Client/Server database

The client-server model consists of three parts,they are as follows,

1. Client
2. Server
3. Network

1. Client : The client is the machine running the front-end applications. The client has no direct data access responsibilities. It simply requests processes from the server and displays data managed by the server.
2. Server : The server is the machine that runs the DBMS software and handles the functions required for concurrent, shared data access. The server receives and processes SQL and other query statements originating from client applications.
3. Network : The network enables remote data access through client-server and server-to-server communication.

Advantages:

• It enables wider access to existing databases
• Increased performance
• Hardware costs may be reduces
• Communication costs are reduces
• Increased consistency
