Briefly describe the scenarios, where database management system should not be used?

Scenarios where Database Management System (DBMS) should not be used In spite of the advantages of using a DBMS, there are a few situations in which such a system may not be suitable: In situation where unnecessary overhead costs of using a DBMS is involved due to the following reasons: High initial investment in hardware, software, and training. Generality that a DBMS provides for defining and processing data. Overhead for providing security, concurrency control, recovery, and integrity functions. The database and applications are simple, well defined and not expected to change. There are tight real-time requirements for some programs that may not be met because of DBMS overhead. Multiple user access to data is not required. An application may need to manipulate the data in a way not supported by the query language.
