I am still learning it too actually. What web development program are you using? I use Dreamweaver CS3, which works well with php/mysql. From what I know is that if you are looking to have something affordable and that holds alot of data, you would want to go with mysql and php. It looks really confusing but is actually not too bad. The main thing you need to figure out is how you want your database set up as in tables... A good book I have and went by is Dreamweaver CS3 with CSS,Ajax, and PHP by David Powers. It gives a rundown of databases and how to create search engines and retrieve data. Another thing is the Sams teach yourself in 10 minutes mysql. There are alot out there, best thing to do is go to amazon and type in which one you are looking for (mysql, php, asp, etc.)
