MDA Lifecycle

MDA and Development Processes Agile Agile Minimize documentation X use only documentation Minimize documentation X use only documentation Documents are only created if they are needed Documents are only created if they are needed Extreme programming Extreme programming Development on the code level is not encouraged Development on the code level is not encouraged “Extreme modelling” “Extreme modelling” RUP RUP MDA works together with RUP MDA works together with RUP Many artifacts from the RUP can be used – UML Many artifacts from the RUP can be used – UML A different path for MDA A different path for MDA

MDA Tools Tools are standards based, not proprietary Tools are standards based, not proprietary Integration of modeling and development Integration of modeling and development 70-80% of the structural code can be generated 70-80% of the structural code can be generated Test Cases can be generated from OCL Test Cases can be generated from OCL Many different aspects Many different aspects Archetype patterns Archetype patterns
