DISADVANTAGES OF DBMS:

• Complexity

Replication is the main cause of complexity. The functions that are expected to be provided by a DBMS make the DBMS complex. It leads to less performance.

• Cost

Due to the complexity of the system even the cost increases. Different DBMS have different costs which depend on the functions provided.

• Performance

DBMS is not written for a specific application. Hence all the applications do not run fast as they used to be.

• Size

Mainly the functionality of the DBMS makes it a large piece and finally occupies more amount of space in the memory.

• Impact of failure

The vulnerability of the system is increased because of the centralized resources. If some components fail then the operations will be halted in DBMS.
