The purpose of the portfolio is to demonstrate my experience with C#/ASP.NET using a fictitious library project. The portfolio will not represent the library project in its entirety, but will provide screen and code behind snapshots for brevity that are representative of the skills required to create the project.

Public library is a fictitious library website that provides basic functions that are common to most websites a login, and a change password webpages. The register user has been replaced with an add librarian webpage since only librarians can use this website.Public library provides librarians the functionality to manage patrons allowing them to view, and add adult and juvenile patrons.Public library provides librarians the functionality to manage the items in the library by allowing them to view items.Public library provides librarians the functionality to manage library services allowing them to check in and check out items.Public library provides librarians with navigation capabilities by allowing them to use the menu, tree, and sitemap path controls

The Library Project is an N-Tier application consisting of a front-end website user interface, middle tier business objects, and a back-end SQL Server database.The front-end website uses standard website controls with user input validation and sitemap controls to navigate the website.The middle tier consists of business logic that determines the maximum items that can be borrowed, adding and retrieving members, determines if membership has expired, determine if member is a juvenile, retrieving library items, checking in items, and checking out items.The middle tier business layer uses LINQ and Data Transfer Objects (DTO) for database operations.The back-end tier uses tables to store membership, item, and loan history information.

The Public Library Check Out webpage gives librarians the functionality to allow patrons to check out library items.The patron member id is entered by the librarian and its validity is verified by the website.The library item ISBN and copy number is entered by the librarian and its validity is verified by the website.Before a library item is checked out the website gives the option for the librarian to back out of the operation.Before a library item is checked out, the website checks to see if the item is checked out or the library patron has exceeded the limit.
