in modern society. In course of a day, most of us encounter several activities that involve some interaction with database such as bank, supermarket etc.
To understand the fundamentals of database technology, however we must start from the basics of traditional database applications. We will start with what is database and other definitions .Then we will study characteristics of database systems and categorize the types of personnel whose jobs involve using and interacting with database systems
