Exercise 1.1 Why would you choose a database system instead of simply storing data in operating system files? Data Access: DBMS provides efficient access of data, faster retrieval of data when compared to file systems, as DBMS provides indexing and query optimization mechanisms which provide efficient access.
Why do we need database instead of storing data in a file system?
File processing system has more data redundancy, less data redundancy in dbms. File processing system provides less flexibility in accessing data, whereas dbms has more flexibility in accessing data. File processing system does not provide data consistency, whereas dbms provides data consistency through normalization.
Why is database system necessary?
Databases support good data access because: Large volumes of data can be stored in one place. Multiple users can read and modify the data at the same time. Databases are searchable and sortable, so the data you need can be found quick and easily.
