MDA and approach
In computing, online analytical processing, or OLAP (), is an approach to swiftly answer multi-dimensional analytical ( MDA ) queries.
The term platform-specific model is most frequently used in the context of the MDA approach.
Model Driven Architecture ( MDA ) is a software design approach for the development of software systems.
Executable UML is another specific approach to implement MDA
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.
Some key concepts that underpin the MDA approach ( launched in 2001 ) were first elucidated by the Shlaer-Mellor method during the late 1980s.
Indeed a key absent technical standard of the MDA approach ( that of an action language syntax for Executable UML ) has been bridged by some vendors by adapting the original Shlaer-Mellor Action Language ( modified for UML ).
However during this period the MDA approach has not gained mainstream industry acceptance ; with the Gartner Group still identifying MDA as an " on the rise " technology in its 2006 " Hype Cycle ", and Forrester Research declaring MDA to be " D. O. A.
Potential concerns that have been raised with the OMG MDA approach include:
* Incomplete Standards: The MDA approach is underpinned by a variety of technical standards, some of which are yet to be specified ( e. g. an action semantic language for xtUML ), or are yet to be implemented in a standard manner ( e. g. a QVT transformation engine or a PIM with a virtual execution environment ).
* Vendor Lock-in: Although MDA was conceived as an approach for achieving ( technical ) platform independence, current 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.
* Idealistic: MDA is conceived as a forward engineering approach in which models that incorporate Action Language programming are transformed into implementation artifacts ( e. g. executable code, database schema ) in one direction via a fully or partially automated " generation " step.
Evidence that the full MDA approach may be too idealistic for some real world deployments has been seen in the rise of so-called " pragmatic MDA ".
* OMG Track Record: The OMG consortium who sponsor the MDA approach ( and own the MDA trademark ) also introduced and sponsored the CORBA standard which itself failed to materialise as a widely utilised standard.
Thus an application that has been successfully developed via a pure MDA approach could theoretically be ported to a newer release. NET platform ( or even a Java platform ) in a deterministic manner – although significant questions remain as to real-world practicalities during translation ( such as user interface implementation ).
Regardless, adopters of MDA who are seeking value via an " alternative to programming " should be very careful when assessing this approach.
The complexity of any given problem domain will always remain, and the programming of business logic needs to be undertaken in MDA as with any other approach.
MDA and OMG

MDA and vision
This aligns with OMG's vision that MDA should allow modelling of a problem domain's full complexity in UML ( and related standards ) with subsequent transformation to a complete ( executable ) application.
* Uncertain Value Proposition ( UVP ): As discussed, the vision of MDA allows for the specification of a system as an abstract model, which may be realized as a concrete implementation ( program ) for a particular computing platform ( e. g.. NET ).

MDA and Engineering
