Library Project Phase 1 – Create a Windows Forms front end C# application utilizing existing Business Logic and Data Access layers

Library Project Phase 2 – Develop replacement C# Business Logic and Data Access Layers; Develop Transact-SQL Stored Procedures

Library Project Phase 3 – Develop replacement front end ASP.NET Web application and add functionality

The three phased projects described herein built upon each other, utilizing additional and more complex tools.

Each was completed in one class week to meet assigned deadlines.

Library Project – Phase 1

Requirements:

• Design and develop a Windows form-based front end application that satisfies these basic functionalities: Get Member Information, Add Adult, Add Juvenile, Check In a book, Check Out a book.

• Produce a user interface that is intuitive, requiring minimal training for users while minimizing resource utilization.

• Include easily maintainable code, form-based field validation, and all required error handling.

Results:

• Received grade of 100%

• Sample screens and code follow

Get Member Information

• Main entry screen for application

• Menu links to all other screens

Get Member - Adult

Code Sample - Validation

Validate using Regular Expression or “Regex”

Code Sample - Formatting

Middle Initial is optional for both Adult and Juvenile

Members.

This common routine displays middle initial between first and last names only when present.

Code is organized into regions and well documented.

Library Project – Phase 2

Requirements:

• Design the Business and Data Access tiers (including T-SQL stored procedures and ADO.NET database access) to support the Phase 1 Windows front end.

• Include easily maintainable code, form-based field validation, and all required error handling.

• Use database-programming techniques that provide maximum programming flexibility and control while minimizing resource utilization.

Results:

• Received grade of 100%

• Sample screens and code follow

Modified Get Member Screen

Same basic screen layouts from Phase 1

Added functionality:

T-SQL Stored Procedures

Sample of comments at top of each procedure describing all input and

return values

T-SQL Stored Procedures

All procedures utilize

• Complete edits

• Defined Transactions with BEGIN and COMMIT

(or ROLLBACK)

C# ADO.NET Code Sample

Library Project – Phase 3
