How to use ORM in DDD

Write model

• Create the event sourced aggregate. The events will be replayed when saving aggregate to the SQL database.
• Create the aggregate repository:
  • Save aggregate: replay events in SQL
    • Event store: append events to event stream (insert into Event select from json...)
    • State store:
      • Without object serialization: Create delete/insert/update SQL statements with Data Commander
      • With object serialization: delete/insert/update from/into table from json...)
  • Get aggregate by id:
    • create SQL statement manually
    • generate C# wrapper with Data Commander
