A method, system and article of manufacture for managing modifications to at least one of a plurality of interdependent data objects. The method comprises receiving a request for modification of a given data object having at least one dependent data object and accessing a directory of dependencies containing records for each of the interdependent data objects including the at least one dependent data object. Each record describes an interdependency between at least two of the interdependent data objects. A record for the at least one dependent data object describes an interdependency between the given data object and the at least one dependent data object. Using the accessed directory of dependencies, the interdependency between the given data object and the at least one dependent data object is identified. On the basis that the identified interdependency presents a possible undesired consequence if the requested modification is performed, a predefined action is performed.
