On Monday afternoon, if you are in school now, you can drink a big afternoon tea, huh, huh.
Today, I have been watching the company's .NET SDK document, but still just started .NET, I feel a little confusion, huh, huh, organize.
Company .NET SDK divided 7-tier,
First layer: Web UI layer
Layer 2: BF-Business Forecase layer
Third layer: Br-business rule layer
Fourth floor: BM-Business Model layer
Fifth layer: DA-DATA Access layer, actually contains two layers of DA and DAF
Sixth floor: IF-Interface Forcase layer
Seventh floor: Database
Strictly speaking, this is not enough to be 7 floors because there is a parallel call, and there is no obvious hierarchy relationship.
