ask a question:
(suppose) I want to be a mall in the cup industry, and then sell the mall to various cup merchants. My personal idea is to be a general mall, sharing a backstage and a set of databases. If there is a merchant who wants to customize the page, he will be paid to make a foreground template for him alone. The problem now is to assume that a merchant wants to customize the background function and this function conflicts with other functions, what should I do if forced to add it will affect other users? no, no, no. In fact, the question can also be reduced to whether I share a set of programs and a database, or a roughly equivalent set of programs + independent databases.
