Creational Design Patterns in Modern C++ - Pros and Cons - highlights the pros and cons of this pattern and when to use

The video tutorial explains the abstract factory design pattern, highlighting its structure, advantages, and disadvantages. It uses a database framework example to illustrate how abstract factories manage object creation without exposing concrete classes. The tutorial compares abstract factory with factory method, emphasizing the creation of related families of classes. It concludes with use cases where abstract factory is beneficial, such as when enforcing consistency among product families.

What is the primary role of a concrete factory in the abstract factory design pattern?

• To expose concrete classes to the client

• To create instances of products from a single family

• To manage the lifecycle of abstract products

• To create instances of products from multiple families

In the database framework example, what is the role of the SQL Factory?

• To create instances of MySQL classes

• To create instances of SQL classes

• To manage database transactions

• To expose concrete database classes to the client

What is one advantage of using the abstract factory design pattern?

• It enforces consistency among products

• It allows mixing classes from different families

• It simplifies the addition of new products

• It promotes tight coupling

What is a disadvantage of the abstract factory design pattern?

• It is difficult to add new products

• It promotes tight coupling

• It simplifies the addition of new configurations

• It allows mixing classes from different families

How does the abstract factory pattern differ from the factory method pattern?

• Abstract factory manages creation of related families

• Factory method creates instances of related families

• Abstract factory creates instances of unrelated classes

• Factory method exposes concrete classes to the client

When should you use the abstract factory design pattern?

• When you need to create instances of unrelated classes

• When you want to expose concrete classes to the client

• When you have families of related classes

• When you need to mix classes from different families

What is a key feature of the abstract factory design pattern?

• It exposes concrete classes to the client

• It uses only one factory at a time

• It creates instances of classes from different sets

• It allows the use of multiple factories simultaneously
