Types of database system with example:
what are the 4 types of database
There are four types of database as shown below:
- Centralize DBMS
- Parallel DBMS
- Distributed DBMS
- Client server DBMS
Centralize DBMS : The centralized DBMS system consist of a single processor together with its associated data storage devices and other peripherals.
Advantage - Data can be accessed from the different location with the use of a computer network while the database is maintained ass the central sight.
Disadvantage - Communication cost from the terminals to the central sight can be expensive.
Parallel database system : It consist of a multiple CPU ,and data storage disk in parallel.
Advantage - These are very useful for the application on extremely large databases.
Distributed database system : Physical distribution of share data at different location over a computer network is called as distributed database.
Advantage - it provides greater efficiency and better performance.
Disadvantage - recovery from failure is more complex in distributed database system than in centralize system.
Client server DBMS : It contain two components one is client and another one is server.
Application programs are kept at client side while databases and database management software are kept at server side.
The server and client computers are connected to a network.
Advantages -
- More flexible compared to centralized database system.
- It provides high throughput and better response time.
- Client - server programming cost is high.
- Security needs to be implemented in a way.
