How Accurate Was SAP on In Memory Computing?

Executive Summary

  • For years SAP has stated that on HANA and in-memory computing.
  • In this article, we review the accuracy of this claim. 

What SAP Said About SAP on In-Memory Computing

When SAP introduced, HANA has continuously claimed that HANA was utterly different than what had come before it. It claimed that a primary reason for this was that HANA was “in memory.” This led to other vendors copying SAP’s marketing as SAP convinced many customers that databases should be running entirely in memory, even though HANA never ran entirely in memory but simply had a large memory hardware footprint. You will learn how accurate SAP was in their claims around in-memory databases.

The Truth About In-Memory Computing?

As we covered in the article How to Understand Why In-Memory Computing is a Myth,

“Calling HANA “in-memory computing” is the same as saying “bullet based shooting,” when discussing firearms.”

All computing is in memory; no form of computing is performed without memory because the results would be unacceptable. On this computer being used to type this sentence, the program has been loaded into memory. HANA is differentiated from other databases in that it loads more of the tables into memory, but it does not load all of the tables. Secondly, no performance benefit has been demonstrated from HANA by following this approach over competing database offerings.

Conclusion and Calculation

SAP receives a 0% accuracy rating for the use of the term in-memory computing.
