SQL refers to Structured Query Language, a kind of language used to access, update and manipulate database. In SQL, ROLLBACK is a command that causes all data changes since the last START TRANSACTION or BEGIN to be discarded by the relational database management systems (RDBMS), so that the state of the data is "rolled back" to the way it was before those changes were made.
lakeFS is a data versioning engine that manages data in a way similar to code. By using operations such as branching, committing, merging, and reverting, which resemble those found in Git, it facilitates the handling of data and its corresponding schema throughout the entire data life cycle.
A commit is an act of committing. The record of commits is called the commit log. In terms of transactions, the opposite of commit is to discard the tentative changes of a transaction, a rollback. The transaction, commit and rollback concepts are key to the ACID property of databases. [1]
Unlike commits in data management, commits in version control systems are kept in the repository indefinitely. Thus, when other users do an update or a checkout from the repository, they will receive the latest committed version, unless they specify that they wish to retrieve a previous version of the source code in the repository.

For systems without a commit/rollback mechanism available, one can undo a failed transaction with a compensating transaction, which will bring the system back to its initial state. Typically, this is only a workaround which has to be implemented manually and cannot guarantee that the system always ends in a consistent state.
"Branch has provided Walmart and their driver partners valuable services allowing quick and easy access to funds via their business accounts — a key fact the bureau's press release omits," it said.
To see the changes the rollback button will revert, view the specific diff that compares the last version from the last editor with the last version from the previous editor. The rollback link looks similar to this: [rollback: # edits] Rollback works much more quickly than undo, since it:
