I'm new to MySQL and never took a class in it. I have two questions.
1)) Can anyone suggest a good book to learn MySQL quickly.
2)) Can someone tell me how to set up a database that contains user accounts that can then be linked to other databases. For example: If I were to install PHPBB3 and MediaWiki I'd like to be able to share users between the two so that only one login is necessary. Then I'd like to store the data from each of those sites separately in their own databases or at least their own tables. I don't want to use any plugins for MediaWiki or PHPBB3 because this rules out expanding the site to include other types of pages.
Any help provided would be of great help.
