Label:The first scenario:The use of recursive algorithms is also the most frequently used, most open-source programs are the same, but generally only use the level four classification. The database structure design of this algorithm is the simplest. A field ID in the Category table, a field FID (parent ID). This allows you to judge the top level of content based on where id = FID, using recursion to the topmost level.Analysis: Through this kind of database design
