On a Cataloguing of Data Source Types, Conceptual Form Generation Patterns, and Conceptual Form Templates

Abstract

Conceptual Form model, originated by Nakanishi in 1998, is a conceptual abstraction of external schema. Conceptual Form is a unit of logical data presentation with no constraints in implementation technique.

Conceptual Form Formula is an algebraic representation of the Conceptual Form, which is determined by the logical data structure of the target data source and its selected entity access path. This formula enables us to categorize a large number of actual screen/report forms into a manageable number of catalogued patterns.

This paper explains a catalogued list of extracted 50 Data Source Types, 435 Conceptual Form generation patterns, and 77 Conceptual Form Templates.
