InterSystems Track Relationship between Menus, Workflow, Workflow Items, Questionaire etc

Hi InterSystems Architects,

Please may I know the relationship between 

1. Menus, Workflows, Workflow Items, Components, Code Tables, etc 

Detailed relationship diagrams, how each element in each of the above are related to another. 

2. When I extracted the data. I see ID number, but they aren't unique or related. I wanted to build a relationship between them myself in the absence of documents but I am missing the critical unique primary key of each and how they are referred in another table.

Your help is appreciated and let me know if you need any specific (Non Confidential) information to get help.
