PART 1 – QUERYING AND UPDATING THE DOCUMENT DATABASE (50 POINTS)
MongoDB is an open-source document-oriented database that is designed to store large scale data.
It is categorised as a NoSQL (Not only SQL) database because the storage and retrieval of data in the
MongoDB is not in the form of tables and querying does not have to be done using SQL. Additional
learning materials for MongoDB can be found on COMP643 LEARN Page.
In Assignment 2, Part 2, you used a database to process orders for roses. A subset of this database
have been converted to MongoDB. You can download the JSON file (“rosesdb.json”) for creating this
database in your local machine.

the queries in a text file, each query MUST be labelled with the question number (e.g, 1a).
