Design of databases

After taking into account the client’s specific requirements, particularly concerning the size of the database, the database administrator sets up standards and good practices for the development teams.
In collaboration with the various project stakeholders, he/she defines the database implementation choices. Following this, the administrator defines the database parameters, the security rules, models, and designs the tables and keys.

Administration and maintenance

Once the database has been set up, the administrator must implement the data on the technical support. In terms of administration, this means guaranteeing the availability and quality of the data, administering access authorizations, and dealing with security issues. On the other hand, in terms of maintenance, this means ensuring that the data is updated, backed up, and upgraded. It is also the Database Administrator’s responsibility to guarantee the recovery of data and the restoration of conditions following an incident, as well as the correction of any bugs.

Technological monitoring and control of the database

The role of this professional is also to monitor the evolution of database versions and to carry out tests and validation of their management. He/she will also have to anticipate technical developments with a daily technology watch.

Technical skills

The Database Administrator is familiar with the main software (Oracle, MySQL, SyBase, SQL Server, etc.), the SQL query language, and security issues. Knowledge of Shell scripts under UNIX, Windows or MVS as well as knowledge of technical English is also essential.

Understanding the environment

For this professional, an understanding of the environment, its development, and its operation is essential. Good knowledge of the activities and of the client enables him/her to anticipate the latter’s needs and also to intervene more effectively when necessary.

Reactive and methodical

Since the administrator evolves on different supports: mobile databases, shared databases or datawarehouses, the functions of network architect and database administrator are often confused.

The administrator is a real link between the project managers and engineers and the users of the database in order to better define the needs of each person and the company.
The system administrator is required to work on call. Indeed, the systems operate 24 hours a day and many operations require action outside office hours.
