I'm working on a big site project.
But, I still have got a problem, databases.
I heard things about it but don't know 100% how they work etc.
I want on my site:
A button that people with permission can change the colour of
A moderated chat
News announcement on the homepage
That I can add URL's without re-upload the site (if possible)
I don't know what to use for it.
Can I use things like baseportal.com for it? How?
Do I really need to code the databases? Goes it free? What are the differences between different database-languages?
Thanks for helping!
