Abstract
Described are a system and methods for exchanging information between heterogeneous databases (28,28'). A constructor (54) produces a first semantic network (58) representation of a first database (28). A concept matcher (52) identifies semantic concept equivalencies (64) between the semantic network (58) representation of the first database (28) and a second semantic network (58') representation of the second database (28'). A query processor (66) uses one of the identified semantic concept equivalencies (64,64') to generate a request to access data from the second database (28).
