This book delivers the latest developments in object technology and their impact in computing systems re-engineering. Object-Oriented programming is here shown to pro support for constructing large scale systems, cheaply built and with reusable components, adaptable to changing requirements, efficient and cost effective techniques. Internationally recognized authorities from Finland, France, Germany, Italy, Poland. Spain, UK and the USA here record their research and development work on the industrial techniques and structured Object-Oriented methodologies in forward and reverse engineering of computing systems. This book takes stock of progress of that work showing its promise and feasibility, and how its structured technology can overcome the limitations of forward engineering methods used in industry. Forward methods are focused in the domain of reverse engineering to implement a high level of specification for existing software. The book contains the selected, quintessential content of the first UK Colloquium on Object Technology and Systems Re-Engineering held at Oxford University in 1998. The conference was sponsored by British Telecom Laboratories, EMSI limited, FriReme international and the OOSP Specialised Group ofΒ the British Computer Society.
