Background

World of Words (WoW) is a site which lists top charts of iTunes word games. They have asked you to come up with a database using MongoDB to be able to store the top word game apps to allow viewers to easily search for top word games.

Some game details

  • Every game has a unique identifier
  • Every game has at least 1 genre identified, but can have up to 4
  • Some games support all platforms, while others don’t
  • Every game has at least 1 language identified, but can have up to 8
  • Developer details include ID, Name and URL
  • Latest version details are stored, which include Version No, Release date, Notes, and user ratings.
  • Games also have an overall rating (which includes the latest version ratings)
  • Ratings are out of 5. Comments are not stored.

Part A - Database

  • Create a MongoDB database using the data provided to you in the GameData_Task3.xls spreadsheet. (There should only be one collection).
