A Model Based Approach to Enterprise Wide Information Support
P. E. Clements, Ian A. Coutts, John Edwards · 1997
This paper demonstrates an ability to bridge between conceptual information models representing a manufacturing enterprise and the realisation of these models within a relational database management system. The information architecture defined within the paper is based on the ANSI Three-Schema approach to database management which splits the data management issues into three separate parts and thereby realises important benefits in complex systems where information sharing needs change frequently. The tools created to implement this information architecture support the following lifecycle phases of requirements definition, detailed design, and system execution and maintenance. This paper concentrates on the implementation and system execution issues. The approach provides direct support of system change by providing structured diagramming and mapping tools which semi-automate information requirements definition (and ongoing change in requirements), and model driven systems implementation tools which facilitate the construction and runtime management of the required system using the services of an integration infrastructure.
