Deciding how and where this information is stored is the domain of the database designer. Working with a system architect and a requirements analyst, the database designer ensures that all necessary data has a place to be stored. At the same time, the speed at which the data can be stored and retrieved are taken in to account so that user's are not left waiting for unreasonable amounts of time. Sometimes database designers take on database related activities such as arranging for backups, creating ad-hoc reports, and server tuning. However, these other tasks are often part of a Database Administrator's (DBA) job. Related Terms. 1  Database Administrator (DBA). 2  Data Architect. 3  Data Modeler.
