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 jruri 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. 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.
A Platform-Independent Model (PIM) in software engineering is a model of a software system or business system, that is independent of the specific technological platform used to implement it.
foe example using PHP DATA OBJECT ( PDO) in php language for model this maks you able to connect with different technologies such as MSsql , mysql , oracle , etc .. without needing to depend on spastic sql query for specific database technology
