3LGM² Meta Model

to describe, evaluate and plan health information systems

• Definition of concepts and their relationships to describe health information systems using UML class diagrams
• Domain layer to describe enterprise functions supported by the information system, and the information processed ( UML diagram of the domain layer)
• Logical tool layer to describe the application components used to support enterprise functions, and the communication between these application components ( UML diagram of the logical tool layer)
• Physical tool layer to describe the hardware components necessary for the operation of the application components ( UML diagram of the physical tool layer)
• Inter-Layer-Relationships to describe interdependencies between concepts of different layers.
