EX NO 1: LIBRARY SYSTEM
AIM:
To generate the UML diagram for library management system
ALGORITHM:
MODULE 1:
• Provide a user interface for getting the user’s login details.
• Verify login ID and if correct, provide access to the library database.
MODULE 2:
• Provide a search mechanism to search for a particular book.
• Input the book name and the author’s name.
MODULE 3:
• Get the book details from the database.
• Display the book details on the screen.
MODULE 4:
• Allow the user to select the book for checking out.
• Issue the book.

Ex No : 3 QUIZ SYSTEM
AIM:
To generate the UML diagram for Quiz system.
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).

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.

Fig(2): Sequence diagram for Quiz System
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).
Fig(3):Class diagram for Quiz system
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.
16
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.

EX NO 4 STUDENT MARKS ANALYZING SYSTEM
AIM:
To generate the UML diagram for Student Mark Analyzing system.
ALGORITHM:
MODULE 1:
The system gets the application registration form.
The system gets the data from the user and checks for validity.
MODULE 2:
If the form is valid then the system checks for correction of data with respect to
the respective colleges database.
The form checks for eligibility criteria.
MODULE 3:
If the form is valid and eligible and there is no reduction in the given data then the
unique registration id, and hall ticket is issued to the applicant.
If the form entries are invalid then the application form is rejected.

EX NO 5 ONLINE TICKET RESERVATION SYSTEM
AIM :
To generate the UML diagram for Online Ticket Reservation System
ALGORITHM:
MODULE 1:
The user logs into the website using their id and password.

Ex No 6 STOCK MAINTENANCE SYSTEM
AIM:
To represent the stock management system using UML diagrams.The system
consists of three modules namely product supply, product storage and product order.
ALGORITHM
MODULE 1:
The supplier gets the list of products required from the warehouses.
The products are supplied based on the received list.
MODULE 2:
The warehouses stores the products sent by the supplier.
The warehouse manager is responsible for the mangement of the products in the
warehouses.
MODULE 3:
The supermarket sends a product order to the warehouses.
If the products are available, then the products are delivered to the supermarket.
