Introduction
Purpose
The main purpose of this software is to reduce the manual errors
involved in the airline reservation process and make it convenient for the
customers to book the flights as when they require such that they can utilize
this software to make reservations, modify reservations or cancel a
particular reservation.
Product Scope
The name of the software is “AIRLINE RESERVATION SYSTEM”. This
software provides options for viewing different flights available with
different timings for a particular date and provides customers with the
facility to book a ticket, modify or cancel a particular reservation but it
does not provide the customers with details of cost of the ticket. Further, it
does allow the customer to modify a particular part(personal details) of his
reservation .
Design and Implementation Constraints
Regulatory policies: It is a mandatory that it contains no insufficient
data.The s/w should be accessible by multiusers at the same time.
Hardware limitations: There must be a 64 MB on board memory
Control functions: The software must be very user-friendly and
display appropriate error messages.
Interfaces to other applications: Not applicable.
Parallel operations: It must support many users simultaneously.
Reliability requirements: Data redundancy and use of special/blank
characters must be avoided.
Safety/security considerations: The application must be exited
always normally.
Higher order language requirements: VB.
Performance Requirements
At any instant, a maximum of four nodes or users will be given access
simultaneously.
Since the program handles multiple users, if more than one person
attempts to same date to the files stored in the data base, the
program will lock the data file using a 2-phase commit protocol to
prevent simultaneous access.
