Website backend management system framework (beautiful and practical) PC version

Publish the background management framework of a website. The source author is not myself. The website background management system framework is just borrowed and modified, and it feels quite practical. It is just a background framework implemented by an Access database. It is relatively elegant and practical and can realize multi-level menus. Control and combine with js to dynamically display the background address: manage/default.aspx. There is no other content in the front desk. manage/DB_CNZZ/freasy.mdb is an Access database file. A very beautiful and practical background menu. Debugging Tips: This program requires .net3.5 environment support. ~
