The term SAP HANA is used for both (in-memory) database and an application platform.

SAP HANA is a platform offered as both an appliance and a cloud service.

SAP HANA in-memory database is a specialized database with following features

  • All the read & write operations, take place in memory.
  • Data can be stored both in row and column format.
  • Every column is a secondary index and there is no need to maintain separate indexes.
  • It has a much better Data compression as data from the same column can be stored together
  • It utilizes distributive, multiprocessing & massive parallel processing capabilities of modern CPUs.

It comes with a tightly integrated lightweight application server out-of-the-box, SAP HANA XS or Extended Application Services. SAP HANA XS is esigned/engineered specificly for SAP HANA database and is closely integrated with it to take care of

  • validation logic
  • control flow logic
  • service enablement logic

as most of

  • calculation logic
  • data-intensive processing

are pushed down into the database layers to leverage the power of the features mentioned above.

HANA Extended Application Services uses

  • server-side JavaScript as the main programming language 
  • supports REST-based OData services with both JSON and Atom XML rendering

using which complex transnational business applications can be build.


Data-intensive logic can be written in

  • SQL and SQL Script and
  • it also has built-in support for XML for Analysis (XMLA) and Multidimensional Expression language (MDX) access for analytics.

The above information is just to get started. I would keep updating this blog with more up-to-date information.

    Hey Tarun,

    SAP HANA is around now for 2 years and meanwhile quite a lot of information had been released about it. Some of it really well written, well researched and produced content. Look e.g. what people like Ravindra Channe release.


    And yet you manage it to come up with this list of bullet points with claims of product attributes and don’t bother bringing any backup or examples or anything like that to it.

    Also, I was under the impression that this community was meant to be used in Chinese…

    I’m sure there’s more you can say about SAP HANA and that you have better ways to do so.

    Come on then – let us see that instead!

    – Lars

      Thanks Lars for sharing details about prominant contributors to HANA topics. I would keep updating this blog, hopefully it should get better and better over time. I just realized the space HANA Developer Center would have been more appropriate, I would move this soon to an English space.
