ODATA : Introduction to ODATA .

                   ODATA:Open Data Protocol

Hi All,
We are going to Start an entire Series of SAP ODATA Tutorial , we will be covering following topics in detail mostly screenshots and short desctiption and I will try to keep it short  and easy , as ODATA is little Hot in SAP Market.

, OData is the acronym for “Open Data Protocol”. The protocol is a set of rules which every player has to follow. To put it straight, OData interface is an open standard that can be consumed by any application, program, software or device of the Non-SAP World that can connect with SAP using the HTTP(s) protocol and can manipulate (read, write, modify and understand i.e. parse and construct) an XML document. Since the protocol is HTTP based, any programming language with HTTP stack can be used for consuming OData services.

The OData protocol supports serialization in multiple popular formats, including JSON and Atom/XML. With OData, developers are able to build cross-platform Web and mobile Applications.

SAP Netweaver Gateway
Th below figure shows that SAP NetWeaver Gateway sits in SAP Application Layer. It is the Window for outside world to peep into SAP and transfer data to/from SAP. Outer world can send HTTP(s) message and SAP would provide them with OData.

Microsoft originally developed and introduced OData.

What was the need for OData in SAP?
Ans: Before the introduction of OData, there was the “Point-to-Point” solution for SAP to Non-SAP integration. One application for two different organizations or platforms needed two different design in SAP. This led to duplication of work, effort, time and money.
