Over several decades we are using the databases and the related areas in various fields in one form or the other. We have seen several evolutions in the growth of the field of database. Today we have so many versions, so many vendors and so many open sources in databases. Most of the businesses cannot happen without databases. Though we have so many variations in the way the databases work and related technologies, it still heavily needs experts in the field of database, especially the conventional databases like relational, object, parallel and distributed database.
We can relate the following list of jobs directly with Databases;
Database administrator is a professional responsible for installing, configuring, monitoring, securing and maintaining a database or set of databases of an organization. Smaller organizations may have one DBA, and larger organizations may have more number of DBAs according to the size and the number of subsystems to be maintained, etc.
Database developer is a professional who develops anomaly free and most optimized database for the organization.
Data analyst is a professional who performs the analysis, running various mathematical calculations to determine how the data samples might best be applied to profit the business.

Also, he is responsible for leading the strategic design and maintenance of business intelligence applications.

Database programmer is a professional who writes database codes like Triggers, Procedures, Functions, etc., performs quality checks and designs the protocols of enterprise access to a database or data warehouse environment. In the emerged fields like data warehousing and the business intelligence, database programmers may work with Online Transaction Processing (OLTP) systems in the case of traditional RDBMSs, or Online Analytical Processing (OLAP) systems for analyzing the data in the case of enterprise data warehouse systems.
There are many more jobs that are directly related to the field of databases. As a whole, we can say that the job is named based on the overall or specific requirements. That is, a small company with small sized database may employ one DBA, at the same time a large organization may need more people to work on various aspects of data and database.
