Databse dependant Website: What software?

Hi all,

I was wondering what software packages you would recommend to setup a database dependant website i.e. what database? what website authoring packages? and on which box?

At the moment I am only able to use the Macromedia Studio package but am not sure if I should learn another package to allow me to build a heavily database dependant website.

Any comments or suggestions will be much appreciated. Thanks in advance.

Andy.
