Patent ID: 7249134

Claim:
A method of modeling reference data in an information system (IS) based on a Unified Modeling Language (UML) model of reference data for the information system listed in deposits of application data for the information system, wherein any reference data in the information system is defined by a specialized concept inheriting characteristics of a generic concept, comprising the steps of: grouping the said concepts into categories according to logical criteria; building a categories diagram in which the said categories are grouped according to a predefined typing of categories, the said categories being related to each other by UML dependence relations, each materialized in one reference data; making groups of generic concepts in the same category consistent with deposits of application data in the IS by applying the principle according to which reference data defined by specialized concepts inheriting generic concepts in a same category and possessing an identical specialization necessarily belong to the data deposit of a unique application; defining a direction for UML dependence relations relating the said categories to each other, the said direction of UML dependence relations depending firstly on typing of categories, and secondly on the deposit of the reference data containing the relation.
