Why Database?

In computerized information systems data is the basic resource of the organization. So, proper organization and management of data are required for an organization to run smoothly. The Database management system deals with the knowledge of how data is stored and managed on a computerized information system. In any organization, it requires accurate and reliable data for better decision making, ensuring the privacy of data, and controlling data efficiently.

Examples include deposit and/or withdrawal from a bank, hotel, airline, or railway reservation, purchase items from supermarkets in all cases, a database is accessed.

In order to overcome the limitation of a file system, a new approach was required. Hence a database approach emerged. A database is a collection of logically related data. The initial attempts were to provide a centralized collection of data. A database has a self-describing nature. It contains not only the data sharing and integration of data of an organization in a single database.

A small database can be handled manually but for a large database and having multiple users it is difficult to maintain it, in that case, a computerized database is useful.

Advantages of Database systems over File System:

The advantages of a database system over traditional, paper-based methods of record keeping are:

  1. Compactness: No need for a large number of paper files
  2. Speed: The machine can retrieve and modify the data faster way than a human being
  3. Less drudgery: Much of the maintenance of files by hand is eliminated
  4. Accuracy: Accurate, up-to-date information is fetched as per the requirement of the user at any time.
