Is this opening book database used for the UCT portion, or the playout portion
of Orego? In the UCT portion, speed of access may not be that important; a
database would probably be ideal. If used during the playout, then speed of
access is more crucial.

What type of data are you trying to serialize or rather store to disk? Do you
have pointers in the data. Don't tell me you don't have pointers just because
it is java. Java has pointers, it just preteneds it doesn't. Show us the
datastructure and we can probably help you more. If each entry has no pointers
than your task should be pretty straightforward. If you do have them, you are
going to need to find a way to store those so that they are able to be
redetermined. In a language like java, where you can't do pointer arithmetic
or anything of the sort this can get rather difficult. Also, have you
considered using a database instead of a flat file to store this data?

Peter, java serialization is not a good way to do persistent storage
of any kind, especially large data structures.
It has some pretty severe drawbacks:
- It is slow
- It breaks easily (ie, becomes unable to load older data sets) when
you make even small changes in your code.
- It makes inefficient use of space
- The format is difficult to decode or manipulate in any way other
than reading or writing with the exact .class file used to generate
the serialization code.
Java serialization is excellent for RMI, but is pretty poor for any
other use. I've used serialization myself several times and I
regretted it every time (except for when I used it for RMI).
My advice would be to come up with your own data format and use
that.
