DISADVANTAGES OF DBMS:
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.
Due to the complexity of the system even the cost increases. Different DBMS have different costs which depend on the functions provided.
DBMS is not written for a specific application. Hence all the applications do not run fast as they used to be.
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.
