By what means is an environment created to simulate any processes [C#]?

Question

CRM

How to implement in your project, something like a simulation environment like in Cisco Packet Tracer, for example, or some kind of CRM system. Those. what is the workspace?
It is clear that each object on the workspace is an instance of a specific class that is created automatically when it is transferred to the "workspace", moreover, by the Drag & Drop method (but this is not the most important thing).
How to do the same, how to implement these objects (to begin with) and subsequently the connection between them?

Answer 1

If you want to implement it yourself:
The data structure is a list of trees;
Node - some kind of base class or interface;
List of operations:
- Add / remove / change node;
- Send/receive a message (here a global queue can be used, which receives messages from nodes, and the handler, depending on the address, sends a message to the addressee)
- Search for a node
- Tree traversal to determine the route or search for a node.
I think it is better to store data in a database
. If you don’t need to implement, what you can search on the Internet computer modeling

Answer 2

If a logical decision, then you have already been told above.
