For the past week , I have read about applying the CQRS Pattern in a project . CQRS stands for Command and Query Responsibility Segregation . This design pattern is aimed to segregate the read and update operation in a project .
The CQRS pattern separates read and write into different models , using commands to update data , and queries to read data . The presentation layer for commands is typically separated into Validation , Command , Domain and Persistence . Queries is separated into a read-only layer to generate Data Transfer Objects .
The benefits of using the CQRS pattern is simply like the pattern named itself . The separation of command and query models , resulting in a more simplified design in a project .
However , this design pattern is more suitable for larger projects where the requirements for read and write operations that is more complex and challenging . For simple CRUD operations, we might not need to implement this pattern .
