In this talk I describe OB1, an object-oriented database facility. OB1
is a hybrid query language that incorporates most of the features of
relational query languages plus "view/objects" that allow sets as
values and recursive views. OB1 is implemented in Quintus Prolog and
includes server facilities that allow C & Fortran clients to query an
OB1 server over a SUN network. OB1 also has a graphics
Entity/Relationship data modeling editor used to design OB1 databases.

Ben will be here friday, October 23, from lunch time till 5 - I suppose
