Final answer:
The three types of abstract system models recommended by the Model-Driven Architecture (MDA) method are a computational-independent model (CIM), a platform-independent model (PIM), and one or more platform-specific models (PSMs).
Step-by-step explanation:
The three types of abstract system models recommended by the Model-Driven Architecture (MDA) method are:
- A computational-independent model (CIM)
- A platform-independent model (PIM)
- One or more platform-specific models (PSMs)
The CIM represents the system in a technology-neutral way, the PIM captures the system's design without platform-specific details, and the PSMs represent the system in a specific platform or technology.
