My intuitive recommendation is that you should use seperate representations in the different systems. More flexible and less dependencies between them.
I think it is bad to share db between systems. Each should own it's data, but replication (via message bus) might be needed. Each system can store it's own representation. Only one should be master (responsible for updating data). In ddd terms this is about different bounded contexts and anti-corruption layer. This is absolutely not the only ddd strategic design pattern.
