what is it and how do you use it?

it is a database.
a storage place for information.
can be used for things such as guestbooks, forums, and so forth where a buch of data needs to be stored and organized.
usually used in relation to PHP coding to connect and talk to it.
do a quick search of the forums or google for tutorials and such about it. it is a rather large subject to get into.

Don't forget databases can also handle large chunks of binary data, such as images. My site's avatar system stores all the item images in the database rather than flat files. Databases can handle any information you want to store in them, as long as the table structure is set up properly.

I know this isn't my post but I have a question about mysql.

Can Microsoft Access be used with MySQL? I was just wondering because I Access is a database program isn't it?
