About the test

The Database Administration online test assesses knowledge of database management systems and SQL skills through a series of live coding tasks that require writing SQL queries. 

The assessment includes work-sample tasks such as:

  • Monitoring database performance, troubleshooting issues, recovering data from a backup, and other database administration tasks.
  • Writing queries and subqueries that join, group, filter, and aggregate data.
  • Creating new database tables with proper table schema and constraints.

A good database admin, back-end developer, or SQL developer all need a solid understanding of Database Administration procedures to effectively store and organize data, as well as use SQL to interface with and access a database efficiently.

What others say

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
