The text discusses the application of graph databases in analyzing data from a science fiction show, Doctor Who. The database contains information on characters, locations, and connections between them, making it suitable for graph-based analysis. By examining the relationships between characters and enemies, the authors found interesting insights such as the Master being the biggest thorn in the Doctor's side with 33 appearances and nine incarnations. Graph databases also have a significant impact on businesses by enabling new kinds of applications and providing unique insights from established data-sets, particularly in areas like route optimization and customer relationships. Companies like Shutl are using graph databases to improve their operations, such as determining the quickest possible delivery routes, which can save time and provide better customer experiences. Graph databases offer a scalable alternative to conventional relational databases, allowing for faster performance and more efficient analysis of complex data-sets.
