This exаm is wоrth 100 pоints. It cоnsists of writing severаl MongoDB queries аnd MongoDB tools commands. The submitted JS file must run in order to be graded. If one of your queries does not work you should comment out the query so the rest of your queries run. No credit will be given if the .js file does not run with mongosh. This is an individual assignment. You MAY NOT consult with other students. The only allowed references are: MongoDB documentation: https://www.mongodb.com/docs/ The regex “cheat sheet” on myCourses Crib sheet: 8½" x 11" (A4), hand-written, double-sided You may not access any files that you or anyone else have written for this course. Download the practical starter files from here: mongo_practical_start_610.zip Rename the JS starter file to practical_YourName.js before beginning. When you're done, be sure to zip your file before uploading the file below. Load the provided exam_tweets.json into a collection named “Tweets” in a database named “ExamSocial” using mongoimport. Paste the command into the comment in the JS file. Insert a document with the following information into the Tweets collection. fromUser: your RIT username; for example: abc1234 fromUserName: your name here text: “Semester of Mongo 2025!”Show the results of the insert (i.e., the JSON object with “acknowledged: true”). Write a query that selects the document you entered above using the fromUser field. Project only the fromUser, fromUserName, and text fields. Write a query that updates the text field in the above document to say:"And now on to Neo4j!".Do not update the other fields in the document. Show the results of the update (i.e., the JSON object with “acknowledged: true”). Repeat query #3 here to see if the update worked (copy/paste #3). Write a query that will delete the document you added in #2 above using the fromUser field for selection. Show the results from the deletion (i.e., the JSON object with “acknowledged: true”). Using regular expressions similar to what we have done in class, select all the documents that contain both of the two following words in the text field: “great” – the full word; no stem words – it should not find “greatness” “not” – the full word; no stem words – it should not find “knot”The words can be in either order in the document.Both words should be complete words with no prefix of suffix (additional letters).The search should be case insensitive.Show only the _id and text fields in your results. This question is about using GridFS: Using mongofiles on the OS command line, take the sandy.png file and insert it into the ExamSocial database. Paste the command you used into the corresponding comment in the JS file. Write a query that selects everything from the fs.files document that was created when you ran mongofiles. For all documents in the collection, add a new property called tweetLoc whose value is a GeoJSON point built from latitude and longitude. Do not delete the latitude and longitude properties. Show the results from the update. Add an index to the new tweetLoc property to support GeoSpatial queries. Show the results from adding the index. Write a geospatial query to find the tweet that’s within 50km of: latitude: 36 longitude: -115Project only the text, latitude, and longitude fields. Once you are done with the exam, zip up your JS file and attach it here with the "Add a file" button below. You don't need to type anything into the text area response field.
