Alignment method for data in user data files

摘要

The method involves holding data in at least two user data files (D1,D2), personnel user file (D1) and telephone user file (D2). The two data files describe a number of objects using parameters. Each data file is managed by a user control (P1,P2) which has no direct access to the other user data file. Both user data files (D1,D2) concern the same objects and use shared parameters. A comparison control (M) controls the management of the data in a directory data file (D4) which holds parameters for shared objects with both user data files have in common and which can accept different values. Each user data file and the directory data file contain a key parameter (UID,TX3) identifying the object.
