You can verify that you’ve imported the data correctly by running the following commands in the mongo shell:. You should not need to touch any other code. In this homework assignment you will be adding some indexes to the post collection to make the blog fast. If everything is working properly, you should be able to start the blog by typing: If you select all the weather documents, you can sort first by state, then by temperature.
Then you can iterate through the documents and know that whenever the state changes you have reached the highest temperature for that state. Please query the video. The blog has been enhanced so that it can also display the top 10 most recent posts by tag. You might want to start by inspecting it in the Mongo shell. Use that data set to answer this question. Use the weather dataset that you imported in HW 2.
There is also a ‘views’ directory which contains the templates for the project and a ‘routes’ directory which contains our express routes.
But you can, for fun. The templates comprise the view. You must load this dataset to complete the problem. Now it’s your turn to analyze the data homrwork.
That will return one document.

In this problem, you will be using an old weather dataset. 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 If you select all the weather documents, you can sort first by state, then by temperature.
This is a sample document from the weather data collection: Don’t remove a quiz or an exam!
You should not need to touch any other code. To start, please download sysprofile. 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. To confirm you are on the right track, here are some queries to run after you process the data with the correct answer shown: Assuming this document has the highest “Temperature” for the “State” of “Vermont” in our collection, the document should look like this after you run your program:.
Hello from MongoDB!
Note you will need to have your path setup correctly to find mongorestore. Sunday, January 22, [Solution] Week 2: Then you can iterate through the documents and know that whenever the state changes you have reached the highest temperature for that state. To figure out what queries you need to optimize, you can read the code in posts.
Once you have added the indexes to make those pages fast, just validate your work with MongoProc. In this problem, you will be using a collection of student scores that mongdob similar to what we used in the lessons. You might want to start by inspecting it in the Mongo shell.
The database calls that you are mongkdb to add will add a new user upon sign-up and validate a login by retrieving the right user document. To do this, first download the hw Use the weather dataset that you imported in HW 2.
There is a dump of the video database included in the handouts for the “Creating Documents” lesson. After you run the blog, you should see the message: Workspace infoupdated a year ago mongodb-courses-mjs.
