Command Query Responsibility Segregation (CQRS)

Command Query Responsibility Segregation (CQRS) is a design pattern used in software development that separates data modification tasks (commands) from data retrieval tasks (queries). In simpler terms, it means that when you change data—like updating an address—it’s handled differently than when you just want to look up information—like checking a shipping status. This separation can improve performance, scalability, and clarity in applications, allowing developers to optimize each part for its specific purpose without one impacting the other negatively. CQRS is often used in complex systems where efficiency and organization are key.
