Fоr this questiоn; yоu will choose to complete ONE of the two questions found below. QUESTION 1 - Normаl Level Question - Mаximum mаrk 16/20 You have been tasked with identifying which of two systems a company should choose for an upcoming project. The project is a community chat system extension that will add new functionality to an existing chat system that currently supports approximately 75 million users. This new file attachment feature will allow users to include an attached file with their messages. Your proposed system must keep this functionality by storing a userID, a date, the file type (one of three file types - image, video, file), and the file itself. The system's front end will limit the size of attachments to 50 Megabytes per attachment. The system has approximately 10 million daily users, and it's expected that about 50% of them will begin to use this new file attachment feature. Your manager has asked for a report in the form of a jyputer notebook, which proposes using either Cassandra or MongDB. The notebook must also provide a set of example python functions that will illustrate the programming interface to the system. The example functions should include a function to add a file attachment, to search for and return a file attachment, and to delete a file attachment. You should also have a code section that tests each function. Your report should be of professional quality (demonstrating good use of markdown). It should present a rationale for choosing your chosen system (present the reasons for selecting one system over another). NOTE: You will need a file to demonstrate this functionality. You can write a Python script to generate this file by creating a file and adding random text to this file (you can repeat a phrase many times). You want this file size to be at least 1 megabyte. NOTE: The Cassandra system is a 5-node cluster. The MongoDB system consists of a single replica set with a primary and three secondary nodes. The evaluation of your submission will include the following: 1) Overall professional quality and readability of the notebook 2) A discussion about the rationale for the selection of the system chosen that demonstrates your understanding of these two systems. 3) The code - organized, includes comments, and does what is expected (remember, these are functions that you are creating and testing - so you will have a function like store_file, retreive_file, delete_file) ** Your submission should include your generated file and the notebook you created. (if you used a separate notebook to generate the file, also include it) ** NOTE: If you struggle with this question, be sure to do the best you can to submit a full notebook -- if there was something you didn't know how to do, put in a Python comment stating this, and continue with the rest of the code assuming that you were successful in implementing the previous code... your code will not run if you do this, but at least you can demonstrate your understanding of some of what is required. Recall that the basic syntax for file creation is as follows: with open("filename.txt:", "w") as fout: fout.write("some text") Recall that the basic syntax for reading a file is: with open("filename.txt:", "r") as fin: tmp = fin.read() # this will the entire file and store in the variable tmp Recall that the basic syntax for creating a function is: def some_function(some_list_of_parameters): return QUESTION 2 - Easy Level Question - Maximum mark 16/20 Your manager has asked you to assist in creating an extension to an existing song database system. The current system stores information on the song and users who are registered with the system. You have been asked to create a table in Cassandra to store the song information. This information will include a unique SongID, Title, Duration (in seconds), and Genre (either pop, rock, classical, or country). You must also demonstrate the functionality by creating this table, adding a record to this table, updating an existing record in this table, and deleting an existing record. All your code will be created in one notebook. You must submit the notebook file to both Canvas and as a pull request to the class repo. The filename must be your full name, with each word separated by an underscore (for instance, mine would be timothy_smith.ipynb). The location that you will insert into the repo is the folder MidTermSection01. Both the canvas submission and the pull request must be received before the submission deadline. NOTE: The Cassandra system consists of 5 nodes. The evaluation of your submission will include the following: 1) Overall professional quality and readability of the notebook 2) A discussion about the rationale for your selection of keys and keyspace. 3) The code - organized, includes comments, and does what is expected 4) Successful pull request
