I often see cqrs samples  go

Do Something to in memory model .
Persist()
Fire Events;   // in Event Sourcing some events do the  persisting ,..

but doesn't this allow the domain to get out of wack with the database ? eg
what if the model is updated and then the database transaction fails ?

Or do you work with singular roots and only allow another command to use
that once the data is persisted ?

Regards,

Ben

Changes are transient until persisted. If a persist fails the easiest thing
is to evict the ibject from memory though you can support undos
