Manual:Links table

<- MediaWiki architecture < Database layout

The links table stores all the links to existing articles. This is good for a variety of functions, from link caching in the output functions to the "what links here" page. It is the good twin of the brokenlinks table.

"DESCRIBE links" confronts us with:

l_from is the article title of the article that contains the link. If you want to ask "why don't you just store the cur_id of that article", don't.

l_to is the cur_id of the "target" article in the cur table.
