Neo4j is a graph database that has been gaining popularity in the industry, and its user, Dee Pandian, a Deputy Director of CyForce at Jacobs Engineering, has had a transformative experience working with it after 18 years as a SQL developer. She initially found Neo4j's concept different from her usual work with SQL Server but soon discovered its power through a project involving a large data set. The results showed unexpected relationships between systems, which led to a "wow moment" and a shift in her approach towards graph technology. Since then, she has started using Neo4j for various projects and appreciates its speed, accessibility, and ease of creating relationships. Her experience with Neo4j has been so positive that she now leans towards graph technology and is looking forward to utilizing the platform's new ETL tool instead of her own custom one.
