A Database Administrator is an IT specialist responsible for the performance, integrity and security of a database. They will also be involved in the planning and development of the database as well as troubleshooting any issues on behalf of the users.
A Database Administrator makes sure that databases have the following qualities:
- 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 (all data is retrievable in an emergency).
Database administration roles vary depending on the type of database, the processes they administer and the capabilities of the database management system in use. The level of responsibility will determine the tasks carried out. Some work may be pure maintenance while other roles will involve you specialising in database development.
Because of the increasing levels of hacking and the sensitive nature of data stored, security and disaster recovery have become increasingly important aspects of the work.
