Respond to the following in a minimum of 175 words:
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.
Replacement video if above is not available: This is a good video: Learning C# with Alex Zanfir. Section 1 touches on Collections at the very end. I recommend watching all of Section 1 to understand the code example used in the Collections part of the video.

From the perspective of the IT manager, discuss business problems that could be solved using the selected C# collection.

Discuss different approaches you might use in a .Net program to simulate data, including using LINQ and XML.
Considering the information you learned in Ch. 22, “Operator Overloading,” of Microsoft Visual C# Step by Step about the .NET operator overload, determine possible benefits of implementing or modifying code by using operator overload on a business application.
You are hired on an application development team for a business. Discuss possible business challenges that could be enhanced by using operator overload.
