Before you get started, I assume that you are running Ubuntu 16.04LTS Desktop or above and have done your Python 101 course. Knowledge of how to install the relevant software packages is assumed and will not be covered in this book.
Three database engines (SQLite, MongoDB, and Neo4j) are used in this book. Please make sure that you have them installed.
Regarding data sources, we will get data from data.world (https://data.world/) and a paid subscription to Quandl (Sharadar Core US Equities Bundle (https://www.quandl.com/databases/SFA/data) for chapters 4 and 5, and Sharadar Fund Prices (https://www.quandl.com/databases/SFP/data) for chapters 6 and 7), Twitter's Premium Search (https://developer.twitter.com/en/docs/tweets/search/overview/premium) for chapter 7, and the Open Bank Project (https://uk.openbankproject.com/) for chapter 8.
