Disclosed can improve rights list management as well as performance of systems utilizing an access control list. A database server having a transitive closure management module may receive an identification of an entity defined in a database storing a cached transitive closure. The transitive closure management module may incrementally update the cached transitive closure stored in the database by generating a new transitive closure for the entity and determining a delete transitive closure record. The delete transitive closure record may be determined by analyzing the cached transitive closure and the new transitive closure, determining a first transitive closure path for the entity that is not specified in the new transitive closure and that is specified in the cached transitive closure, and selecting as the delete transitive closure record a record specifying the first transitive closure path. The delete transitive closure record can then be deleted from the cached transitive disclosure.
