SQL Server is a relational database management system (RDBMS) from Microsoft designed for the enterprise environment. SQL Server adds a number of features to standard SQL, including transaction control, exception and error handling, row processing, and declared variables. Being effective as a SQL Server Database Administrator (DBA) therefore requires a thorough understanding of SQL Server’s advanced capabilities and a corresponding level of technical acumen and sophistication.

Depending on the specifics of the position and the organizational structure, a SQL Server DBA can be expected to perform a wide variety of mission-critical functions for the company. Ideally, s/he will have an appreciation of – and long-term perspective on – how best to leverage database technology to address the business opportunities and challenges facing the company. The DBA must work with application development and IT operations to help achieve a state-of-the-art environment that meets current and future business objectives, while at the same time ensuring that the company’s production databases offer the highest reliability and performance possible.

This job description template provides a general overview of the types of skills and capabilities that an experienced SQL Server DBA should possess. The specifics will likely need to be adjusted based on the specifics of your environment and organization, as well as the experience level of the candidate you are looking for.
