You build the business entity model by adding nodes of different types. Each node type defines the nature of the relationship between the parent node and child node.
The business entity model can contain the following node types:
Business entity name
The name you give the business entity establishes the root node of the business entity.
one
Specifies a one-to-one relationship between a parent node and a child node.
For example, a one-to-one relationship between a Contact Address node and an Address node means that each contact address can only have one address associated with it. A person can have a home contact address and a work contact address, but only one address can be associated with the home contact address and only one address can associated with the work contact address.
many
Specifies a one-to-many relationship between a parent node and a child node.
For example, a one-to-many relationship between a Person node and a Telephone node means that a person record can have many telephone number records associated with it.
referenceOne
Specifies a one-to-one relationship between a parent node and a child reference entity node.
For example, a referenceOne relationship between a Person node and a Gender node means that a person record can be associated with only one gender value. The gender values reside in a lookup table.
