(Here’s The Register’s take on it.) One figure they cite is a 100-fold+ improvement in access speed. The speed difference between disk and silicon, of course, is something I’ve focused on in my research into memory-centric data management, and also in some of the work on data warehouse appliances as well. They are proposing this as the entire fixed memory for laptops. And in a much cheaper vein, Nicholas Negroponte is proposing a diskless architecture for the 100-dollar laptop.

In essence, it’s a product that’s all RAM-based, and generally geared for multi-hundred-gigabyte data marts. The basic design is a compression-heavy column-based architecture, evolved from SAP’s text-indexing technology TREX. Like data warehouse appliances, it eschews indexing, relying instead on blazingly fast table scans. I asked Lothar Schubert of SAP how BIA was doing in the market in its early going. This was his response: [...] [...] I wrote about SAP’s BI Accelerator quite a bit in my white paper on memory-centric data management, but otherwise I seem not to have posted much about it here.

Notwithstanding that this was a relatively longstanding meeting, Linda scheduled a dinner for us in Cambridge with my stepdaughter, which is basically good, because Intersystems is in Cambridge, but forgot about my meeting, and wound up scheduling the dinner for 9:30. Rescheduling ensued, but when I drove to Intersystems for a 2:30 meeting, it was still in flux. I was in an odd state anyway driving to the meeting, because I was already rather tired (my sleep schedule oddities), but psyched from having FINALLY posted the white paper online that represented my biggest writing project in almost a decade (because of the number of sponsors).
