of Henry VIII of England. In the view of many Catholics, the divorce of Henry VIII from his first wife, Catherine of Aragon, and his marriage to Anne Boleyn were invalid, and the daughter of Henry VIII and Anne Boleyn, Elizabeth, was therefore illegitimate. Mary, Queen of Scots, in their eyes, was the rightful heir of Mary I of England, Henry VIIIs daughter by his first wife. When Mary I died in 1558, Mary, Queen of Scots, and her husband Francis asserted their right to the English crown, but the English recognized Elizabeth as the heir. Elizabeth, a Protestant, supported the Protestant Reformation in Scotland as well as in England. Mary Stuarts time as queen of France was very short. When Francis died, his mother Catherine de Medici assumed the role of regent for his brother, Charles IX. Marys mothers family, the Guise relatives, had lost their power and influence, and so Mary Stuart returned to Scotland, where she could rule in her own right as queen. Mary in Scotland In 1560, Marys mother died, in the middle of a civil war she stirred up by attempting to suppress the Protestants, including John Knox. After the death of Mary of Guise, the Catholic and Protestant nobles of Scotland signed a treaty recognizing Elizabeths right to rule in England. But Mary Stuart, returning to Scotland, managed to avoid signing or endorsing either the treaty or recognition of her cousin Elizabeth. Mary, Queen of Scots, was herself a Catholic and insisted on her freedom to practice her religion. But she did not interfere with Protestantisms role in Scottish life. John Knox, a powerful Presbyterian during Marys rule, nevertheless denounced her power and influence. Marriage to Darnley Mary, Queen of Scots, held on to hopes of claiming the English throne which she considered hers by right. She turned down Elizabeths suggestion that she marry Lord Robert Dudley, Elizabeths favorite, and be recognized as Elizabeths heir. Instead, in 1565 she married her first cousin, Lord Darnley, in a Roman Catholic ceremony. Darnley, another grandson of Margaret Tudor and heir of another family with a claim to the Scottish throne, was in the Catholic perspective the next in line to Elizabeths throne after Mary Stuart herself. Many believed that Marys match with Darnley was impetuous and unwise. Lord James Stuart, the Earl of Moray, who was Marys half-brother (his mother was King James mistress), opposed Marys marriage to Darnley. Mary personally led troops in the chase-about raid, chasing Moray and his supporters to England, outlawing them and seizing their estates. Mary vs. Darnley While Mary, Queen of Scots, was at first charmed by Darnley, their relationship soon became strained. Already pregnant by Darnley, Mary, Queen of Scots, began to place trust and friendship in her Italian secretary, David Rizzio, who in turn treated Darnley and the other Scottish nobles with contempt. On March 9, 1566, Darnley and the nobles murdered Rizzio, planning that Darnley would put Mary Stuart in prison and rule in her place. But Mary outwitted the plotters: she convinced Darnley of her commitment to him, and together they escaped. James Hepburn, Earl of Bothwell, who had supported her mother in her battles with the Scottish nobles, provided 2,000 soldiers, and Mary took Edinburgh from the rebels. Darnley tried to deny his role in the rebellion, but the others produced a paper that he had signed promising to restore Moray and his fellow exiles to their lands when the murder was complete. Three months after Rizzios murder, James, the son of Darnley and Mary Stuart, was born. Mary pardoned the exiles and allowed them to return to Scotland. Darnley, motivated by Marys split from him and by his expectations that the exiled nobles would hold his denial against him, threatened to create a scandal and leave Scotland. Mary, Queen of Scots, was apparently by this time in love with Bothwell. The Death of Darnley- and Another Marriage Mary Stuart explored ways to escape from her marriage. Bothwell and the nobles assured her that they would find a way for her to do so. Months later, on February 10, 1567, Darnley was staying at a house in Edinburgh, possibly recovering from smallpox. He awakened to an explosion and fire. The bodies of Darnley and his page were found in the garden of the house, strangled. The public blamed Bothwell for the death of Darnley. Bothwell faced charges at a private trial where no witnesses were called. He told others that Mary had agreed to marry him, and he got the other nobles to sign a paper asking her to do so. Immediate marriage, however, would violate any number of etiquette and legal rules. Bothwell was already married, and Mary would be expected to formally mourn her late husband Darnley for a few months at least. Before the official period of mourning was complete, Bothwell kidnapped Mary; many suspected that the event occurred with her cooperation. His wife divorced him for infidelity. Mary Stuart announced that, despite her kidnapping, she trusted Bothwells loyalty and would agree with the nobles who urged her to marry him. Under threat of being hanged, a minister published the banns, and Bothwell and Mary were married on Mary 15, 1567. Mary, Queen of Scots, subsequently attempted to give Bothwell more authority, but this was met with outrage. Letters (whose authenticity is questioned by some historians) were found tying Mary and Bothwell to Darnleys murder. Fleeing to England Mary abdicated the throne of Scotland, making her year-old son James VI, King of Scotland. Moray was appointed regent. Mary Stuart later repudiated the abdication and attempted to regain her power by force, but in May 1568, her forces were defeated. She was forced to flee to England, where she asked her cousin Elizabeth for vindication. Elizabeth deftly dealt with the charges against Mary and Moray: she found Mary not guilty of murder and Moray not guilty of treason. She recognized Morays regency, and she did not allow Mary Stuart to leave England. For nearly 20 years, Mary, Queen of Scots, remained in England, plotting to free herself, to assassinate Elizabeth, and to gain the crown with the help of an invading Spanish army. Three separate conspiracies were launched, discovered, and squelched. Death In 1586, Mary, Queen of Scots, was brought to trial on charges of treason in Fotheringay castle. She was found guilty and, three months later, Elizabeth signed the death warrant. Mary, Queen of Scots, was executed by beheading on February 8, 1587. Legacy The story of Mary, Queen of Scots, is still well known more than 400 years after her death. But while her life story is fascinating, her most significant legacy resulted from the birth of her son, James VI. James made it possible for the Stuart line to continue, and for Scotland, Ireland, and England to unite through the Union of the Crowns in 1603. Famous Quotes The best-known quotations from Mary, Queen of Scots, relate to her trial and execution. To those who stood in judgment of her relative to accusations of plotting against Elizabeth: Look to your consciences and remember that the theatre of the whole world is wider than the kingdom of England.To those executing her: I forgive you with all my heart, for now, I hope, you shall make an end of all my troubles.Last words, prior to beheading: In manus tuas, Domine, commendo spiritum meum (Into thy hands, O Lord, I commend my spirit).

The Efficacy And Advantages Of Inserting Foreign Genes Into The Essay

The Efficacy And Advantages Of Inserting Foreign Genes Into The Chloroplastic Genome Instead Of The Nuclear Genome - Essay Example Another batch of DNA was treated in a likewise manner, except that nucleotides containing thymine were added instead of adenine. (Avril, 187-94) When these two samples of DNA were mixed, the complementary "tails" of A- and T-bearing nucleotides became joined by hydrogen bonding. This combined the once separate fragments into long, interconnected chains. DNA ligase was then added to form bonds between the sugar and phosphate groups. The two DNA strands were now one. It was certainly intriguing that one could now cut up DNA into unpredictable heterogeneous fragments and randomly stitch them back together. However, for further insights into the organization of DNA and its genes -- that is, the determination of precise nucleotide sequencesvery specific nucleases would have to be found. The prevailing opinion was that such specific DNA-cutting capability did not exist in nature. The only clue to the possibility that more specific nucleases might exist came from observations beginning as early as 1953 that when DNA molecules from E. coli were introduced into another slightly different form of E. coli they seldom functioned genetically. They were quickly broken down into smaller fragments. This apparently was part of a system that had evolved in bacteria to protect them against the entrance of foreign DNA. In addition to all of the other more obvious forms of competition in nature, there is a constant invisible struggle played out in the microscopic world, in this case between bacteria and bacteriophages. Darwin's natural selection is recreated here on a minute scale. (David, 131-44) First, bacteria can be grown under controlled conditions, rapidly and in enormous numbers. Overnight, a few cells will multiply into literally billions. It is very important to understand that a bacterial cell ordinarily reproduces simply by copying itself. Assuming that no mutations occur in the cells, all the descendants of that one cell are identical. Such a population of cells originating from a single cell is termed a "clone" and the process of producing that clone is referred to as "cloning" the cell. The DNA in a typical bacterial cell exists in two forms. One is the single bacterial chromosome which, unlike the chromosomes in our cells, is in the form of a circular molecule. The DNA of all other organisms can be likened to a long string. In bacteria, the ends of the string are joined, forming a circle. In addition to the DNA in the bacterial chromosome, DNA also occurs in bacteria in the form of plasmids. These, like the bacterial chromosome, are also circular DNA molecules, but much smaller. When the bacterial cell divides, the bacterial chromosome replicates and one chromosome is passed on to the new cell. Likewise, each of the plasmids replicate and half are delivered to the next generation. The plasmids are unique, independent, self-replicating DNA molecules which can exist only within the living bacterial cell. Plasmids can easily be isolated from bacteria by breaking open the cells with enzymes which break down the cell wall. The resulting mix is centrifuged.The heavier chromosomal DNA, termed "genomic" DNA, as well as cell fragments will go to the

Project Management - planning, conduct, administering, and closing Essay

Project Management - planning, conduct, administering, and closing supply chains [sap5] - Essay Example There are companies that successfully manage internal aspects of their supply chain plan. However, external issues create a greater problem, specifically for  small businesses (Kouvelis, Chambers and Wang, 2006). Small firms have smaller network of  suppliers by building relationships and increasing efficiency hence lowering risk. Ordinarily, certain industries experience higher  supply chain  risks. For instance, pharmaceutical and food companies have strong foundation and understanding of strategy for safeguarding against supply chain problems and interruptions. Effective strategies on supply chain management improve aspects of business like operations and customer service. Code of Conduct Responsibility for people and the environment affects supply chain operations. The role of supply chain includes verifying compliance, making demands, and creating long-term relationships with suppliers (Tyndall, 2004). Moreover, it has to support efforts for sustainable improvements. Cod e of Conduct forms the fundamentals of efforts for improving work environment and working conditions for manufactured products. The code comprises demands pertaining environmental impacts and human rights targeting operations, suppliers and manufacturers. The Code of conduct requirements are derived from the Rights of the Child and the UN Declaration on Human Rights. All manufacturers and suppliers should ratify the Code of Conduct so as to be part of the supply chain. The responsibility of Suppliers is in ensuring that their own manufacturers and suppliers adhere to the Code (Kouvelis, Chambers and Wang, 2006). Manufacturers and Suppliers who cannot or will not sign the Code or live up to organizational needs may not be allowed business. The Code requirements include prohibition of child or forced labour, non discrimination based on personal characteristics or beliefs. Workplace health and safety should be prioritized alongside safe and correct handling of waste and hazardous subst ances. Ultimately, the working conditions must be acceptable. Administering Supply Chain Administering supply chain requires performance of cost-to-serve analysis and regular demand. Fundamentals of segmentation are based on profitability of customers, products and demand dynamics. This analysis gives the required information meant to tailor supply chain policies and service concessions meant to raise the overall profitability of the portfolio. The change in the dynamics of demand and profitability in today's quickly changing business landscape has institutionalized a standard cadence. In the recent past, demand has been regarded as a single requirement to reactions of supply chain. Today, demand signals emanates from forecasts, orders, and safety stock coming from different channels such as Web, retail, enterprise and distributors (Kouvelis, Chambers and Wang, 2006). Furthermore, demand signals originate from different customer types where large, highly profitably customers are com pared to small, unprofitable customers. Besides, diverse customers have different fulfilling relationships depending on the service needed, the customer volume and profitability, and customer support channels. One of the problems facing supply chain managers is the dynamics of supply chain cost structures. There is a greater fluctuation on fuel costs, labor costs, and currency exchange rates for low-cost countries. Profitable sourcing strategies will change to

Connection in Forster’s Howards End Essay -- Howards End Essays

  Ã‚  Ã‚   The epigraph of E.M. Forster's novel Howards End is just two words: "only connect".   As economical as this gesture seems, critics and interpreters have made much of this succinct epigraph and the theme of connection in Howards End.   Stephen Land, for example, cites a: demand for connection, in the sense of moving freely between the two Forsterian worlds - the two "sides of the hedge", the everyday world of social norms and the arcadian or paradisal world of individual self-realization - has its roots in earlier stories..." [1]  Ã‚   He goes on to say that "each [character] must reconcile or connect for himself the range of conceptual polarities exposed by the story - prose and passion, seen and unseen, masculine and feminine, new and old"   (Land, 165).   Land reads the novel as some sort of compromise between these two worlds - the realm of social justice and the realm of the individual.   Other critics have made similar gestures.   James McConkey, for one, feels that "Margaret will reconcile the human and transcendent realms so that she may live in harmony with the human; the voice senses the connection through its remove from both." [2]  Ã‚   These critics seem to confuse "connection" with "reconciliation", seem to read the novel as a triumph for humanism and social justice.   I feel this is a little bit of . . . fudging.   True, the characters in Howards End experience reconciliation at the close of the novel - but reconciliation occurs only when love passes out of the novel, when the narrative ceases to be a bridge between two worlds.   The meaning of the word "connect" diminishes as the novel progresses, gradually loses its mythic, transcendent meaning.    The "only connect" moment referenced in the epigraph comes wh... ...any remnant of the bridge between the paradisal world and the world of manners and civic duty.   The concept of connection is so degraded as to be unrecognizable.   This is what happens after love fails. The celestial omnibus will not stop at Howards End again.             [1] Stephen Land.   Challenge and Conventionality in the Fiction of E.M.

Business Continuity Planning

Though interruptions to business can be due to major natural disasters such as fires, floods, earthquakes and storms; or due to man-made disasters such as wars, terrorist attacks and riots; it is usually the more mundane and less sensational disasters such as power failure, equipment failure, theft and sabotage that are the causes behind disruptions to business.A Business Continuity Plan or â€Å"Continuity of Business Planning (CoB Plan) †¦ defines the process of identification of the applications, customers (internal & external) and locations that a business plans to keep functioning in the occurrence of such disruptive events, as well the failover processes & the length of time for such support. This encompasses hardware, software, facilities, personnel, communication links and applications† (MphasiS, 2003).A Business Continuity Plan is formulated in order to enable the organization to recover from a disaster with the minimum loss of time and business by restoring its critical operations quickly and smoothly. The Business Continuity Plan should be devised in such a way that it involves not only the recovery, resumption and maintenance of only the technology components but also of the entire business. Recovery of only the ICT systems and infrastructure may not always imply the full restoration of business operations.The Business Recovery Planning at XE therefore envisages the consideration of all risks to business operations that may include not only ICT applications and infrastructure but also directly impact on other business processes. After conducting an extensive Business Impact Analysis (BIA), Risk Assessment for XE was carried out by evaluating the assumptions made in BIA under various threat scenarios. Threats were analyzed on the basis of their potential impact to the organization, its customers and the financial market it is associated with.The threats were then prioritized depending on their severity. The following threats were identifi ed for XE: 1. Natural disasters such as floods, fires, storms, earthquakes, extreme weather, etc. 2. Man-made disasters such as terrorist attacks, wars and riots. 3. Routine threats that include: a. Non-availability of critical personnel b. Inaccessibility of critical buildings, facilities or geographic regions c. Malfunctioning of equipment or hardware d. Inaccessibility or corruption of software and data due to various reasons including virus attacks e. Non-availability of support servicesf. Failure of communication links and other essential utilities such as power g. Inability to meet financial liquidity requirements, and h. Unavailability of essential records. Organizing the BCP Team The first and most important step in developing a successful disaster recovery plan is to create management awareness. The top-level management will allocate necessary resources and time required from various areas of the organizations only if they understand, realize and support the value of disast er recovery. The management has to also accord approval for final implementation of the plan.The BCP team therefore has to have a member from the management who can not only provide the inputs from the management but also apprise the management and get its feedback. Besides these, each core or priority area has to be represented by at least one member. Finally, there has to an overall Business Continuity Plan coordinator who is responsible not only for co-ordination but also for all other aspects of BCP implementation such as training, updating, creating awareness, testing, etc. The coordinator usually has his or her own support team.XE’s Business Continuity Planning team would therefore comprise representatives from the management and each of the core or priority areas, and would be held together by the BCP coordinator. Even in the case of outsourcing of the BCP, it is necessary for the management and nominated members from the core or priority areas to be closely associated with each step of the planning process. Crucial Decisions The key decisions to be made in formulating the Business Continuity Plan for XE were associated with the individual steps that were undertaking in making the BCP.The first step of Business Impact Analysis (BIA) involved making a work flow analysis to assess and prioritize all business functions and processes including their interdependencies. At this stage, the potential impact of business disruptions was identified along with all the legal and regulatory requirements for XE’s business functions and processes. Based on these, decisions on allowable downtime and acceptable level of losses were taken. Estimations were made on Recovery Time Objectives (RTOs), Recovery Point Objectives (RPOs) and recovery of the critical path.The second step of Business Continuity Planning comprised of risk assessment during which business processes and the assumptions made in the course of BIA were evaluated using various threat scenario s. The decisions made at this stage included the threat scenarios that were to be adopted, the severity of the threats and finally identification the risks that were to be considered in the BCP based on the assessments made. The next step of Risk Management involved drawing up of the plan of action with respect to the various risks.This was the stage at which the actual Business Continuity Plan was drawn up, formulated and documented. Crucial decisions such as what specific steps whould be taken during a disruption, the training programs that should be organized to train personnel in implementation of the BCP, and the frequency of updating and revisions that would be required were taken at this stage. Finally, in the Risk Monitoring and Testing stage, decisions regarding the suitability and effectiveness of the BCP were taken with reference to the initial objectives of the Business Continuity Plan. Business Rules and System Back-upsMy friend works for the Motor Vehicles department t hat issues driving licenses for private and commercial vehicles. Applicants for any license initially come and deposit a fee. The particulars of the specific applicant along with photograph and biometrics in the form of finger prints are then entered into the database. Thereafter, the applicant undergoes a medical test, the results of which are again entered into the database of the system. If approved in the medical test, the applicant has to appear for an initial theoretical test on driving signs and rules and regulations.If the applicant passes the test, he or she is given a Learner’s License. The applicant then comes back for the practical driving test after a month, and is awarded the driving license if he or she is able to pass the test. New additions are made to the database of the driving license system at every stage of this workflow. Though the tests for the learner’s license and driving license are held three days in a week, an individual can apply any day o f the five working days of the department. People also come for renewal of driving licenses.Driving licenses are usually issued for a period of one to five years depending on the age and physical condition of the applicant. In the case of commercial vehicles, an applicant first has to obtain a trainee driving license and work as an apprentice driver for two years before he or she becomes eligible for a driving license to drive a commercial vehicle. Moreover, a commercial driving license is issued only for a year at time, and the driver has to come back for evaluation and medical tests every year.The number and frequency of transactions are therefore much higher for commercial vehicles. As is evident from the business rules of the department, data is added and modified frequently for a specific applicant during the process of the initial application. Subsequently, data is again added to or the database modified after an interval of one month for the same applicant. Thereafter, fresh data is added to the database or the database modified only after a period of five years when the applicant comes back for renewal.However, there is always the possibility that someone loses or misplaces his or her license and comes back to have a duplicate issued. But when the scenario of multiple applicants who can come in at any day for fresh, duplicate or renewal of licenses is considered, it becomes evident that transactions are not periodic or time bound but are continuous. Transactions can happen any time during working hours resulting in changes to the database of the system. Taking only complete backup of the system would not be the optimal backup solution under the given circumstances.Whatever frequency of complete backup is adopted, the chance of losing data will be very high in the case of database failure or any other disastrous event that results system failure or corruption. Moreover, taking complete backup of the system very frequently would be a laborious and cumber some exercise. The ideal backup method in this case would be incremental backup in which backup is taken of only the data that is added or modified the moment it is added or modified, and a complete backup is taken at a periodic frequency.Under the situation, the Motor Vehicles Department has opted for continuous incremental backup with a complete backup taken at the end of the day. As a Business Continuity Plan measure, the department uses a remote backup mirroring solution that provides host-based, real-time continuous replication to a disaster recovery site far away from their servers over standard IP networks. This mirroring process uses continuous, asynchronous, byte-level replication and captures the changes as they occur. It copies only changed bytes, therefore reducing network use, enabling quicker replication and reducing latency to a great extent.This remote mirroring solution integrates with the existing backup solutions, and can replicate data to perform remote backups a nd can take snapshots at any time without having any impact on the performance of the production severs. It replicates over the available IP network, both in LAN and WAN, and has been deployed without any additional cost.

Database Processing Efficiency versus Database Storage EfficiencyThough storage costs as such has decreased dramatically over the years, the controversy between database processing efficiency and database storage efficiency continues to be an issue because the overall performance of a systems is affected by the way data is stored and processed. In other words, even though the volume of storage space available may no longer be a constraint financially and physically, the way this space is utilized has an impact on the database processing efficiency which in turns affects the overall performance of the application or the system.Und er the present circumstances, though it is possible to compromise on the side of database storage efficiency to derive greater database performance efficiency and thus improve the overall performance of the system, achieving optimization of the overall performance of a system requires striking a fine balance between database processing and database storage efficiency. There can be many tradeoffs between data processing speed and the efficient use of storage space for optimal performance of a system. There is no set rule on which tradeoffs to adopt, and differs according to the practical data creation, modification and flow of the system.Certain broad guidelines can however be followed in order to increase the overall utility of the database management system. Examples of such guidelines are to be found in the case of derived fields, denormalization, primary key and indexing overheads, reloading of database and query optimization. Derived fields Derived field are the fields in which data is obtained after the manipulation or operation of two or more original fields or data. The issue at stake is whether the data should be stored only in the original form or as the processed data in derived field also.When the data is stored only in the original form, the derived field is calculated as and when required. It is obvious that storing derived data will require greater storage space but the processing time will be comparatively less i. e. storage efficiency will be low whereas processing efficiency becomes higher. However, the decision on whether to store derived fields or not depend on other considerations such as how often the calculated data is likely to change, and how often the calculated data will be required or used. An example will make will serve to make matters more clear.A university student’s grade point standing is a perfect example of the derived field. For a specific class, a student’s grade point is obtained by multiplying the points cor responding to the grade of the student by the number of credit hours associated with the course. The points or the grade and the number of credit hours are therefore the original data, by multiplying which we get the grade point or the derived field. The decision on whether to store the derived field or not, will in this case depend on how often the grade point of a student is likely to change, and how often the student’s grade points are actually required.The grades of a student who has already graduated is unlikely to undergo nay more changes, whereas the grades of a student still studying in the university will change at regular frequency. In such a case, storing the grade points of an undergraduate would be more meaningful than storing the grade points of a student who has already graduated. Again if the undergraduate’s grades are reported only once a term, then it may not be worth it to store grade points as derived fields. The significance of the matter is realiz ed when we consider a database of thousand of students.The tradeoff in this case is between storing the grade points as derived fields and gaining on database processing efficiency and losing out on database storage efficiency on one hand; and not storing the derived fields and gaining on storage efficiency but losing out processing efficiency on the other. Denormalization Denormalization is a process by which the number of records in a fully normalized database can be considerably reduced even while adhering to the rule of the First Normal Form that states that the intersection of any row with any column should result in a single data value.The process of cutting down multiple records into a single record is applicable only in certain specific cases in which the number and frequency of transaction is known. Normalization of a database is required to maintain the accuracy and integrity of the data which in turn leads to validity of the reports generated by the system and the reliabi lity of the of the decisions based on the system. Denormalization, if done randomly can upset the balance of the database while economizing on storage space. The dilemma of Indexing Unplanned use of primary key has a telling negative affect on the database storage efficiency.Many database systems resort to setting index on a field. When a field is index, the system sets a pointer to that particular field. The pointer helps in processing the data much faster. However, indexing fields also results in the system storing and maintaining data but also information or data about the storage. The question therefore again boils down to deciding on whether to achieve higher processing efficiency by compromising storage efficiency or to enable higher storage capabilities at the cost of processing efficiency.Sorting the data periodically is one way of overcoming the dilemma of indexing. However, sorting itself is highly taxing on the resources of a system. Moreover, in large organizations with millions of data, a sort may take even up to hours during which all computer operations remain suspended. Other factors Storage efficiency and processing efficiency are also interdependent in other ways. The deletion of data without reloading the database from time to time may result in the deleted data actually not being removed from the database.The data is simply hidden by setting a flag variable or marker. This results not only in low storage efficiency but also in low processing efficiency. Reloading a database removes the deleted data permanently from the database and leads to smaller amount of data and a more efficient use if resources thereby boosting processing efficiency. Similarly, haphazard coding structures can impact negatively both on the storage efficiency and the processing efficiency of a database. Completely ignoring storage efficiency while prioritizing processing efficiency, can never lead to database optimization.Conversely, optimization can also never be achie ved by an over emphasis on storage efficiency. The objective is to strike the right balance. The interrelationships between database storage efficiency and database processing efficiency therefore keep the controversy between the two alive in spite of a dramatic decrease in storage costs over the years.
