Comparison between CRUD and CQRS in an event driven system

Abstract: In todays digitalised society, effective solutions to manage huge amount of data is needed. An established design pattern that are used in many systems are CRUD. To handle data in events have become more popular over the years, but CRUD is not optimised for it. A possible replacement is CQRS, it is designed with events in mind. The purpose of the report is to see if CQRS can replace CRUD. The report shows that when it comes to an event driven system using event sourcing, CQRS is recommended. Reason being CQRS is more compatible with events then CRUD. CRUD is more designed around data driven design and therefor is a better fit for other systems.
