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
A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language.

In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases ...
). Platform-specific models are indispensable for the actual implementation of a system.
For example, a need to implement an online shop. The system will need to store information regarding users, goods, credit cards, etc. The designer might decide to use for this purpose an
Oracle database
Oracle Database (commonly referred to as Oracle DBMS, Oracle Autonomous Database, or simply as Oracle) is a multi-model database management system produced and marketed by Oracle Corporation.
It is a database commonly used for running online ...
. 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's
SQL dialect. This
Oracle's specific
relational model is an example of a ''Platform-specific model''.
The term ''platform-specific model'' is most frequently used in the context of the
MDA approach. This MDA approach corresponds the
OMG vision of
Model Driven Engineering. The main idea is that it should be possible to use a
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
ATL.
