Abstract
The ALDOUS90 project is originated in the difficulties met in realizing complex expert systems (in CAD, CASE, ...) using commercial shells such as KEE: they provide a good set of facilities for developing expert systems, but as the amount of data increases, their performance drasticly decreases. Object-oriented databases, such as O2 of the GIP-ALTAIR, optimize object management which is not done in these shells. The ALDOUS90 is aimed at giving O2 functionalities similar to KEE: a first-order rule language, a context mechanism (versions), a context management system (a powerful inference engine), an extended ATMS (to maintain consistencies of versions, schemas and objects), an extended RETE algorithm (to select rules), an inferential distance algorithm (to solve conflicts in multiple inheritance) and a device to add default values to classes.
