Framework for data element standardization

Dagobert Soergel


This paper describes a method for the definition of data elements in CASE (Computer-Assisted Systems/Software Engineering) systems, data element dictionaries, and data element repositories. The proposed method derives its power from its simplicity and its use of classification and knowledge representation techniques. It is based on the entity-relationship approach. A data element definition consists of a frame which gives the underlying relationship type, the focal entity type (about which the data element gives data), the related entity type (the nature ofthe data values), and a rule for determining the data value. These frames form a hierarchy which is based on a hierarchy of entity types (or ontology) and a hierarchy of relationship types.
