Methods and tool support for the evolution and re engineering of legacy systems

Cel



The principal business objectives of the industrial partners in the RENAISSANCE project are to improve their capability of offering profitable services in the area of system evolution, and to increase their return on investment in their software assets. We believe that these business objectives can be met by developing a more methodical approach to evolution and re-engineering which is consistent with current development and maintenance practices used in industry.

The main objective of the RENAISSANCE project is therefore to develop a systematic method for system evolution and re-engineering which is geared to the requirements of the commercial systems domain.

The RENAISSANCE method will take into account technology changes in this domain which have led to customer pressure to migrate applications from centralised mainframes to object-based, distributed client-server systems. It will include support for the specific requirements of 3GL and 4GL system evolution. The key sub-objectives of the project are therefore:

- To provide techniques for modelling the principal structures of 3GL and 4GL business applications and to give advice on the use of architectural modelling as a basis for system understanding, re-engineering and distribution of these systems.
- To provide techniques and technologies for converting centralised legacy systems and associated data to distributed client-server system architectures.
- To provide advice to managers responsible for planning the evolution process on evolution strategies, organisational factors which must be taken into account in the planning process (e.g. process changes, training, etc.) and the risks and economics of applying these strategies in the evolution process.

The principal result of the project will be a RENAISSANCE method handbook which describes a generic method for software evolution with variants reflecting the specific requirements of 3GL and 4GL evolution. The method handbook will be widely disseminated through a commercial publisher. The handbook will include information about evolution processes, system models and documentation for evolution, and rules and guidance for applying the method.

This handbook will be supported by a set of more detailed RENAISSANCE consultancy reports and associated training materials which may be used to develop internal and external consultancy services in the areas of system maintenance and evolution.

These reports will cover system modelling for evolution, migrating to distributed client-server systems and evolution planning.
