Schemaless MySql Database System May 1st, 2009

A few months ago i saw a blog post about friendfeed’s new approach to their database. just now during the mayday i found enough time to prototype an application of it. its called matDb and its very simple to use. I haven’t debugged it enough to use in a full scaled application but it’ll be pretty enough for little projects :) . Here’s a little example of matDB: http://pastie.org/465133.

And the outcome if the test application i linked above is:

As you see its pretty simple & straightforward you can read the original article which also includes indexes and compression here.

And the files are here for you to use & test :D .
