Database Administrators typically do the following:
• Ensure that organizational data are secure
• Back up and restore data to prevent data loss
• Identify user needs to create and administer databases
• Ensure that databases operate efficiently and without error
• Make and test modifications to database structure when needed
• Maintain databases and update permissions
• Merge old databases into new ones
Database Administrators, often called DBAs, make sure that data analysts and other users can easily use databases to find the information they need and that systems perform as they should. Some DBAs oversee the development of new databases. They have to determine the needs of the database and who will be using it. They often monitor database performance and conduct performance-tuning support.
Many databases contain personal or financial information, making security important. Database Administrators often plan security measures, making sure that data are secure from unauthorized access.
