n-tier development

[lfc77]

Does anyone know of any links/books so that I can learn about n-tier development in ASP.NET/C#?


Any help would be really appreciated.


Cheers,

n-Tier development is mostly about discipline.

You want to have each layer do only a small part of the application.

The data layer is closely tied to the database, and enforces referential integrity and does only inserts, updates, & deletes. The business logic layer enforces business rules ("to add a customer, you must have these values") and permissions ("to add a customer, you must have the add-customer permission flag"). The boundary layers aggregate information from various layers and presents the data in a format that the front-end layers (screen, web-service, import/export) can understand. The front-end layers do nothing but format the data.

Where people get in trouble is when they try and get each layer to do too much. The simpler the better, and the more scalable your application will be.

Thanks Chip. What I am really looking for is a good example that I can learn from, either in a book or on the net. I know the basics of OO, but I'm no expert and would learn a lot by following through an example of a real life application using an n-tier architecture.
