國立東華大學資訊管理學系資料庫管理試題 Wei-Pang Yang, IM.NDHU, /6/20 Final Test-1 Suppose we have a relationship set borrower between customer and loan as shown in Figure 1. a)Draw an E-R Diagram for the application system in Figure 1. (Please show the mapping cardinalities.) b)What does it mean by the total participator, and which one is it? c)What does it mean by the partial participator, and which one is it? d)Reduce E-R model in a) to relational tables. Question 1: E-R Model (20%) customerloan E1 E2 E3 E Relationship Set: borrower Figure 1.

國立東華大學資訊管理學系資料庫管理試題 Wei-Pang Yang, IM.NDHU, /6/20 Final Test-2 Explain the following terms a)blob b)clob c)Integrity Constraints d) e) f)Weak Entity g)Build-in Data Types in SQL h)Specialization vs. Generalization in E-R diagram i)UML Diagram j)Update Anomalies! Question 2: Explain Terms (30%) grant on to EXEC SQL END-EXEC

國立東華大學資訊管理學系資料庫管理試題 Wei-Pang Yang, IM.NDHU, /6/20 Final Test-3 a)When we delete a tuple in branch, eg. Brighton Broklyn , what will happen in account? create table account (account-number char(10), branch-name char(15), balance integer, primary key (account-number), foreign key (branch-name) references branch on delete set null on update cascade ) 5. account 1. branch references Question 3: Referential Integrity (25%) b) When we update the first tuple in branch, eg. Donghwa Broklyn , what will happen in account? c) When we delete the first tuple in account, what will happen in branch?

國立東華大學資訊管理學系資料庫管理試題 Wei-Pang Yang, IM.NDHU, /6/20 Final Test-4 According to your final project as “Design and implement a useful database application system” a)What is the title of your project? b)Names of members in your team. c)Draw the E-R Diagram of your application system. (You can just give a similar diagram.) d)Draw a table to show one relation used in the system e)Check your answer in d) to see whether it is in the 1NF? Why? Please answer “ why ” by using the definition of the 1NF. f)Same as e) to see whether it is in the 2NF? Why? g)Same as e) to see whether it is in the 3NF? Why? Question 4: About Your Final Term Project (25%)
