Before the Advent of Databases

In this lesson we will discuss the history of databases and the system used before its inception.

The way computers manage data has come a long way over the last few decades. Today’s users take for granted the many benefits found in a database system.

These application programs have been written at the request of the users in the organization. The system just described is called the file-based system.

Consider the example of a university management system that uses the file-based system to manage the organization’s data shown in the figure below:
