Morning Tim,

>> Any info on the subject would be greatly appreciated!

in addition to the information provided by Ann and Helen, there are
plenty of docs available at http://www.firebirdsql.org/index.php?op=doc
some older, some newer and all useful.

One in particular - which is a work in progress - that may help is
http://www.firebirdsql.org/manual/fb-internals.html (online version) or
http://www.firebirdsql.org/pdfmanual/Firebird-Internals.pdf
(downloadable pdf version).

Other useful docs can also be found on the IBPhoenix web site at
http://www.ibphoenix.com/resources/documents/ especially, in the case of
your original query at
http://www.ibphoenix.com/resources/documents/design.

And finally, don't forget Helen's book - "The Firebird Book" (details at
http://www.ibphoenix.com/products/books/firebird_book) which you can buy
online from Amazon etc, and the supplement the IBPhoenix site at
http://www.ibphoenix.com/shop/category/4?cur=GBP


Have fun.


HTH

Cheers,
Norman.
