This repository contains the implementation I did while reading the book. All SQL queries as well as a description how to setup everything on Windows 10 using Docker are also part of this repository.

Quickstart

1. build the Docker images docker compose build
   • or docker-compose build db to build the database image alone
2. docker-compose up -d to download the Docker images and start the containers
3. download the RAW cassini data from Redfour
4. store the files under ./curious/data
5. docker exec -it curious_db bash to open a Bash on the Postgres container
6. cd /home/curious to browse the mounted directory with the make file and raw CSV data
7. make import_master_plan to import the master plan data into the enceladus database
8. localhost:5050 to open a pgAdmin window on the Docker host machine (your local machine)
9. login with [e-mail] and 123456 to login to the pgAdmin
10. create a server connection to the Postgres server using curious_db:5432 and [e-mail] with mysecretpassword to browse the enceladus database

Get the Cassini RAW data

Download the raw data from http://archive.redfour.io/cassini/cassini_data.zip. To begin with I am only interested in the master_plan.csv file. The other files cda.csv, inms.csv, jpl_flybys.csv, and chem_data.csv will also be necessary later.

Use PGAdmin to connect to the database

The docker-compose.yaml file contains a pgAdmin container additionally.

Open the browser on your host machine (your local machine) and visit http://localhost:5050. Use the email [e-mail] with the password 123456 to login to pgAdmin

Make a new server connection curious_db with port 5432 and username postgres and password mysecretpassword.

Name the connection Curious-Moon-Enceladus.

Create a Database using PSQL

Open a Bash on the Docker container.

psql -U postgres to open the Postgres shell (PSQL) for the user postgres to type SQL commands directly.

E.g. create database enceladus; to create a database if it is not there yet (e.g. if it was dropped before)

Type \q to exit Postgres shell (PSQL).

Images

I really liked Dee's drawings to make things clearer - that's why I drew them myself.
