This project addresses the problem of developing reliable, flexible and maintainable business information systems. It builds on the results of an earlier ESPRIT project (RUBRIC) which developed a paradigm for specifying a business system by a set of rules reflecting the business environment. The goal of TEMPORA is to apply and further extend this paradigm in two directions.
First the paradigm is integrated with a state-of-the-art RDBMS for exploitation in an industrial environment. This is supported by the development of tools for supporting the design discipline of the rule-based paradigm and the delivery of application software.
Second, the rule-based paradigm is extended to allow the explicit modelling of dynamic and temporal information. This is achieved by using a temporal logic-like language for expressing the rules. This extension is integrated into the design discipline and its exploitation in the run-time environment.
The project will be completed at the end of 1993. After having defined the architecture and the operating principles of the TEMPORA system, the project has implemented the tools necessary to support both the modeling phase and the run-time exploitation phase, and has successfully integrated them in a running demonstrator, which is being tested on a full scale case study. Remaining work concerns the final testing and documentation of the demonstrator.
The TEMPORA technology offers the following advantages:
The results at the end of 1993 will include the TEMPORA methodology, and the various tools which comprise the TEMPORA system: conceptual level capture tools, schema generators and rule compilers which generate the application software, a run-time system including a rule manager operating on top of a relational database and able to manage temporal rules.
Industrial exploitation of the system by the consortium will be based on the exploitation of specific modules, such as the rule manager and the interactive graphical modeling tools, and on the exploitation of the methodology itself. The technology has already been applied successfully in commercial software development project during the lifetime of TEMPORA itself.
