The author of the tutorial aims to build a metrics dashboard for an e-commerce company's sales team using Cube Cloud and Retool, two low-code solutions. The author sets up a Cube Cloud deployment on AWS, connects it to a PostgreSQL database, generates a data schema, and runs queries to determine what data is needed for the charts and graphs. The author then integrates Cube with Retool, creates a new app and resource in Retool, and uses drag-and-drop components to build the dashboard, binding the data from the Retool Query to the actual charts. The final dashboard displays e-commerce KPIs, including orders created per day grouped by status, and includes dynamic elements such as a date picker. The author concludes that Cube Cloud and Retool are a great match for building business applications with minimal effort, enabling users to create breathtaking metrics dashboards and internal tools with almost no code.
