===================================================

we are also need to know
about database management system..
what is database management system?
database management system (DBMS)
To organize, manage, and retrieve data.
DBMS programs have five subsystems:
~one~
DBMS engine
~two~
data definition
~three~
data manipulation
~four~
applications generation
~five~
data administration
================================================
eitteeee....
hey...i also want to share about
WHY WE NEED DATABASE??
~1~
We need to share data of all kinds between users (except for very small systems), between tools working on them, and usually between different computers. All should be able to work with the same set of data.
~2~
We need persistent storage and storage must be reliable.
~3~
Several users and/or several tools must be able to safely access the same data concurrently.
~4~
A DBMS may provide more efficient access to large amounts of data, through indexing and other optimizations.
~5~
A DBMS and its data model provides an abstraction; we do not need to care about the physical storage format.
~6~
A DBMS may also be used for communication between different users or applications.
==================================
