The document introduces database management systems (DBMS) as collections of interrelated data and programs for efficient data access. It discusses the applications of DBMS in various fields, such as accounting, banking, and telecommunications, as well as the limitations of traditional file processing systems, including data redundancy and security issues. The lecture highlights the importance of application programs in managing data for university needs.

5. Keeps information about instructors, students, departments and
course offerings.
One way to keep information is to store in operating system
files.
To allow users to manipulate the information, the system has
number of application programs that manipulates the files.
Programmers develop these application programs to meet the
needs of the University.
New application programs are added to the system as the need
arises.
