SQL-for-Data-Analysis

This repository contains the quizzes along with their SQL commands for the concepts taught in the course SQL for Data Analysis by MODE at Udacity.

You can restore the toy dataset "parch and posey" to your local machines from the file parch_and_posey_db using the following steps:

1. Open Terminal.
2. Enter PostgreSQL console - psql
3. Create a new database - CREATE DATABASE parch_and_posey;
4. Restore into the database - pg_restore -d parch_and_posey /path/to/parch_and_posey_db

NOTE: The data dump file and the above commands works well with PostgreSQL (may or may not work with MySQL and others).

Now, SQL commands can be used to explore the dataset and run queries on it.

Here is the schema of the database used for all the queries.

I have also included the screenshots from the videos for some important and useful concepts that may need revision in future.

For the remaining ones, please refer these SQL Tutorials (by MODE as well).
