As shown in figure I only know a use case is a login system management products query add but not sure the relationship between the cases I don't think this is the login and product management is inclusion relation, and product management and product queries and add excuse me, who can say it to me?

CodePudding user response:

Some people the answer is what ah

CodePudding user response:

This figure feel strange, login contains source legitimacy check, account password authentication, request, etc., product management is to login another operating level, just log in to the back (this is reflected in the flow diagram), the same product management into the query, add, etc., is a relationship, when using extension? Products are some stationery, for example, now there is some specific products to do some 3 d display, then add 3 d resources that is to add extensions,

To sum up, the object modeling language, UML model also so built to reflect the object-oriented thinking,

that, please login and product management there is no relationship between the two cases? Then the product management and query containment relationship is to add?

that drawing a line between user and login directly, the user and product management there is another line?
