Database administrators are responsible for the overall support, maintenance, design and troubleshooting of data systems. The past several years have seen a change in the way databases are designed. Big data databases have different architecture than relational databases. For administrators who have an understanding of a wide range of platforms, database administration is a promising career with great income potential.

Job Description: What Does a Database Administrator Do?

Database administrators ensure the stability of data systems across a company network. This can be a database as small as a small ecommerce site or clusters of databases across several data centers. Database administrators help design tables and review stored procedures and SQL code promoted by developers. They organize the data and maintain database security against cyber threats. They are a part of disaster recovery plans and participate in disaster recovery practices. Database administrators are also responsible for the performance of the data, so the databases are not the bottleneck for application speed.

Database Administrator Job Responsibilities and Duties

DBA responsibilities depend on the size of the company and the number of databases involved. Large enterprise databases need more maintenance and support than a single database that supports only a small application. Some database administrators are assigned tasks that involve developer with application developers.

Job responsibilities include:

  • Monitor database security and user authorization
  • Monitor performance for any bottlenecks including applications and hardware
  • Design new database servers including reports servers
  • Create table indexes to improve performance
  • Review developer code for views, stored procedures and functions
  • Add hardware to database servers when needed
  • Install new software and updates related to the database application
  • Write documentation and provide database policies
  • Design a disaster recovery plan in case of emergencies
  • Restore databases, data and tables when bugs or disaster occurs

Most database administration positions require experience. Database applications are the foundation of revenue and customer data for the enterprise. It requires a firm understanding of data and how databases work. Database administrators usually work in similar jobs and then elevate to other positions that have more responsibility. Because databases are critical to the enterprise, database administrators can gain experience by working in other networking positions that give them hands-on experience without the responsibility.
