Consistency and Automation in Multi-User Rule-Based Development Environments

Barghouti, Naser S.; Kaiser, Gail E.

We investigate the scaling up of a class of single-user software development environments, which we call rule-based development environments (RBDEs), to support multiple developers cooperating together on a project. RBDEs model the software development process in terms of rules that encapsulate activities, and execute forward and backward chaining on the rules to provide assistance in carrying out the development process. There is a spectrum of assistance models, ranging from pure automation to strict consistency preservation. We describe three problems whose solutions are dependent on the choice of assistance model: (1) multiple views; (2) evolution; and (3) concurrency control. We discuss how the two extremes of the spectrum restrict the possible approaches to multiple views and evolution. In order to explore different aspects of the concurrency control problem across multiple points on the spectrum of RBDEs, we develop a maximalist assistance model and propose an approach to synchronization of cooperating developers within the context of this model.
