Using ANSI SQL as a Conceptual Hierarchical Data Modeling
This paper will explain and show how standard ANSI SQL processors can naturally model and automatically process complex multi-leg hierarchical data structures at a full conceptual hierarchical level. This also means the query user does not need to have structure knowledge of the hierarchical structures involved. The data modeling capability includes dynamically combining logical hierarchical relational and physical XML data structures at a full hierarchical level. This also includes the ability to link below the root of the lower level structure intuitively forming a valid unified hierarchical structure. As will be shown, ANSI SQL’s high level hierarchical data processing allows the flexible conceptual control of hierarchical node promotion, fragment processing, structure transformation, and variable structure creation.
