Hi there in net land!

	I am cross-posting this origional, but the followup line
should be right so try not to flame me too badly.

	I am looking to do a "look see" database, something that will
be resonable useful for most situations, and simple enough to
understand. With the wide range of experience on the net, I wnat to
ask you all.

	What I have now is a VERY simple DB structure, in this form:


Index					Data
===============================================================

KEY                              --->   KEY
OFFSET ------------------------/        SIZE
					DATA

	The index will be read into memory, as you can see, the DB
handles variable length records.  When a record is deleted, I will set
the key to -1 and delete it's index. I will ignore the holes this will
leave in the db file for now.

	Sorting the index is not needed, it will be in a hash table in
memory. That doesnt matter much, I am looking at more general theory
now.

	What other ways are there to do this ?

	Please reply by mail and I will summarize, or followup.

	Thanks!
