The goal of this assignment is to create an app that can capture, tag, save, and retrieve photos on your smartphone.Capture: When clicked, it takes a picture and shows a thumbnail image. Tag: A user can type multiple tags (separated by a “;”). Save: When clicked, it saves the photo in a database along with the tags. Load: A user can specify one or more tags. Your app will find and show the first photo that had any of those tags. When there are multiple photos matching the criteria, the App should have an UI element to show them one by one, e.g., when the user slides a slider.

In Senior Project Website, the user requests the website to search for previous senior projects, the website displays the search web form, the user inputs the keywords to be used for the search process, the user submits the search criteria to the website, and the website requests a remote database to search for senior projects that fulfill the requested criteria (keywords). The remote database returns back a Boolean value (indicating if the search is successful or not) and a list of found senior projects (the list is empty if not successful), If the search is successful, the website displays the list of received senior projects, else, the website displays error dialog box indicating that no projects were found.

Q3: Jami is an intern on a sales team at a large insurance company. On the first day of the internship, Jami is asked to download a list of all of her friends and contacts from Facebook and upload them to the company database. The team lead explains "This database keeps track of all of our employees, and well as their customers and prospects. This makes it really easy to avoid redundant customer interactions, and also keeps us from cannibalizing customers and business from one another." Jami is wondering if there are ethical issues she should be concerned about. Do you think there are ethical issues involved with this situation? If yes- what are those issues, specifically, and how would you advise Jami?
