[Haskell-cafe] Information on B-Tree IO implemenations

[Scott Weeks]

Hello all,

(I'm resending this because I sent the first one without being a member 
of the list and I'm assuming it bounced)

I'm a newbie and while I grasp some of the basics of FP I have yet to 
really understand the guts of Haskell. The type system is starting to 
clear up for me and so are Monads but I have a long way to go.

For a project that I'm working on I need to implement a B-Tree or 
similar disk based data structure for storing large amounts of data. I 
feel like I'm getting it and then I get hung up on disk IO operations 
and trying to figure out how they should fit into the mix.

I'm not necessarily looking for someone to point me at an 
implementation (although I wouldn't mind) but if someone could point me 
in the direction of some material that could shed a light on things I 
would be much obliged.

I've read some Okasaki and found a promising paper called "Database 
Manipulation in Haskell 1.3" by Kevin Hammond and Phil Trinder but 
while they talk to the data structures themselves they don't quite get 
around to mentioning how they achieve the IO part of the equation.

Thanks,

Scotty Weeks
