Remarks

In this property, you write codes to return an ArrayList which contains the relations' definition of all your objects.

The purpose of Relations getter property in IObjectRelations interface is simply to collect the definition of each relationship between one business entity and the other.

In this concept, you used the special WebGridObjectRelation object provided by WebGrid.NET for objects relation.

Use the WebGridObjectRelation object to provide the necessary information, such as:

The ParentCollection Type, such as CustomerCollection
The ParentMember property, such as CustomerID. In business object, the parent member is a public property having the same name as the property name.
The ChildCollection property, such as Orders. The child collection is a public property defined in the parent class which is used to get the collection of child objects.
The ChildCollection Type, such as OrderCollection
The ChildMember property, such as CustomerID. The child member is a public property defined in the child class (which is Order class in this context).
