    Measurement and metrics in model driven software development Measurement and metrics in model driven software development Presentation Transcript

    • Measurement and Metrics in Model Driven Software Development A short survey research Ahmet Selman Bozkır
    • Today Introduction “A Model-driven Measurement Approach” “Measuring Model Transformation in Model Driven Development” Conclusion
    • Intro Model driven software development is a kind of new concept after object oriented approach in software development field. Model Driven Engineering (MDE) is an approach to software development that advocates the creation of domain-specific languages (DSLs)
    • Intro DSL is specified with a metamodel, from the point of view of MDE and a program written in a DSL is called a model. To address safety-critical concerns and quality assurance, models need to be measured
    • Intro
    • A Model-driven Measurement Approach A Model-driven Measurement Approach Martin Monperrus, Jean-Marc Jezequel, Joel Champeau and Bridgette Hoeltze ACM/IEEE 11th International Conference on Model Driven Engineering Languages 2008
    • A Model-driven Measurement Approach Is it possible? To generate measurement software from an abstract and declarative specification of metrics?
    • A Model-driven Measurement Approach They named their contribution as model-driven measurement approach It specifies metrics as instance of metric specification meta-model and then these metric specifications are used to generate a complete measurement software
    • A Model-driven Measurement Approach Core Contributions: -it measures models of a model-driven development process -it uses models as unique and consistent metric specifications (metric specification metamodel) -it serves application & domain independent measurement
    • A Model-driven Measurement Approach Figure: Model-driven measurement: actions and artifacts The, MSM is used to generate the measurement software itself. (fully automated)
    • A Model-driven Measurement ApproachDerivedMetricSpecification: arithmetic and function based metrics.CollectionBasedDerivedMetricSpecification: high order metrics. Statistical operators.Predicate: is a function from the set of model elements to the truth values.SigmaMetric: is the count of model elements that satisfy a predicate. Predicate can be ascomplex as needed.TauMetric: is the count of model links (i.e: link between two model elements)
    • A Model-driven Measurement Approach A metric specification starts with; - declaration of its type - a mandatory identifier - optional description
    • A Model-driven Measurement Approach
    • A Model-driven Measurement ApproachA Case Study:Maritime Surveilliance System-16 domain metrics implemented- took 1 week (1 day for metrics, 4 days to solve bugs in the measurementsoftware generator prototype)-for comparision – agent based similator took several months-it reduces the development cost of by an order by magnitude(involves creation of domain metamodel from scratch)
    • A Model-driven Measurement Approach
    • Measuring Model Transformation in Model-driven Development Motoshi Saeki and Haruhiko Kaiya (Tokyo Institute of Tech.) Proceedings of the CAiSE 2007 2007
    • Measuring Model Transformation in Model-driven DevelopmentHow to identify what transformation can show theimprovement of the model quality?How to define metrics for model transformation?
    • Measuring Model Transformation in Model-driven Development• In MDD, model transformation is one the most importantsteps.• If a metrics value can express the quality of a model, apositive increasing the metrics vales during thetransformation process can present the model quality.•For this, the formal definition of a transformation mustcover the definition of metrics of model quality in order tocalculate.
    • Measuring Model Transformation in Model-driven DevelopmentContribution:Use a meta modeling method to describe model-specificmetrics.Develop a graph rewriting system to formalize modeltransformation.
    • Measuring Model Transformation in Model-driven DevelopmentTechnique:•Adopt a class diagram of UML to specify meta models•Use Object Contraint Language (OCL) for constraints onmodels.
    • Measuring Model Transformation in Model-driven DevelopmentTechnique:• Embed metrics and their calculation methods into a meta model
    • Measuring Model Transformation in Model-driven Development
    • Measuring Model Transformation in Model-driven Development
    • Measuring Model Transformation in Model- driven Development•Authors propose the technique to specify the metrics ofmodel transformations based on graph rewriting systems•Authors state the importance of collecting usefuldefinitions of metrics. Furthermore, evaluation ofthese metrics is also a good future direction.
