Storage management for persistent complex objects

摘要

The emerging generation of database systems and persistent programming languages presents a new set of requirements for object management systems. In this paper, we first describe these requirements and provide a survey of prior efforts to address these issues. We then present an object model with the descriptive power to satisfy these requirements. Finally, we propose a modular architecture for an object manager which will provide efficient support for the storage, retrieval and modification of persistent complex objects. The object manager hides the internal structural details of objects from its clients. It provides direct support for indexing and does not impose any size restrictions on objects.
