Model driven architecture Wikipedia. Model driven architecture MDA is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. Model driven architecture is a kind of domain engineering, and supports model driven engineering of software systems. It was launched by the Object Management Group OMG in 2. OvervieweditThe model driven architecture approach defines system functionality using a platform independent model PIM using an appropriate domain specific language DSL. Then, given a platform model corresponding to CORBA,. NET, the Web, etc., the PIM is translated to one or more platform specific models PSMs that computers can run. This requires mappings and transformations and should be modeled too. The PSM may use different DSLs or a general purpose language. Automated tools generally perform this translation.

Implementations come from private companies or open source groups. MDA principles can also apply to other areas such as business process modeling BPM where the PIM is translated to either automated or manual processescitation needed. Related standardseditThe MDA model is related to multiple standards, including the Unified Modeling Language UML, the Meta Object Facility MOF, XML Metadata Interchange XMI, Enterprise Distributed Object Computing EDOC, the Software Process Engineering Metamodel SPEM, and the Common Warehouse Metamodel CWM. Note that the term architecture in 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. Executable UML was the UML profile used when MDA was born. Now, the OMG is promoting f. UML, instead. The action language for f. UML is ALF. TrademarkeditThe Object Management Group holds registered trademarks on the term Model Driven Architecture and its acronym MDA, as well as trademarks for terms such as Model Based Application Development, Model Driven Application Development, Model Based Application Development, Model Based Programming, Model Driven Systems and others. The main acronym that has not yet been deposited by OMG until now is Model driven engineering MDE. As a consequence, the research community uses MDE to refer to general model engineering ideas, without committing to strict OMG standards. Model driven architecture topicseditMDA approacheditOMG focuses Model driven architecture on forward engineering, i. OMGs ADTF Analysis and Design Task Force group leads this effort. With some humour, the group chose ADM MDA backwards to name the study of reverse engineering. ADM decodes to Architecture Driven Modernization. The objective of ADM is to produce standards for model based reverse engineering of legacy systems. Knowledge Discovery Metamodel KDM is the furthest along of these efforts, and describes information systems in terms of various assets programs, specifications, data, test files, database schemas, etc. One of the main aims of the MDA is to separate design from architecturecitation needed. 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. DevOps is an approach to lean and agile software delivery that promotes closer collaboration between lines of business, development and IT operations. Historically.

The design addresses the functional use case requirements while architecture provides the infrastructure through which non functional requirements like scalability, reliability and performance are realized. MDA envisages that the platform independent model PIM, which represents a conceptual design realizing the functional requirements, will survive changes in realization technologies and software architectures. Of particular importance to model driven architecture is the notion of model transformation. Drop Rac Database Manually on this page. A specific standard language for model transformation has been defined by OMG called QVT. MDA toolseditThe OMG organization provides rough specifications rather than implementations, often as answers to Requests for Proposals RFPs. The OMG documents the overall process in a document called the MDA Guide. Modeldriven architecture MDA is a software design approach for the development of software systems.

Pega BPM and case management software allows you to build and manage enterpriselevel strategic applications that can communicate with legacy systems. Basically, an MDA tool is a tool used to develop, interpret, compare, align, measure, verify, transform, etc. In the following section model is interpreted as meaning any kind of model e.

In any MDA approach we have essentially two kinds of models initial models are created manually by human agents while derived models are created automatically by programs. For example, an analyst may create a UML initial model from its observation of some loose business situation while a Java model may be automatically derived from this UML model by a Model transformation operation. An MDA tool may be one or more of the following typescitation needed Creation Tool. A tool used to elicit initial models andor edit derived models. Analysis Tool. A tool used to check models for completeness, inconsistencies, or error and warning conditions. Also used to calculate metrics for the model. Transformation Tool. A tool used to transform models into other models or into code and documentation. Composition Tool. A tool used to compose i. Test Tool. A tool used to test models as described in Model based testing. Simulation Tool. A tool used to simulate the execution of a system represented by a given model. This is related to the subject of model execution. Metadata Management Tool. A tool intended to handle the general relations between different models, including the metadata on each model e. Reverse Engineering Tool. 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. One of the characteristics of MDA tools is that they mainly take models e. MOF models or metamodels as input and generate models as outputcitation needed. In some cases however the parameters may be taken outside the MDA space like in model to text or text to model transformation tools. Implementations of the OMG specifications come from private companies or open source groups. One important source of implementations for OMG specifications is the Eclipse Foundation EF. Many implementations of OMG modeling standards may be found in the Eclipse Modeling Framework EMF or Graphical Modeling Framework GMF, the Eclipse foundation is also developing other tools of various profiles as GMT. Eclipses compliance to OMG specifications is often not strict. This is true for example for OMGs EMOF standard, which Eclipse approximates with its ECORE implementation. More examples may be found in the M2. M project implementing the QVT standard or in the M2. T project implementing the MOF2. Text standard. One should be careful not to confuse the List of MDA Tools and the List of UML tools, the former being much broader.
