Command and Query Responsibility Segregation (CQRS) pattern

With the dashboard development in action, now is a good time to look at CQRS design pattern. CQRS stands for “The Command and Query Responsibility Segregation” (CQRS) pattern. This design pattern separates read and update operations for a data store. In a traditional architecture, the same model is used to query and update database. That works for basic CRUD operations. In complex applications, we will end up creating more spaghetti code. A good use case is for dashboards where application has to restrict certain secure data based on user roles or add more complex joins based on a super users permissions. Implementing CQRS in these applications can maximize their performance, scalability, security and most importantly makes them flexible to better evolve over time.

Following is great article that went in depth about the CQRS design pattern:
