What Does a Database Administrator Do?
Companies that want to better understand their customers use database science to do it. A database administrator (DBA) is the magician who makes that possible.
A database administrator uses specialized software to develop, store and organize a company's data. The data often includes sensitive information, such as confidential financial numbers or proprietary information. A database administrator, also called a database manager, makes sure the data is available to approved users yet secure from unauthorized access or data corruption.
A DBA typically works with an organization’s management team to understand the company’s data needs and what the database will do. This in-demand role is needed in any work setting that requires a large, secure database, but a DBA is standard in the banking, insurance, retail and healthcare industries.
Many database administrators handle a wide variety of duties, while others specialize. For example, database architects design and create new databases. System DBAs focus on the physical elements of a database, installing upgrades and making sure there are no bugs. Application DBAs focus on a database used for a singular purpose and make sure that all database elements and applications work properly.
