What SAP Said About SAP on In-Memory Computing

When SAP introduced HANA has continuously claimed that HANA was completely different than what had come before it. It claimed that a primary reason for this was that HANA was “in memory.”

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 there is no form of computing that 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, there is no performance benefit that has been demonstrated from HANA by following this approach over competing database offerings.
