Abstract

A customer purchasing a product may select one variant among the several alternatives available for a component, and may select one among the many options available for a feature. The variants and options selected, in turn, may determine the available variants and options for other components and features, because of dependency relations among them. This paper describes and classifies common dependency relations among features and components, extends the ODMG data model to support such a data model, describes a graphical notation for representing the data model, and discusses several useful applications based on the data model that assist the customer in selecting these options and variants.
