The building of an object distributed database management system (ODDBMS) integrates the linked concepts of the distributed database management and the linked concepts of objects. Among the object concepts, the author focuses interest on the following two concepts: inherit link and reference link. The author studies how these links, adapted to a distributed system, influence the global request (transaction) decomposition into local sub-requests (sub-transactions). The author also studies how these links have to be taken into account during the different types of management that the distributed system has to use in order to be consistent and reliable. The originality of the proposition is that one integrates the inheritance concept in a distributed system by extending it to an aspect related to duplication. A class which inherits from another class implanted on another site sees its inherited attribute occurrences duplicated on its implantation site. The author proposes with an example of ODDB, an implementation of the methods used in description of classes and shows how they can be used in examples of update transactions
