Database Administrator (DBA)

A database administrator (DBA) is an IT professional who ensures that the software used to manage a database is properly maintained to allow rapid access when needed. Because constant access, searches, traffic are likely to have a damaging effect on any company database, the DBA works to maintain the efficiency of the servers. He or she also will typically work to ensure data security, coordinating with an IT security professional or team in larger companies to help maintain the integrity of sensitive business data.One of the main jobs of a database administrator is to keep a company's information accessible in an efficient manner. Many companies require that data be available via cloud servers so that it may be accessed at any time. In reality, a DBA houses only a small percentage of data in a cloud setting, due to the expense and security issues created when doing so. However, the DBA ensures that cloud access to data can be accomplished quickly and efficiently.To work as a database administrator, a person typically will need a bachelor's degree in computer science, an associate's degree in database administration, or a similar degree. Many companies will also require a DBA candidate to have a background in IT work on database administration teams. Typically, an administrator works regular business hours during the week, but many companies require a DBA to be available on call at all times, in case of a system emergency.
