These tutorials are an introduction to FIWARE QuantumLeap - a generic enabler which is used to persist context data into a CrateDB database. The tutorial activates the IoT sensors connected in the previous tutorials and persists measurements from those sensors into the database. To retrieve time-based aggregations of such data, users can either use QuantumLeap query API or connect directly to the CrateDB HTTP endpoint. Results are visualised on a graph or via the Grafana time series analytics tool.

The tutorials use cUrl commands throughout, but are also available as Postman documentation
