MongoDB and AXA France: Creating a Connected Homes Project` is an initiative by the insurance company AXA France to leverage the Internet of Things (IoT) technology in their home security solutions. The project utilizes MongoDB as its database management system, allowing for efficient storage and processing of large amounts of IoT sensor data from multiple devices within a single connected home. By aggregating this data, AXA France can provide customers with real-time control and monitoring capabilities to protect their families and property. The use of MongoDB's aggregation pipeline enables the analysis and reporting of sensor data, while also simplifying application code with features such as document validation and the $lookup operator. The development team found MongoDB to be an ideal choice due to its ease of installation, configuration, and agile development capabilities, which allowed them to develop new features quickly and efficiently.
