All parts of the question must be answered in one place only :

Unit – I

Unit – II

3. The Web Customer uses some web site to make purchases online. Typically the website may have top level menus such as View Items, Make Purchase and Register. View Items could be used by customer only when they want to find and see some products. Register menu allows customer to register on the web site, for example to get some coupons or be invited to private sales. Customer may search for items, browse catalog, view items recommended for him/her, add items to shopping cart or wish list. Note, that the customers checkout after making purchase. Customer Authentication is included in View Recommended Items and Add to shopping cart. Design a use case diagram for online shopping system. 15M

4. a) Facebook uses OAuth 2.0 protocol framework which enables web application (called “client”), which is usually not the FB resource owner but is acting on the FB user’s behalf, to request access to resources controlled by the FB user and hosted by the FB server. Instead of using the FB user credentials to access protected resources, the web application obtains an access token. Web application should be registered by Facebook to have an application ID (client_id) and secret (client_secret).

When request to some protected Facebook resources is received, web browser (“user agent”) is redirected to Facebook’s authorization server with application ID and the URL the user should be redirected back to after the authorization process. User receives back Request for Permission form. If the user authorizes the application to get his/her data, Facebook authorization server redirects back to the URI that was specified before together with authorization code (“verification string”).

The authorization code can be exchanged by web application for an OAuth access token. If web application obtains the access token for a FB user, it can perform authorized requests on behalf of that FB user by including the access token in the Facebook Graph API requests. If the user did not authorize web application, Facebook issues redirect request to the URI specified before and adds the error_reason parameter to notify the web application that authorization request was denied. Design a sequence diagram for the above scenario. 10M

b) Engine is part-of Car or Car has Engine as main part hence the relationship between them is Composition. Organization has Person as employees, relationship between them is Aggregation. Write Java Class Skelton to demonstrate these concepts. 5M
