Creational Design Patterns in Modern C++ - Using the Factory Method

The video tutorial discusses the limitations of using macros and conditional statements for creating database instances, leading to tightly coupled and inflexible code. It introduces the factory method design pattern to decouple the client code from specific database classes. The implementation of the factory method is detailed, highlighting its benefits in creating instances without depending on concrete types. However, the method's limitation in ensuring consistent database instances is noted. To address this, the abstract factory design pattern is introduced, which allows for creating instances from a specific database set, ensuring consistency and flexibility.
