Role-based decomposition for improving concurrency in distributed object-oriented software development environments

This paper presents a role-based decomposition model for improving concurrency in distributed object-oriented software development environments. In software development process, the target software system consists of a large number of components closely related with one another. This results in potential operation conflicts in cooperative works among the project members. This problem can be much reduced by decomposing the target software system into the relatively independent components. Our system incorporates hierarchical role-based decomposition model to reduce operation conflicts frequently occur in synchronous/asynchronous collaboration. The decomposed components are also used as basic units of the role-based access control. Once the target software system is properly decomposed according to this model, its subsystems can migrate to the other sites, and thus, the components can be evenly distributed over networked computers.
