Abstract factory design pattern
The Abstract Factory is a creational design pattern that provides an interface for creating families of related objects without specifying their concrete classes.
Software Design for Python Programmers
The Abstract Factory Design Pattern is a creational design pattern that provides an interface for creating families of related objects without specifying their concrete classes.
- How it is used
- Models run-time creation of coordinated object families while keeping clients independent of concrete construction details.
- How deep it goes
- Explains the definition, roles, Python implementation, concrete products, architecture diagram, and contrast with Factory Method.
- Examples
- Uses varsity and intramural athletics, player strategies, venues, sports, factories, departments, diagrams, and Python listings.
- What you can do after
- Apply it via Python by defining an abstract factory, implementing family-specific factories, and injecting the selected factory into clients.

Object-Oriented Software Design in C++
A creational design pattern that provides an interface for creating families of related or dependent objects without specifying their concrete classes.
- How it is used
- Prevents clients from mixing objects that belong to different product families during runtime construction.
- How deep it goes
- Explains the definition, roles, applied class structure, and concrete object flow, but does not detail implementation beyond the example.
- Examples
- Uses varsity and intramural sports, player strategies, venues, factories, department clients, class diagrams, and C++ listings.
- What you can do after
- Apply it by defining a factory interface, implementing one factory per family, and passing the selected factory to clients or products.

Build AI-Enhanced Web Apps
A creational design pattern that provides an interface for creating families of related objects without specifying their concrete classes.
- How it is used
- Uses one generation interface to switch among language-model providers and models.
- How deep it goes
- Explains the specification, factory roles, and stateless-function alternative, but omits detailed client configuration.
- Examples
- Demonstrates generateText with OpenAI and Anthropic models using provider packages.
- What you can do after
- Apply it via the Vercel AI SDK to replace providers or models without changing client generation code.
