On the first screen of the app, users are provided with five parameters: house prices, grades from nearby schools, crime rate, green space, and transport links. Once their preference information is submitted, the app sends a query that creates an HTTP get request. This query sends a chain of events to Bluemix that pulls in relevant data sets from the database that are formatted within Node-RED and sent to the Watson Trade-Off Analytics API. At the back end, Trade-Off Analytics compares user data with the borough options and cross-checks it with the unstructured external sources that are fed through and analysed by the Watson Alchemy API. The response is sent back and pushed down to the app to display the outcome screen of the HTTP get request. All of this is under-pinned in a workflow set up in Node-RED.
