HANA Question

Postby Martin_US » Tue Jul 02, 2013 8:28 am

Hi Guys,

seems to be a lot of hype about HANA. Can someone please point out the key features in a simple way compared to traditional databases? Specifically why would anyone worry (performance aside) what the underlying database is?

Thanks
Martin

Hi Martin

HANA is more than just a database. it is an application platform, database and hardware combination.

NANA changes the whole SAP Database concept. it reduces the size of the database by storing data in columns instead of rows. it uses dictonary objects to reduce the size of the tables and compresses the data.

The way you program on HANA removes the need to extract the data from the database before performing logic. it enables you to run the business logic within the database removing bottle necks for processing.

13 years after, I still have the Miata... :mrgreen:
Now seriously, HANA is SAP's answer to all the migrbibling going on between Oracle & SAP, they have sued each other's pants and now the battle is getting worse with the emergence of HANA. It is clearly SAP's intention to wipe Oracle (and all other RDBMS) off SAP installations and support only HANA as THE database not only for Warehousing but for Netweaver, IS-U, etc. AFAIK , SAP is already talking about a deadline for users to migrate to HANA.
Of course this could also mean the downfall of SAP. It took Oracle about 8 years, till Release 6, to make a robust, dependable product. Sqlserver has not even made it after 12 years of trying! :roll: So, HTF do you think SAP is going to do in 3 years what it has taken others many years to mature?? This ain't ending well.

I think SAP is leaving it's core business and has for some time. I understand that there might be some pressure from large customers, but taking on all those side parties can't be healthy.

Worse, but not quite SAP's problem, it seems more and more projects are set to fail because of unreasonable expectations. I would really like to meet more competent IT managers. I think those folks are to far away from the war zone.

Instead of supporting all kinds of interfaces, SAP should establish a clear strategy. This what we do, this is how it is done, those are the tools we provide. End of story.

SAP it seems is driven by exceptions, just like most clients, instead of putting the focus on the money maker.
SAP should also provide a very stringent certification for consulting companies to get rid of the weed.

As for Oracle and MS: If you need a DB admin, then go back to school and look at DB2.
