AN AUTOMATED TICKET ISSUING SYSTEM

In a railway station automated ticket issuing system should have the following requirements:

The system should be fast enough to handle huge amount of transaction.

System must have the ability to provide security.

AN AUTOMATED TICKET ISSUING SYSTEM

So, according to this requirements we have designed a system mentioning the following common steps:

1.System Structuring.2.Control Modeling.3.Module Decomposition.

System Structuring:

In system structuring we have used Client- Server model.

Why Choosing Client Server Model ? In client server model distribution of data is

fast and straight forward. This model utilize network model effectively. Client server model is more scalable than

other models. Here security is better than repository model.

Though abstract machine which uses layered architecture is also very secured but it is not perfect for this case.

Control Modeling:This modeling is of two types:1. Centralized control modeling2. Event driven control modeling

In our proposal we have applied centralized modeling. Because, in event driven control modeling, if the value of an event changes then all subsequent value also changes. So, this modeling is not appropriate here.

Centralized control modeling:

In this we have used call and return model.

Why choosing Call and Return Model?

Here each subsystem calls another subroutine, and finally when value is found, it returns the value to the caller.

In Manager model, full system is dependent to one manager, for this manager model is not appropriate here.

AN AUTOMATED TICKET ISSUING SYSTEM Module Decomposition:

There are two models in Module Decomposition:

1. Object Oriented 2. Data Flow

Here we have chosen Data Flow model for our proposal.

Why choosing Data Flow Model?

This model is straight forward and easy to understand.

Implementing data flow model is more easier than Object oriented model.

Changing object interface is Complicated and complex entities are hard to represent as object.
