Architecture for Modular Type System for Information Systems Based on Relational-Applicative Technologies

Abstract

In the recent years a tendency in information systems development has manifested itself to use a (meta)data framework. While using software frameworks (user interface elements and engines, whole functional subsystems) has been common practice for decades by now, it is only relatively recently that developers began more and more often to shift away from relying on static subject domain conceptual schemes. This is in response partly to the tendency of growth of subject domain model in conceptual diversity, and partly in attempt to capture the shifting nature of subject domains. In this paper we describe an architecture and supporting data structures for a reusable engine that allows describing concepts, storing data objects with respect to the conceptual structure, and controllable modification of data and concepts.
