Generate a TreeView tree structure based on the data table content. The common practice is to start from the top level, and then generate one by one recursive query traversal. This method is easy to implement and easy to think of, but it is inefficient because of Database Retrieval (SQL statements need to be interpreted and executed, and database files are operated) it is time-consuming, especially when there are many layers and nodes in the tree.
