Chapter 15, Problem 41RQ
Explanation of Solution
In Oracle, database schema refers to the database system structure that is outlined in a formal language assisted by the database management system.
- The term database schema is also known as “SQL Schema”.
- Schema is generally a structure that consists of definition of objects constructed by a user, like views, base tales, and constraints as part of a database...

A Personal Address Book application program allows the user to add, delete, search, save, and
load contact information. The program separates the user interface (command-line) and the
internal processing subsystem. The internal processing system consists of the following classes:
•
•
Contact Manager (responsible for add and delete operations)
Contact Finder (responsible for the search operation)
pataManager (responsible for save and load operations)
a. What design pattern can be used to implement the user interface? Explain your answer using a
class diagram for the entire system.
b. Draw a UML sequence diagram to show the behavioral view of the Personal Address Book
program, demonstrating what happens when a user enters new contact information.
A system comprises three components: A, B, and C. Calling A requires calling B, and calling B
requires calling A. Component C is responsible for dissimilar tasks T#1, #2, and T#3.
a. Comment on the modifiability of this system. What problems do you see in this system, and
how would you solve them?
b. Suppose that T#1 is performed by both component A and C. What does this indicate about A
and C? How would you solve this problem?

- In a client-server system for a hypothetical banking application, the clients are ATM machines, and the server is the bank server. Suppose the client has two operations: withdraw and deposit. Use the broker architectural pattern to document an initial architecture design for this system: a. Draw a class diagram for this system. Use a client-side proxy to encrypt the data using an encrypt operation and a server-side proxy to decrypt the data. b. Discuss how you plan to apply redundancy tactics on the server. Additionally, identify the quality attribute that this tactic will achieve and discuss any potential side effects of applying it.arrow_forwarda. Comment on how you would achieve higher performance for a hypothetical Trent Course Registration System, assuming it utilizes a client-server architecture. b. Suppose we want greater availability of the server. Discuss what kind of tactics should be used to achieve that.arrow_forwardImplement a C program to find the largest element in a given array. You must have a main function and a max function. The function int main() will declare an array with the values {12, 100, 10, 1000, 20, 5}. This array will be passed to the max function. The function int max() will perform the necessary operations to find the largest element of the array. After max () is finished, have main () print the largest value and its index in the array. Do not hard code your solution! If we test your code with different array values, we should still get the correct output.
