Database in network environment

A Network architecture ¹⁴ in which each computer or process on the network is either a client or a server.

Servers are powerful computers or process dedicated to managing disk drives (file servers), printers (print serves), or network traffic (network servers).

Client are PCs or workstations on which users run applications. Clients rely on servers for resources, such as files, devices, and even processing power. Another type of network architecture is known as a peer-to-peer architecture because each node has equivalent responsibilities.

Both client/server and peer-to-peer architectures are widely used, and each has unique advantages and disadvantages. Client-server architectures are sometimes called two-tier architectures.

Client/server describes the relationship between two computer programs in which

one program, the client, makes a service request from another program, the server, which fulfils the request. Although the client/server idea can be used by programs within a single computer, it is a more important idea in a network. In a network, the client/server model provides a convenient way to interconnect programs that are distributed efficiently across different locations.

A database server is a computer program that provides database services to

other computer programs or computers, as defined by the client-server model.
