Problems solved by technology

However, the currently recognized status of process activities only includes: initialization, preparation, running, completed, and throwing an exception, making it impossible for process managers to quickly make decisions about process operations based on the only status information
Moreover, for each Web service combined with BPEL, since it is a stateless entity based on the HTTP protocol, it cannot satisfy the maintenance, access and management of the interoperable state between the client and the server in practice.

Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing.

[0034] Such as Figure 1~3 As shown, a state-driven executable business process execution method includes the following steps:

[0035] A. Use the Web Services Resource Framework platform (WSRF platform, Web Services ResourceFramework platform) to manage the attribute parameters corresponding to the Web service status, and interact with the business process status, so that the business process can dynamically configure the process behavior and decide the direction of the process according to the current status information;

[0036] B. According to the above state information, UML finite state machine is used to model the business process, so that the above state information can be expressed formally, and the separation mechanism of business logic and process logic is established according to the state information.

[0037] Described step A comprises:

[0038] Management o...

Abstract

The invention relates to a state-driven executable service flow execution method, which comprises the following steps: A, managing an attribute parameter corresponding to a Web service state by using a Web server resource frame work platform (WSRF platform), and interacting with the service flow state to make the service flow configure flow behaviors dynamically according to current state information and determine the direction of the flow; and B, according to the state information, using a united modeling language (UML) finite state machine to model the service flow to enable the service flow to express the state information in a formalized manner and establishing a service logic and flow logic separation mechanism. Compared with the prior art, the invention provides a state-driven executable service flow scheme, which enables enterprises to grasp the operation conditions of a current flow in time so as to make a real-time decision to reduce enterprise loss and improve enterprise efficiency.

Description

technical field [0001] The invention relates to the field of business process control, in particular to a state-driven executable business process execution method. Background technique [0002] A business process can be defined as a set of interrelated tasks connected by activities with various functions. How to combine distributed Web services to realize business processes is of great significance for enterprises to realize globalization and virtualization. Traditional business process management uses BPEL (Business Process Execution Language, Business Process Execution Language) to combine the WEB services provided by each enterprise to achieve cross-enterprise collaboration. [0003] A process state is a process execution condition at a specific process execution point. If the state is explicitly determined in a process model, it is possible to quickly monitor the execution of the process runtime based on the state information. Moreover, process states can effectively...
