The best part about superset is that it not only allows you to use existing data sets, but also has its own internal databases which can be used for creating new datasets! It's very easy to work with and comes with an interactive user interface. I like how fast it loads compared to SQLite or PostgresSQL database systems. It doesn't have any downsides; everything works as expected. You must try this tool if you are working in Data Science field. We're using superset to help process big volumes of financial information, and it does so extremely well.
