If the database is queried every time you enter the page and the page content is generated, the website performance will be very poor if the access volume is very large, if the page content is generated only when the database is queried for the first access.

I've been developing Web applications using the ASP. WebForm framework for almost four years, and throughout my development career, I've used the MVC framework of ASP. Because there is often a discussion on the WebForm framework and the MVC framework of the pros and cons, so they are also concerned about the two, because they are most familiar with the WebForm fr

asp.net webform and asp.net mvc (MVC for short) are based on the ASP.net web development framework, one of the big differences is that MVC focuses more on the HTTP nature, and WebForm tries to block HTTP by providing a number of server controls and viewstate mechanisms that allow developers to develop windows Form applications, programming based on the event model. Both have pros and cons and app
His own understanding of MVC is more difficult to learn than WebForm, but performance is better than WebForm, which is more suitable for large projects, higher cost of development, but low coupling, easy maintenance, not too many off-the-shelf controls, and less development efficiency.
