A modeling paradigm for MDE is considered effective if its models make sense from the point of view of a user that is familiar with the domain, and if they can serve as a basis for implementing systems. The models implementing domain driven design ebook pdf developed through extensive communication among product managers, designers, developers and users of the application domain.
As the models approach completion, they enable the development of software and systems. This abstraction promotes simpler models with a greater focus on problem space. Combined with executable semantics this elevates the total level of automation possible. This page was last edited on 23 October 2017, at 05:29. This requires mappings and transformations and should be modeled too.
Automated tools generally perform this translation. Implementations come from private companies or open source groups. Model-driven architecture does not refer to the architecture of the system being modeled, but rather to the architecture of the various standards and model forms that serve as the technology basis for MDA. UML profile used when MDA was born. The action language for fUML is ALF. As a consequence, the research community uses MDE to refer to general model engineering ideas, without committing to strict OMG standards.
OMG focuses Model-driven architecture on forward engineering, i. ADM decodes to Architecture-Driven Modernization. The objective of ADM is to produce standards for model-based reverse engineering of legacy systems. As the concepts and technologies used to realize designs and the concepts and technologies used to realize architectures have changed at their own pace, decoupling them allows system developers to choose from the best and most fitting in both domains. The OMG documents the overall process in a document called the MDA Guide.
Basically, an MDA tool is a tool used to develop, interpret, compare, align, measure, verify, transform, etc. A tool used to check models for completeness, inconsistencies, or error and warning conditions. Also used to calculate metrics for the model. A tool used to transform models into other models or into code and documentation. A tool used to simulate the execution of a system represented by a given model. This is related to the subject of model execution.
A tool intended to transform particular legacy or information artifact portfolios into full-fledged models. Some tools perform more than one of the functions listed above. For example, some creation tools may also have transformation and test capabilities. There are other tools that are solely for creation, solely for graphical presentation, solely for transformation, etc. In some cases however the parameters may be taken outside the MDA space like in model to text or text to model transformation tools. Eclipse foundation is also developing other tools of various profiles as GMT.
Eclipse’s compliance to OMG specifications is often not strict. This is true for example for OMG’s EMOF standard, which Eclipse approximates with its ECORE implementation. More examples may be found in the M2M project implementing the QVT standard or in the M2T project implementing the MOF2Text standard. This distinction can be made more general by distinguishing ‘variable metamodel tools’ and ‘fixed metamodel tools’. On the contrary, other tools have internal generic capabilities allowing them to adapt to arbitrary metamodels or to a particular kind of metamodels. MDA vendors have been reluctant to engineer their MDA toolsets to be interoperable. Such an outcome could result in vendor lock-in for those pursuing an MDA approach.
