Platform-specific model¶
A system-design model whose structure is expressed for a chosen programming, database, operating-system, or other implementation platform.
Core Idea¶
A platform-specific model is a design representation connected to a chosen technological environment. It takes a software or business system concept and expresses it using constructs of a database, programming language, operating system, file format, or another intended implementation platform. In model-driven architecture, that target environment is not an afterthought: it guides the model's design choices.
The frozen online-shop example makes the distinction concrete. A generic notion of user information becomes a particular relational representation using an Oracle SQL dialect. The model is not the running shop or simply a platform-independent sketch with a vendor name attached. Its platform detail supports implementation but also limits direct portability when the execution environment changes.
Scope of Application¶
These uses require a target-system model whose design actually depends on a chosen platform.
- Database design. Expresses business concepts in a chosen relational/database dialect.
- Model-driven architecture. Makes execution-platform assumptions explicit in design choices.
- Implementation handoff. Communicates model structures that can guide realization.
- Portability audit. Identifies commitments that must change when moving to another platform.
Clarity¶
Find the target system, chosen platform, and at least one design structure genuinely dictated by that platform. Inclusion test: The source's shop-user concept becomes an Oracle-specific relational/SQL design used to guide implementation. Exclusion test: A technology-neutral diagram, running code without a model, or a vendor label pasted onto a sketch is not enough. Nearest boundary: Saying only 'use a database' leaves the model platform-independent. A PSM is a representation for intended implementation, not proof that code already exists or that the design moves unchanged to another platform.
Manages Complexity¶
A PSM compresses many implementation constraints into a structured design view, making the target-platform assumptions visible. That reduces ambiguity at handoff but increases coupling to the chosen language, database, or environment; portability must be tested at the construct level, not inferred from the model's name.
Abstract Reasoning¶
- Name the system concept being represented.
- Name the execution or storage platform that constrains design.
- Find a concrete mapping from concept to platform-native structure.
- Check how the model guides implementation without equating it with running code.
- Identify which commitments fail or require translation on a different platform.
Knowledge Transfer¶
The target-to-platform mapping method transfers across chosen databases, languages, and operating environments when each new platform's constructs are specified. An Oracle-oriented relation does not literally become a different database dialect's PSM without remapping; a purely conceptual model lacks the platform-specific differentia.

Neighborhood in Abstraction Space¶
Platform-specific model sits in a crowded region of the domain-specific corpus (35th percentile for distinctiveness): several abstractions share nearly its structure, so a description that fits it tends to fit its neighbors too.
