Transparent SQL proxy

Published by pj under design, opensource

I’m about to start a new project: a transparent SQL proxy. Connect your PHP-app to this “fake” mysql server, which sits in between your app and postgresql server translating all mysql-specific queries to normal sql’92 compliant format.

Requirements:

  • support backend connections to postgres
  • emulate mysql behaviour to frontend
  • in Release1, queries for ‘X-cart’ shopping cart software should be supported

I have a clear picture of this. Does anyone have more ideas to contribute? I’ll start designing in the next few days.

Fun with graphviz and dot

Published by pj under design, dot, opensource

I am currently using “Graphviz” to visualize the design of a use case model within a wiki environment.

(Trac plugin: http://trac-hacks.org/wiki/GraphvizPlugin)

Consider this line:

pie->I->like->pie->yummy->I->yummy->like->I->pie->like->yummy->pie

Resulting in this picture:

Example of Dot's usage

Delicious!
