Capture Business Rules

Functional requirements define what the system should do, business rules help define what needs to be done and how it is done.

Following is an example of Business rules for a library system

Business rules about borrowing

General borrowing rules:

 There is no maximum number of books that can be borrowed

 Books must be returned within 4 weeks

 Borrowers can borrow a maximum of 4 videos

 Videos must be returned within 2 weeks

 Borrowers can borrow a maximum of 4 CDs

 CDs must be returned within 2 weeks

 Borrowers are unable to borrow items if there are items overdue on the borrower’s account

 Borrowers are invoiced for items that have not been returned

When an item is loaned the following information is recorded:

 Borrowers ID

 Item ID

 Date borrowed

 Return due date

 The item is flagged as borrowed

When an item is returned the following information is updated:

 The item is flagged as returned

Business rules about customer applications for a borrower’s account

To become a borrower, customers must supply the following details:

 Name

 Address

 Phone number

 Age

 (Email address) – optional

 Each borrower has a unique identifier (ID)

Business rules about loan items

When new loan items are received at the library, the following details are recorded about each item:

 Unique identifier (ID)

 Title

 Author

 Subject category

 Media type

There are media types – Books, Videos, CD – for each of these media types we keep additional information

Your tasks:

Task 1 – Capture Business Rules

To represent business rules diagrammatically:

 Draw a Context Diagram showing basic business process and entities. (Structured modelling)

 Draw a Use Case Diagram showing all the actors and use cases. (Object oriented modelling)

Task 2 – Temperature Conversion

Write a program to convert Celsius Degree to Fahrenheit Degree, we declare c and f, and use these as follows:

double c; // Celsius degree

double f; // Fahrenheit degree

Temperature conversion formula as follows:

? = ? × 9

5 + 32

Task 3 – Class

Design a class name Circle to represent a circle. The class contains:

 Radius as data field

 Default constructor that create a circle with 1 unit radius

 A constructor that create a circle with specific radius

 The accessor(get) and mutator(set) functions for all the data field.

 A function named getDiameter() that returns diameter of the circle

 A function named getCircumference() that return circumference of the circle

Task 4 – Array

Write two overloaded functions that return the average of an array with the following headers:

int average(int array[], int size);

int average(double array[], int size);

Use {1, 2, 3, 4, 5, 6, 7, 8, 9} and {1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 7.5, 8.5, 9.5} to test the functions.

Task 5 – Binary search

From Task 3, create a function named binarySearch(int x) perform a binary search algorithm.

Task 6 – GUI

Create a C++ GUI Form, ask for 1 integer then perform a binary search in sample array from Task 4. The result displays on screen are a number of comparison and search result (Return item position if found, return -1 if not found)

Task 7 – Debugging

Use the code from Task 6, perform debugging, steps as following:

 Add 2 break points in binarySearch function

 Capture screen that show current variable value

Task 8 – Testing and Documenting

Once you have completed the development of the application, you need to test the application against the specification before handing over to your trainer. You also have to develop a user manual template on how to use a binary search software.

Task 9 – RAD tools

Write an essay (not more than 300 words) on the “Design Creeps” with this iterative design process using the RAD tool (PhormGen)
