Hint: 试利Template Class的用法. template<class Item, class Value, int Buckets> class Map{ public: virtual Boolean bind(const Item&, const Value&); virtual Boolean isBound(const Item&) const; }; m: Map<Customer, Order, 3> (6) (8%) For each of the following relationships: <<access>, <<import>>, <<extend>>, and <<include>>, depict a diagram to briefly illustrate their usages. 试画出一Diagram来说明<<access>>, <<import>>, <<extend>>, and <<include>> 的用法. (7) (2%) Please explain the definition of "mixin" defined in the "Generalization" relationship. 请解释Generalization关系中的mixin的定义？ (8) (8%) Please elaborate the definitions for "Navigation", "Visibility", "Qualification", and "Interface Specifier" in advanced associations. 请说明advanced associations中的"Navigation", "Visibility", "Qualification", 以及"Interface Specifier"之定义。 (9) (6%) Please elaborate the difinitions for "Anonymous Instance", "Orphan Instance", and "Prototypical Instance". 请说明"Anonymous Instance", "Orphan Instance", 以及"Prototypical Instance" 之定义。 (10) (15%) Given the following problem statements, depict a Use Case diagram that satisfies these statements. 请画出学生选课系统的 use case diagram 以满足底下所述的 statement。针对其中 一use case，画出其对应之 main flow of events。 (S1) You are asked to design a "Student Registration System". (S2) The new system will allow students to access the system, to register for courses and view report cards form personal computer attached to the campus LAN. (S3) Professors will be able to access the system to sign up to teach courses as well as record grades. (S4) Due to a decrease in federal funding, the college cannot afford to replace the entire system at once. The college will keep the existing course catalog database where all course information is maintained. The performance of the database is rather poor, so the new system must insure that access to the data on the legacy system occurs in a timely manner. The new system will access course information from the database but will not update it. (S5) The register's office will continue to maintain course information through another system. (S6) Once the registration process is completed for a student, the registration sends information to the billing system so the student can be billed for the semester. (S7) Since student grades are sensitive information, the system must employ extra security measures to prevent unauthorized access. (11) (6%) Please draw a sequence diagram based on the following collaboration diagram. 请将下面的Collaboration diagram转换成对应的Sequence diagram? http://w.csie.org/~b97133/course/UML_final.png (12) (5%) Consider the problem of modeling the behavior of an ATM. There are three basic states in which this sytem might be: 请画出 Statechart diagram 来满足下面所述一个ATM machine 的 statement 。 ‧ Idle (waiting for customer interaction), ‧ Active (handling a customer's transaction), and ‧ Maintenance (perhaps having its cash store replenished) Given the following problem statements, depict a Statechart diagram that satisfies these statements. S1. The state of the ATM changes from Idle to Active when the customer enters a credit card in the machine. S2. The customer might decide to cancel the transaction, returning the ATM to its Idle state. S3. While Active, the behavior of the ATM follows a simple path: ‧ Validate the customer → select a transaction → process the transaction → print a receipt → the ATM returns to the Idle state. ‧ You might represent these stages of behavior as the states Validating, Selecting, Processing, and Printing. ‧ It would even be desirable to let the customer select and process multiple transactions after Validating the account and before Printing a final receipt. S4. After Printing, there's a triggerless transition back to the Idle state. Notice that the Active state has an exit action, which ejects the customer's credit card. S5. The state of the ATM changes from Idle to Maintenance when Administrator maintains the ATM machine. S6. The state of the ATM changes from Maintenance to Idle after Administrator maintains the ATM machine. --
