1. Project: Data Access library Data access API: ADO.NET Language: C# Developer: Efoe CLUMSON-EKLU This project is the basis for other projects that I’ve completed at SetFocus LLc. It is the data access module that will be reused in the “public library project” a window & web application that help manage books loans and members transactions in a public library. The main objective of this project is to: • Design the Business and Data Access tiers • Develop code that is easily maintainable. • Provide adequate error handling. • Write Stored Procedures on the SQL Server database for the application’s interaction with data. • Use database-programming techniques that provide maximum programming flexibility and control while minimizing resource utilization

3. Sample codes: Entities.Member

4. Entities.Member

5. Sample codes: Entities.JuvenileMember

6. Sample codes: Entities.Item

7. Sample codes: Entities.LibraryException

8. Sample codes: DataAccess.LibraryDataAcces

9. LibraryDataAcces

10. Sample codes: Stored Procedures

11. Stored Procedures

12. Stored Procedures

13. Stored Procedures

14. Sample codes: BusinessLayer.LibraryBusiness

15. The business and data access layers built in this project will help on Later project such as the Windows and Web application versions of the “ Public Library” projects. As a reusable module, it saved a great deal of Work reinventing the wheel when creating the clients. On the database side, the stored procedures helped create a robust and More secured application. Overall, this project was a real experience that only made me a better Programmer.
