Are you curious about what is REST and OData? Then, this article is for you. In it, you will find an explanation of what is REST, how it is applied to the construction of RESTful APIs; what is OData and how it is used to build web services, and the differences between the two. Brief comparison The table below summarizes the main similarities and differences between REST APIs and OData Services. Table1: REST and OData comparison As the table shows, both technologies follow REST principles, although OData is more relaxed in that, if there is a good reason to avoid its use, it lets you do so. Thus the OData Protocol is more comprehensive than the REST model, as in addition to the use of the REST principles, it provides a way to describe both the data and the data model. So, let’s go deep into the details by explaining each of the concepts mentioned in the above table. What is REST Representational State Transfer, or better known as REST is a software archi
ABAP Managed Database Procedures – Introduction What are AMDPs… ABAP Managed Database Procedures are a new feature in AS ABAP allowing developers to write database procedures directly in ABAP. You can think of a Database Procedure as a function stored and executed in the database. The implementation language varies from one database system to another. In SAP HANA it is SQL Script. Using AMDP allows developers to create and execute those database procedures in the ABAP environment using ABAP methods and ABAP data types. This video will show you more details… AMDPs are introduced to easily enable you to get the best out of ABAP for HANA following the “code push-down” paradigm first introduced with SAP NetWeaver AS ABAP 7.4 last year. More information on this paradigm can be found here: ABAP for HANA and “Code Push-Down” . … and why should I use them ? As you can imagine (and hopefully have already experienced) calculations executed while retrieving the data f
