Abstract: A method of database changeset management for automated information enhancement and control over changesets using a computational device. The steps include: analyzing and processing a query; journaling the query into a changeset-journaling module; recording a blocking journal entry based on a blocking characteristic of the query into a journal blocker module; sending a database mutation statement to a database. Undo requests are checked against the blocking journal before execution. Further steps include: triggering an interest protocol on a match of a query with an interest set; returning a response to a query based solely on information from a changeset-journaling module; comparing an actual return from the database to an expected return and generating a difference statement therebetween; providing a collaboration module; and providing a second changeset-journal module configured to journal an alternate database state; and returning a query result based on the alternate database state.
