Personal database - The personal databases are maintained, generally, on personal computers. They contain information that is meant for use only among a limited number of users, generally working in the same department.

Distributed database - These databases have contributions from the common databases as well as the data captured from the local operations.


Fact

A database management system (DBMS) is a computer software application that interacts with end users, other applications, and the database itself to capture and analyze data. A general purpose DBMS allows the definition, creation, querying, update, and administration of databases.


Fact

Your responsibility as a database administrator (DBA) will be the performance, integrity, and security of a database. You’ll be involved in the planning and development of the database, as well as in troubleshooting any issues on behalf of the users.

You’ll ensure that:

- data remains consistent across the database;

- data is clearly defined;

- users access data concurrently, in a form that suits their needs;

- there is provision for data security and recovery control (ensuring all data is retrievable in an emergency).
