What is Responsibility?
In software design, responsibility refers to the concept of assigning specific tasks or functions to different parts of the system. In CQRS, responsibility is segregated between the command side and the query side.
- The command side is responsible for handling commands and updating the write model (the part of the system that stores data for write operations)/
- While the query side is responsible for handling queries and providing data from the read model (the part of the system that stores data for read operations).
Full Form of CQRS
CQRS stands for Command Query Responsibility Segregation. CQRS is a software architectural pattern that separates the operations that read data (queries) from the operations that modify data (commands) into different models.
- With CQRS, you have separate models for reads and writes, each optimized for its specific purpose.
- This separation allows you to scale and optimize each model independently, as they have different requirements.
- For example, the read model can be optimized for fast and efficient queries, while the write model can focus on ensuring data consistency and integrity.
