Security and DML Data Control Language Essay Example

Security and DML Data Control Language Paper The security is a very important feature of any table mainly because when there are multiple people that require access. Any of these people may only need access to a specific table to edit the information and placing limitations on this access enables the database manager to maintain better control of any of the sensitive information as well as to ensure that the data is accurate and integrity. I think a class scheduler, for example, would only need access to the table that has the times and the dates for a specific class or classes. For this person, it is most likely one of the few with information to edit or make accurate changes to the table. Second, if they have a specific job as the schedule, they most likely wouldn’t require access to other tables. Therefore, by closing access to the other tables in the database, it can be definitively distinguished that the information has the altered or changed any of the other information besides from what they have access to. However, I think by utilizing methods such as SQL Data Control Language (DCL) commands, assignments can be given to configure both the security and integrity constraints of the database. Also, it makes sure that these commands ensure that all data remains secure and consistent. When access to certain databases is requested I believe that the mixed authentication is the best method to use. The mixed mode will enable both Windows Authentication and SQL Server Authentication by creating a more robust security layer. For instance, a Username and password is required for selection which will need to be uniquely identifiable to that specific user and it also contains multiple characters in it. It will ensure that the operating system token along with the username and password is required every time access is requested into a database.

Free Essays on The Migration of Foreign Industries to Mexico

The migration of foreign industries to Mexico has been an important issue for the Mexican economy. Much of the Mexican-US border region is in the midst of an industrialization period that shows no signs of slowing. In some areas, many U.S. and foreign companies are seeking: low-wage workers, low operating costs, fewer union restrictions, and a strategically located platform from which to launch products into the American market. What is a maquiladora? (â€Å"maquilas†) Maquila is the short form of the word maquiladora. It was originally associated with the process of milling. In Mexico it became the word for another kind of processing the assembly of imported component parts for re-export. The maquilas in Mexico began as a border phenomenon over 30 years ago. With the support of the Mexican government, US firms set up assembly plants on the Mexican side of the border. They were allowed to import components and raw materials duty-free and re-export the finished product to the US. The Maquiladora industry began in May 1966 with the passage of the Border Industrialization Program. This program made it economically profitable for American businesses to establish operations in the northern Border States from Tijuana Mexico to the border towns near Texas. In Mexico, American maquilas have found a cheaper workforce. This has been one of the greatest motives for American industries to go to Mexico. With what a normal American worker gains in one day, a Mexican worker can be paid a whole week. If this is looked at in a future perspective, the maquila is going to make and gain more money over the years. This money can be used for many things; for example, for improving the installations, to give the worker better pay, to buy more infrastructures or just to save it for future investments. The existence and development of the maquiladora industry in Mexico is due primarily to foreign investment. There are many countr...

MAI Systems Corporation Case Study Example | Topics and Well Written Essays - 2000 words

MAI Systems Corporation - Case Study Example Recently, Softbrands purchased the Company back in August 2006. Since its inception in 1957, the Company has gone through significant changes. Being an opportunist and thanks to IBM and the Justice Department in 1956 when the entire computer industry was under the monopoly of IBM, Walter R. Oreamuno and his associate came up with an idea of re-purchasing the computer equipment from IBM customers and leasing it back to the customers at a lower rate than what was being offered by IBM. This idea was a great boast to the MAI's growth but did not last that long. During this time, the Company opted for an IPO with an Not realizing IBM's strategy of depreciating its punch card equipment and the innovation of 360 third generation computer, MAI invested substantially in the older equipment that resulted in MAI's growth to stall. During 1967, a major setback on merger plans with Transamerica, Oreamuno stepped down as the CEO and was replaced by Luther Schwalm an ex-IBM veteran. With a shift in strategy, the earlier investment in the older IBM equipment did not prove to be fertile, Schwalm decided to write-off the outdated older equipment. MAI's cash flow was impacted so substantially that its net worth in 1970 was negative $ 28 million. Oreamuno's decision proved out to be so wrong that even Schwalm was unable to bring the Company out of trouble. It was that when in 1971 MAI's CFO took over as the President. With a new strategy, Kurshan reorganized MAI into a holding company with various subsidiaries. Basic/Four and Sorbus subsidiaries of MAI did well in bringing MAI back to life. Sorbus took advantage of MAI's existing 1,200-person maintenance staff as its core, and expanding from there. Basic/Four was a major success instantaneously. In 1972, Basic/Four introduced the first multi-user transaction-processing mini-computer to use the Business Basic language. Basic/Four's revenue grew up to $43 million, and it was contributing around two-thirds of MAI's tot al earnings. Focused on software products, MAI in 1977 took over acquired Word stream Corporation. This company was producing word processing systems and IBM-compatible CRT terminals. MAI shipped its 10,000th computer system in the year 1980. The market for these computers began to shift drastically at this time, and small companies were turning to cheaper, newly available personal computers instead of the mini-computers that had been Basic/Four's forte. In 1983, the company introduced its MAI 8000, a super-minicomputer nearly as powerful as a mainframe computer, which was proficient enough of servicing up to 96 users at one time. In 1984, a New York-based investor Asher Edelman purchased 12 percent of MAI's stock. Edelman by means of a proxy war for control of the company won four seats on MAI's ten-member board of directors. In the course of the proxy battle, Edelman received a settlement in the $1 million range following a libel suit filed against MAI concerning company advertisements. During April 1984, MAI International Corporation, the company's worldwide marketing arm, was folded into

The American Beaver as a keystone species and there effect on the Essay

The American Beaver as a keystone species and there effect on the north american ecosystem - Essay Example This paper purposes to explore how the animals achieve this great impact. The American Beaver is considered as a keystone species in the North American wetland areas by the ecologists. Keystone species are animals whose activities and abundance determine the integrity of the community and its unaltered persistence through time (Schulze 238). The activities of the American Beaver result to creation of dam and reduction of the flowing speed of streams. Moreover, it results to deposition of sediments on the beds of those streams. This improves the ecosystem of the fish and other water animals in those streams. Therefore, the activities of these animals improve the living conditions of the other water animals and hence they are keystone species. Moreover, the activities of the American Beaver also have an impact to the animals living in both the riverbanks and those living on the other landscape. This is because these animals have the capability to influence the course of succession, species composition, and structure of plant community (Rosell et al 2). These animals can change the composition of plant in an area thus bettering the habitant for other animals. Their foraging also clears the land thus making the ecosystem very favorable for the predators. However, they sometimes fall trees that can destroy the ecosystem of the birds. Therefore, the activities of the American Beaver have an influence to the community of the terrestrial animals also and thus it is a keystone species. The American Beavers activities results to felling of trees on streams that block the streams thus converting the flood plains of streams into wetlands. The activities of these animals have resulted to creation of several wetlands on areas that were previously occupied by flood plains. In other areas, their activities have resulted to expansion of the existing wetlands. This has been mainly through the felling of trees

The Power of a Magnifying Glass Essay Example for Free

The Power of a Magnifying Glass Essay The magnification of a magnifying glass depends upon where it is placed between the users eye and the object being viewed, and the total distance between them. The magnifying power is equivalent to angular magnification (this should not be confused with optical power, which is a different quantity). The magnifying power is the ratio of the sizes of the images formed on the users retina with and without the lens.[3] For the without case, it is typically assumed that the user would bring the object as close to the eye as possible without it becoming blurry. This point, known as the near point, varies with age. In a young child it can be as close as 5 cm, while in an elderly person it may be as far as one or two metres. Magnifiers are typically characterized using a standard value of 0.25 m. The highest magnifying power is obtained by putting the lens very close to the eye and moving the eye and the lens together to obtain the best focus. The object will then typically also be close to the lens. The magnifying power obtained in this condition is MP0 =  ¼ÃŽ ¦ + 1, where ÃŽ ¦ is the optical power in dioptres, and the factor of  ¼ comes from the assumed distance to the near point ( ¼ m from the eye). This value of the magnifying power is the one normally used to characterize magnifiers. It is typically denoted mÃâ€", where m = MP0. This is sometimes called the total power of the magnifier (again, not to be confused with optical power). Magnifiers are not always used as described above, however. It is much more comfortable to put the magnifier close to the object (one focal length away). The eye can then be a larger distance away, and a good image can be obtained very easily; the focus is not very sensitive to the eyes exact position. The magnifying power in this case is roughly MP =  ¼ÃŽ ¦. A typical magnifying glass might have a focal length of 25 cm, corresponding to an optical power of 4 dioptres. Such a magnifier would be sold as a 2Ãâ€" magnifier. In actual use, an observer with typical eyes would obtain a magnifying power between 1 and 2, depending on where lens is held. Using this principle, a magnifying glass can also be used to focus light, such as to concentrate the suns radiation to create a hot spot at the focus.

Ayn Rand, Aristotle, and Selfishness :: essays research papers

Ayn Rand, Aristotle, and Selfishness Selfishness is an act that humans innately have implanted within them. Ayn Rand being a rational egoist had many moral beliefs, one being especially about selfishness. She believed that: â€Å"Self-interest, properly understood, is the standard of morality and selflessness is the deepest immorality.†( Ayn Rand 279) This basically emphasizes that you should see oneself, as an end to oneself. A person’s own life and happiness are their highest values, and that they don’t exist as servants or slaves to the interests of others. In the same way, others as well don’t exist as servants or slaves to a person’s own interests. Each person's own life and happiness is his/her crucial end. Ayn Rand, Aristotle, and Frederick Nietzsche all had theories behind this, which was that Humans are innately selfish. Threw out society today all humans are selfish and it is proven by these philosophers that it is naturally developed and there is no cure to prevent it. Ayn Rand, a great Russian philosopher, once questioned why shouldn’t one be selfish. Ayn Rand responded to that question with her theory which she called objectivist ethics. This theory states that humans are innately selfish. â€Å"Everyone does what they really want to do otherwise, they wouldn’t do it†.(Ayn rand 66) Rand believed that humans are rational beings and maintained the idea that rational people will help others if they get something in return. This idea is a voluntary co-operation, which applies to dealings with trade and justice. It also applies to human relationships. In developing her theory she criticized the ethics of altruism, which says that people should act out of selfish concern for others. Ayn Rand says in her book called â€Å"The Virtue of Selfishness† that the proper method of judging when one should help another person is by reference to one’s own rational self-interest and one’s own hierarchy of values. Ayn Rand followed Aristotle’s point of view. However unlike Aristotle she focused on an individual other than a community. â€Å"There is no such thing as ‘society’ †¦ only individual men† (Ayn Rand 279) Ayn Rand followed her great acknowledged teacher Aristotle. She changed her view slightly different from Aristotle which was to focus on an individual rather than focusing on a whole community. Aristotle believed that one’s own life is the only life one has to live for. Aristotle also stated that the â€Å"good† is what is objectively good for a particular man.

A Social Family Institution in India

Location: India has an area of approximately 3,287,580 sq. kilometers. It serves as a border to the Bay of Bengal the Indian Ocean, and to the Arabian Sea located to its west. Directly north of India are the Himalayas, the world†s biggest mountain range. India also serves as a neighbor to several different countries. Myanmar and Bangladesh located to its east, China, Nepal and Bhutan to the north, Sri Lanka to the South, and finally Afghanistan and Pakistan on the northwest. Topography: India is separated into 4 main regions, these are the Ganges, Indus Plains, Desert zone, and the Southern Peninsula. Physiologically India is divided ten times. A senior male usually heads families in India. In the senior males household a family can be very large. The senior male†s family can include his unmarried children, married children alongside their wives and kids, unmarried younger brothers and sisters, and married brothers with their wives and children. It is common however for families to separate once the father dies. This idea of family is true for both nuclear family and extended family. As already stated above the size of a typical Indian family is very large. The senior male is responsible for providing the financial assistance to the family while his wife takes care of the house. She assigns chores to all of the females in the household. The Elderly are taken care upon dearly by their family members. The marriage traditions in India have been in existence for a very long time. The have a long and important set of rules that are carefully followed by most. A marriage arrangement is a big responsibility for the parents of both the female and male. A marriage is arranged based primarily on religion, family wealth, and the hope for a good biological reproduction. Marriages in India are no different than in most of the countries around the world. It is a very special event for the bride and grooms family and friends. For both the male and the female marriage is a big change not only socially but mentally as well. Only once married is one truly considered to have made the transition to adulthood. Married couples display a strong for male children. Males are desired more because of financial contribution the may supply for the family. Girls on thew other hand are some times viewed as very big liabilities, The more one has the more liable one is. They are viewed as very expensive to support and require very expensive dowries once they are married. Families that have many girls and very few or no males are in great danger of experiencing financial disaster. The roles played by males and females in the Indian society have a very strong presence. Their roles have changed very little in the last couple of decades. Males are the dominant sex in the society. Females have very little power or control over their lives. The male†s main role is to provide financial stability. India†s educational system is one that is very similar to that held by the British. It consists of five levels of education. Level one is preprimary, followed by primary (which in the American system would equal grades 1-5), middle class (middle school), secondary (9 and 10 grades), and finally higher levels (11 and 12 grades). India s governments is currently working very hard to make the peoples education a top priority. The Indian government supplies the people with free education, even with free education only about half of the children attend school. It is viewed by the Indian people that it is more important for the males to attend school than it is for the females. Out of the 50 Indian population is illiterate, 66% of these are females. Higher education in India is not very big. Out of all of the people that attend primary and secondary education less than 10% go on to higher education. It†s popularity however is increasing greatly compared to past years. India†s collegiate system is divided into three. One of these three types is the religious college. These are colleges found by politicians and by wealthy families. They did this in order to gain popularity amongst the people. Government colleges constitute the second type; these are colleges that are found on the outskirts of big cities. They lack private investments and are therefor founded by the government. The third type is called Professional colleges. These are colleges that mainly receive both government and private aid. Professional colleges are the beset of colleges to study carriers such as medicine, engineering etc. 2-India Literacy rate is very high in numbers but very low in percentages. They have over 400 million people that can read but this constitutes only about 56% of the population. 1- India runs its government under a constitution created in 1949. The president of India is elected by the parliament and serves a term of five years. The Prime Minster of India is also a very powerful man in this country. It is said that he has more power than the president. Lok Sabah, otherwise know as the Lower House of Parliament is controlled by the ministers. The federal Parliament consists of no more than 250 members. The President appoints twelve of them and most of the others are appointed by their state. The Lower House has no more than 545 members. Just like the president they serve terms that last fore five years. In case of a national emergency the president can overrule any state government.
