RE: Jim Gray article on Next Generation Databases
Which is why Alan Kay says software development is a pop culture: it recycles songs, ideas, and people in accordance with bandwidth, processor power, and depth of understanding (necessarily shallow and not always historically aware). But the interesting part is that the Gray clearly articulates that unstructured and weakly structured data isn't going away, so we should deal with it. If that means pulling out ways we understand that are simple, approximate and reliable even if old, so much the better. I'd rather deal with prior art frankly. I began looking at quantum logic (fab if you had the hardware) but found I circled back to VSMs because a) they work and b) we understand them. In the Hytime standard, there is a locator type called fcsloc (finite coordinate system locator) that was applied to page layout. But at the time, we discussed how the same kinds of locators could be applied to conceptual maps such as VSM produces. Things diverged into topic maps but I suspect that they will converge again shortly and as typical, in a simpler form. Using a VSM approach to generate a first cut or tunable topic map isn't that far-fetched. len From: Bob Wyman [mailto:bob@w...] Claude L Bullard wrote: >I like this part: > "One interesting development worth noting, however, has to do > with the integration of database systems and file systems..." This is a "development"? Doesn't anyone remember VAX/VMS? It had RMS (Records Management System) which presented the user with a choice of file types: sequential, block I/O, record oriented, indexed, etc. All built-in. Having indexed ISAM files as a core function of the operating system was a wonderful thing... I remember meetings in the mid-80s when we were seriously considering bundling a stripped down version of RDB (our relational database) as a component of the VMS operating system as well. The thinking was that since we could see how all of our application products would be enhanced if they used RDB for data storage, it might make it easier for us to build and ship products if developers could simply assume that there was an RDBMS available on every platform. bob wyman (ex-DEC)
