A computer-implemented method for managing a database space includes writing, via a processor, a purge rule to a database management system (DBMS). When the purge rule is executed by the DBMS they automatically purge data in one or more databases at regular intervals. The method includes executing, via a DBMS processor, the purge rule. The purge rule is configured to define, via the DBMS processor, a purge object having purge object attributes without user intervention, and purge, via the DBMS processor, the data based on the purge rule at intervals defined by the purge rule attributes and without user intervention.
