The unstructured markup means that anything can be stored anywhere. Notations for conceptual modeling of entity relationship diagrams have been extended with notation for aggregation, which satisfy the nesting of structures in aggregate oriented databases [11]. Conceptual modeling of ER-diagrams [5,27] has the benefit that a generic diagram of the whole database is sufficient for moving forward to a design activity, while conceptual modeling of aggregate oriented databases has established a notation for modeling [2]. However the model is specific and not generic. Solutions that prefer a different nesting needs a separate aggregate data model. Our approach to conceptual modeling does not violate the existing relational constraints and provides an extra conceptual layer where documentstructure can be modeled by color coding. We will show that modeling decisions can readily be made and materialize...
