What Is a Database?

You can define a database as a collection of data on one topic. It is organised in a way allowing to easily browse the information, make changes or add new items.

Look at this diagram for one of the above examples: a simple phone book.

The above picture shows a set of two contacts each of which is presented on a separate card. It appears that such a card can constitute a single row in a table:

Name Tel No.

Contacts table
Name	Tel No.
Joan	699 23 43 12
Adam	711 19 77 21
