Concept of software processes is considered as a key technology for scientific and rational way of creating complex and advanced softwares systems.
The purpose of the project was to exploit the technologies and the environmental support for the software processes. Both Japanese and American Researchers have studied process programming languages and formal method for describing software object bases, and have came to some useful insights as follows.
For the process programming language, American researchers have developed a procedural language based on ADA, while Japanese researchers have used HFSP, PDL and Prolog. It was found out that the American approach has more descriptive power than the Japanese approaches, while Japanese approaches are more readable than the american approach. Speaking of the programming environment, American researchers have demonstrated their environment which is well implemented, especially on the user interface issues and degree of integration. For the object bases, American researchers used the programmable relational database, which is a relational database extended with declarative conditions which must be satisfied during database operations. On the other hand, Japanese researchers have proposed a software objectbase model based on the attribute grammar formalisms, which uses incremental computation f attribute values to maintain relations and conditions among software objects.
