shows how a display of most-significant product categories in

cataloged in the dominant categories of that nature, suggesting a missed
sales opportunity.
Using node-link representations of products and customer interests, this
example has shown how graph databases and queries are used to extract
valuable, focused business insights from Big Data. The next section
examines methods for analyzing all of the data and the situations in which
that has value.
