Difference between CQRS and CQS - Stack Overflow
WEBCQS (Command Query Separation) and CQRS (Command Query Responsibility Segregation) are very much related. You can think of CQS as being at the class or component level, while CQRS is more at the bounded context level.
CQRS pattern - Azure Architecture Center | Microsoft Learn
WEBCQRS stands for Command and Query Responsibility Segregation, a pattern that separates read and update operations for a data store. Implementing CQRS in your application can maximize its performance, scalability, and security.
Command–query separation - Wikipedia
WEBCommand query responsibility segregation (CQRS) generalises CQS to services, at the architectures level: it applies the CQS principle by using separate Query and Command interfaces and usually data models to retrieve and modify data, respectively. [2][3] Other architectural patterns.
Command Query Separation (CQS) - A simple but powerful pattern
WEBYou could say that CQS works more on the method or class level, whilst CQRS takes the concepts of CQS and takes it to the application level. With CQS you separate methods for querying from or writing to a model.

Command Query Separation - Martin Fowler
WEBDec 5, 2005 · Queries: Return a result and do not change the observable state of the system (are free of side effects). Commands: Change the state of a system but do not return a value. Because the term 'command' is widely used in other contexts I prefer to refer to them as 'modifiers', you also see the term 'mutators'.
CQRS (command query responsibility segregation) - TechTarget
WEBCQRS vs. CQS Although related to and inspired by CQS, CQRS is different in that objects are split into two objects: one containing commands and one containing queries. Separate model representations for queries and commands make the approach highly suitable for event sourcing or task-based user interface ( UI ) applications.
CQRS - Martin Fowler
WEBJul 14, 2011 · Using CQRS on a domain that doesn't match it will add complexity, thus reducing productivity and increasing risk. The other main benefit is in handling high performance applications. CQRS allows you to separate the load from reads and writes allowing you to scale each independently.
