Application Of Workflow Technology In Defect Trace Systems

The scale of the software development enlarges gradually, the bugs appearing in the development process is more and more. Therefore, carried on to follow the defect management, insure each discovered defect can be dealt with in time is the work of an important content. In order to solve the problem, software companies need Defect Trace System (DTS).In defect tracing field, it needs cooperation working. So we use technology of workflow. A Workflow is a collection of Steps and data that define the paths that can be taken to complete a task. Workflows may contain activities such as displaying content to users, collecting information from users or computer systems, performing calculations, and sending messages to external computer systems.This paper works over on the future of defect trace and technology of workflow, it adopts a method extending Finite State Machine (FSM) to describe workflow process model. After deep research on the logic of the workflow model, produces the design and the realization plan of the workflow engine, which realizes the definition and control of the workflow. At last this paper gives a Defect Trace System design scheme and points out system weakness and essential in later work.
