What is Database

   A database can be thought of as a set of logically related files organized to facilitate access by one or more applications programs and to minimize data redundancy. This concept does not imply that all data relating to a company’s business should be contained on a single database, but simply that all records in a database should be related and that redundant data should be minimized.

General Objectives

   The elimination of data redundancy is only one of many reasons for establishing a database. Others include:

  • Integrate existing data files
  • Share data among all users
  • Incorporate changes easily and quickly
  • Simplify the use of data files
  • Lower the cost of storing and retrieving data
  • Improve accuracy and consistency
  • Provide data security from unauthorized use
  • Exercise central control over standards
