Dbd is based on set theory. What set theory calls a set, dbd calls a thing. In dbd, each thing is made of 0 to many elements which themselves are things. Dbd's interface is based on Lambda Calculus. For more info see en.wikipedia.org/wiki/Lambda_calculus

Dbd's "Natural Language Interface" is less "navigational" than RM's SQL in many cases. See examples in recent threads titled "How to find Brothers and Sisters?", "Bi-Directional Transitive Closure", "vehicle to autoparts relationships", "How to find persons who like red fruits or crunchy veggies?" and "Modelling Persons, Devices and Phone Numbers". Please post equivalent RMDB solutions to any of them for comparison. Received on Mon Dec 11 2006 - 04:56:29 CET
