ASP.NET-MVC Framework Review (10)-build project framework based on three-tier architecture and MVC

1. Three modes of comparison

I. MVC framework (for large projects)

1.V View (Web page section)

2.M Models (business logic + data access + entity classes)

3.C Controller (between M and V, plays a guiding role)

Two or three-tier architecture

1.UI (Web page, form)

2.BLL (business logic, only logic code, no data access code)

3.DAL (data access, Access data source)

Models (Entity class: Used to encapsulate data, which is the carrier of data)

Three or three-tier architecture +mvc

V

C

M (BLL +dal+models)

Three-tier architecture +MVC combined Application Mode

2. Three-tier architecture +MVC portfolio development Steps:

(1) Creating an MVC Project
