C＃类库和报表

Question

I am building a big system, which i have divided in three tiers, UI, Class-Library, and Database. Database stores all data only, and Class-Library provides all functionalities and business logic. And UI is the User-Interface.

The issue which i face is: how to integrate the reporting in this situation. I am using C# for class-library, and windows-forms-in-C# for UI. I intend to use rdlc Microsoft reports.

My strategy at this point is: Let every object add its own data in a dataset, which will be then returned to the UI for display in report.

Answer 1

It seems to me that the reports are just another UI. Your business logic for what data to return for a given report should live in the class library. The reporting business objects would probably live in a namespace of their own (Appname.Reporting). I think I would have an abstract report class that provides a skeleton for most properties and methods that a report would need, and subclass that skeleton for each individual report. Thus, one class per report, but all derived from a generic class.
