{{Short description|Model of a software or business system}}
A '''platform-specific model''' is a model of a software or business system that is linked to a specific technological platform (e.g. a specific [[programming language]], [[operating system]], [[document file format]] or [[database]]). Platform-specific models are jruriindispensable for the actual implementation of a system.

For example, if a needbusiness needs to implement an online shop., then their Thesoftware system will need to store informationdifferent regardingkinds users,of information: available goods, user info such as credit cards, etc. The designer might decide to use for this purpose an [[Oracle database]]. For this to work, the designer will need to express concepts (e.g. the concept of a user) in a [[relational model]] using the [[Oracle database|Oracle]]'s [[SQL]] dialect. This [[Oracle database|Oracle]]'s specific [[relational model]] is an example of a ''Platform-specific model''.

In [[Model-driven architecture]], a platform-specific model is where the design of the model is constructed with the intended execution-platform driving design choices.<ref>{{cite book |url=https://www.google.com/books/edition/Software_Architecture/Xi-JoWzVF54C?hl=en&gbpv=1&dq=%22Platform-specific+model%22+-wikipedia&pg=PA76&printsec=frontcover |title=Software Architecture |first=Flavio |last=Oquendo |page=76 |date=2004}}</ref>

The term ''platform-specific model'' is most frequently used in the context of the [[model-driven architecture|MDA]] approach. This '''MDA''' approach corresponds the [[Object Management Group|OMG]] vision of [[Model Driven Engineering]]. The main idea is that it should be possible to use a [[Model Transformation Language|MTL]] to transform a [[Platform-independent model]] into a Platform-specific model. In order to achieve this transformation, one can use a language compliant to the newly defined [[QVT]] standard. Examples of such languages are [[AndroMDA]], [[VIATRA]] or [[ATLAS Transformation Language|ATL]].
