The
database system approach has the following advantages
•
Data independence
The
data are logically designed into databases and they are independent of
applications. Since the data are program independent, any application can use
them without any modification to the code.
•
Data shareability
Database permits simultaneous multiple access
to the database. Thus, multiple users can share the same data.
•
Data integrity
Access
to the database is controlled by the database management system. The system authorizes
personnel for entering, editing and deleting data. It also authorizes people to
access data for various data processing activities. Since the database stores
one data item only in one place and updates it with fresh transaction data
automatically, there is little chance of inconsistency in the database.
•
Data availability.
The
database is centrally controlled and access to data is permitted through an authorization
scheme. The data resources are therefore available to the
users in the organization subject to the authorization procedure.
• Data evolvability
The database is flexible and can store huge quantity of data. It
can evolve as the number of applications and queries increase to meet their
data requirements.
