[comp.databases] User-Defined Indexes

benson@blake.u.washington.edu (Dan Benson) (10/13/90)

I am interested in the implementation of user-defined indexes in database
systems.  I have heard of the idea discussed in a paper associated with
Ingres (or was it Postgres?) but I don't know its status or other
references to this topic.  Does anyone have information on this?

My specific application deals with three-dimensional spatial data and
I would like to create a spatial index on this data.  I don't want to
build my own database from scratch but would like to be able to define
my own index structure to be used by an existing database management system.
Any ideas?

If there is significant interest/responses I will post a summary for
the net.

Thanks in advance,
