Understanding the Problem Statement

Let’s understand the problem we’ll be solving in future. This will give you a good idea of the kind of projects you can pick up to further hone your MongoDB in Python skills.

Suppose you are working for a banking system that provides an application to the customers. This app sends data to your MongoDB database. This data is stored in three collections:

• The accounts collection contains information about all the accounts
• The customers collection contains information about a customer
• Finally, the transactions collection contains the customer transactions data

I have taken the sample database from MongoDB Atlas, a global cloud database service. We will use the ‘sample_analytics’ database to work on this problem statement. This database contains data related to financial services.
