WebIn the programming world, trees and graphs are important factors and depict nonlinear data. A tree is an exceptional case of a graph which does not loop whereas graphs can have loops. Both graph and tree share some common features but they do have some differences. Let’s explore the differences between tree and graph. What is a Tree?

WebAs graph databases can jump from one entity to a related one just by following a memory pointer, we call this index-free adjacency. We do not have to find a foreign key in a different table (using an index) or — even worse — find a key in a mapping table, and the resulting foreign key in a third table to follow a relationship.
