If you mean updates to the schema then some sort of migration system surely exists for your framework of choice, such as in Rails and Laravel too I think.

If you mean one-off changes to existing data what has served me well so far is implementing an audit log from the start coupled with making sure that records are fudgeable by a select few admins.

This means that a few people can make changes to nearly everything from the interface rather than having to log into the DB directly. At the same time there is a record of changes done and the ability to comment on and revert them.
