Platform Specific Model (PSM) is a model in software engineering that specifies the design of a system for a particular platform or technology. It is an implementation of the Platform Independent Model (PIM), which is a technology-independent model used to describe the system design.

The purpose of a PSM is to provide a detailed blueprint for how a software system will be built on a particular platform. It contains information about the hardware, software, and operating system that will be used to develop the system. PSMs are typically created after the PIM has been developed and can be used to generate code for a specific platform.

The components of a PSM may include platform-specific code, libraries, and configuration settings. PSMs can also include details about the user interface, database design, and other system components.

The importance of a PSM is that it helps ensure that the system is designed and implemented in a way that is appropriate for the chosen platform. It can also help reduce development time and costs by providing a more efficient way to develop software for a specific platform.

One of the benefits of using a PSM is that it can simplify the development process by providing a pre-defined structure for the system. This can help reduce the time and effort required to develop software and can help ensure that the system is designed in a way that is consistent with industry best practices.

However, a potential disadvantage of using a PSM is that it can limit flexibility in terms of the platforms on which the system can be deployed. If the system needs to be deployed on a different platform, significant changes may be required to the PSM, which can increase development time and costs.

An example of a PSM is the Android platform-specific model, which specifies how a software system will be built on the Android operating system. It includes details about the Android software development kit (SDK), user interface components, and other platform-specific details.
