Context

The schema entities and relationships defined for a data store are known as the context.

Context helps you when authoring rules and actions. It defines which classes you can select when picking class and attribute names.

Without a context, the names of classes or attributes have to be typed by hand. With context selected, they can be chosen from lists based on the schema of the data stores selected.

Note: The context is not used when running the rules or actions (as the data stores to be opened are defined within the session) but only when authoring them.

The Context tab is found within the Navigation Pane of both the Rules and Actions interfaces.

Note: If the context is updated in the Rules interface, it will also be updated in the Actions interface. You cannot have different context for Rules and Actions.

Use Schema

If Use schema is selected, a list of available data stores will appear.

Note: Multiple data stores can be selected for the context.

Once at least one data store is selected from the list, available classes will be available to be selected as parameters for:

• All conditions except Test in Range and the logical operators
• Any of the following operations:
  • Loop Over Objects
  • Loop Over a Collection
  • Create Object
  • Delete Object
• Any of the following values:
  • Dynamic Value
  • Object or Element
  • Class Name
  • Nested Value
  • Array Element
  • Aggregate Value

Note: For values, attributes are also available when the context is defined.
