Data model issues for object-oriented applications
TL;DR: The ORION data model as mentioned in this paper consolidates and modifies a number of major concepts found in many object-oriented systems, such as objects, classes, class lattice, methods, and inheritance.

Journal ArticleDOI
A model of authorization for next-generation database systems
TL;DR: A fuller model of authorization is presented that fills a few major gaps that the conventional models of authorization cannot fill for next-generation database systems and further formalize the notion of implicit authorization and refine the application of the notionof implicit authorization to object-oriented and semantic modeling concepts.
Journal ArticleDOI
Architecture of the ORION next-generation database system
TL;DR: ORION-1 as discussed by the authors is an ORION-based system that provides high-level data management functions, including query optimization, schema management, long data management (including text search) and support for versionable objects, composite objects, and multimedia objects.
Journal ArticleDOI
An object-oriented approach to multimedia databases
TL;DR: In this article, the authors identify data modelling and data access and sharing requirements which multimedia applications impose on a database system and show the capabilities of an object-based data model and indicate extensions which are needed to meet the data modelling aspects of these requirements.
