Abstract

A data management method and system of memo information utilizing a data base can store personal memo information at a high storage efficiency and a high retrieval efficiency without adding a retrieval key to the data base. The data management system may be constructed by connecting a work station having a file for storing memo information to an existing data base system. The system has keys for indicating records of the data base and storage addresses of the corresponding memo information as a connective index file, and refers to it to store, retrieve or delete the memo information. A plurality of memo information for the same record may be displayed on a display of the work station in a time sequence and the memo information are paged.
