Purpose of Database Systems
Purpose of Database Systems
• Nowadays organizations are data-dependent. efficient
management and retrieval of information play a crucial
role in their success.
• A database is a collection of data that is organized, which is
also called structured data.
• It can be accessed or stored in a computer system. It can
be managed through a Database Management System
(DBMS), a software used to manage data.
• DBMS is the most suitable technology that provides
services like storing, organizing, and manipulating huge
amounts of data.
The purpose of DBMS is to transform the
following −
• Data into information.
• Information into knowledge.
• Knowledge to the action.
• Previously, the database applications were
built directly on top of the file system.
• Drawbacks in File System
• There are so many drawbacks in using the file
system.
These are mentioned below −
• Data redundancy and inconsistency: Different file
formats, duplication of information in different files.
• Difficulty in accessing data: To carry out new task we
need to write a new program.
• Data Isolation − Different files and formats.
• Integrity problems.
• Atomicity of updates − Failures leave the database in an
inconsistent state. For example, the fund transfer from
one account to another may be incomplete.
• Concurrent access by multiple users.
• Security problems.
