A workflow schema is a graphical representation of a workflow that shows the workflow as a flow diagram of interconnected workflow elements. The workflow schema defines the logical flow of a workflow.

Building a Workflow in the Workflow Schema Workflow schemas consist of a sequence of schema elements. Workflow schema elements are the building blocks of the workflow, and can represent decisions, scripted tasks, actions, exception handlers, or even other workflows.
Schema Elements and Schema Element Properties The workflow editor presents the workflow schema elements in menus on the Schema tab. You can use the schema elements available in the Schema tab to build a workflow.
Links and Bindings Links between elements determine the logical flow of the workflow. Bindings populate elements with data from other elements by binding input and output parameters to workflow variables.
Decisions Workflows can implement decision functions that define different courses of action according to a Boolean true or false statement.
Exception Handling Exception handling catches any errors that occur when a schema element runs. Exception handling defines how the schema element behaves when the error occurs.
Foreach Elements and Composite Types You can insert a Foreach element in the workflow that you develop to run a subworkflow that iterates over arrays of parameters or variables. To improve the understanding and readability of the workflow, you can group several workflow parameters of different types that are logically connected in a single type that is called a composite type.
Add a Switch Activity to a Workflow You can add a basic switch activity to a workflow schema that defines the switch cases based on workflow variables or parameters.
