Overview

You must learn various techniques for the fundamental operations of Create, Read, Update, and Delete $($CRUD$)$ to understand and benefit from any database system. You will begin this assignment by creating databases of document collections and performing basic reading or querying operations to retrieve specific documents from the database system. You will also gain practice updating documents and subdocuments, and removing documents from a database. You will use the mongo shell and mongoimport commands to complete this assignment.

Note: This assignment is the only one for Module Two, so it is longer than a typical assignment. Be sure to begin working on it early in the week.

Prompt

After completing the textbook reading and reviewing the mongoimport tool documentation in the module resources, perform the following tasks using the mongo shell in Apporto.

Access the dataset for this assignment, city$\_$inspections.json, in the $/$usr$/$local$/$datasets directory in your Apporto environment. Using the mongoimport tool and documents found in the city$\_$inspections.json file, load the database $$city$$ into the $$inspections$$ collection. Complete this task by typing the following commands in the Linux terminal to perform the import in the right directory:

Change into the Apporto directory with the data sets:

cd $/$usr$/$local$/$datasets$/$

Use the mongo import utility to load the data set:

mongoimport $-$username$=$$$\{$MONGO$\_$USER$\}\backslash$

$-$password$=$$$\{$MONGO$\_$PASS$\}-$port$=$$$\{$MONGO$\_$PORT$\}\backslash$

$--$host$=$$$\{$MONGO$\_$HOST$\}-$db city $-$collection inspections $\backslash$

$--$authenticationDatabase admin $-$drop $./$city$\_$inspections.json

Tip: In any Linux systems, commands must be exact and use proper syntax and case sensitivity$.$

Verify your load by $$using$$ the $$city$$ database, and issuing the following queries in the mongo shell:

db$.$inspections.find$(\{"$id$"$ : $"10021-2015-$ENFO"$\})$

db$.$inspections.find$(\{"$result$"$:"Out of Business"$\},\{"$business$\_$name":$1\}).$limit$(10)$

Provide screenshots of the results as evidence.

Using the appropriate commands in the mongo shell, insert a document to the database named $$city$$ within the collection named $$inspections$.$ Use the following key$-$value pairs as data for your document.

Key Value

id $"20032-2020-$ACME"

certificate$\_$number $9998888$

business$\_$name "ACME Explosives"

date Today's date

result "Business Padlocked"

sector "Explosive Retail Dealer$-999"$

address

number $->1721$

street $->$ Boom Road

city $->$ BRONX

zip $->10463$

Be sure to insert the address as a subdocument and use the JavaScript function Date$()$ for $$Today$$s date.$$ Verify your database creation and insertion using the findOne$()$ function in the mongo shell. Provide a screenshot as evidence.

Answer the following questions using MongoDB queries.

What is the distinct list of inspection $$sector$$ in the current inspections collection? How many are in the list? Do not count by hand.

What is the difference in the date data type for the business named $$AUSTIN $2012$ versus your business document insertion of $$Acme Explosives$?$

How many businesses have a $$Violation Issued$?($See Value column above.$)$

Verify by providing screenshots of the queries and results as evidence.

Using the appropriate command in the mongo shell, update the document with the ID $20032-2020-$ACME$$ in the collection $$inspections$$ in the database $$city$$ with the information below.

Key Value

business$\_$name "New ACME Flowers"

Result "Business Re$-$opened

comments "Flowers after the explosion"

Verify your database update using the appropriate find$()$ function in the mongo shell. Provide a screenshot as evidence.

Using the database $$city$$ with documents found in the $$inspections$$ collection, perform the tasks listed below. Verify by providing screenshots of the results as evidence.

Update all the documents that contain the key$-$value pair "city":"ROSEDALE" in the address subdocument by changing the zip code in the address subdocument to $"76114".$

Remove the first document with the key$-$value pair "result":"Violation Issued."

What to Submit

Submit a Word document containing all your screenshots. Use a screenshot tool, such as the Snipping Tool, and be sure to enlarge the images in the Word document before submission. Doing so will ensure that your screenshots are big enough for your instructor to read them. Refer to this Use Snipping Tool to Capture Screenshots guide for help with taking screenshots.
