PIM (Platform Independent Model)

A Platform Independent Model (PIM) is an abstract representation of a software system's design, focusing on its essential features and functionality without considering how or where it will be implemented. Think of it as a blueprint that outlines what the system should do, free from technical details about specific hardware, programming languages, or platforms. This abstraction allows developers to understand and communicate the core concepts clearly, and later adapt or transform the model into specific platform-dependent designs for different environments or technologies.
