POS/409 Week 2


Learning Team: Designing and Planning the Learning
Team Project
Includes Working Application Instructor Feedback - Perfect Score
Software developers are often hired as contractors to work in teams to accomplish
software development tasks. Over the coming weeks, you will build a Universal
Windows Platform (UWP) application as a team of contractors. Each week your
team will build a portion of the program.
As a team, examine the following programs and the linked sources data,
and select one to complete by the end of the course:
Create a program that will allow the user to enter a zip code and show the
weather for the zip code entered. (Possible source of
data: https://www.wunderground.com/weather/api/d/docs)
Create a program to search the World Wide Web. Keep track of the last 10
searches the user entered. (Possible source of
data: https://developers.google.com/custom-search/json-api/v1/using_rest)
Create a program to take in two locations and show the driving directions
between those two points. (Possible source of
data: https://developers.google.com/maps/documentation/directions/start)
Note: Each of the programs can be accomplished by creating a UWP application
calling an Application Programming Interface (API) using a Representational State
Transfer (REST) web service.
For your team assignment this week, create a 1- to 2-page document using
Microsoft® Word including each of the following:
Identify and investigate the service you will use and the data the service will
return.
Investigate whatever setup you need to do in order to use the selected API,
including registering for a developer key.
Use a tool like Postman to test the API and make sure it will work for you (use
the link to download Postman).
Complete the initial class design for your selected program including
properties and collections.
Complete the initial user interface design for your program.
Create a project plan for the work you will do with clear expectations for each
team member.
Note: The Learning Team Assignment Tips document will help you as you work
through all the steps to build your Universal Windows Platform application.
Submit your assignment.

Individual: List Collections
Perfect Score
Upon further review of the previous assignment, you have determined that you can
make your application (from Week 1) more efficient by replacing the arrays with
Lists.
Your application will need to implement the first 3 requirements AND the 5th of the
Week 1 assignment.
For requirement #4, you will do the following: Load employee information from a
text file selected by the user into a LIST Collection consisting of Managers and
Developers. The format of your text file should be something like this:
First Name, Last Name, Street Address, City, State, Zip, Employee Type (Manager or
Developer), Cost Center (0 if Developer), Supervisor, Tax Type (NA if Manager)
There should be a separate line for each employee (only one line per
employee with the fields above) and your file should contain at least 7 – 10
employee records. You should save the file with a .txt or .csv extension.
The following requirements detail the critical elements that will determine the
grading criteria for your submission. Please see the rubric below these requirements.
The application should compile and run successfully
The application should display Inheritance(Steps 1 – 3 from Week 1).
The application should allow the user to load a text or csv file for processing
(Step 4 above).
The application should load the text file elements into an array of employee
records (Step 4 & 4a above).
The application should display records from the array. The number of records
to display should be selected by the user. (Step 5 fromWeek 1).
Your application should contain comments to explain the data and process
flow of your code.
folder.
Submit your ZIP file.

Discussion Question: Collections in REST API Calls and
C# .NET Collections
Many applications get their data from the internet. This is done in various ways, but
one of the most common ways is to use REST (Representational State Transfer) and
make calls to get data over HTTP (Hyper-Text Transfer Protocol). REST API's center
around resources grouped as a collection.
There are many open APIs (Application Program Interfaces) that are free and can
be used to get data from different sources. Click the link to view an example of the
code to make a currency conversion that you can access in your browser.
As you can see data is often returned as a collection of objects.
Discuss how REST is commonly used in calling an API to get data and discuss the
different data formats that are used in this type of data transfer.
Knowing when to apply collections on a given business problem is an important skill
for developers to know.
Using the information from Lesson 7, "Managing Collections of Data," of the
Lynda.com® course C# Essential Training, select one .NET collection,
and explain possible benefits of implementing the selected C# collection.
From the perspective of the IT manager, discuss business problems that could be

solved using the selected C# collection.

POS/409 Week 3


Learning Team: Class Design, Construction, and Testing
Perfect Score
You and your team of software development contractors are moving forward with
the steps to build your Universal Windows Platform (UWP) application.
Using the document you created for last week's Learning Team
assignment, read the information on the attached "Basic Queries (LINQ to XML)
(C#)" tutorial, and research where you will get the data for your program design.
Use this information to build the classes you will use for your selected team program.
Remember, the query class represents the base class for executing search queries.
Create a simple application that demonstrates and uses the classes. You could
mock-up the data that the service API will provide by using LINQ. Each team
member should be contributing to the construction of the code and reviewing the
code and design. Each team member needs to know how to build, debug, and run
the program.
Note: Each week's Learning Team assignment will help you complete your Week
Five Individual Assignment.
