Commit command can be used in Database Management System and Git also. In the question it is not mentioned.

commit in relation with DBMS

A transaction is a unit of work carried out against a database. Transactions are sequences of work accomplished in a logical order, in a individual way by a user or automatically by some sort of a database program.

A transaction is the sequence of one or more changes to the database. Suppose, if you are creating a record or updating a record or deleting a record from the table, then you are performing a transaction on that table. Transactions are controlled to ensure the data integrity and to handle database errors.

The COMMIT command is used to control transactions.

COMMIT – It is used to save the changes to the database.

The COMMIT command is the transactional command used to save changes invoked by a transaction to the database. The COMMIT command saves all the transactions to the database since the last COMMIT or ROLLBACK command.

The syntax for the COMMIT command is as follows.

COMMIT;

commit in relation with Git

Version control software is an important part of software developer practices.

Git is widely used version control system in the world. It is a distributed and actively maintained open source project.

The commit command is used to save changes to a local repository after staging in Git. Before you can save changes in Git, you have to tell Git which changes you want to save as you might done many edits. It is done by adding a commit message to discover the changes.

A good Git commit message is the best way to communicate context about a change to other developers working on that project, and for yourself also.

Commit messages can adequately communicate information about why a change was made, and understanding that makes development and collaboration more efficient.

Commit Options

• -m

This option sets the commit's message.

git commit -m "Setup multiple roles for netlify-cms git gateway"

• -a

This option rewrites the last commit with any staged changes or a new commit message. It should only be performed on commits that have not been pushed to a remote repository yet.

git commit -a "Setup multiple roles for netlify-cms git gateway"

• --amend

This option rewrites the very last commit with any currently staged changes or a new commit message. It should only be performed on commits that have not been pushed to a remote repository yet

Conventions to write a git commit message :

1. Limit the subject line to 50 characters.
2. Capitalize only the first letter in the subject line.
3. Wrap the body at 72 characters.
4. Use the imperative mood.
5. Describe what was done and why, but not how it is done.
6. Don't put a period at the end of the subject line.
7. Insert a blank line between the subject line and the body.

Hence is important when using the commit command to include a descriptive message
