Embodiment Construction

[0048] 1. Initialize settings

[0049] Establish a distributed modeling and operating environment for workflow. The environment is shown in Figure 1, which is divided into two parts: client and server. Since we are discussing the distributed execution of workflow, Figure 1 takes two sets of workflow execution systems as examples to illustrate how the system is initialized. The invention is suitable for the situation where there are multiple sets of workflow execution systems.

[0050] The environment establishment process of a workflow execution site is as follows:

[0051] (1) Install the operating system and database software for the server. The operating system should be Windows 2000 and above in Microsoft's Windows series operating system; the database software should be relational database software that supports ODBC access interface, such as Oracle The company's Oracle, IBM's DB2, Microsoft's SQLServer, etc. To install the operating system for the client, you should use Wind...

Abstract

The invention relates to a work flow model dynamic segmentation method which supports distributed implementation, which pertains to the technical field of enterprise work flow model segmentation. The invention is characterized in that: the method is realized in each set of work flow system which is composed of a server and a client; the server is provided with a modeling module, a divided piece pool module, a divided piece management module, an activity monitoring module, an activity distribution module and a database, the client is provided with a task client module; wherein, the divided piece pool module sends the set work flow model in the modeling module to the divided piece management module, the divided pieces which are obtained by the dynamic segmentation of the model are sent to the divided piece pool module for the use by the task client module; the function of the activity distribution module is to provide actual implementation station labels for the activities, or designate the actual implementation station labels for the follow-up activities of the new divided piece after segmentation; and the activity monitoring module is used for dynamic recording of the various activities which are implemented by the actual implementation stations. The invention proposes the work flow model dynamic segmentation and implementation method, which has a broad application prospect.

Description

Technical field [0001] The dynamic segmentation method of workflow model supporting distributed execution belongs to enterprise information processing, especially in the technical field of service-oriented architecture workflow model segmentation. Background technique [0002] Service Oriented Architecture (SOA) is becoming the mainstream architecture of enterprise information systems with its business-oriented, loosely coupled, and standards-based characteristics. [0003] In the service-oriented workflow model, each activity comes from different services, and these services are physically distributed. Therefore, the use of multiple workflow machines to execute a (composite) workflow model has become an inevitable requirement for the development of workflow execution technology. This not only conforms to the characteristics of service decentralization and autonomy, but also improves the parallelism of business processes and system performance. [0004] Modeling is the primary ta...
