Study Of Common Integrated Framework Supporting Group Work

Group work includes individual work and group cooperative work. To make computer more important in human activities, it is not enough to only support individual work. People began to study how to support cooperative human activities, so as to improve the efficiency and quality of group work, through computer. CSCW (computer supported cooperative work) is one of the research hotspots currently.The application domain of CSCW is very broad. A good integrated development environment can considerably shorten the exploitation cycle and decrease the development costs, which needs meet the requirements of openness, flexibility, reusability and facility.Many researches indicate that the next-generation CSCW system will be constructed based on component technology. The current component standards like CORBA and DCOM, however, are proposed to support the distributed computing, which can not satisfy the CSCW requirements directly. Therefore, extension of current component standards is necessary.This dissertation addresses the key techniques of constructing common integrated framework based on component technology, which can support group work all around:1. To help framework reach the demands of openness, facility, transparent integration of various tools, a set of integrating techniques to realize common integrated interface of tools is brought forward, which include: For integrating tools in source-code format, we provide the two-level programming interface; For integrating single-user tools in object-code format, we propose the OLE and message hook hybrid black-box integrating mechanism; For integrating multi-user (network program) tools, we provide the communication agent.
