The G Pattern Language A Framework a Method and an Environment for the Object Oriented Design of Large Distributed Software Systems with Applications to Computer Integrated Manufacturing

Three lessons have been learned by applying the Object Oriented Approach to the design of large concurrent and distributed software systems programming in the large adopt a unitary computational model to favor the use of frameworks of classes approach the design with an evolutionary development process to split in time design decisions and so cope with complexity use integrate CASE tools for the automatic transformation through the phases of the design for the automatic code generation of the implementation from speci cations and object model for documentation and common project repository This ten year long search has been motivated by the Computer Integrated Manufacturing CIM domain and has generated a computational model frameworks of reusable classes for the C language a design methodology and a development environment collectively know as G
