Data access and storage in an entity relationship database system
A description of the design of a database system based on the entity relationship model is given with particular reference to the data storage subsystem.
The setting-up of a database project at Manchester University is described together with the initial implementation of the database system which evolved from it. The criteria for the choice of the data model to be used are discussed and four data models are considered. The reasons behind the final choice of the entity relationship model are given.
A description of and the reasons for the modular design of the system are presented. The structure of the data storage subsystem is described and two data storage models are discussed.
Details of the database system's data access primitives are supplied together with a description of the mechanisms used to implement them.
