Who is a  database administrator

A database administrator (DBA) ensures that databases run efficiently and securely. The DBA manages, secures, and maintains data in data systems so that users of the data can perform business-related analysis using the data. DBAs are also responsible for data storage, organization, display, utilization, and analysis from a technological standpoint. An example would be that they create and organize systems to store different types of data such as financial information or shipping records. Their role is to ensure that users can access this information when needed.

The goal of a DBA is to provide a seamless flow of information through the company. They have to look at backend data structure as well as the front-end accessibility for end users. They also have to maintain adherence to a data management policy and ensure that the equipment is functional.
