In OData, a navigation property is a property on an entity that is itself either a single entity or list of entities.

A single-entity navigation property signifies a one-to-one relationship. For example, consider the GWSAMPLE_BASIC SAP Gateway endpoint. The ProductSet contains a ToSupplier navigation property, which references a single BusinessPartner entity.

An entity set navigation property signifies a one-to-many relationship. For example, consider the GWSAMPLE_BASIC SAP Gateway endpoint. The ProductSet contains a ToSalesOrderLineItems navigation property, which references many SalesOrderLineItem objects.

Working with Navigation Properties Relationally

Navigation properties in OData link related entities. Similarly, in a relational database, a foreign key serves to link tables. For example, the SalesOrderLineItem record contains the ProductID column, which uniquely identifies what Product the SalesOrderLineItem is using.
