Context Node Behavior at Design Time and Runtime 

You can create a context structure at design time by defining nodes and attributes. However, these nodes represent a collection of data objects at runtime. The elements of this data object collection are called node elements.

The following diagram shows that at runtime, a node contains a collection of elements whose attributes you defined as node attributes at design time.

Context structure example

Parent nodes:

Value node “Customers“, collection type=list, cardinality=0..n, selection=0..n

Value attribute “Name“, type String

Child node:

Value node “Customers.Orders“, collection type=list, cardinality=0..n, selection=0..n

Value attribute “OrderItems“, type String

 

You see that multiple orders can be assigned to each customer and that each order can have multiple order items. Therefore, the context structure contains child nodes. A collection of child node elements belongs to each element of a parent node.
