Model Driven Architecture


Mda definition l.jpg

Model Driven Architecture - The OMG approach for specifying system as models separate from their implementations, for specifying implementation, and for transforming models into implementations. This is based on a set of standards for describing business and application logic in a machine-readable, technology-independent way. The standards include MOF, UML, OCL, QVT and XMI.

MDA Definition


Mda marketing l.jpg
MDA Marketing system as models separate from their implementations, for specifying implementation, and for transforming models into implementations. This is based on a set of standards for describing business and application logic in a machine-readable, technology-independent way. The standards include MOF, UML, OCL, QVT and XMI.

  • “These (MDA) specifications will lead the industry towards interoperable, reusable, portable software components and data models based on standard models.” - MDA Guide Version 1.01, www.omg.org/docs/03-06-01.pdf

  • “Model-driven engineering technologies offer a promising approach to address the inability of third-generation languages to alleviate the complexity of platforms and express domain concepts effectively.” - Douglas C. Schmidt, in IEEE Computer, February 2006


Mda a specialization of mde l.jpg
MDA: A specialization of MDE system as models separate from their implementations, for specifying implementation, and for transforming models into implementations. This is based on a set of standards for describing business and application logic in a machine-readable, technology-independent way. The standards include MOF, UML, OCL, QVT and XMI.


Mde concepts l.jpg
MDE Concepts system as models separate from their implementations, for specifying implementation, and for transforming models into implementations. This is based on a set of standards for describing business and application logic in a machine-readable, technology-independent way. The standards include MOF, UML, OCL, QVT and XMI.

  • Models and Meta-Models

  • Domain Specific Languages

  • Transformations


Models and meta models l.jpg
Models and Meta-Models system as models separate from their implementations, for specifying implementation, and for transforming models into implementations. This is based on a set of standards for describing business and application logic in a machine-readable, technology-independent way. The standards include MOF, UML, OCL, QVT and XMI.

  • Models give a high-level, problem-oriented view , rather than a low-level, solution-oriented view of systems

  • Meta-Models are used to describe Models in a precise, machine-translatable way


Domain specific language dsl l.jpg

(Wikipedia) A programming language designed to be useful for a specific set of tasks. This is in contrast to general-purpose programming language (general-purpose language, GPL), for example Java or C#, or general-purpose modeling languages like UML. Examples of DSLs include spreadsheet macros, YACC for parsing and compilers, Csound, a language used to create audio files, and GraphViz, a language used to define directed graphs, and create a visual representation of that graph.

DSLs have also been called by various names:

Little languages

Macros (in reference to the macro feature found in many applications)

Application languages

Very high level languages

Domain Specific Language (DSL)


Mda definitions l.jpg
MDA Definitions for a specific set of tasks. This is in contrast to general-purpose programming language (general-purpose language, GPL), for example Java or C#, or general-purpose modeling languages like UML. Examples of DSLs include spreadsheet macros, YACC for parsing and compilers, Csound, a language used to create audio files, and GraphViz, a language used to define directed graphs, and create a visual representation of that graph.

  • MDA – Model-driven architecture, a platform for abstracting system details in a machine-readable format [1]

  • Models and Meta-models

    • CIM – Computation Independent Model

      • “Domain Model” – business-level view

    • PIM – Platform Independent Model

    • PSM – Platform Specific Model

  • UML-based (defined by MOF)

  • Machine-readable (XMI)

  • Documented standards


Mda definitions 2 l.jpg
MDA Definitions (2) for a specific set of tasks. This is in contrast to general-purpose programming language (general-purpose language, GPL), for example Java or C#, or general-purpose modeling languages like UML. Examples of DSLs include spreadsheet macros, YACC for parsing and compilers, Csound, a language used to create audio files, and GraphViz, a language used to define directed graphs, and create a visual representation of that graph.

  • UML – Unified Modeling Language

  • OCL – Object Constrain Language

  • MOF – Meta Object Facility

  • XMI - XML Metadata Interchange

  • QVT – Query, View, Transformation


Mof a dsl for dsl s l.jpg
MOF: A DSL for DSL's for a specific set of tasks. This is in contrast to general-purpose programming language (general-purpose language, GPL), for example Java or C#, or general-purpose modeling languages like UML. Examples of DSLs include spreadsheet macros, YACC for parsing and compilers, Csound, a language used to create audio files, and GraphViz, a language used to define directed graphs, and create a visual representation of that graph.

  • MOF can be viewed as a domain language for describing language

  • OMG has used the MOF to define UML, a domain language for graphical modeling of systems

  • This gives UML a precise, machine-readable and translatable definition, for which tool support can be provided

  • The intent of MOF is to allow the precise definition of DSL's by its users


The mda meta model hierarchy l.jpg
The MDA (Meta-)Model Hierarchy for a specific set of tasks. This is in contrast to general-purpose programming language (general-purpose language, GPL), for example Java or C#, or general-purpose modeling languages like UML. Examples of DSLs include spreadsheet macros, YACC for parsing and compilers, Csound, a language used to create audio files, and GraphViz, a language used to define directed graphs, and create a visual representation of that graph.


From models to models l.jpg
From Models... to Models for a specific set of tasks. This is in contrast to general-purpose programming language (general-purpose language, GPL), for example Java or C#, or general-purpose modeling languages like UML. Examples of DSLs include spreadsheet macros, YACC for parsing and compilers, Csound, a language used to create audio files, and GraphViz, a language used to define directed graphs, and create a visual representation of that graph.

  • Query, View, Transformation (QVT)

  • Takes a Model and a Mapping as inputs, produces a lower level model as output

  • Example: Given a CIM and a mapping to a PIM design model, a transformation produces a PIM design model for that CIM


From models to artifacts code l.jpg
From Models to Artifacts (Code) for a specific set of tasks. This is in contrast to general-purpose programming language (general-purpose language, GPL), for example Java or C#, or general-purpose modeling languages like UML. Examples of DSLs include spreadsheet macros, YACC for parsing and compilers, Csound, a language used to create audio files, and GraphViz, a language used to define directed graphs, and create a visual representation of that graph.

  • With sufficiently detailed PSMs and Platform models, it is possible to generate code and configuration files for environments such as J2EE and .NET

  • The OMG MDA specification doesn't have anything specific on this topic

  • Other MDE systems use a variety of technologies, usually called 'model compilers' or 'generators'


Xmi xml metadata interchange l.jpg
XMI – XML Metadata Interchange for a specific set of tasks. This is in contrast to general-purpose programming language (general-purpose language, GPL), for example Java or C#, or general-purpose modeling languages like UML. Examples of DSLs include spreadsheet macros, YACC for parsing and compilers, Csound, a language used to create audio files, and GraphViz, a language used to define directed graphs, and create a visual representation of that graph.

  • (Wikipedia) The XML Metadata Interchange (XMI) is an OMG standard for exchanging metadata information via Extensible Markup Language (XML). It can be used for any metadata whose metamodel can be expressed in Meta-Object Facility (MOF). The most common use of XMI is as an interchange format for UML models, although it can also be used for serialization of models of other languages (metamodels).


References l.jpg
References for a specific set of tasks. This is in contrast to general-purpose programming language (general-purpose language, GPL), for example Java or C#, or general-purpose modeling languages like UML. Examples of DSLs include spreadsheet macros, YACC for parsing and compilers, Csound, a language used to create audio files, and GraphViz, a language used to define directed graphs, and create a visual representation of that graph.
