About 3 years ago SAP started to create a new database engine, SAP HANA, with a pure In-Memory concept. SAP aggressively move it's new database to it's software stack. The database was not used as cache but for running Enterprise Application satisfying both OLTP and OLAP demands on the same database.
As oracle announced the new Oracle 12c in late 2012 there the 'c' was for cloud based computing, means the simplification of creating several database instances under the hood of a container parent database. For the end user this wasn't a visible benefit. It seemed Oracle did ignore SAP HANA. But even you cannot compare number installed databases for SAP HANA and Oracle HANA made an impact. Something new and very visible to the end user arises.
Now about a half year Oracles In-Memory Option announcement the European launch event was done on Tuesday this week. In the radison Blue hotel - which was a very exciting and comfortable place for that - the conference room was much more filled up with the oracle followers then the soccer arenas of this years soccer world championship.
The event was well organized and mixed up with high professional speakers.
What still in my mind was ...
Maria Colgan introduced the more detailed usage and environment of the Oracle In-Memory Option. She did it in a so clear and compact form - I am really impressed. Also the life demos have been amazing.
I was also impressed about Dr. Maaike Limper's session. She works as scientist at CERN; and tested to use the In-Memory Option to get faster analysis about particle collisions and used a data model of particle typed tables with hundreds of parameter per particle and immense number of rows. By using the In-Memory Option she said it was possible to play with data to drill down and possible find something new due the detected data patterns of the sampled particle sensor data.
Finally Dr. Dietmar Neugebauer held a session like 'is the DWH dead now?' which proofed clearly the DWH is not only about analytic queries and so superfluous but also to consolidate and validate data from different data-sources/systems of the whole company. So the DWH is not dead with introduction of the new In-Memory Option. Maybe some 1:1 replication of operative data will get obsolete.
At the end of the event everybody knows and feels something has happened in the database world which will be visible for all end users and will have a tremendous effect on system landscapes and software development - back to database centric ultra-fast processing.
