Ex. No.1 ONLINE COURSE RESERVATIONDate:

AIMTo analyze, design and develop code for Online Course Reservation System using Rational

Rose software

PROBLEM STATEMENTAs the head of information systems for a college, you are tasked with developing a new

student registration system. The college would like a new client-server system to replace its much older system developed around main frame technology. The new system will allow students to register for courses and view report cards from PCs attached to the campus LAN. Professors will be able to access the system to sign up to teach courses as well as record grades.

Students may request a course catalogue containing list of course offering for all college. Information about each course, such as professor, department and prerequisites, will be included to help students make informed decisions.

Once the registration process is completed for the student, the registration system sends information to the billing system so that the student can be billed for the course.

OVERALL DESCRIPTIONThe Online Course Reservation System is an integrated system that has four modules as part

of it. The four modules are,

1) Login for Student: Using this module student login to the system using his/her unique username and password

2) Student Registration: In this module, the students register his/her details in the system. The details are stored in students table in database

3) Form for Registration: In this module the user can apply for the course by giving the details about the candidate and selecting the quota for the registration.

4) Enquiry about course: In this module the student can enquiry about the various courses in all the colleges.

Ex. No. 2 E- TICKETINGDate:

AIMTo analyze, design and develop code E-Ticketing using Rational Rose software.

Problem Statement

Our project is carried out to develop software for online Railway Reservation System. The software is coded in VB, which is the front end, and it has Back end, which contains information about the reservation and the availability of seats in trains. It has various options like reservation, cancellation and to view details about available seats. Our project mainly simulates the role of a Railway ticket booking officer, in a computerized way.

The reservation option enables a person to reserve for a ticket at their home itself. All he/ she has to do is to just login and enter the required details. After this the reservation database is updated with the person details, train name and also the source and destination place.

The cancellation option enables the passenger to cancel the tickets that has been already booked by him/her.

The availability option prompts the person to enter train number, train name and date of travel. After this the availability database is accessed and available positions are produced.

OVERALL DESCRIPTION:The E-Ticketing System is an integrated system that has four modules as part of it. The four modules are,

1) Viewing Train Details: To view the train details. Details can be viewed by giving the train number or Source and Destination

2) Checking Availability of Tickets: To view number of tickets available in the train3) Reservation of Tickets: To enable the users to reserve the tickets easily4) Cancellation of Tickets: To enable the users to cancel the tickets by giving PNR No

Ex No: 3 CREDIT CARD PROCESSINGDate:

AIMTo analyze, design and develop code for Credit Card Processing System using Rational Rose

software

PROBLEM STATEMENTWe envision a banking system that provides the customer holing a bank credit card can make

deposits, withdraws, check balances and perform transfer to and from their accounts. Credit card processing will be attractive to banking customer because they allow access to their accounts outside of regular business hours. Participating Banks want to make sure the access to their customer account information is safe and secure transaction information is accurate and reliable. Bank Customer-Want easy, low-cost, remote access to their accounts, but want to be assured that their accounts are secure and not accessible to hackers or other their parties. Bank must be able to handle multiple simultaneous transactions (and possible simultaneous transaction to the same joint account).Bank owning a credit card must be able to determine the cash on hand in the creditcard. The cash in the creditcard must be secure.

OVERALL DESCRIPTIONThe Credit Card Processing System is an integrated system that has four modules as part of

it. The four modules are,1) User Login: Using this module user login to the system using his/her unique username and

password 2) Withdraw: The purpose of this module to withdraw money from the account3) Deposit: The purpose of this module to deposit money to the account4) Balance Enquiry: Using this module the user can check his/her account balance and the loan

amount to pay if any.

Ex.No:7 STOCK MAINTENANCE SYSTEMDate :

AIM:To analyze, design and develop code for Stock maintenance system using Rational Rose

software.

PROBLEM DOMAIN:Stock maintenance system is a real time application used in the merchant’s day to day

system. This is a database to store the transaction that takes places between the Manufacturer, Dealer and the Shop Keeper that includes stock inward and stock outward with reference to the dealer. Here we assume our self as the Dealer and proceed with the transaction as follows:

The Manufacturer is the producer of the items and it contains the necessary information of the item such as price per item, Date of manufacture, best before use, Number of Item available and their Company Address. The Dealer is the secondary source of an Item and he purchases Item from the manufacturer by requesting the required Item with its corresponding Company Name and the Number of Items required.

OVERALL DESCRIPTION:1) Login Form: Authenticate the user and administrator.2) Department Selection Form: This form will give the options for selecting the department to

get knowledge about the conference.3) Conference view Form: This form contains the details about the conferences are conducting

by various institutions and we can see the date and time for the conference.4) Database Form: The details about the conferences going to conduct by various institutions.

Administrator can add the details about the conference for the students and also for the staff members.

Ex No: 10 ATM SYSTEMDate:

AIMTo analyze, design and develop code for Atm System using Rational Rose software

PROBLEM STATEMENTWe envision a banking system that provides the customer holing a bank credit card can make

deposits, withdraws, check balances and perform transfer to and from their accounts. Atm card processing will be attractive to banking customer because they allow access to their accounts outside of regular business hours. Participating Banks want to make sure the access to their customer account information is safe and secure transaction information is accurate and reliable. Bank Customer-Want easy, low-cost, remote access to their accounts, but want to be assured that their accounts are secure and not accessible to hackers or other their parties. Bank must be able to handle multiple simultaneous transactions (and possible simultaneous transaction to the same joint account).Bank owning a credit card must be able to determine the cash on hand in the atm. The cash in the at must be secure.

OVERALL DESCRIPTIONThe Atm System is an integrated system that has four modules as part of it. The four modules

are,1) User Login: Using this module user login to the system using his/her unique username

and password 2) Withdraw: The purpose of this module to withdraw money from the account3) Deposit: The purpose of this module to deposit money to the account4) Balance Enquiry: Using this module the user can check his/her account balance and the

loan amount to pay if any.
