Combined save and validation logic

Methods, systems, and computer-readable media for combined saving and validation are disclosed. A particular method includes receiving a command to save changes associated with a change set to a data storage device. Entities of the change set are validated and one or more pre-operation commands are executed on the change set. When a pre-operation command modifies one or more first entities of the change set, the first entities are revalidated. The method also includes executing a data operation based on the change set and executing one or more post-operation commands on the change set. When a post-operation command modifies one or more second entities of the change set, the second entities are re-validated.
