1. An automatic database command method, comprising: obtaining a plurality of relevant database log entries, the relevant database log entries being directed to database catalog entities; determining a first portion of the plurality of relevant database log entries are part of a common unit of recovery, the first portion including a plurality of database log entries; assigning the first portion of database log entries to a particular Data Definition Language (DDL) command object based on analysis of attributes of a first entry in the first portion of the database log entries, the particular DDL command object including a timestamp, an action, a target, and data from each of the first portion of database log entries; determining a DDL command object break when an action or target of a next database log entry in the first portion is inconsistent with the particular DDL command object; storing the particular DDL command object in a memory in response to determining the DDL command object break; receiving an indication of an operation type subsequent to the storing, the operation type being an UNDO or a MIGRATE operation type; ordering the entries in the particular DDL command object in an order based on the type of operation, the targets, and the actions; and generating at least one database command based on the operation type, the action, target, and data in each of the ordered entries in the particular DDL command object.
