Notes on validation The Python validation script requires the following python modules be installed on your computer: ObjectId “52c52aeaead11dc55” , “hello”: Do this by opening a terminal window mac or cmd window windows and navigating to the directory so that the dump directory is directly beneath you. It is not an orphan. ObjectId “52c52ae8ead11dc54” , “hello”:
Model Data to Support Keyword Search. ObjectId “52c52ae2ead11dc53” , “hello”: That is, think mostly about the operational aspects of such a system. ObjectId “52c54de5ead11dc5a” , “fname”: Do this by opening a terminal window mac or cmd window windows and navigating to the directory so that the dump directory is directly beneath you. This operation will return all documents in the inventory collection where the value of the type field is ‘food’. If everything works, you should see your username when you are redirected to the welcome page.
ObjectId “52c52addead11dc50″”type”: ObjectId “52c52addead11dc51″”egg”: Return Specified Fields Only: Please use the Enron dataset you imported for the previous problem.
There is a dump of the video database included in the handouts himework the “Creating Documents” lesson. ObjectId “52c54c93ead11dc57″”fname”: Iterate a Cursor in the mongo Shell: Create a Sparse Index.
Imagine an electronic medical record database designed to hold the medical records of every individual in the United States.
We will take that to mean they don’t really live in a city. You can also use the cursor method next to access the documents, as in the following example: You will need to fix that in a stage of the aggregation before doing your grouping and counting of sender, recipient pairs. Indexes provide high performance read operations for frequently used queries.

Now issue the following command to reload your repository: ObjectId “52c54de5ead11dc5a””fname”: Model Data for Atomic Operations. MongoDB for Developers Homework 2.
ObjectId “52cdde87″”fname”: Now suppose you want to run the hommework query against the collection. The query did not utilize an index to figure out which documents match the find criteria.
In this problem you will calculate the number of people who live in a zip code in the US where the city starts with a digit.
[Solution] Week 2 : CRUD: MP: MongoDB for Developers
To do this, you will need to unwind the To list for each message. ObjectId “52c54d73ead11dc58″”fname”: You should see three files at the highest level: Build a replica set and insert data into the secondary nodes to free up the primary nodes. Every image is supposed to be in an album, but there are orphan images that appear in no album.
That is, think mostly about the operational aspects of such a system.
Enron was an American corporation that engaged in a widespread accounting fraud and subsequently failed. Has no effect on update operations that modify existing documents. Create an Auto-Incrementing Sequence Field: Did you notice the links in the previous sentence?
Please query the video. Model Tree Structures with Nested Sets. ObjectId “52c52ae8ead11dc54″”hello”: Inspect a few of the documents to get a basic bomework of the structure.
