Apache Superset Quick Start Guide

By: Shashank Shekhar

Overview of this book

Apache Superset is a modern, open source, enterprise-ready business intelligence (BI) web application. With the help of this book, you will see how Superset integrates with popular databases like Postgres, Google BigQuery, Snowflake, and MySQL. You will learn to create real time data visualizations and dashboards on modern web browsers for your organization using Superset. First, we look at the fundamentals of Superset, and then get it up and running. You'll go through the requisite installation, configuration, and deployment. Then, we will discuss different columnar data types, analytics, and the visualizations available. You'll also see the security tools available to the administrator to keep your data safe. You will learn how to visualize relationships as graphs instead of coordinates on plain orthogonal axes. This will help you when you upload your own entity relationship dataset and analyze the dataset in new, different ways. You will also see how to analyze geographical regions by working with location data. Finally, we cover a set of tutorials on dashboard designs frequently used by analysts, business intelligence professionals, and developers.

Security features

Access to security features in Superset is available only to the admin user. It provides several tools for tracking every user action, login attempt, a list of users, and their permissions.

The user management system is built using the Flask-AppBuilder (fabmanager) framework. The list of permissions and views is inherited from the Flask-AppBuilder framework. Permissions and views are listed in the Views/Menus page of the Security section. A view represents many ways a user can interact with the web application. Each user has a specific set of permissions for actions that it can take when interacting with a web page or view. Viewing or deleting a dashboard are examples of actions.
