Optimize: add plantuml diagram

[c5ms]

Why

The existing diagram is created many years ago, and is lack of the package (boundary context) and properties.
So I added the UML diagram with plantuml.

pros:

1. It's easy to maintain.
2. It's more clearly to show the relationship.
3. It's more clearly to show technic concept.

What

• [add] plantuml for domain diagram

[orende]

I think this UML diagram is a good addition, but I don't want it to replace the ER diagram, since the two types of diagram serve different purposes (software architecture for UML and database structure for ER). Can you put this image below the Trello board link in the readme and revert the removal of the ER diagram?

[c5ms]

Sounds good for me, I did it.

What is the purpose of the diagram? Class diagram, context map or something in between?

[c5ms]

The diagram is a class diagram to show the architecture on domain implementation.

1. The Boundary context of the subdomains
2. The relationship between the aggregate roots and value objects

[mackapappa]

I’m not sure I follow you on the bounded contexts.Do you mean that cargo, voyage, handling and location are four different bounded contexts? To me it looks more like a class diagram of classes in the domain layer.

[c5ms]

I was meaning that that the cargo, voyage, handling and location are in the same bounded contexts.
But in this context, they are four different sub-domain and has it's own little context for each aggregate root and it's value objets.And each subdomain has it's design and relationship and interaction with others.
Sorry for confusing you.
