Open Data Protocol (OData) defines a protocol to query and update data that utilizes the existing Web protocols. OData is a REST-based protocol that is built on standardized technologies such as HTTP, Atom/XML, and JSON. It is different from other REST-based Web services. It provides a uniform way to describe the data and the data model.

It is a flexible technology to enable interoperability between data sources, applications, services, and clients.

OData actions provides a uniform way to query and manipulate data sets through CRUD (create, read, update, and delete) operations as well as execute actions and functions . For more information, refer to the OData website.
