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 cur_id of the article that contains the link. (This is a change from 1.2, wherein the title of the article was stored. This was brain-damaged, and has now been fixed.)

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