Project Scenario

As a data engineer at a Data Analytics Consulting Company, we take pride in our ability to efficiently handle data in any format on any database platform. The analysts in our offices rely on me to move data from external sources into various databases, transfer data between different types of databases, and execute basic queries across various databases. It’s a critical role that ensures our analysts can focus on analyzing data without worrying about the technical intricacies of data movement and management.

Objectives

Replicate a Cloudant database
Create indexes on a Cloudant database
Query data in a Cloudant database
Import data into a MongoDB database
Query data in a MongoDB database
Export data from MongoDB
Import data into a Cassandra database
Query data in a Cassandra database

Directions

Task 1 - Replicate a local database into your Cloudant instance.
Task 2 - Create an index for the Director key, on the movies database using the HTTP API.
Task 3 - Write a query to find all movies directed by Richard Gage using the HTTP API.
Task 4 - Create an index for the title key, on the movies database using the HTTP API.
Task 5 - Write a query to list only the year and Director keys for the Top Dog movie using the HTTP API.
Task 6 - Export the data from the movies database into a file named movies.json.
Task 7 - Import movies.json into mongodb server into a database named entertainment and a collection named movies.
Task 8 - Write a mongodb query to find the year in which most number of movies were released.
Task 9 - Write a mongodb query to find the count of movies released after the year 1999.
Task 10 - Write a query to find out the average votes for movies released in 2007.
Task 11 - Export the fields _id, title, year, rating and director from movies collection into a file named partial_data.csv.
Task 12 - Import partial_data.csv into cassandra server into a keyspace named entertainment and table named movies.
Task 13 - Write a cql query to count the number of rows in the movies table.
Task 14 - Create an index for the rating column in the movies table using cql.
Task 15 - Write a cql query to count the number of movies that are rated 'G'.

Setup

Before proceeding, complete the steps in the How to Create an IBM Cloudant Instance document to create a free multi-tenent Cloudant instance.

Note: This repo can also be used for local NoSQL database migration and analysis. You must have MongoDB Server and Apache Cassandra already installed. Refer to the links below:

Start the MongoDB and Cassandra processes according to your environment.
