To obtain information having a relation, it is required for an application program to execute retrieval processing in which the program first acquires key information supervising relations between tables to sequentially trace the relations to finally obtain the target information. Since it is required for the program to execute as many access operations as there are hierarchic level of relations, the access efficiency is lowered. By establishing a correspondence between first relating information representing relations between a first table and a second table and second relating information, path information representing hierarchic structure of data between a plurality of tables is stored in a storage. Various processings are executed by use of the path information.

Information management system and method

The service function and information design process is automated in order to shorten the design process period. The same process is based upon the relationships between activities and the information that the activities provide and consume. The relationships are maintained in a predetermined format and are updated by any changes that are affecting the relationships. In addition, the activities are further defined by detailed activities.
