The text discusses the integration of graph databases with the Internet of Things (IoT) to create smart services that can handle large amounts of data and produce actionable outcomes. The author highlights the limitations of traditional relational databases in handling IoT data, which requires complex event processing and un-foreseen matches to deliver business value. Examples are provided, such as Uber's use of graph databases to optimize taxi service, and a building management system that uses graph databases to predict maintenance needs. The text also touches on the challenges of storing and processing large volumes of IoT data, including the need for flexible data stores like graph databases. As the enterprise focus shifts towards investing in new digital business offerings, the author predicts that IoT-supported smart services will become the norm, leading to increased use of graph data.
