Applicable Research Of J2EE Based Cooperative Authoring System

Computer Supported Cooperative Work (CSCW) means that a group of users in different places communicate and cooperate to complete one single task under the support of computer network. The system involves the interaction of computer, the distribution of network and the integration of multimedia. In the system, people of different profession can work cooperatively. Its wide application has already made definite and profound effect on people's work and life.Nowadays, with the further research of CSCW, CSCW concept based Cooperative Authoring System has become an important and independent research subject. Cooperative Authoring means that a certain group of people cooperate to complete an authoring task, and it bases on certain cooperative mechanism. We emphasize on the process of the cooperative authoring task, and admit the importance of cooperative mechanism.This task is imbursed by Beijing Education Committee. It focuses on two aspects of Cooperative Authoring System: How to realize the reformation on technology, how to take full advantage of the new technology to adapt to developing requirements; How to make balance between generality and particularity, how to conclude an informational simulation of the real cooperative authoring task, and how to pay enough attention to the psychology of all the cooperating participants.We construct the Cooperative Authoring System on J2EE technology, upgrade the research and realization from application to platform. The system is not only to serve one single task and generate one single document, but also a cooperative basis among multiple tasks and multiple documents. We divide the real cooperative authoring task into two parts, cooperative edition authoring and cooperative conference. We offer the former operation-increment-edition-tree based cooperative authoring mechanism, and offer the latter public-and-private-area based cooperative mechanism. We also bring forward a whole new logic view of the cooperating editor.This thesis introduces the research background, summarizes J2EE related technology, designs the J2EE based Cooperative Authoring Architecture, and expatiates some key problems and techniques as well.
