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.
