The document summarizes a .NET developer's portfolio consisting of several library management system projects. The projects were developed across multiple phases, starting with a Windows desktop application and expanding to a web application, web service, and additional features. The final portfolio spanned 6 projects with over 10,000 lines of C# code to support a full-featured library system.

- 2. .NET Framework Project Build parts of the business tier for a retail company. Create and test two assemblies: The first assembly is a class library project called Foundation, containing various interfaces and base classes. The second assembly is a class library project called AppTypes, containing various entity, collection and exception classes.
- 3. Classes of Many Types Required
- 4. Sample Code
- 5. Library Database Project Introduction: A database has been created to support the principal functions of a lending library’s day to day operations: checking books in and out, and adding new members (adult and juvenile) Audience: Users of the library database (i.e. librarians). Project Goals: Provide an easy to use user interface to access and manipulate the data in the database.
- 6. Layered Architecture Data transport between layers using Entities User-friendly Interface. Menu driven Navigation. Well Covered Validations Design Highlights
- 7. Library Phase I Requirements: Develop a Windows front-end with four functions Add adult member Add juvenile member Check in an item Check out an item Two Projects Developed: Windows Client Form control Validation Business Layer Business layer enforcement Data access layer communication
- 8. Project Sample (Get Member Info) Can view member information Highlights out dated card expiration Highlights over due books
- 9. Project Sample (Add Adult Member) Combo box populated from XML file Icon and tool tip used to communicate errors
- 11. Library Phase II Develop stored procedures for seven processes: Add member Get member Check in an item Check out an item Get item (returns an item with a specific ISBN and copy #) Get items (returns all items a member has checked out) Convert juvenile to adult membership Create a data access layer: Call stored procedures in the database Return data or throw errors to the Business layer Create Entities classes accessible to all layers: Member AdultMember (derived from Member) JuvenileMember (derived from Member) Item ItemsDataSet LibraryException
- 12. ADO.NET code in Data Access Layer
- 14. Library Phase III Convert Windows interface to Web interface Add functionality: Add new item to the database (new ISBN or copy of existing ISBN) Ability to renew membership card Add Security: Add a Librarian role to the database with users Prevent everyone except the Librarian role from accessing library functions
- 15. Log-in screen on startup for security
- 16. All functionality from Windows UI remains in Web UI In addition, user has the option to renew an expired card
- 17. Use of validators to provide error checking
- 18. Sample code to add member to database
- 19. Library Phase IV Create a Web service that calls into the business layer Update the presentation (UI) layer to call the Web service Employ WSE 3.0 security using certificates Support previous project functionality
- 20. Sample code implementing the Web service
- 21. Summary Six projects (Framework, Library Phase I – IV, Evaluation Surveys (team project)) 10,000+ lines of C# code 1000+ lines of supporting code (SQL, XML, HTML) 240+ project hours
