/380 Database Design Paper DBM/380 October ‚ 2012 University of Phoenix Database Design Paper A database is a set of programs and applications used to store data‚ this allows the data to be used by different individuals in different areas and access information from it quickly. A database stores the information so it can be used at a later time so additional information can be added‚ taken away‚ or used as needed. Once in the database the data is compressed so it takes up less space

Using a database management system (DBMS) is a wise decision for any business that plans to implement the use of a database as part of their IT infrastructure. A database management system‚ also referred to as a database manager (Rouse‚ 2005)‚ allows one or many computers to create‚ query‚ and manipulate data in the database (Rouse‚ 2005). The database management system also manages request from users and applications‚ making the database much more user friendly‚ since the users nor the applications

Object-Oriented Programming Paradigm Advantages * Because of the concept of inheritance in OO programming‚ existing codes can be easily modified because new codes can be added with little modifications made. That is to say it is easily extensible and codes can be easily re-used. * OOP provides a clear program structure because the solution to be developed can be broken down into objects and approached as such. This gives room for maintainability of the program because problems would be easy

Designing and coding a procedure‚ module‚ or object can be complex and time consuming. Once these elements of a computer program are working correctly‚ it makes sense to use the code as often as practical. Code reusability has become a valuable part of adding efficiency to computer programming. When it comes to solving the problem of code/data separation‚ the use of Object –Oriented Programming has played a big role in the rising of object reusability. An object is not considered a standalone program;
