Data analytics is a trendy field with many solutions available. One of them is Cube.js, an open source analytical platform. You can think of Cube.js as a layer between your data sources and applications. As the diagram below shows, Cube.js supports serverless data warehouses and most modern relational database management systems (RDBMS). You can work with any JavaScript front-end library for data visualization, and Cube.js will take care of the rest, including access control, performance, concurrency, and more. read more
