The Internet of Things (IoT) refers to a future where everyday physical objects are connected to the internet and can identify themselves to other devices, allowing them to share information with one another and with humans. The concept has been around since 1991, but the term was coined in 1999 by Kevin Ashton. This shift toward IoT has led to significant disruption in how brands, enterprises, and businesses communicate with their stakeholders, resulting in new datasets that demand open, flexible, and connected data models. Graph databases, such as Neo4j, are well-suited to manage this complex information system, allowing for the modeling of entities and relationships between them, which is essential for creating personalized experiences across devices and objects. The use of graphs enables easy querying of data, generating useful information for applications, as demonstrated by a wearable device demo illustrating the connections between wearables, devices, and locations.
