Hi there See link: www.Kx.com I am a newbie with Zope; just went through some docs and keeping an eye on this list. Cool tool ! I like to point out to a database I came across a while ago: Kdb. It is a very small application, written in the language k. The total download is only 400 kb ! The database is build to be very fast.
From what I understand it stores data in fields instead of records as 'old' databases do. It also tries to keep everything in ram and is very efficient using it. The company behind it pushes the product for analysing very large datasets: telephone-companies, minute to minute share-prices and such. From what I read and heard the speed is really incredible !! The commercial version starts at about USD 5000, but their site has a free testversion available which can hold easily a few million records ... That not all: they believe accessing the data is very important (ok, ok) and offer interfacing with java, Visual Basic, odbc, etc but most interesting also something like "http://localhost:2080/.xml?select sum amount by stock > from trade". Have a look at the company: www.kx.com
