What is Database?
A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images. The purpose behind the database is to provide an easy mechanism for storing, managing and retrieving information. Database management systems achieve these functionalities with the help of Tables. A fine analogy for the tables can be the Microsoft Excel sheet with grids. Tables in relational database consist of columns and rows. Each column has a different type of attribute and each row is a single record. For example, a record can be an entry with in a database with names and telephone numbers. We would probably set up columns named as First Name, Last Name and Telephone Number. If we were building a table of contact information for our business that has 50 employees, we would d wind up with a table that contains 50 rows.
