The business entity model is a tree model of nodes. Each node corresponds to a base object table in the MDM Hub. Each field corresponds to a column of a base object table in the MDM Hub.
The business entity model is based upon a root node. The root node is synonymous with the business entity. For example, a business entity model with a Person root node is considered to be a Person business entity.
After establishing the root node, use the tree panel to create child nodes that have a one-to-one or one-to-many relationship with their parent nodes.
