This paper introduces a language concept, guarding processes, as a method of structuring concurrent programs in distributed computing systems without a common memory. In the concept a program consists of modules each of which defines objects and servers with multi-processes The concept is based on two types of path expression. One type is used to achieve synchronization, mutual exclusion, and autonomous...
A major issue in software engineering is the mastery of sofware design. The increasing distributed programming facilities open lots of new possibilities but make the task of designers more complex. Our work is to contribute to a rational design of real-sized distributable applications. We propose an approach based on the VDM formal method as support for the design phase and based on the Conic distributed...
Although numerous distributed programming facilities have been developed, the lack of methodologics to support the design of distributed applications makes the task of designers very difficult. The aim of our work is to contribute to the design of complete distributed applications, stressing first and foremost the quality of the final systems. To reach this goal we propose a software development environment...
