Problems solved by technology

[0009] 2. Poor flexibility: Different types of workflow engines have their own independent set of workflow models, workflow definition languages ​​and API functions
[0010] 3. Operational performance issues: At present, most workflow products have a certain lack of operational response time and concurrent processing capabilities, which cannot meet the needs of enterprises to process tens of thousands of businesses per day, or even thousands of businesses per hour.
[0011] 4. Lack of flexibility: whether it is process model definition or authority role analysis, the existing workflow system shows different degrees of flexibility and poor characteristics
[0012] 5. Poor stability: In the actual application of the workflow system in the enterprise, some unconventional operations often cause process execution errors
[0013] 6. Immature implementation technology: none of the current implementation technologies used in workflow products or prototype systems can reach the level of relational database management systems
At the same time, because the workflow uses a separate database session, it often causes the key problem of data inconsistency between the workflow and the business system

Embodiment Construction

[0027] Below in conjunction with specific embodiment, further illustrate the present invention, it should be understood that following specific embodiment is only for illustrating the present invention and is not intended to limit the scope of the present invention, after reading the present invention, those skilled in the art will understand various aspects of the present invention All modifications of the valence form fall within the scope defined by the appended claims of the present application.

[0028] The invention provides a design method of a workflow engine system based on a relational database, the method comprising the following steps:

[0029] (1) Design and establish the relevant tables of the workflow engine in the database system, which are divided into configuration tables and process data tables. The configuration table decomposes each item, defines the process and the specific data item content; process Data table, which records the link process information ...

Abstract

The invention provides a design method of a relational database-based workflow engine system. The method comprises the following steps of: designing and establishing the correlation table of a workflow engine in a database system; designing and developing the operating method of the workflow engine in a database; when the workflow engine is used in a specific software application system, integrating the workflow engine with the application system; and according to the requirements of service functions, processing the flow of service logic by a corresponding method which is provided by the workflow engine in the software application system. The method is characterized by low cost, high flexibility, high processing capability and high stability.

Description

technical field [0001] The invention relates to a design method of a workflow engine system, in particular to a design method of a workflow engine system based on a relational database. Background technique [0002] Workflow is a business process that can be fully or partially automatically executed. According to a series of process rules, documents, information or tasks can be transferred and executed between different executors. The full English name of the workflow engine is: WorkFlow Engine, which refers to it as a part of the application system, and provides core solutions for each application system, such as information transmission routing, content level, etc. Program. [0003] The core part of the workflow system is the workflow engine, which is the main component that drives the process flow. It is responsible for interpreting the workflow process definition, creating and initializing process instances, controlling the flow path of the process, recording the runnin...
