I was in charge of a commercial computer installation in 1967 that had 4K of main memory ... about 500 HP of air condition power ... and used a tractor trailer's worth of punched cards every week. But even with this rather modest computing capacity we were able to do some fairly amazing things compared to what went before. Our efforts were written up as Harvard Business School cases back in those times.
The computation power that now exists should be enabling amazing analysis and in turn amazing conclusions and predictions. In the field of weather forecasting, massive computer modelling is giving very good resuls ... though it has not yet been able to prove that global warming is caused by human activity, which I might possibly argue is something that can never be proved even if it is actually so. This is actually important, because the casuation around many important matters cannot be proved, but even so important decisions still need to be made.
The possibility that scientists associated with SAP could actually take something like TrueValueMetrics and use it in a computational environment that has the power to model economic progress and performance in any community on the planet, and then aggregate these results so that countries, regions and eventuall the progress and performance of society as a whole can be optimized gets to be probable, not just possible or a silly dream.
Setting The Record Straight - SAP HANA v. Exadata X3
At the Oracle Open World keynote this week, Oracle repeated what Hasso showed years ago - 'Everything is in memory…Disk drives are becoming passé.' We are, of course, glad they realized this. With SAP HANA, our customers have been benefiting from this reality for more than 18 months now.
And yet Oracle made statements that are clear distortions and misrepresent HANA. It has become something of a recurring theme, to mis-state and distort things. As industry leaders, we must do better. It behooves us to tell the truth to our customers, our partners and our employees. We do not serve our stakeholders well by mis-statements and omissions of key things we know to be true. They deserve better. History deserves better. It is true that HANA represents a fundamentally new, rethought, database paradigm, and is receiving tremendous success in the market. Perhaps it is its disruptive nature that threatens the status quo of database incumbents. Perhaps it is some other reason. Regardless, I find myself once again setting the record straight.
The statement Mr Ellison made about HANA, when talking about the release of a new Exadata machine, that has 4TB of DRAM and 22TB of SSD, is false. He referred to HANA being 'a small machine' with 0.5TB of memory. He said his machine has 26TB of memory, which is also wrong (SSD is not DRAM and does not count as memory, HANA servers also use SSDs for persistence).
Here is the truth:
HANA is built on a simple notion: advances in hardware, and deep research into the nature of modern enterprise software, enable us to rethink the database. And we did. I treated this notion as a design principle for HANA’s construction. Others are trying to protect their database systems that were designed in the past. The use of new SSD access technology, which accelerates access to flash and demonstrates performance improvements, simply reinforces this point. HANA also benefits from this technology, for reading logs, for restart performance, etc. as do our ASE and IQ databases. But HANA is built on a basic principle that Hasso had articulated many years ago: when we run everything in-memory, we can get predictable response times on even the most complex queries and algorithms, and everything can execute with massive parallelism. This power gives us the freedom to rethink enterprise software. To renew existing systems without disruption: from OLTP apps (such as our Business One product that we released on HANA last week), to Analytics, from structured data processing, to unstructured. To rethink systems to run 1000s of times faster, and to eliminate batch jobs everywhere. It also gives us the ability to build completely new applications, unprecedented solutions. To help software simplify the world, and connect it better, in real-time: from genome sequencing to energy exploration, from real-time customer intimacy, to inclusive banking. To liberate us from the confines and limitations of systems of the past, and enable us to be limited only by our imagination.
As Alan Kay always told me, the future does not just have to be an increment of the past. We choose to focus on the future, on building a highly desirable, feasible and viable future, with our hands, with our customers and partners. Instead of focusing on incrementing limited systems of the past with temporary technologies. And we think there is no room for lies in that world. The truth of a HANA based landscape, and its unmistakable success, is open to all, and it is ours to take and build on.

|TrueValueMetrics (TVM) is an Open Source / Open Knowledge initiative. It has been funded by family and friends. TVM is a 'big idea' that has the potential to be a game changer. The goal is for it to remain an open access initiative.
|WE WANT TO MAINTAIN AN OPEN KNOWLEDGE MODEL
|A MODEST DONATION WILL HELP MAKE THAT HAPPEN
