Abstract: Systems and methods are disclosed for managing updates to time-constrained data contained in a database. The disclosed systems and methods may include applying a time constraint to govern permissible relationships between a set of related records contained in a database. An application may comprise a client interface allowing a client to request that multiple updates be performed on a set of related time-constrained records. The system may determine whether the multiple updates are consistent with the applicable time constraint. The multiple updates deemed consistent may be implemented on the set of records. Systems and methods consistent with the principles of the present invention may implement multiple updates without requiring pre-ordering of submitted multiple updates, wherein the number of records existing after implementing the consistent multiple updates may be consistent with the number of records existing before implementation of the multiple updates.
