Basically databases are used to store information.

A primitive form of `database' is a filing cabinet.

The fundamental types of databases include,

- Relational - Data is kept in fixed tables with defined relationships

- Object Oriented - Dissimilar data can be stored in a single list (relational databases are a sort of subset of these databases)

Databases allow information stored on one computer to be shared with other computers.

Data stored in relational databases is commonly access using SQL (Structured Query Language)

Databases handle problems of,

- data locking (only allow one user to modify at once)

- data sharing (other users can view)

- searching
