CALIBRE, a company that works with large government customers, has replaced traditional SQL queries with Neo4j to improve data management and analysis. They have found that Neo4j allows them to easily train analysts and developers alike on the graph database, making it accessible to a wide range of users. By using Neo4j, CALIBRE is able to analyze complex relationships between parts and equipment, such as tracking 10 million parts in a single tank, and build more efficient chairs by identifying interchangeable parts. The company has also seen benefits in terms of speed and ease of use, with Neo4j allowing them to traverse relationships and query the database without writing recursive SQL or dynamic SQL. With Neo4j, CALIBRE is now able to integrate data science and analytics processes, using Python to connect directly to the database and perform tasks such as data retrieval and analysis. Overall, Neo4j has been a game-changer for CALIBRE, enabling them to work more efficiently and effectively with complex data sets.
