A process-centered software engineering environment with network centric computing

Abstract

A good Process-centered Software Engineering Environment, PSEE, helps the project teams develop software. To support concurrent teamwork, a distributed PSEE supports the interaction and cooperation of project members. Recently, the Internet and Web technologies bring up a new concept called Network Centric Computing, NCC. The NCC provides a standard interface for accessing data to improve the extensibility of applications. In this paper, we present the design and implementation of a distributed PSEE with NCC. The architecture of our PSEE are divided into three layers: kernel, intermediate, and user-interface layers. These layers contain the web server, process server, and object server which communicate with each other though a Stateless Access Protocol, SAP. These servers are in charge of process modeling and execution, while web browser is in charge of user interface such as an agenda. This paper also presents the activities of process enactment within a project. Besides, we make a comparison between our PSEE with NCC model and prior PSEE with client-server model.
