Data management system

摘要

A data management system enables a user to make flexibly correspond relationships between data, which is stored in an existing database and a data file. Further, a program for processing the data file in accordance with the system is also disclosed. A user register includes a relationship between a data unit stored in a existing database (11), a data file and a program for processing the data file. The data file and program both exist outside of the first database (11). After the retrieval of the data unit from the existing database (11), if the corresponding relationship for the retrieved data unit is registered, a program related to the data unit is activated for processing the related data file in response to the user's instruction (12).
