Event Sourcing is an approach to software development where all changes to the state of an application are stored as a sequence of events. This sequence of events is called the event log.
There are many benefits to using Event Sourcing, including:
All changes to the state of the application are stored in the event log, which makes it easy to debug issues and track changes.
The event log can be used to replay the events and recreate the state of the application, which is useful for testing and development purposes.
Event Sourcing can be used to implement undo/redo functionality.
The event log can be used to generate reports and analytics.
CQRS is an approach to software development that separates the read and write operations of an application into two separate models.
There are many benefits to using CQRS, including:
Read and write operations can be scaled independently, which can improve performance.
Read and write models can be implemented using different technologies, which can improve flexibility.
CQRS can simplify the development of complex applications.
Event Sourcing + CQRS is an approach to software development that combines the benefits of Event Sourcing and CQRS.
