How can I import tables or databases?

You have to go to the section Admin tools in the TYPO3-Backend and choose the subsection phpMyAdmin. Go to the section Import in the tab-menu on the top (fig.6). Click Browse and select the file which you want to import (possibly see the 
FAQ ‚How can I export individual tables or databases?’ before). After you chose the file, confirm with Ok down right.
