  3. 3. Library Project Phase 1Web Application Front-EndIntroduction:In phase 1, the goal was to design and develop a front-end web application for interacting with the librarysystem. The web application will utilize the provided assemblies: Business Layer and Data Access Layer, towork with the library system.Project Goals:To design and develop a user interface for:● adding new members● checking books in, checking books out● looking up members information● viewing what items have been loaned out to a member.Provide validations for member input and book input.Adult member can be added to Adult and Member tables.Juvenile member can be added to Juvenile and Member tables.Provide error-handlingOverdue books must be highlighted.AJAX Update Panel or AJAX Toolkit controls must be used at least once.Librarians must be authenticated into the web application.Forms-based authentication and authorization must be used.

  11. 11. Library Project Phase 2Business LayerIntroduction:For this phase, the assemblies provided to support the user interface in Phase 1 will then be replaced bythe assemblies that will be developed in this phase.Project Goals:Use LINQ to Entities to implement data access logic for querying and updating the database.Use at least two T-SQL stored procedures.Provide error-handling and business rule validations.

  15. 15. Library Project Phase 3WCF ServiceIntroduction:The library system must now be interoperable with other systems. My task was to provide a concept system thatutilizes Web Services and Silverlight. WCF was used to implement the service.Project Goals:Create a WCF Service that calls into the business layer.The WCF Service must support he ff:WsHttpBindingWebsite must be hosted in IISWebsite must use Secured Socket Layer SSL, and a self-signed server certificateUpdate the presentation layer to call the WCF service.Use DataContracts for all classes passed between client and host.Create a Silverlight web page to display information on overdue books.The Silverlight web page must use WCF to download overdue book data and display data in the browser.

  20. 20. Final ProjectIntroduction:In the previous phase, not all functionality that the Librarian needed were provided. In this final project, morelibrary functionality were added.Project Goals:Design and develop a front-end web application to include:Search function must allow to search by name, address, or member ID.Edit function may edit the name, address, birthday and may change sponsor for juvenile member.Renew membershipPromote juvenile to adult membershipUse LINQ to Entities to implement data access logicValidate all user inputProvide error-handling featureAJAX Update Panel or AJAX Toolkit controls must be used
