Abstract

The invention provides a method and system for processing workflow. The method and system for processing workflow can avoid a single-point problem in a distribution system, and improve reliability of task execution. The method for processing workflow comprises that a tree structure execution plan converted into by workflow which comprises a plurality of task nodes is saved, and in the execution plan, a task node with a plurality of father nodes appears repeatedly in a branch which the father node exists in, and for the task nodes which appear repeatedly, the task nodes with child nodes are used as execution nodes of the task nodes, and the other task nodes are used as non-execution nodes of the task nodes; the execution plan is traversed, and when a task node which the task is not executed at is traversed, the task node is occupied; all father nodes of the task node are confirmed to be executed, and then the execution node of the task node is executed.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for processing workflow. Background technique [0002] Workflow is the automation of part or the whole of a business process in a computer application environment. It mainly solves the process of automatically transferring documents, information or tasks among multiple participants according to certain predefined rules. to achieve a desired business objective, or to contribute to the achievement of that objective. [0003] In the existing workflow engine technical solution, a relational database is used as the context storage system of the workflow engine. The workflow engine will read the workflow execution status saved in the database and assign it to a specific task executor on a local or remote server node. Execute these tasks, and manage the state of the subtasks in the workflow until the execution of the entire workflow is completed. [0004] The wor...
