Neo4j is a knowledge management system that allows Rob Orlando to create a mastermind and build it into a graph, enabling him to combine near-real-time data with expert knowledge to derive data-driven solutions. He uses Neo4j AuraDB to identify the fastest and cheapest options for his clients, making better decisions faster and accelerating the decision-making process. The Bloom visualization tool is extremely useful in presenting customer presentations, and Rob has found it easier to support multiple clients once he learned how to use graphs. To get started with AuraDB Free, Rob advises users to start with an objective, understand the steps required to meet that objective, and focus on only the datasets needed for that use case.
