The binding path syntax for OData models matches the URL path relative to the service URL used in OData to access specific entries or collections.
You access the data provided by the OData model according to the structure of the OData service as defined in the metadata of a service. URL parameters such as filters cannot be added to a binding path. The following samples of bindings within the ODataModel are taken from the well-known Northwind demo service.
Absolute binding paths:
/Customers /Customers('ALFKI')/Orders
Relative binding paths within a Customer context:
CompanyName Address Orders
Relative binding paths within an aggregation binding of "/Customer('ALFKI')/Orders:
OrderID ShipName ShipAdress Employee/LastName Order_Details/Discount
