Code from 'Big Data' course in the university

We set ourselves the goal of developing a web hosted application that will provide the user with the following functionality:

• Store information about the history of price changes for games.
• Predict the price change for games.
• Receive notifications about price changes for the game.
• Leave comments and reviews for the game.
• Recognize comments and evaluate the game based on them.

In order to fully understand the goal that we set for ourselves and the problem that we want to solve, following questions were formed:

• Try to schedule the purchase of the game to buy it at a good discount.
• Try to find all the information you need about the game in one place.
• Based on comments from other users, try to form an overall rating for the game.

As a result of completing the task, we expect to have a web hosted application that is able to:

• Provide information for user about games and provide history of price changes for the games.
• Provide information for user about possible price changes and discounts for the games.
• Send notifications to user about price changes for the followed games.
• Store users review and recognize them to evaluate the game.
