Graph databases are becoming essential tools in discovering, capturing, and making sense of intricate relationships and interdependencies within the Internet of Things (IoT). The value of devices in the IoT lies not only in their individual capabilities but also in the connections between them. Graph databases store and process data by bringing these connections to the fore, providing significant performance and ease-of-use advantages, as well as unparalleled ease in evolving the data model. This enables businesses to identify opportunities for new services and products that make the most of the IoT, such as optimizing supply chains, analyzing network behavior, and detecting failures. By reducing the wash of data to its common denominators – the connections between devices – graph databases provide a natural way to represent these connections, allowing companies to navigate the complexities of the IoT and unlock new business value.
