 ## What can users do with the data once downloaded to DB ?
-That is entirely up to them ;-). This service uses Pg_Web as data exploration and manipulation tool and Apache Superset for data visualizations. As mentioned previously each user has his own database that is not shared with other users and has a full access to it from anywhere on the Internet by default (might vary if used privately). The database, once created and populated with data, combining records from different sources would predominantly be used as a datasource for data analysis, data visualizations, machine learning or for data archiving purposes. The user can use the included Pg_Web or Apache Superset or any free or paid third party tools like PowerBI, Tableau, Dash, Plotly etc.to explore, manipulate or visualize the data. The DB can also be used as a datasource for ML models or just as a data archive.
