[Koha] MySQL and foreign keys

This goes along with my other email about modularizing authentication.
My feeling is that most of koha is sort of embedded, like auth the
storage should be modularized, like this
there should be a wrapper with default methods that do something a
default way, one of those would be search. the mysql search would use
mysql features (ie: full text search), a postgres search would do
whatever they do. basically you'd have custom queries for each DBM since
each method that does the querying would be DBM specific. Only the
parent class would hold static variables and things that would be
consistant across all the DBM's. If done this way storage is trivial,
one could store everything in flat text files if they wanted!.
I must emphasize that this is the *correct* way to program things like
this, and if we (my university) decides to use Koha I will certainly
help wherever i can.

Hi Again paul :)
Well maybe not 50,000 .. but 500,000+ ... its working ok for HLT's
But I take your point, and agree wholeheartedly the current search code
badly needs a rewrite and lots of optimisation.
And im sure HLT wouldnt say no to any speed increase :-)
I think what i was trying to say (bear in mind its getting late here,
mind is probably muddled :-)) was that we should be able to provide the
option for other people to use a database of their choice. Without
restricting those who want to from using mysql fulltext indexing.
On the topic of fulltext searching we had a discussion about it on irc
I cant currently get to the irc logs but when i can, ill mark the
and post the url to the devel list.
