Find an example of a web form that accepts entries from the user, such as a web-based calculator. If you were<br />
programming this form, what validation checks should be put on each of the input fields? If possible, test the form by<br />
entering some inputs that should be invalid (be careful not to inadvertently place an order for something!). How does<br />
the application respond? Are all inputs properly validated and are the error messages clear? Would you recommend<br />
any changes to this application's data validation?<br />

Validation Controls (graded)<br />
Select one of the ASP.NET validation controls described in this week's assigned reading. Describe how the control<br />
works and provide an example of how you might use it in an application. Under what circumstances would you use this<br />
validation control instead of one of the others?<br />

Web Database Examples (graded)<br />
Find an example of a webpage that displays data retrieved from a database. Which elements of the page are retrieved<br />
from the database and which are hard-coded into the page? What advantage is gained by using a database in this<br />
case? What do you think the SQL query used to retrieve the page data might look like?<br />

HTML, VB, and SQL (graded)<br />
What are the differences among a markup language like HTML, a procedural language like Visual Basic, and a nonprocedural<br />
query language like SQL? What is the role of each language in programming a web application? Why is it<br />
important for a web developer to know all these languages?<br />

CRUD Operations (graded)<br />
Find an example of a website that allows users to perform each of the CRUD operations on a database: creating data,<br />
reading data, updating data, and deleting data. You may be able to find one site that allows you to do all of these, or<br />
you may need to look at multiple sites. How does the user perform each operation through the web interface? Can you<br />
suggest alternative ways of implementing these operations?<br />

Differences in Desktop and Mobile Sites (graded)<br />
Visit one of your favorite websites in your desktop browser, and then visit the same site using the browser on a mobile<br />
device (tablet or phone). What, if any, differences do you see? Why do you think those differences exist? Are some<br />
activities easier on the desktop site than on the mobile site, or vice versa? Would you suggest any changes to the<br />
desktop or mobile sites based on your comparison?<br />
