This paper describes the basic data model of an object-oriented database and the basic architecture of the system implementing it. In particular, a secondary storage segmentation scheme and a transaction-processing scheme are discussed. The segmentation scheme allows for arbitrary clustering of objects, including duplicates. The transaction scheme allows for many different sharing protocols ranging from those that enforce serializability to those that are nonserializable and require

Pages 70-95. * Our use of the term partition does not imply mutually exclusive sets of database objects but a lower level clustering of both replicated and nonreplicated objects.
