Dont know any books, but have you read the wikipedia page?
Try any book by Edgar F. Codd. While at IBM he developed the concept of

I've been having a look at memcached. I would like to ask, is there any
reason that, theoretically, a similar caching system could be built

I.e., the hash tables and libevent

This is all a bit above my head, but have you looked at pgmemcached?

How does the cache know when the database contents change?

This is exactly what I was asking about. So my theoretical idea has
already been implemented. Now if only *all* my ideas were done for me by
the time I came up with them :)
Then you wouldn't be able to eventually patent them ;)
What an un-BSD licensish thing to say :P

I have always found MySQL's query cache to be utterly useless.
Think about it this way :
It only works for tables that seldom change.
It does not work for big tables (like the posts table of a forum)
because the cache would have to be huge.
So, the most frequent usage
