An approach for tracking system changes to support data maintenance within a directory service environment. Log fields are added to a directory service database for applications that interface with a directory service environment based on predetermined fields to be tracked. The log fields are updated to register database schema fields and data associated with the applications to create a history of changes. An application's identity and data access to the directory service environment are monitored and the log fields are updated to create a history of usage. The directory service database history of usage and changes are periodically analyzed to determine applications relationship dependencies and usage information. Associated maintenance actions are identified by detecting conditions in the directory service environment, based on predetermined maintenance criteria and maintenance is performed.
