For this week’s paper I have chosen to do a comparison between IBM’s DB2 database management system (DBMS) product and Oracle. Realistically, making such a comparison is akin to discussing religion with friends. Each person will have their own biases based on their own experiences. Looking for an unbiased opinion is much like looking for the Holy Grail, every bit as speculative and subjective with the results jaundiced by the outlook of the reporter (Lim, 2002).
A decision between DB2 and Oracle should be based on what resources are available for use at the site. Is there specific hardware or software already onsite that can or will be used in the installation, if so this will have a major impact on the decision making process. Does the staff have an existing knowledge base that favors one or the other DBMS and is there a team that has unallocated time to dedicate to this project or will another project be put on hold to allow them to make this project their focus until completion. Finally, have the costs of ongoing maintenance for fixed and soft assets been considered? All of the above will impact the decision making processes prior to purchasing one of the DBMS’s. These factors aside, either DBMS will run as fast as the other provided that the environment has been optimized for it (Lim, 2002).
A side by side analysis of the hardware and software requirements for both DBMS’s shows some remarkable similarities as well as some differences. Similarities in baseline processors across the various hardware platforms but different amounts of disk space and both applications desiring as much memory as possible to improve performance (Chigrik, 2003).
For DB2 v8.1 when installed into a windows environment you will need a minimum of a Pentium or Pentium compatible processor, at least 256mb of ram, and between 100 and 350mb of hard disk space depending on whether the installation is compact, custom, or typical. Depending of the file format of the disk drives additional space may be needed by DB2 because of cluster sizes (Chigrik, 2003).
Oracle 9i on the other hand requires a minimum of 128b of ram in a windows environment, although 256mb is recommended. Oracle also requires a minimum of 200mb of virtual memory for file swap space. In terms of processors, Oracle specifies a minimum of a Pentium 166 or higher. Oracle also needs 140mb of disk space on the system drive an...

... block indexes. IBM DB2 has higher limits in most of the common database features except most columns in an index key, longest index key, max char() size, max table row length, longest SQL statement, and recursive sub queries (Chigrik, 2003).
In the end there is no clear cut winner, as stated previously, a lot of the outcome is determined by the experience of the developer of the database and the administrator of the database. Both DBMSs can be used to build stable and efficient transaction processing systems, with the level of experience of the personnel working with the system having a greater impact on performance, than the vendor supplying the DBMS (Chigrik, 2003).

Descartes explored the different relationships that exist between the senses, the imagination, and the understanding and while he cleared them, one thing still needs to be brought to light. It is only through calling into question and doubting our judgments ( brought to us by sense perception) that we avoid error, “ but since everyday pressures don’t always allow us to pause and check so carefully, it must be admitted that human life is vulnerable to error about particular things, and we must acknowledge that weakness of our nature” ( 35).
D. J., & Engles. C. R. (2010). The purpose of this research was to see if thin dolls have an effect if any, on young girls view of their body image. It also focused on the effects of food intake, after exposure to the thinner doll. The amount and type of participants used in this study were 117 young girls, from seven different schools in the southeast of The Netherlands, Anschutz. D. J., & Engles. C. R. (2010). Their age ranged from 6 to 10 years old. The measurement was done on a slimmer type of doll (Barbie), an average sized doll (Emme), and Legos in a controlled condition. This testing also required the girls to do a taste test, and questionnaires, Anschutz. D. J., & Engles. C. R. (2010). The independent variable for this testing was the images of the dolls. The dependent variables for this study consist of body esteem, actual ideal body size discrepancy, and food intake. The format for the testing consisted of facial pictures of smileys, which were for the responses to the statements. In order to measure actual-ideal body size discrepancy there were drawings of nine different figures of girls. They ranged from very thin to very fat. The third portion of the testing consisted of the food intake measurement, which required the girls to freely taste test three different bowls of chocolate-coated peanuts. The total amount of test food
Some faculties and departments are already using Oracle applications in their day-to-day operations. As time goes by, more and more information users will be working with an application based on Oracle database technology. If you get the opportunity to be a member of an application development team, you will become familiar with the workings of Oracle and relational databases. Other users may have to learn about this popular database management system through their own experience. This article is for our readers who, as of yet, have no access to Oracle databases but have a yearning for learning what they're all about.
To build this new CRM system, they had to merge 20 different databases into one multiterabyte repository with 50 million unique customer records, and used enterprise application integration tools, messaging middleware, rules engines and Java application server technology to integrate applications and transport data between various applications and the database
In 1977, Larry Ellison, Bob Miner, and Ed Oates founded System Development Laboratories. After being inspired by a research paper written in 1970 by an IBM researcher titled “A Relational Model of Data for Large Shared Data Banks” they decided to build a new type of database called a relational database system. The original project on the relational database system was for the government (Central Intelligence Agency) and was dubbed ‘Oracle.’ They thought this would be appropriate because the meaning of Oracle is source of wisdom.
Some have suggested that René Descartes argues that sense perception relies on the mind rather than on the body. Descartes asserts that we can know our mind more readily than we can know our body. In support of this idea he gives the example of a piece of wax which is observed in its solid form and its liquid form. After pointing out the difficulties of relying on the senses of the physical body to understand the nature of the wax he makes this claim: [P]erception ... is neither a seeing, nor a touching, nor an imagining. ... [R]ather it is an inspection on the part of the mind alone (Section 31). 1 This quote is perhaps the most direct statement of the author's thesis on this subject.
Although body dissatisfaction is most popular in young women, the age of onset is much younger. Cusumano and Thompson’s research (as cited in Dohnt & Tiggemann, p. 141) suggests that the age of onset is preadolescent girls (ages 8-11) where young girls start to feel body dissatisfaction and the idea of being thinner. In a study done to research body image in girls as young as 5-8 years old, it was found that concerns about bodies start at that young age (Dohnt & Tiggemann, 2006, p. 148). Because the desire to be thin starts at such a young age, it usually gets worse as girls get older. The more that they are exposed to the media as they get older has a lot to do with it. In another study, it was found that regardless of the media type,...

On December 10th in 1948, the general assembly adopted a Universal Declaration of Human Rights. This declaration, although not legally binding, created “a common standard of achievement of all people and all nations…to promote respect for those rights and freedoms” (Goodhart, 379). However, many cultures assert that the human rights policies outlined in the declaration undermine cultural beliefs and practices. This assertion makes the search for universal human rights very difficult to achieve. I would like to focus on articles 3, 14 and 25 to address how these articles could be modified to incorporate cultural differences, without completely undermining the search for human rights practices.
While on one hand there is a growing consensus that human rights are universal on the other exist critics who fiercely oppose the idea. Of the many questions posed by critics revolve around the world’s pluri-cultural and multipolarity nature and whether anything in such a situation can be really universal.
The universality of human rights is a concept. This impression embraces that human rights belong to all human beings and are essential to each type of society. By this, “Each individual has the same basic human rights. Individuals may exercise miscellaneous rights, or exercise the same rights differently; on the environment of the society or group. An assorted group consists of certain races, ethnicity, religion, children or women. ” (Article 22 United Nations Universal Declaration of Human Rights) As time progress the content of human rights changes over time however, the concept of their universali...
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
Almost all commercial database systems available today are designed to provide a high level of performance to its users. Nonetheless, Database Performance Tuning for large volumes of data is an arduous task. Even minor changes can bring about a substantial impact (positive or negative) on the performance of the system (KOCH, 2014).
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
