This document summarizes 5 .NET projects completed by Darian Lowe focused on developing different aspects of a library management system. Project 1 involved learning core .NET concepts. Projects 2-4 involved developing frontend, backend, and web-based versions of the system. Project 5 converted the system into a web service using WSE 3.0 and certificate authentication. The goals were to learn .NET and build out the full system across different tiers and platforms.

4. Description The project was required that the student complete all the requirements and run the test case program which would grade the correctness for each sections. The section cover were: Creating and working with interfaces Creating and working with Abstract classes Creating and working with Attributes Creating and working with Enum Creating and working with Events (Event Handlers) Creating and working with Delegates Creating and working with Collections Creating and working with Exceptions

5. SetFocus Project 2 Library Phase 1: Windows Front End Application Introduction: This project is have the developer create a common front end application for a SQL 2005 Server Library Database. The focus is to create a frontend application using Windows form in the C# .NET platform. This also introduces to the developer the three tiered approach to programming, Data Access Layer, Business Layer, and Front End (Presentation Layer). Audience: Developed for End User Project Goals: To complete the presentation (Front End) and business layer of a library database system.

7. Description As specified by the requirements a front end and business layer was developed to interface with a library database (SQL2005) using a given Data Access Layer in a dll form. As part of the requirements, We used several C# built in functions such as: Window Forms (MDI for housing multiple window forms) Window Controls including features of: Validating events RegEx for field validation DataGridView for displaying books on loan from a given DataSet

8. SetFocus Project 3 Library Phase 2: Business & Data Access Tiers Introduction: This project extends the previous project of Library Phase 1, in which the developer is required to design the Data Access, and Business Layer whilst reusing the Front End application developed in Phase 1. This project introduces SQL 2005 Stored Procedures, in which are created to access the various tables in the Library Database. Audience: Developed for End Users Project Goals: To complete the Required Data Access and Business Layers of the Library System and reuse the previously developed Front End.

9. Project Sample

10. Description This project requires that we design the back-end requirements for the library database as specified in the last project. We were required to create: MSQL2005 Stored Procedures, 10 Procedures Add Adult Member, Add Juvenile Member, Check in item, Check out item, Get Item, Get Items, Get Member, Get Member by ISBN, Convert Juvenile to Adult Member Business Layer and Data Access Layer using ADO 2.0 Access to SQL Server 2005 requires use of the Microsoft ADO 2.0. All requirements are written using C#

11. SetFocus Project 4 Library Phase 3: Web Application Introduction: In the continual development of the Library system, a Web Based Front End Application is developed using ASP.NET, Form based authentication is used, in which users and roles are stored on a SQL 2005 aspnetdb Database. Audience: Developed for End User Project Goals: To Develop a ASP.NET Web Application as a frontend using the existing Data and Business Access Layers created in Library Phase 2.

13. Description As specified by the requirements a front end Web Application was developed to interface with the existing Data and Business Access layer of the previous Library phase 2. As part of the requirements, We used several ASP.NET built in functions such as: ASP.NET built in Login ASP.NET built in validators (Required Field, Regular Expression, Range Validator etc) ASP.NET GridView for displaying books on loan from a given DataSet ASP.NET Sitemap Using Sessions for saving data due to page_load

14. SetFocus Project 5 Library Phase 5: Web Services Introduction: This project the developer is given a existing Web Client Application, Data and Business Layer Library system to convert into a Web Service using WSE 3.0 Audience: Developed for End User Project Goals: Convert Pre-existing Web Based System into a Web Services using WSE 3.0 and Certificates
