Link Coefficient

Given a database, how interconnected is the database?

Key Idea

Given $n$ nodes, there can be $n(n-1) \over 2$ total possible links if every single node is connected to the other. How many links exist compared to that fully-linked database?

$$\text{Link Coefficient} = {\text{Existing Number of Links} \over \text{Total Possible Number of Links}}$$

For example, as of 230216, Aldehyde has a 0.592% of Link Coefficient.
