CS 340 Milestone One Guidelines And Rubric 

Overview:For This Assignment, You Will Implement The Fundamental Operations Of Create, Read, Update, And Delete (CRUD) In Either Python Or Java. You Will Use The Language-Specific MongoDB Driver To Create CRUD Functional Access To Your Document Collection. 

At This Point In The Course, You Will Need To Select The Programming Language You Would Like To Use. (You May Choose Whichever Language You Prefer, But Considering The Opportunities In Your Program, We Do Recommend Python.) Keep In Mind That You Must Use Your Chosen Programming Language For The Remainder Of The Course (Milestone Two And The Final Project) Because Your Assignments Will Build On Each Other Starting With This Milestone. 

Reminders 

  • To Create A Code File In Codio, Right-Click On The Briefcase Icon Next To Your Codio Project And SelectNew File. Refer ToThis VideoFor Further Guidance. 
  • To Download A Code File In Codio, Right-Click On The Document Icon Next To Your Codio Text File And SelectDownload. 
  • Type All Python Code Into Your Codio Terminal Manually, Especially When Running The Python Example Code Below. Python Is Space-Sensitive And Does Not Copy Into The Codio Terminal Well. 

Prior To Completing The Prompt For This Assignment, Run The Following Code In Your Chosen Language. 

Example Python Code To Insert A Document 

Import Json From Bson Import Json_util From Pymongo Import MongoClient 

Connection = MongoClient(‘Localhost’, 27017) Db = Connection[‘MyDB’] Collection = Db[‘MyCollection’] 

Def Insert_document(Document): 

Try: Result=Collection.Save(Document) Except ValidationError As Ve: Abort(400, Str(Ve)) Return Result 

Def Main(): 

MyDocument = { “KeyName” : “Test Value Data”} 

Print Insert_document(MyDocument) 

Main()

Prompt:After Completing The Textbook Reading For This Module And Reviewing The Other Resources, Use The Codio Editor And Your Choice Of Python Or Java To Complete The Following Tasks In Codio. For Each Task, Provide A Text File (Either A.JavaOr.PyFile) Of Your Code And Screenshots Of Execution As Evidence.
