        "Core technologies for system renovation"


Renovation of business-critical software is becoming increasingly
important. We identify fundamental notions and techniques to aid in system
renovation and sketch some basic techniques: generic language technology to
build analysis tools, a knowledge retrieval system to aid in program
understanding, and a coordination architecture that is useful to
restructure monolithic systems thus enabling their renovation. We argue
that these techniques are not only essential for the renovation of old
software but that they can also play an important role during the
development and maintenance of new software systems.
