Abstract
A technique used in a relational database management system that provides a topology data model in which topological elements are stored in topology element tables. The technique allows topological elements to be added to the topology element tables while a feature specifier that represents a feature composed of the topological elements is being defined in the topology data model. The feature specifiers are inserted into fields of a feature column in a feature table. The features belonging to a given feature table define a feature layer. A feature layer may have a child feature layer, and in addition to representing a set of topological elements, a feature specifier may represent a set of features belonging to a child feature layer.
