Centralized advantage

bugfree(BugFree)
1. data integrity. Bank need all data stored on the centeral data center.
2. Easy maintenance, can implement Single Sign On services, such as Kerberos, SESAME, KryptoKnight, NetSP

Centralized disadvantage
1. Data server is a Single point failure

Decentralized Advantage
1. Fast if data are stored distributed
2. If data link to centeral server is broken, operation will not be impacted

Decentralized disadvantage
1. Data consistance maintenance
2. User and file system management is a nightmare
3. System back and recovery is also a nightmare
