Optimizing Your Software Architecture | Developing a Platform-Specific Model (PSM)

What is a platform-specific model(PSM)?(a) A specific hardware platform.(b) A precise model of the software architecture before a commitment is made to a specific platform.(c) A precise model of the software architecture mapped to a specific platform.(d) A graphical or textual description of the software.

The correct answer is (c) A precise model of the software architecture mapped to a specific platform

The correct answer is (c) A precise model of the software architecture mapped to a specific platform.

A platform-specific model (PSM) is a representation or description of the software architecture that is tailored or mapped to a specific hardware platform. It provides a detailed and specific view of the software, taking into account the characteristics and constraints of the chosen platform.

PSMs are typically developed after a general software architecture has been defined and before the actual development for a specific platform occurs. They help in refining the architecture by considering platform-specific details and constraints. This allows the software to be optimized for a particular platform and ensures that it will effectively utilize its resources and capabilities.

The PSM includes platform-specific technologies, APIs, libraries, components, and other necessary details to support the software’s implementation on the chosen platform. It serves as a blueprint for the development team to precisely understand how the software should be implemented on the specific platform.

By having a platform-specific model, developers can make informed decisions about design choices, performance optimizations, and resource utilization specific to the targeted platform. It also helps in ensuring compatibility and smooth integration with the platform’s ecosystem.

In summary, a platform-specific model (PSM) refers to a precise representation of the software architecture that is specifically tailored and mapped to a particular hardware platform, considering its unique characteristics and constraints.
