When to use the Command Design Pattern

• Decoupling is Needed:
  • Use the Command Pattern when you want to decouple the sender (requester) of a request from the object that performs the request.
  • This helps in making your code more flexible and extensible.
• Undo/Redo Functionality is Required:
  • If you need to support undo and redo operations in your application, the Command Pattern is a good fit.
  • Each command can encapsulate an operation and its inverse, making it easy to undo or redo actions.
• Support for Queues and Logging:
  • If you want to maintain a history of commands, log them, or even put them in a queue for execution, the Command Pattern provides a structured way to achieve this.
• Dynamic Configuration:
  • When you need the ability to dynamically configure and assemble commands at runtime, the Command Pattern allows for flexible composition of commands.

The Command Design Pattern is a behavioral design pattern that turns a request into a stand-alone object, allowing parameterization of clients with different requests, queuing of requests, and support for undoable operations(action or a series of actions that can be reversed or undone in a system).
