Workflow Orchestration Service Module

Workflow Orchestration Service Module

The Workflow Orchestration Service Module manages requests to run workflows.
When you start a workflow instance in a deployed application, the Data Integration Service receives the request. The Workflow Orchestration Service Module runs and manages the workflow instance. The Workflow Orchestration Service Module runs workflow objects in the order that the objects are connected. The Workflow Orchestration Service Module evaluates expressions in conditional sequence flows to determine whether to run the next task. If the expression evaluates to true or if the sequence flow does not include a condition, the Workflow Orchestration Service Module starts and passes input data to the connected task. The task uses the input data to complete a single unit of work.
When a Mapping task runs a mapping, it sends the mapping to the LDTM for optimization and compilation. The LDTM passes the compiled mapping to a DTM instance to run the mapping.
When a task finishes processing a unit of work, the task passes output data back to the Workflow Orchestration Service Module. The Workflow Orchestration Service Module uses this data to evaluate expressions in conditional sequence flows or uses this data as input for the remaining tasks in the workflow.
