Client Server Database Systems:
Definition and Explanation:
Earlier multi-user architectures used mainframe
computer to process the database. The mainframe computer provides all the
functions to the connected users directly. The mainframe contains the DBMS
software, application programs, and user-interfaces. The users connected to the
mainframe through their terminals. The remote users were connected to mainframe
in communication networks.
In the mid 1980s, most users began to share data
through local area network (LAN). The microcomputers were linked together in a
LAN so that data and resources such as printers, storage devices, etc can be
shared. The LAN enabled the users to share data to one another through
computers. The first application of LAN enabled the users to share the resources
for communication via electronic mail. The end-users also wanted to share their
database, which led to the development of multiuser
database applications on
LANs. After this, the client-server architecture was introduced to share data
on-the computer network.
