Mda introduction and common research problems
1 like521 views
This document discusses Model Driven Architecture (MDA) and commonly researched problems related to MDA. It provides an introduction to MDA, outlining its model-centric approach and how it aims to address traditional software development problems. Commonly researched problems with MDA include how to evaluate UML for practical use, developing domain-specific modeling languages, model transformation, meta-model evolution, and applying MDA within agile practices. The document concludes that MDA provides benefits like increased productivity but also challenges like rigidity, and identifies areas for further MDA research.
Mda introduction and common research problems
- 1. Model Driven Architecture (MDA) An Introduction and Commonly Research Problems Ha Lai Duy Østfold University College October 19, 2011
- 2. Outline An Introduction Commonly Research Problems Conclusions
- 3. Overview about MDA Model driven architecture: was launched by the OMG in 2001. Model-centric approach: models are the main focus of the software process.
- 4. Traditional Software Development problems Most of the artifacts during the first three phases is just paper and nothing more. Productivity Maintenance Document Portability
- 5. MDA development process The artifacts are formal models (which can be understood by computers) Models are the core at MDA
- 6. Model, Language, and System
- 7. MDA models Platform Independent Model (PIM) a high level abstraction. independent of any implementation technology. Platform Specific Model (PSM) tailored to specify system in terms of the implementation. Code final artifacts in the development
- 9. Meta-model A meta-model is simply a model of a modeling language. It defines the structure, semantics, and constraints for a family of models.
- 11. Transformation Transformation is the automatic process to transform a set of source models to a set of target model. Model to text: Visitor, template. Model to model: OMG’s QVT specification in 2008.
- 12. The Complete MDA Framework M3 MOF is is written written in in QVT is written M2 in UML Transformation ERD Profiles definition Profiles defines M1 Class Transform to Relational diagram diagram
- 13. Outline An Introduction Commonly Research Problems Conclusions
- 14. Commonly Research Problems Model Transformation Metamodelling Apply MDA
- 15. Model research field Evaluate the essential of UML in practice. Due to its complexity & power. Like 3GLs, it does not fit to model specific domain problems.
- 16. Model research field Domain Specific Language (DSL) Propose the modeling language for specific domains e.g. ERD, EBNF, XML Schema, Ontology language,... Buid the model-based DSL framework to take the advantage of MDA features e.g. code generation, transformation… Support to develop a new DSL language in both notation and textual ways.
- 17. Model research field Model operation Support version control system: Models comparision. Conflict detection and resolution. Copy-paste-merge operations. Model validation Debuging model Model query Model transaction
- 18. Transformation research field Exploring possibilities and eliciting requirements. Implement the QVT standard. Evaluate in practical applications.
- 19. Transformation research field Model interpretation vs. code generation Pros: It enables faster changes. It enables changes at runtime. Easier to update and scale. Cons: Customers could not choose their execution environment. We have the freedom at the model aspect, but we left the freedom at the generator rules.
- 20. Metamodelling research field The evolution of the meta-models: Transformation defination should be changed to adapt with new meta-model. Model is invalid with the new version of meta-model. Co-evolution approaches.
- 21. Apply MDA in practice Software development approaches: Agile MDA. MDA framework introduces some risks: It is too rigid: requirement team should understand what is allowed and what is not. The roles is changed in MDA approaches. Enviroment for MDA Education. Culture gap.
- 22. Outline An Introduction Commonly Research Problems Conclusions
- 23. Conclusions Advantages: Gain of productivity. High level of abstraction. Documentation. Maintaining. ... Disadvantages: Rigidity. Require the new roles in software development. Not fully implementation. Does not support version control for collaboration.
- 24. Conclusions Problem statements: The rigidtity of MDA: When request of change comes: Going back and modify the meta-models Effect to other artifacts e.g. models Hack the code: Not well documented maintaning. Manipulating the source models to make it procudes desire result. Models are not truly reflected to the problem domain.
