Workflow systems can be divided into three layers from logical structures: 2 task layer
There are a certain rules and format forward or reverse task flow, responsible for the connection of two working nodes before and after.
2 workflow engine
Based on the specified process rule, in conjunction with the current application environment, determine the core module of the task flow or generate a new task stream.
2 Process logic layer
Composed of flow configuration, application configuration, and environment. Process configuration is primarily configured for workflow configuration, step configuration, and access conditions; application configuration and environments refer to the configuration of institutions, personnel, and role permissions in the system, and application environments formed during transaction schedule.
The workflow engine will read the task flow data from the task layer according to the requirements of the system trading platform. After receiving the task flow data, read the flow configuration, application configuration, and environmental data from the process logic layer. The workflow node connection is completed by matching the running data and configuration data.
The reverse task flow also uses the same rule.
