ObjectiveBuild parts of the business tier for a retail company. To achieve this two Assemblies were created: Foundation and AppTypes.

SummaryThis project demonstrated the use of OOP techniques and the .NET framework. Some of the techniques implemented into this project include:

Exception Handling. (using pre existing exceptions and building custom exceptions). Inheritance, Polymorphism, Encapsulation Abstract Classes and Interfaces Events and Delegates Serialization Generic Collections Creating and implementing custom Enumerators Properties Enumeration Creating and implementing custom attributes

ObjectiveCreate a Windows Forms-based front-end application that will provide a librarian with a visual interface through which the librarian may perform the desired functions. Required functionality included checking in and out books from the library as well as adding new members (adult or juvenile).

SummaryThis project demonstrates the use of .NET Windows form based development techniques. Some of the techniques implemented into this project include:

N-tier based architecture for scalability. User input validation and feedback using error providers. User input validation using regular expressions. Exception and Error handling. Implementation of a UI that requires minimal training for Librarians.

ObjectiveIn the Phase 1 project we were given the data access layer and created the presentation layer which interfaced with the Data access layer via the Business logic layer. In Phase 2, we recreated the Data Access Layer which consisted of the various Entities used by the application layers.

SummaryThis project demonstrates the use of ADO.NET, LINQ as well as ORM (Object Relational Modeling). Transact-SQL was also used to access the database, which was managed using SQL-Server 2008. Some of the techniques implemented into this project include:

Recreate the Data Access Layer while keeping existing functionality within all other application layers. Implement error handling in SQL stored procedures. Process errors received from stored procedures in ADO.NET using SQL state codes returned by stored procedures. Creating stored procedures in Transact-SQL on SQL-Server 2008. Using LINQ to retrieve and process result sets (using the entities data context) Retrieve and process result sets returned from SQL stored procedures. Writing comprehensive test scripts for testing stored procedure functionality. Utilize strongly typed datasets based on result sets of stored procedures.

ObjectivePhase 3 represented the transition of the User interface from a windows forms application to a web based application using ASP.Net. In addition to the previous functionality implemented in the first 2 phases, new functionality was also implemented in phase 3 and are as follows:

Providing the Librarian with the ability to renew an adult members expired membership card. Automatically updating Juvenile members of the library to adult members if they have encountered or passed their

18th birthday.Providing the Librarian to add new books of additional copies of existing books into the library.

SummaryThis project demonstrates the use of ADO.NET and LINQ but has a core focus on ASP.NET. Some of the techniques implemented into this project include:

Create and use ASP.NET master pages to provide a more organized and consistent look and feel throughout the website.

Databinding gridviews through the use of an ObjectDataSource control. Utilizing various validation controls to validate user input before postbacks. Use of validation summaries to obtain user feedback to deal with input validation Utilizing ViewState and SessionState objects. Use of Membership Roles to restrict user access to pages.

ObjectiveThe main focus of this project was to add another layer to our Library management application as well as implement a WCF service. As the potential to acquire libraries and creating partnerships with others increases, we see the need to take the library system to the next level – allow interoperability with other systems. The web service, once implemented will allow for communication with these different systems but also allowing us to keep the application layers which already exist intact.

SummaryThis project demonstrates the use of the Windows Communication Foundation to implement web services . Some of the techniques implemented into this project include:

WCF services. Authorization using ASP.Net roles. Authentication using ASP.Net membership. Implementing Data Contracts into Data Access Layer Entities to allow Serialization across various application layers. Implementing Fault Exceptions and error handling.
