QUIZ SYSTEM AIM:

To implement the Quiz System using Rational Software.

ALGORITHM:

Step 1: Identify the Actors and Use cases.

In this system,the actors and use cases are:

Actors: User ,System and Database.

Use cases: Login,Option,answering questions,calculating marks and Display score

card.

Step 2: Build the relationship between actors and use cases.

The use case diagram for the quiz system is given in Fig(1).

Fig (1): Use case diagram for the Quiz System



2. ALGORITHM FOR SEQUENCE DIAGRAM:

Step 1: Identify the objects.

In this system, the objects are: User, System and Database.

Step 2: Identify the sequence of events.

Step 3: Login to the system to check the validity.

Step 4: Select the option in the system.

Step 5: Answer the questions for the selected options

Step 6: Evaluate the answer and calculate the mark.

Step 7: Save the score in the database.

Step 8: Display the score.

3. ALGORITHM FOR CLASS DIAGRAM:

Step 1: Create class diagram for each identified objects under sequence diagram.

Identified objects are: User, System and Database.

Step 2: Class diagram for each object is divided into three parts.

Top portion represents the Class Name.

Middle portion represents the Attributes.

Bottom portion represents the Methods.

The Class diagram for Quiz System is shown in Fig(3).

Procedure to write the software for the Quiz System using Rational Software tool

Selecting the Software:

1. Click start-> Rational Software->Rational Rose Enterprise Edition.

Create the project:

2. In the Create New Model window select VB6 Standard Framework->A screen appears;select

the untitled project from the browser window and save it

To draw the diagram:

3.Right Click the Use case view->New->Use case diagram->Sequence diagram->Class

diagram(name and save the files)

4. Click Use case diagram->using the tool box build the use case diagram.

5. Click Sequence diagram->using the tool box build the sequence diagram.

6. Click Class diagram-> using the tool box build the class diagram.



Generate the coding form:

7.Right click component view -> component diagram-> open specification -> select the

stereotype as DLL-> select the language as visual basic ->switch from general tab to realizes

tab-> select the classes you created in class diagram-> right click ->Assign->Ok.

8.Right click component view -> update code form model-> the tool window for converting

diagrams to code appears->next->finish->the skeleton code in VB is generated automatically

for the class diagram designed.

AIM

To implement the ATM System using Relational Software.

ALGORITHM

1. ALGORITHM FOR USE CASE DIAGRAM:

Step1: Identify the Actors and Use cases.

In the system, the actors and use cases are:

Actors: User, System and Database.

Use cases: Login, Deposit, withdrawal, updation, balance enquiry

Step2: Build the relationship between actors and Use cases.

The use case diagram for the expect system is given in Fig (1).

Fig (1): Use case diagram for the ATM System




Step1: Identify the objects.

In this System, the objects are: User, System and Database.

Step2: Identify the sequence of events.

Step3: Login to the system to check the validity.

Step4: Select the option in the system.

Step5: For the user to deposit or withdraw the amount ,they should enter the option in the

System.

Step6: The System will do the corresponding processing with proper Updation in the Database.

Step7: Finally the balance is displayed to the user.

The sequence diagram for ATM System is give4n in Fig(2).

STOCK MANAGEMENT SYSTEM

AIM:

To Implement the Stock Management System using Rational Software.

ALGORITHM:


Step 1: Identify the actors and use cases.

In this system, the actors and use cases are:

Actors : User, System and Database.

Use cases: Login, Product in, Product Delivery, Add New Product, Updation.

Step 2: Build the relationship between actors and use cases.

The use case diagram for the stock maintenance system is given in Fig(1).

Fig (1): Use Case Diagram for Stock Management System

Product-In

login

View Stock Details

User

Product-Out

Return Stock

Admin

Update & Modified





In this system, the objects are: user, system and database.


Step 3: Login to the system to check the system.

Step 4: The user request for in products in the system.

Step 5: System show the details by making query request in database.

Step 6: Then the user may request our product in the system and for that also it will

respond by requesting the database.

Step 7: And if the user request the new product, it will be added as a new product.

Step 8: Finally confirmation is given to the user for the request product.

The sequence diagram for stock maintenance system is given in Fig (2).



Fig (2): Sequence Diagram for Stock Management System


Step 1: Create class diagram for each identified object under sequence diagram.

Identified objects are: user ,system and database


Top portion represents the class name.

Middle portion represents the methods.


The class diagram for stock maintenance system is shown in Fig (3).



Fig (3): Class Diagram for Stock Management System

Procedure to write the software for the Stock Management System using

Rational Software.


1. Click start-> rational software -> rational rose enterprise edition.

Create the Project :

2. In the create new model window select vb6 standard framework -> A screen

appears; select the untitled project from the browser window and save it.


3. Right click the use case view -> new -> use diagram -> sequence diagram ->

class diagram (name and save the files)

4. Click use case diagram -> using the tool box build the USECASE diagram.

5. Click sequence diagram -> using the tool box build the SEQUENCE diagram.

6. Click class diagram -> using the tool box build the CLASS diagram.


7. Right click component view -> component diagram -> open specification ->

select the sterotype as DLL-> select the language as visual basic -> switch from

general tab to realize tab -> select the classes you created in class diagram ->

right click-> assign ->ok.

8. Right click component view-> update code fro model -> the tool window for

converting diagram to code appears -> next -> finish -> the skeleton code in VB is

generated automatically for the class diagram designed.
