Behind the scenes Hi everybody, My name is Abhinav Chhabra and I am going to take you through our application screen by screen and let you know, what actually happens behind the application.

Before launch Now, this is how the icon for our application looks like on an iphone/ipod before you launch it.

Start screen When you launch the application it requests the web service to fetch all the stores in the database. Starts with displaying a map with pins showing nearby grocery stores from the default location. Location services should be on; if not the user will be requested to turn on the services. Once you launch it, the application sends a request to the web service and asks for the list of stores in the form of a PHP script and then the web service queries the database in the form of an SQL query and fetches all the stores which are there in the database. These stores are sent to the application in by the web service by converting it in XML format. The app starts with displaying a map with pins dropped on it showing the nearby grocery stores from the default location. Now there is an option of setting the default location which I am gonna show you in the next slide. Now the option of the location services should be on from the phone settings.

Application settings Default latitude and longitude can be changed through the settings. There is an option of changing the search radius.

Product list On clicking a grocery store the web service reads the storeid from the request URL sent by the application through GET method of PHP. Appropriate query is executed and the list of products and corresponding coupons are fetched. The result of the query is changed into XML format and sent to the application. Once the user clicks a grocery store he wants the list of products associated with that store. So on clicking the store the client sends the storeid to the web service in the request URL and this storeid is read by the webservice through the GET method of PHP in the second php script which we have written. Now the service queries the database accordingly in the form of an sql query and fetches a list of products along with the coupon information specific to that store. The challenge was to covert the results of a SQL query to the XML format. After lots of reading and research, we came across different methods. We implemented a function in PHP to convert the results to the XML format. There were various automated methods available, but we chose to write a function for the conversion. The function is called ‘sqltoxml’.

Viewing Coupons By selecting the required products in the list, the list is ready to shop. There is an option of viewing the coupon specific to a product in form of an image. Once the user gets a list of products the user can select the products which are required and the list is ready to be shopped. We had an option of saving the coupon as form of an image or as a form of URL. From the perspective of performance we chose to save the URL of the coupon instead of the image as it would have naturally occupied more space and time to load on the screen.

Products sorted as per their aisle The products which were selected get sorted according to their aisle and get populated in the list. These products are ready to be shopped. Once the user selects all the products which he needs these products get sorted according to their aisle.

Adding a product When the user goes through the list of products available for a particular store and if he does not find something he still needs it there is a provision in this application to add a new product and save to the final shopping list.
