Event Sourcing

Event sourcing is an architectural pattern in which all changes to the state of an application are stored as a sequence of events. These events are immutable facts about actions that have taken place in the past.

Instead of just storing the current state, event sourcing enables a complete reconstruction of the system state at any point in time by replaying the stored events.

• Fundamentals and principles of event sourcing
• Modeling events
• Emitting events
• Loading events
• Event Store: Storage and retrieval of events
• Projections and read models
• Integration with CQRS (Command Query Responsibility Segregation)
• Practical implementation examples

The training is designed to integrate as easily as possible into your daily work routine.

We start each day with a joint video conference in the morning. During the subsequent longer lunch break, you work independently on a work assignment and still have time for emails or other urgent matters. In the afternoon, there is another joint video conference.

This training course is aimed at software developers, architects and technical team leaders who want to learn about modern architectural patterns and apply them in their projects. It is particularly suitable for teams working with complex domains or developing systems with high requirements for auditability and traceability.

Basic programming skills and an understanding of object-oriented concepts are required. Experience with domain-driven design is helpful but not essential.

• You understand event sourcing as a modern architecture strategy
• You can apply event sourcing at the code level
• You understand the connection with CQRS
• You understand the advantages and disadvantages of event sourcing
• You can judge when event sourcing is the right choice
