Behavioral Design Patterns in C++ - Logging System - I

The lecture introduces a project to demonstrate the chain of responsibility pattern. It begins with setting up a project and adding a class to manage application state. A file logger is implemented to log application events. For sensitive events, database logging is added. However, this approach violates design principles like the Open-Closed Principle and Dependency Inversion Principle. The lecture concludes with a plan to refactor the design by introducing a common base class for loggers, aiming to decouple the Winapp class from specific loggers.

Explain how the application handles sensitive data according to the lecture.

What is the purpose of the logger in the application discussed?

How does the application log events to a database?

What principles were violated in the design of the Winapp class?

What changes are proposed to improve the design of the Winapp class?

Describe the relationship between the Filelogger and Dblogger classes.

What is the significance of the pure virtual function in the new class proposed?
