Abstract
In database management systems, viewing mechanisms have been used to provide conceptual support for the user and security for the overall system. By controlling the style of database use, views aid the user by concentrating on the area of interest, and the system by ensuring the integrity of the data. In recent years, there have been a number of proposals for database or persistent programming languages. Such languages must be able to provide the facilities traditionally found in both database management systems and programming languages. In this paper we demonstrate how a persistent programming language, Napier88, can provide a viewing mechanism over persistent data by using existentially quantified types. The views, which may be generated dynamically, are statically type checked. The technique shown is applicable to any language which supports existentially quantified data types and a persistent store.
