My LINQ Practice 1: Using liniq to transform the job site Starter Kit

I personally think job site starter kit is a good example website with simple structure and practical business (Talent network). Many books use it for demo, such as Asp.net Ajax.ProgramDesign book 1. To practice LINQ and increase the practical experience of using liniq, I plan to implement the Dal of this project using LINQ on my own.

 

Some of the following are some of its understandings:

1. UI Layer implementation: Use objectdatasource to bind the model class. Command mainly calls the crud method of the model.
2. Business Model & logic layer implementation: All attributes (dummy objects) and crud methods (service methods) are defined in the model object. The dbaccess object of dal is called during implementation, and objects such as sqlparameter (with SQLCode, Cannot be regarded as a strict Layer 3)
3. Data access layer implementation: A dataaccess class, acting like sqlhelper.

You can also use it to practice Ajax and membership provider.
