Designing a Flexible and Portable Software System | The Importance of a Platform-Independent Model (PIM)

What is a platform-independent model(PIM)?(a) A software platform before a commitment is made to 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 (b) A precise model of the software architecture before a commitment is made to a specific platform

The correct answer is (b) A precise model of the software architecture before a commitment is made to a specific platform.

A platform-independent model (PIM) refers to a software model that captures the architecture and design of a software system without being bound to any specific hardware or software platform. It is typically created during the early stages of software development when decisions regarding the platform have not yet been finalized.

The purpose of a PIM is to provide a high-level, abstract representation of the software system’s structure, behavior, and interactions. It allows software designers and architects to focus on the fundamental design decisions and functional requirements without being restricted by the limitations or constraints of a particular platform.

A PIM serves as a blueprint for the software and enables communication and collaboration among different stakeholders involved in the software development process. It helps to ensure that the software system is designed with clarity, flexibility, and portability.

Once the PIM has been established, it can be used as a basis for creating platform-specific models (PSMs) that map the software architecture to a specific platform. These PSMs provide the necessary details and adaptations required to implement the software system on a chosen hardware or software platform.

In summary, a platform-independent model (PIM) is a precise and abstract representation of the software architecture before a commitment is made to a specific platform. It assists in designing a software system without being limited by platform-specific details.
