Maintenance types and severity levels in Bus Reservation System

BUS RESERVATION SYSTEM

INTRODUCTION

Travelling is a large growing business across all contries. Bus Reservation System deals with maintenance of records of details of each passenger. It also includes maintenance of information like schedule and details of each bus. In the existing systems they have to do many works manually. It takes a lot of time and causing many errors while data entry. Due to this, sometimes a lot of problems occur and they were facing disputes with customers. To solve the above problem, and further maintaining records of passenger details, seat availability, price per seat and other things, we are offering this proposal of computerized reservation system.

PROBEM STATEMENT

Bus Reservation Systems that were suggested till now, are not up to the desired level. There is no single system which automates all the process.

In order to build the system, all the processes in the business should be studied, System study helps us under the problem and needs of the application. System study aims at establishing requests for the system to be acquired, development and installed. It involves studying and analyzing the ways of an organization currently processing the data to produce information. Analyzing the problem thoroughly forms the vital part of the system study. In system analysis, prevailing situation of problem is carefully examined by breaking them into sub problems. Problematic areas are identified and information is collected. Data gathering is essential to any analysis of requests. It is necessary that this analysis familiarizes the designer with objectives, activities and the function of the organization in which the system is to be implemented.

Existing system

·       Existing system is totally on book and thus a great amount of manual work has to be done. The amount of manual work increases exponentially with increase in services.

·       Needs a lot of working staff and extra attention on all the records.

·       In existing system, there are various problems like keeping records of items, seats available, prices of per/seat and fixing bill generation on each bill.

·       Finding out details regarding any information is very difficult, as the user has to go through all the books manually.

·       Major problem was lack of security.

Proposed system

The system is very simple in design and to implement. The system requires very low system resources and the system will work in almost all configurations. It has got following features:

·       Needs a lot of working staff and extra attention on all the records.

·       Ensure data accuracy.

·       Records are efficiently maintained by DBMS.

JTH COMPONENT REVIEW-2

A software has to be developed for automating the manual bus reservation system. The system should have distributed functionalities as described below.

1.RESERVE SEAT

A passenger should be able to reserve a seat in the train specified by him if available. For this he has to fill reservation form with the details about his journey. The clerk checks for the availability of the seat in the bus and if the seat available then he makes entries regarding bus name, bus number, date of journey, boarding station, destination.

2.CANCEL RESERVATION

There may arise a case when the passenger wants to cancel his reservation. For this he has to fill a cancellation form providing all details about the bus reserved by him. The clerk then checks for the entries from the database and cancels the reservation finally returning the ticket amount with some deduction.

3.LOGIN

Only the user with specified login id & password can get access the system. This provides security from unauthorized access.

4.      IEW RESERVATION STATUS

All the users should be able to see the information about the reservation status & bus schedule, train name, bus number.

TYPES OF MAINTENANCE

CORRECTIVE MAINTENANCE

It is reactive modification of a software product delievery to correct discovered problems.

PERFECTIVE MAINTENANCE

Is concerned with the change in the software that occurs while adding new functionalities in software.

ADAPTIVE MAINTENANCE

It is usable in a changed or changing environment. Adaptable to new environment such as to run software in different OS.

PERFECTIVE MAINTENANCE

Modification of a software product after delievery to detect and correct

latent faults.

Problems	Types of maintenance
After delievery of the BRS, inspite of correct username and password the system show invalid messages. Incorrect details in the view reservation status like bus number, destination etc. Incorrect information about the transcation the amount and refunding.	Corrective Maintenance

Adding of new functionalities into the system like update bus information and report generation will not cause any error to the system like slow performance, incorrect behavior etc. The system will perform same with the addition of new functionality.	Perfective Maintenance
The system should be able to run in any platform like android, desktop with different OS. The system able to perform the same in all the platforms. Some Functionalities should be supported in desktop and not supported in mobile phones this should be avoided. The system should be developed for both desktop and mobile application.	Adaptive Maintenance
Modification of a functionalities after delievering the system based on the user finding the errors when using the information. The user may find incorrect bahaviour of the system, wrong results etc	Preventive Maintenance

PROBLEM RESOLUTION
