- idea
- abandoning quantitative minimalism in terms of categories,
- bringing conceptual, logical and physical modeling down to one level,
- the notion of association in the very center of the association-oriented modeling idea,
- principle: one model element should perform one function in the model,
- principle: one operation should refer to one model element,
- abandoning ctitious categories occurring in the conceptual sphere only, e.g. aggregation in object-oriented modeling,
- structure
- categories: collection (Coll), attribute (Attr), object (Obj), association
- (Assoc), role (Role), association-object (AssocObj),
- n-ary relationships established on a physical level,
- comprehensive approach to multiplicity of relationships (multiplicity also in terms of an association),
- descriptions of associations and roles,
- mechanism
- independent role and attribute inheritance,
- new inheritance mode,
- new, unambiguous algorithm for de ning pre xes of attributes and roles, ensuring full access to all components inherited,
