What is the Open Data Protocol (OData)?

OData for SAP

OData

Atom Syndication

XML

HTTP(S)

OData is a Microsoft developed extension to the Atom Publishing and Atom Syndication standards, which in turn, are based on XML and HTTP(S).

It was designed to provide database-like access to server-side resources. Hence, OData has been described as:

“ODBC for the Web”

It can be used freely without the need for a license or contract.

OData is also extensible. This allows SAP to supplement the data types used by OData with extra information from the ABAP Data Dictionary.
