Now run the application to get the answer to hw Here are some URLs that must work when you are done. Write a program in the language of your choice that will remove the lowest homework score for each student. This dataset holds the same type of data as last week’s grade collection, but it’s modeled differently. Please provide the value corresponding to the “answer” key without the surrounding quotes from the document returned.
ObjectId “beaabecff” , “Day”: To figure out what queries you need to optimize, you can read the code in posts. With it, you can test your code and look at the Feedback section. They can also choose to to point mongoProc to any 2. From the top of this page, there was one additional program that should have been downloaded: The blog home page The page that displays blog posts by tag http:
Please provide the value corresponding to the “answer” key without the surrounding quotes from the document returned. To do this, first download the hw But you can, for fun. To figure out what queries you need to optimize, you can read the code in posts.
Note that this is only an example and not the actual document that you would be updating. After you run the blog, you should see the message:.
With the new schema, this problem is a lot harder and that is sort of the point. Reading clockwise from true north, the wind direction is measured by degrees around the compass up to degrees. Use mongorestore to restore the dump into your running mongod.
Now query the profile data, looking for all queries to the homewogk collection in the database school2, sorted in order of decreasing latency.
There are hyperlinks from the post tags to the page that displays the 10 most recent blog entries for that tag.
Your assignment is to figure out the “State” that recorded the lowest “Temperature” when the wind was coming from the west “Wind Direction” between and From the top of this page, there was one additional program that should have been downloaded: One way is to find the lowest homework in code and then update the scores array with the low homework pruned. By fast, we mean that indexes should be in place to satisfy these queries such that we only need to scan the number of documents we are going to return.
Assuming this document has the highest “Temperature” for the “State” of “Vermont” ho,ework our collection, the document should look like this after you run your program:.
Hello from MongoDB!
Remember, just remove a homework score. In this homework assignment you will be adding some indexes to the post collection to make the blog fast. Jongodb will see a message below about your number of submissions, but you must submit this assignment using MongoProc.
Since there is a single document for each student containing an array of scores, you will need to update the scores array and remove the homework.
You should not need to touch any mongoodb code.
This is a comma separated value file that you can import into MongoDB as follows:. In this problem, you will be using an old weather dataset. The blog home page The page that displays blog posts by tag http: When you login or sign-up, the blog will redirect to http: Check all that apply.
Then install the mongodb driver: This homework is meant to give you practice using the “package. Isolate those queries and use explain to explore. There is also a ‘views’ directory which contains the templates for the project and a ‘routes’ directory which contains our express routes.
This assignment requires Mongo 2. When it says “Correct amount of data documents. You can verify that you’ve imported the data correctly by running the following commands in the mongo shell:.
Then you can iterate through the documents and know that whenever the state changes you have reached the highest temperature for that state. To confirm you are on the right homeworj, here are some queries to run after you process the data with the correct answer shown: Now run the application to get the answer to hw
