Individual: Record Objects

Includes Working Application and Instructor Feedback - Perfect Score

You are a software development employee at a startup company. Your HR department has tasked the IT department with developing a simple application (Windows Form Application) to load and display employee records. 

Your application will need to do the following:

Create an Employee Class with the following properties:

• First Name
• Last Name
• Street Address
• City
• State
• Zip

Create a sub class for Managers which inherits from the Employee Class. The Manager class will have the following additional properties:

• Cost Center
• Supervisor

Create a sub class for Developers which inherits from the Employee Class. The Developer class will have the following additional properties:

• Developer Type(Script, .NET, Mobile, etc.)
• Supervisor
• Tax Type (W2, 1099-Contract)

Load employee information from a text file selected by the user into an array 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)

1. 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 UI should allow the user to select how many records to view (start at 3 and allow up to the total number of records loaded).

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 above).
• 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 5above).
• Your application should contain comments to explain the data and process flow of your code.

Zip your Visual Studio® solution project folder so it can be submitted for grading. In Visual Studio®, you can locate the folder with your solution by left clicking on the solution node in the Solution Explorer. Look at the Properties window to find the folder name in the Path property. Locate this folder in File Explorer and zip the folder. 

Submit your ZIP file using the Assignment Files tab.

• 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)

• 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.

Discussion Question: Collections in REST API Calls and C# .NET Collections

Includes 3 individual replies to this discussion question!

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.

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.

Zip your Visual Studio® solution project folder so it can be submitted for grading. In Visual Studio®, you can locate the folder with your solution by left clicking on the solution node in the Solution Explorer.
