Isosemantic models
• User interface models– Convenient for data entry– Typically pre-coordinated– Many variations
• Storage models– Only one model is designated as the storage model– Comprehensive set of qualifiers and modifiers– The storage model is referenced in reports, rules,
protocols, data analysis
• Composition – Decomposition mappings
