data level refers to asp Net, including data layer, business logic layer and presentation layer.
Using asp Net technology is often used to develop large and medium-sized applications. Among them, the operation of the database is encapsulated in the data layer, and the logical operation of the data is encapsulated in the business logic layer. The above two layers adopt Net class library, web form pages and user controls are in the presentation layer.
