Understanding domains, projector and events.

[Batisska]

I have a repair domain and a project management domain.

When the repair of technical equipment begins, I create the essence of repairs, projects and tasks. I am calling an event from the repair domain to create projects from the projects domain and link them. After the repair is complete, I also close all projects and use project completion events from the projects domain.

Can you tell me if I correctly understood the essence of this part of the event sourcing?
