A method and mechanism for dependency tracking in a database system is disclosed. According to an embodiment, dependency tracking for a referentially constrained object is performed by tracking change or commit time values for key ranges as well as change or commit time values at various granularities in the database. The combination of various sets of change or commit values are employed to determine a single value representing all prior transactions or changes that an operation is dependent upon.
