CQRS (Command Query Responsibility Segregation)

CQRS, or Command Query Responsibility Segregation, is a design pattern used in software development. It separates the processes of changing data (commands) from those that retrieve data (queries). This distinction allows for optimized performance, as each side can be tuned for its specific purpose. For instance, commands can focus on changing the database efficiently, while queries can be structured for quick data retrieval. This separation also enhances scalability and maintainability, making it easier to adapt and improve different parts of an application without affecting others.
