This page includes introductory material for new database reviewers.
If you are interested in getting an application update reviewed,
check the [database review guidelines](../database_review.md).
## Scope of work done by a database reviewer
Database reviewers are domain experts who have substantial experience with databases,
`SQL`, and query performance optimization.
A database review is required whenever an application update [touches the database](../database_review.md#general-process).
The database reviewer is tasked with reviewing the database specific updates and
making sure that any queries or modifications will perform without issues
at the scale of GitLab.com.
For more information on the database review process, check the [database review guidelines](../database_review.md).
