Research And Implementation Of Work-content-driven Engine Based On Dual-driven Workflow Pattern

Nowadays, workflow technology is one of the fastest growing new technologies in the computer field, and has become a hot topic in computer application development field in recent years. Workflow engine is the core technology of workflow management. In recent years, large foreign software companies have increased the investment of researching and developing their workflow engine products, and also have developed their own products.However, with the development of workflow technology and the deepening of practical application, more demands about workflow engine have been made. The existing workflow engine products are basically revolved around the single process-driven workflow engine which can well resolve the process-driven of process. But this workflow engine can only give limited support for task-level-driven issues, and is difficult to meet the growing business requirements of applications. At the same time, the existing workflow engine has some problems and deficiencies in the flexible workflow pattern, compatibility of secondary development system, etc. As a result, it is necessary to address these deficiencies in-depth study.On the basis of in-depth study of the workflow engine theories and technology products, combined with practical applications in recent years, this paper focuses on the research of dual-driven pattern structural system and implementation of work content engine which is based on the dual-driven pattern; addresses existing problems of the insufficient capacity of task-execution level abstraction in existing workflow engine; modeling the work-content-driven model based on the ideology of resources generalization; improves the abstraction of work-content-driven model; makes a further work to introduce and research the key design of achieving work-content-driven engine; finally, gives a in-depth description of core technologies of achieving the work-content-driven engine.
