• What about an example?
• Two Models in CQRS: Command and Query Models
• How can we ensure consistency?
• Aggregates and consistency rules in Aggregates
• How about Parameter Resolvers?

• Similarities and differences between Sagas and Aggregates
• Sagas in Axon vs. Saga database patterns - the new name for Sagas in Axon 
• Managing complex business processes
• Annotations for Saga
• Test fixtures for Sagas in Axon Framework
• Some things to keep in mind when using Sagas
