Free Database Hosting
One of my friend was asking me whether there was any website which offers PHP with MySQL database. I suggested a few like Portland.co.uk and others. But most of them were offering only PHP. After a brief research and just I recalled about FreeSQL which was giving free MySQL hosting.
When I visited the website (http://www.freesql.org/), it is now offering both MySQL and PostGRESQL for free. The website also offers powerful interfaces to the databases through PhpMyAdmin and PhpPgAdmin.
I think this website should be of tremendous help for novices and learners in database systems to learn and practice effecient database programming.
