In 2008, I joined MarkLogic and became a big advocate for NoSQL technologies. Many problems are better addressed with NoSQL technologies like XML, key-value pair, document, and graph databases. When I joined FactGem as Chief Technology Officer in 2013, we needed a database that didn't require a fixed schema to store user-uploaded data from Excel files without technical expertise. We initially built on MarkLogic, but later realized the importance of data relationships between entities, leading us to transition to RDF-based databases like Neo4j, which met our high performance and flexibility needs, allowing us to focus on relationships between entities in the database.
