Question 6 In order to make it easier to compare the relation scheme diagram to the UML diagram, we (check all that apply): ✓ If we realize that we forgot any attributes, we just add them in to the relation scheme diagram. ✔The order of the attributes in the relation scheme mirrors the order in the UML class. Name the relation schemes the plural form of the UML class name. Attribute names in the relation scheme diagram use snake_case.

Attributes from the identifying entity set's main key may be added to a weak entity set to make it strong. Please describe the overlap that will develop as a result of our choice.

QUESTION 3 A functor is a function symbol that names the relationship, but the name can be anything as long as it's a valid identifier. True False

Relationships in a use case diagram are a powerful mechanism to organize and reuse requirements. There are three main types of relationships in use case diagrams:1.Actor to actor—This is the generalization relationship and represented by the inheritance arrow in Figure 6.1. This relationship was also discussed in the previous chapter (notably Figure 5.3).2.Actor to use case—The relationship between an actor and a use case is called an association, also occasionally called "communication" because it represents a communication between the actor and the system. This association is represented by a straight line in Figure 6.1. The association is an interface through which an actor interacts with the system. Occasionally, an association line may have an arrowhead (not shown in Figure 6.1), representing the actor initiating the use case. This direction on the association relationship is only shown if absolutely necessary.3.Use case to use case—There are three specific relationships permitted…

Despite their importance, selection structures cannot complete the job on their own. All of us have to deal with the circumstance of having to repeat a succession of statements for various customers or transactions, or for online clients, at some point. To what extent do these jobs need certain types of frameworks? In what way are they different?
