# Version Control Features

Unlike other relational databases, Dolt has multiple branches and stores all data in a commit graph, like git. This makes it possible to efficiently diff any two commits, as well as merge one branch into another. All the git-like version control functionality available on the Dolt CLI is available in the SQL server as well, exposed as system tables, system variables, functions, and stored procedures.

## Version control overview

* [Using Branches](/sql-reference/version-control/branches.md) explains how to work with different branches in a running server.
* [Merges](/sql-reference/version-control/merges.md) explains how to merge branches into one another and resolve merge conflicts using SQL.
* [Querying History](/sql-reference/version-control/querying-history.md) describes how to query past revisions or different branches of a database.
* [Using Remotes](/sql-reference/version-control/remotes.md) describes how to use remotes to coordinate between Dolt clones.
* [Stored procedures](/sql-reference/version-control/dolt-sql-procedures.md) documents all the stored procedures that implement version control operations such as `DOLT_COMMIT`, `DOLT_CHECKOUT`, `DOLT_MERGE`, etc.
* [Functions](/sql-reference/version-control/dolt-sql-functions.md) documents Dolt-provided functions that aren't part of standard MySQL, including table functions that produce diffs of any table at two points in its history.
* [System tables](/sql-reference/version-control/dolt-system-tables.md) describes the system tables that provide read access to version control information, such as branches, commit log, diffs, and conflicts.
* [System variables](/sql-reference/version-control/dolt-sysvars.md) documents all the Dolt-provided system variables that expose and control various aspects of Dolt's behavior.
* [Saved Queries](/sql-reference/version-control/saved-queries.md) documents a Dolt feature to save queries for later execution.
