Free hosting Asp.net website universal backend management system v3.2

The free host backend management system is a universal backend management system. The reason why the word "host" is added to it is because the system itself does not have its own database and must rely on other databases to run. Freedom refers to The system is highly flexible and can achieve the desired functions after some simple configuration according to the database table structure. To put it simply, the system is not designed based on a specific database. It will do whatever structure of the database table you put on it.

The features of the free-hosted Asp.net website universal backend management system are as follows:
1. The backend itself does not have a database. After designing the database yourself, connect it to the backend. After configuring the nodes, you can directly add, delete, modify, and query the database without secondary development;

3. The background editing interface can automatically generate an editor according to the configuration, and also automatically generate a verification script;
4. The background supports multi-table association, and the corresponding content will be automatically displayed based on the associated fields during list query;
5. Compatible with IE6+, Firefox and other mainstream browsers;
6. Operations on database tables, such as addition, deletion, modification, and query operations, only require simple settings to complete without any coding.
