A centralized database stores all data in a single location, typically on a central server, making it easy to get a complete view of data but slowing down with many users accessing the same file. A distributed database splits data across multiple physical locations and processing across nodes, avoiding bottlenecks while requiring synchronization and replication across locations.

2. A centralised database is a database that is located,
stored, and maintained in a single location. This location
is most often a central computer or database system, for
example a desktop or server CPU, or a mainframe
computer.

3. A distributed database is a
database in which portions of
the databaseare stored in multiple
physical locations and processing is
Distributed database among multiple
database nodes

4. Since there is only 1 database file, it is
easier to:
• Get a complete view of data
• Manage update an backup data

5. • Bottle necking from multiple users
accessing the same File –slowing down
productivity

6. Having Multiple database file means:
• Users won’t interfere with each other
when accessing/ manipulating data
• Speed since files are retrieved from
nearest location
• If one site fails , the system can still
run

7. • Time for Synchronization of the
multiple database
• Data Replication for each different
database
