This document summarizes Jonathan Terry's .NET course work for a library management system created over three phases. Phase I involved building a Windows forms application to add members, check in/out books. Phase II added business and data access tiers using an n-tier architecture. Phase III transformed the application into a web application using ASP.NET, adding functionality like highlighting overdue books and converting juvenile to adult members aged 18+. The code examples show implementing validation, error handling, and interacting with the database using stored procedures across the different tiers and phases of the project.
