Data Engineering Nanodegree (DEND)

This repository contains my notes and projects from Udacity's DEND.

It uses Anaconda and Jupyter Notebooks and was run on WSL.

Environment

The Environment has been packaged in dend.yml.

To recreate:

$ conda env create -f <environment-name>.yml

To update dependencies:

$ conda env update -f <environment-name>.yml --prune

Global Dependencies

The following might be needed depending on the Notebook or Script that you are executing.

PostgreSQL

Steps might differ on your system but the gist is to create the following:

1. Database named studentdb
2. User named student with password student

$ sudo apt update
$ sudo apt install postgresql postgresql-contrib
$ sudo adduser student
$ sudo service postgresql start
$ sudo -u postgres psql -c "SELECT version();"

And then change the password for student in the db.

Cassandra

I had to do some tricks to get Cassandra running on WSL but it is entirely possible, it might take a while to start.
