The architecture of the SPADE-1 Process-Centered SEE

SPADE is a project carried out at CEFRIEL and Politecnico di Milano. It aims at defining a process modeling language (called SLANG) and a Process-centered Software Engineering Environment (PSEE) based on this language. PSEEs support software activities through the execution of the model of the software process. Such a model integrates the description of human activities and of the interaction between humans and software development tools. Moreover, PSEEs must provide the means to manage and persistently store the artifacts developed within the process. SPADE-1 is an implementation of the SPADE concept. In particular, it includes a SLANG interpreter and facilities to store process artifacts in an object-oriented database (O2), and to interface the process interpreter with an integrated tool environment (DEC FUSE). This paper summarizes the architectural requirements derived from SPADE and provides a description of the SPADE-1 prototype
