摘要：
In a data dictionary directory system, the definition information to be registered in a dictionary is registered being divided into several definition units. A data base system registers the definition information and confirms the coordination of the contents of definition among the definition units. The definition information is registered without confirming the coordination. The coordination is confirmed when it becomes necessary to confirm the coordination among the definition informations registered in the dictionary.
