What are the rudimentary types of information connectivity i.e. model types?

I am looking at a modelling tool and are trying to determine all the types of ways that you can model (at a rudimentary level)

I remember seeing a list of ways in which you can connect or categorise information elements. basically the types were as follows:

-
Lists - constitute a list of information elements

-
Hierarchies- visualise information in a parent-child relationship (ie organisational chart)

-
Flows - connect elements in a logical (lateral) flow (ie process model)

Have you seen any reference to these types, or can you elaborate on the full list of "model types"

Model theory, branch of mathematical logic, is based on three things: atoms, functions, and relations. With these you can define pretty much anything. In fact, functions are subsumed by relations, so you only need two.

What is a list but a next relation? What is a hierarchy but a parent-child relation?

Of course these satisfy axioms, and these can readily be expressed in first order logic.
