Q. What is a database system? What is its need?
Answer =
A database is a collection of interrelated data and a database system is basically a computer based record keeping system.
A typical file processing system suffers from some major limitations like data redundancy (Duplication of data), data inconsistency, unsharable data, unstandardized data, insecure data, incorrect data etc. On the other hand, a database system overcomes all these limitations and ensures continuous efficiency.
The advantages provided by a database system are:
(i) Reduced data redundancy
(ii) Controlled data inconsistency
(iii) Shared data
(iv) Standardized data
(v) Secure data
(vi) Integrated data.
Therefore, to have the systems with increased performance and efficiency, the database systems are preferred.
