Introduction to Databases

-The database is now such an integral part of our day-to-day life that often we are not aware we are using one.
-We will use some terminology in this chapter :
database :a collection of related data
DBMS (database management system) : the software that manages & controls access to the database
database application : a program that interacts with the database at some point in its execution
database system : a collection of application programs that interact with the database along with the DBMS and database itself
