OData and FndODataProvider¶
OData (Open Data Protocol) is an ISO/IEC approved, OASIS standard that defines a set of best practices for building and consuming RESTful APIs. OData APIs are easy to consume. OData metadata, a machine-readable description of the data model of the APIs, enables the creation of powerful generic client proxies and tools.
