Abstract
This paper discusses the increasing need for easy to operate database management systems and reviews the products currently available in the market. The three main players in this field are IBM, MICROSOFT and ORACLE.

Abstract
The paper relates that the database management system (DBMS) is vitally important for businesses, governments, and consumers; DBMSs power everything from e-commerce transactions to the data mining functions that allow governments to identify tax cheats to personal websites. The paper notes that despite the ubiquity of DBMSs, few laypeople understand what they are, or what they do. This paper serves as an introduction to the history, purpose, and future of the DBMS.

"The database management system (DBMS) is vitally important for businesses, governments, and consumers; DBMSs power everything from e-commerce transactions to the data mining functions that allows governments to identify tax cheats to personal websites. Despite the ubiquity of DBMSs, few laypeople understand what they are, or what they do. This paper will serve as an introduction to the history, purpose, and future of the DBMS. DBMSs would not be possible without the database itself. The database is a software application dating from 1960s research conducted by IBM (Wilton and Colby 2005, p. 7) that allows information to be stored in a highly..."

Abstract
This paper explores the nature and benefits of CVS' current database management system and relates that the Rx system used in locations all over the country proves to be very effective in reducing effort and time to correlate both prescriptions and insurance information and also proves easy to use and cost effective. However, the paper asserts that the recent leaks of confidential patient information have made a better security system absolutely necessary to continue the success of the system within Caremark's CVS pharmacies.

Abstract
The paper explains the development, function, and purpose of database management systems. It explains the differences between the two major types of database management systems and evaluates some of their strengths and weaknesses. A comparison chart of database management systems is included at the end of the paper.

From the Paper
"Object-oriented database management system (ODBMS) vendors were hopeful that future applications would be implemented with pure object-oriented systems (Devarakonda, 2001). Initially, these systems looked promising, but they were unable to live up to the expectations. A new technology has evolved in which relational and object-oriented concepts have been combined or merged. These systems are called object-relational database management systems (ORDBMS). ORDBMSs best ODBMSs in most situations because they can provide massive scalability as well as object-oriented features. Today, ODBMS use is mostly confined to niche applications where the data being managed falls into hierarchical structures with numerous and somewhat unpredictable relationships between data objects."

Abstract
This paper explains that Object-Oriented Database Management Systems (OODBMS), which emerged in the 1990s, quickly found their niche in handling complex data types; however, the long-term vision of OODBMSs to replace relational databases has never materialized. The author points out that OODBMS technology remains a small niche market, generating only around a few hundred million dollars in revenues, compared to the multi-billion dollar relational database market. The paper states that the goals of large relational database vendors, such as Oracle, IBM, and Microsoft, have been to synthesize the best of relational databases and OODBMs, such as the flexibility of the OODBMS data model and the performance of relational database functions, into an Object-Relational Database Management System.

From the Paper
"OODBMSs first started to be researched in the 1980s and the first commercial products gradually appeared in the early 1990s from vendors such as Object Design, Objectivity, Versant, Computer Associates and Ardent. By the late 1980s and early 1990s it was recognized that object oriented (OO) languages had some very strong advantages over non-OO languages for many programming applications. OODBMSs emerged to reduce the impedance mismatch between the programming languages and the DBMS, to offer performance advantages (due to navigation from roots and sophisticated caching and swizzling technologies), and to provide transparent support for complex user-defined types including the ability to store, call and query complex objects directly."

Abstract
In today's information-rich society, database management is an ever-expanding and increasingly important field. This paper discusses databases, database management systems (DBMSs), and their importance in today's society. Additional topics include the need for security, concurrency, and control within database management, as well as the role of the database administrator.

From the Paper
"A database can be defined as "a structure that can house information about multiple types of entities, the attributes of these entities, and the relationships among the entities" (St. Edward's University). Databases can contain a wide variety of information. For example, a university database may include information about students, courses and classrooms. Further, this university database may contain significant amounts of information about the relationships between these entities, such as student course enrollment, and the use of classrooms for courses (Ramakrishnan)."

Abstract
This paper discusses on-line information technology and the problems that exist in database security. It continues to offer solutions to this problem, in discussing legislation, software and hardware to protect information databases from the illegal and malicious threats that effect them.

Bibliography

From the Paper
"There are many measures and security policies that can be implemented to prevent illegal access to private databases. Typically, every security policy is dependent on the other policies. It is important to note that security policies work best if all the policies embedded within have strong walls against unauthorized access. Otherwise, once one policy fails, there are tendencies that its vulnerability and failure to protect the network, database, or information, can affect the rest of the policies. Following are some of the common policies, as extracted from Oracle Server Administration Guide, that are applied by many organizations which utilize information technology methods for database and information safety and security."

Abstract
This paper discusses the use of an enterprise database management system and outlines the ways in which it can be used by a government contracting company to expand its business. The paper also highlights the attracting features and functionality offered by a DBMS and explains how it can improve activities at strategic, tactical and operational levels.

From the Paper
"A DBMS renders the interface between the application program and the data. If the Government Contracting Company plans to expand its business, then a DBMS would make the data representation for the users and the developers a lot easier. If any changes are made to the data representation, the metadata maintained by the DBMS would automatically be modified and the DBMS would persevere to render data to application programs in the usual manner. "Hence, unlike previous databases the DBMS handles the task of transformation of data wherever necessary" (Gopal Gupta, Advantages Of Using A DBMS). The independence provided by the DBMS between the program and the data is referred to as data independence."

Abstract
This paper discusses trends in data management and problems associated with data management, such as problems associated with too much or too little data.

From the Paper
"Too much data can be a problem with database storage. When there is too much data, the data becomes an impediment that stands in the way of seeing and understanding the data that is important to the business. Thus, it is vital to keep data pared down to what is really usable and helpful. With too much data, information systems can become bogged down and system turnaround time can slow, there is a greater chance of the wrong data being used..."
