Object Views and Query Modification

  • Chapter
Databases and Information Systems

Abstract

We attempt to widen the scope in which object views are typically set, following the paradigms of programming languages rather than traditional database concepts, such as relational/object algebras or calculi. A well-known environment stack is used as a semantic basis for definitions of query operators. In this setting naming, scoping and binding are central issues and a virtual (non-materialised) database view is a stored function. A function output is a structure built upon atomic values, references and names. Such functions perfectly simulate virtual objects and virtual classes. The approach can be coupled with the query modification technique based on macro-substitution. It significantly reduces performance problems related to processing views. The approach is relevant to object query languages such as OQL.
