ACKNOWLEDGEMENT

A thanks giving is not just a formality but it is the way to express our gratitude towards all the

people who have been a source of information and have guided us at every step of this

assignment. I have tried to give my best effort to Gather information, analyze, categorize to

complete project in the best way.

This assignment gave me the opportunity to get an upper hand in Concurrent Systems Designs.

I learned how to develop FSP and LTS which helped me enhance my critical abilities. I also

got an exposure to the programming techniques in Java where I learned to apply client server

architecture in Online Railway Reservation System which will prove to be beneficial to

me. I devoted a great deal of time working and developing this project.

I am thankful to the management of APIIT for giving us such an opportunity. I would like to

give my deep gratitude to our project and Module Coordinator, Mrs. Sonia Arora for giving

his attention to overview the entire manuscript of the project. At last but not the least, I thank

my colleagues and my seniors who assisted and regularly criticized at several points.

Thanks to all

INTRODUCTION

In todays world of globalization, need for taking business online is increasing day by day. People

from the corporate world salivate with anticipation with idea of having an e-commerce website and

automated client server architecture based systems for themselves. The business world require

realistic and compelling reasons to take their businesses online as it is transforming into a new

future of business altogether.

The client/server architecture is a widespread one. Modern web-servers, the Online Railway

Reservation, Banking Networks and many operating systems use a client server model. Most of



5/83


these systems allow for multiple clients to interact with a server at once, and hence require the

server to be safe when operating concurrently.

System to be made:

The Automated Online Railway Reservation System will service one customer at a time. A

customer will be required to login and enter a password for validation. The customer will then be

able to perform one or more actions as mentioned above. A 16 digits identification number (PIN)

will entered in regards to pay the fare of any Ticket reservation.

Requirements:

An automated Online Railway Reservation System must be able to provide the following services

to the customer:

1. A customer must be able to check the availability of seats.

2. A customer must be able to reserve the seats available with Seat/birth Details.

3. A customer must be able to check the reservation scheduled fares, Ticket Details, Seat/birth

Details and status of Confirmation.

4. A customer can cancel the reservation and the status of the available seats should be

updated in order to maintain the integrity and consistency.

5. A customer must be able to make a payment by entering a 16-digits code from any suitable

account linked to any credit card to pay the fare. Proper validation should be there.

6. The customer can check the Booked Ticket Payment Details and Ticket Confirmation.

7. A customer must be able to abort a transaction in progress by pressing the Cancel key

instead of responding to a request from the machine.

Validations and Assumption:

1. The Automated Online Railway Reservation System will verify all the actions taken. If the

customer's identification number is invalid (not of 16 digits), the customer will be required to re-



6/83


enter the number before an action to be proceed. If the customer is unable to successfully enter the

id number after three tries, the action should be canceled automatically.

2. The AORRS will display the Ticket Details with Customers Details for each successful paid

fare.

3. The AORRS will also maintain an internal log of transactions to facilitate resolving ambiguities

arising from a hardware failure in the middle of a transaction. Entries will be made in the log when

the AORRS is started up and shut down, for each message sent to the Customer (along with the

response back, if one is expected). Log entries may contain all the information, but for security will

never contain an identification number.

Architecture of the Application:

The architecture of any system refers to splitting each piece of the applications functionality into

separate components based on what they do and grouping each kind of component into a single

logical tier. Client-server software architecture is versatile and flexible in todays fast-changing ITlandscape. It is modular in structure and relies on messaging services for communication between

components. They were designed to improve flexibility, usability, scalability, and interoperability.

Software flexibility implies the ability for a program to change easily according to different users

and different system requirements.

Architecture Used Three Tier Architecture



7/83


In web applications, the client side is usually written in HTML meanwhile the application servers

are usually written in C++ or Java. By using a scripting language embedded in HTML, web servers

act as translation layers that allow for communication between the client and server layers.

Java Concurrent Programming Techniques Used

The java technologies and appropriate coding techniques should be used. First of all, the entire

application could be divided into two major sections, namely presentation and business logic parts.

All activities related to them are separated from the UI part to make the system modular, reusable

and manageable.

Utilization of inheritance, interface, and composition: - One of the major principles of the objectoriented system design is to decouple as much as possible to make the system more manageable. In

this way, the Online Railway Reservation application has been developed with the implementation

of interfaces, use of inheritance and finally with composition for runtime dynamic requirement of

the system.



8/83


Use of Composition:-Although the use of interface provides a better way for implement methods

but still it works within the static structure of the system. If an object is to be used only at run time

with variations in type and behavior of object, composition is the answer for it.

Separation of monitors thread and associated class: classes are grouped as monitors, threads and

associated classes based on the role and participation in the Online Railway Reservation system.

Most of the UI part acts as passive so they are implemented as monitors and associated classes and

the major events of the system are represented by the thread objects, such as an arrival of a

Customer request.

Concurrent Programming:In a concurrent program, several streams of operations

may execute concurrently. Each stream of operations executes as it would in a sequential

program except for the fact that streams can communicate and interfere with one another. It is

used to increase the performance, throughput, and application responsiveness. Above all it more

appropriate to represent simulations in the real world scenario.

Threads:A thread is runnable unless it executes a special operation requiring synchronization

that waits until a particular condition occurs. If more than one thread is runnable, all but one thread

may starve (make no progress because none of its operations are being executed) unless the

language makes afairness guarantee. A fairness guarantee states that the next operation in a

runnable thread eventually will execute. The Java language specification currently makes no

fairness guarantees but most Java Virtual Machines guarantee fairness. The Java programming

language relies primarily on shared variables to support communication between processes, but it

also supports an explicit signaling mechanism.

Semaphores and monitors:Semaphores: Is another data structure that provides mutual exclusion to critical sections.

Semaphores can also be used as atomic counters.

Semaphores support two operations:

wait(semaphore): decrement, block until semaphore is open



9/83


Also P (), after the Dutch word for test, or down ()

signal(semaphore): increment, allow another thread to enter

Also V () after the Dutch word for increment, or up ()

Monitors: A monitor is a programming language construct that controls access to shared data

Why is this advantage?

A monitor is a module that encapsulates

Shared data structures

Procedures that operate on the shared data structures

Synchronization between concurrent procedure invocations A monitor protects its data from unstructured access

It guarantees that threads accessing its data through

A monitor guarantees mutual exclusion

Only one thread can execute any monitor procedure at any

Time (the thread is in the monitor)

If a second thread invokes a monitor procedure when a first

Thread is already executing one, it blocks

So the monitor has to have a wait queue

If a thread within a monitorblocks, another one can enter.

Associated classes, safety and aliveness:

Apart from the monitors and threads, there are other classes which are support classes or business

logic classes which does not fall into either category. In the online railways reservation system

there are many classes under this categorization. Safety and aliveness of the system has been

implemented in the form of monitors and conditional synchronizations.



10/83


Error debugging:

Elimination of Concurrency programming errors or difficulties

When resources are shared and are accessed by concurrent threads it is clear there would be more

chances for deadlock if all four deadlock conditions prevail. Apart from deadlock, another problem

that may not hang the system but might cause serious problems is the data corruptions.

CRITICAL APPRAISAL

Computing and Concurrent System Design is a very important subject in field of Computer science

regardless of specialization in any particular field. The assignment has covered all the practical

aspects that we have learnt, with some additional requirement which really was a challenge

We had never been exposed to the concept of concurrency programming. Till now in our course

we had been working on object oriented programming language. It was very exciting for me to

study Concurrency Programming in Java for the first time. But the problem which we faced was

far complicated than the excitement.

1. I learnt how to prepare FSP, generate LTS diagram using tool LTSA.

2. Testing the model using the LTSA tool was really helpful in finding errors including safety and

aliveness.

3. Acquired the skills to implement concurrent systems in Java in a systematic way, requirement ->

Model -> Implementation. Extensive use of threads, monitors and other features helped the

developer to learn concurrent programming in practice.

4. Obtained knowledge in the areas of concurrency, deadlock, deadlock avoidance, parallel

composition of asynchronous processes, interleaving, structure diagrams, monitors and Conditional

Synchronization, Safety & Aliveness properties.

I referred to the book prescribed by my lecturer and many tutorials and online materials available

to understand the workings in concurrency and State models and programming language. The

concurrency concept leads to think the programming language in terms of real object in a

simulated. In conclusion, I really appreciate the subject and plan to further research in this field. If

I am given another project of this type, I will try to work on it by following the right steps based on

the given approach and strategy of concurrent system design
