Disadvantages of distributed database
Complexity. A distributed database is more complicated to set up and maintain compared to a central database.
Security. There are many remote entry points to the system compared to a central database
Data integrity. More complex to make sure data and indexes are not corrupted.

Not so efficient if there is heavy interaction between branches, in which case a central database is the better option.
