ABSTRACT

The project entitled Multipurpose editorprovides a user to create, edit and

execute different programming languages in a single window. We can build and

compile various programs in a single environment using IDE (Integrated

Development Environment).

The programming languages can be used in this project are:

C

C++ JAVA

We can also use a database MYSQL for store the information in table format

and to do other database applications. The compilation and execution of

different programming languages is according to the extension with which that

are saved.

Previously the programming was done in separate platforms. For different

languages different platforms were required. Sometimes, extra efforts wererequired for compilation and execution of programs especially in the case of

java. The main drawbacks are listed below.

Different platforms are required for different languages.Extra efforts are required.Familiarization with each compiler is required.

The drawbacks of the existing system are listed. Almost all the drawbacks of the

existing system could be removed to a great extend.

Creation, compilation and execution of different programminglanguages in a single window.

INTRODUCTION

CHAPTER 1

INTRODUCTION

1.1ObjectivesVarious graphical password schemes have been proposed as alternatives to text-based

passwords. Research and experience have shown that text-based passwords are fraught with

both usability and security problems that make them less than desirable solutions. Psychology

studies have revealed that the human brain is better at recognizing and recalling images than

text. Graphical passwords are intended to capitalize on this human characteristic in hopes that

by reducing the memory burden on users, coupled with a larger full password space offered

by images, more secure passwords can be produced and users will not resort to unsafe

practices in order to cope.

GRAPHICAL PASSWORD AUTHENTICATION proposes a new click-based graphical

password scheme called Cued Click Points (CCP). It can be viewed as a combination of

PassPoints, Pass faces and Story. A password consists of one click-point per image for a

sequence of images. The next image displayed is based on the previous click-point so users

receive immediate implicit feedback as to whether they are on the correct path when logging

in. CCP offers both improved usability and security. Users could quickly create and re-enter

their passwords. Another feature of ccp is the immediate implicit feedback telling the correct

user whether their latest click-point was correctly entered.

SYSTEM ANALYSIS

2.1 Existing System

Previously the programming was done in separate platforms. For different

languages different platforms were required. Sometimes, extra efforts were required for

compilation and execution of programs especially in the case of java. The main drawbacks

are listed below.

Different platforms are required for different languages. Extra efforts are required.Familiarization with each compiler is required.

2.2 Proposed System

The drawbacks of the existing system are listed. Almost all the drawbacks of the

existing system could be removed to a great extend.

Creation, compilation and execution of different programming languagesin a single window.

Easy to work Execution of programs in less time Less complexity

2.3 Feasibility Study

Feasibility study is the evaluation of system regarding its workability, impact on the

organization, ability to meet the user needs and effective use of resources. It is both necessary

and prudent to evaluate the feasibility of a project at the earliest possible time.Months or

years of effort, thousands and millions of dollars, and untold professional embarrassment can

be averted if an ill-conceived system is recognized early in the definition of phase. Feasibility

and risk analysis are related in many ways. If project risk is great, the feasibility of producing

quality software is reduced.

Three key factors are to be considered during the feasibility study.

Economical Feasibility Operational Feasibility Technical Feasibility

2.3.1 Economical Feasibility


12/25

Economic Feasibility is the most important and frequently used method for evaluating

the effectiveness of the proposed system. It is very essential because the main goal of the

proposed system is to have economically better result along with increased efficiency.

Economical feasibility deals with the analysis of cost against benefits i whether the benefits

to be enjoyed due to the new system are worthy, when compared to the costs to be spent on

the system. Economic justification is generally the bottom-line consideration for most

system, long-term corporate income strategies, impact on other profit centers or products,

cost of the resources needed for development, and potential market growth. Especially in the

present scenario, where the objective is towards compatibility, reduced cost is weighed

against the ultimate income or benefit derived from the developed system.

The expenditures must be justified. Thus the developed system as well within the

budget and this has been achieved because most of the technologies used are freely available.

Only the customized products had to be purchased.

2.3.2 Operational Feasibility

The study is made to know whether the proposed system is operationally feasible

or not. When the highlight is made to this project, it will work very effective compared to the

existing system. An estimate should be made to determine how much effort and care will go

into the developing of the system including the training to be given to the user. Usually,

people are reluctant to changes that come in their progression.

In operational Feasibility there are two sessions one is practice and another is

login session. In practice session, It targetsa string with at least ten characters will be used

according to in the enrollment; ten samples were collected from each user.

2.3.3 Technical Feasibility

Technical feasibility is the need of hardware and software, which are needed to

implement the proposed system in the organization. The system analyst has to check the

technical feasibility of the proposed system. Taking account of the hardware, which is used

for the system development, data storage, processing and output, makes the technical

feasibility assessment. Technical requirements are to be fulfilled to make the proposed

system work. The main consideration is to be given to the study of available resources of the

organization where the software is to be implemented. The system analyst evaluates the

technical merits of the system giving emphasis on the performance, reliability,

maintainability and productivity.By taking the above consideration before developing the


13/25

proposed system, the resource availability of the organization has been studied. The

organization has immense computer facilities equipped with sophisticated machines and

software.

SOFTWARE DESCRIPTION

CHAPTER 4


16/25

SOFTWARE DESCRIPTION

4.1 Front End

LANGUAGE

The language used in this project is JAVA/J2EE.

JAVA:

Java is the first programming language designed from ground up with network programming

in mind. The core API for Java includes classes and interfaces that provide uniform access to

a diverse set of network protocols. As the Internet and network

Programming has evolved java has maintained its cadence. New APIs and toolkit have

expanded the available options for the java network programmer.

Java is both a programming language and an environment for executing programs written in

java language. Unlike traditional compilers, which convert source code into machine level

instructions, the java compiler translates java source code into instructions that are interpreted

by the runtime Java Virtual Machine. So unlike language like C and C++, Java is an

interpreted language

Java Environment:

The java environment is composed of several separate entities.

Java Language:

This is a language that follows object-oriented concept used to create executable contents

such as applications and applets. But Java is not pure object oriented language, it does not

support multiple inheritance & Operator overloading.

Java Runtime Environment:

The runtime environment used to execute the code. It is made up of the java language and

java virtual machine. It is portable and it is platform neutral.

Java tools:

It is used by the developers to create java code. They include java compiler, java interpreter,

classes, libraries and applet viewer.

Java Application:

Applications are programs written in java to carry out certain tasks on stand alone local

computer. Execution of a stand-alone program involves two steps.


17/25

1. Compiling the source code in to byte code using javac.

2. Executing byte code program using java interpreter

Java Applets:

Java applets are pieces of java code that are embedded in HTML document using the applettag. When the browser encounters such code it automatically download it and execute it.

Java Virtual Machine:

It is a specification to which java codes must be written. All java code is to be compiled in

this nonexistent virtual machine. Writing the code that compiles in JVM ensures platform

independence.

Advantages of Java

Java is Robust:

Robust programs are those reliable programs that are unlikely to fail even under the most

unlikely conditions. Many languages like C do not have this feature because they are relaxed

in terms of type checking in terms of programming errors. Java is strict about type declaration

and does not allow automatic typecasting. Also it uses a pointer model that does not

overwrite memory or corrupt data.

Java is secure:

Java allows creation of virus-free, tamper free systems to be created. It ensures security in the

following ways.

interpreter verifies all byte codes before executing.

Because Java was written to support distributed applications over the computer networks, it

can be used with a variety of CPU and operating system architectures. To achieve this goal a

compiler was created that produces architecture-neutral object files from Java code.

Java is Portable:

Java byte code will be executed on any computer that has Java Runtime Environment. The

portability is achieved in the following ways.

explicitly specified.


18/25

e

environment is available.

Java is small:

Because java was designed to run on small computers, java system is relatively small for a

programming language. It can run efficiently on PCs with 4MB RAM or more. The java

interpreter takes up only a few hundred-kilo bytes.

Java is garbage collected:

Java programs dont have to worry about memory management. The java system has a built

in program called the garbage collector, which scans the memory and automatically frees the

memory chunks that are not in use.

Java is dynamic:

Fundamentally distributed computer environments must be dynamic. Java is capable of

dynamic linking new libraries, methods and instance variables as it goes without breaking

and without concern.

Java Swing:

The swing classes eliminate Javas biggest weakness: Its relatively primitive user interface

toolkit. Swing provides many new components and containers that allow us to build

sophisticated user interfaces, far beyond what was possible with AWT. The old components

have been greatly improved, and there are manynew components, like trees, tables, and even

text editors. It also adds several completely new features to Javas user interface capabilities:

drag-and-drop, undo, and the ability to develop our own Look and Feel, or the ability to

choose between several standard looks. The swing components are all lightweight, and

therefore provide more uniform behavior across platforms, making it easier to test our

software.

Reason for Using Java:

It is required to explore systems running different operating system. In order to do so, there

should be some way to connect to bridge those operating systems so that all the differences

between them are solved and the functionalities are achieved. Also the functions performed in

one system should be able to transfer to another and the result should be able to reflect there


19/25

properly. Java serves as a bridge between these Operating systems. Also java is widely

considered to be the best in developing network applications.

The communication happens between Java Virtual Machines running on the systems. When

the client wants to perform the functionalities in another system and see the result, a method

in the remote system is invoked from the client. The corresponding method in the remote

system performs the job and sends the results to the client that is reflected in its interface.

NETBEANS IDE

The Net Beans Platform allows applications to be developed from a set of modular software

components called modules. A module is a Java archive file that contains Java classes written

to interact with the Net Beans Open APIs and a manifest file that identifies it as a module.

4.2 Back End

SQL SEVER

SQL Server 2008 delivers several breakthrough capabilities that will enables the

organization to scale database operations with confidence, improve IT and developer

efficiency, and enable highly scalable and well managed Business Intelligence on a self-

service basis for users.

SQL Server 2008 is a powerful and reliable data management system that delivers a rich set

of features, data protection, and performance for embedded application clients, light Web

applications, and local data stores.

SQL Server 2008 provides s the enterprise data management platform your organization

needs to adopt quickly in a fast changing environment. With the lowest implementation and

maintenance cost in the industry. SQL Server 2008 is a fully enterprise class data base

product, providing core support for Extensible Markup Language and internet queries.

SQL (Structured Query Language)

SQL is used by for all interaction with the database. SQL*Plus is based on SQL,

but it has some oracle specific features that can be used for writing reports and controlling the

way screen and paper output is formatted the ANSI (American National Standard Institute for

standards for Instructions for Information) defines the standards to the SQL query.


20/25

The SQL is broadly classified into four categories.

1.Data Definition Language (DDL).

2.Data Manipulation Language (DML).

3.Data Transaction Language (DTL).

4.Data Control Language (DCL).

Definition language

Data Definition Language in the SQL construct used to define data in the database.When you

define the data, the entries are made into Oracles data dictionary. DDL allows the

programmer to create, modify and remove a database. The DDL commands are Create, Alter

and Drop.

Data Manipulation Language

Data Manipulation Language is the SQL construct used to define data in the database.The

DML allows the programmer to insert, update, delete, and select data in the database. The

DML statements are SQL commands that allow users to manipulate the data in the database.

Data Transaction Language

Data Transaction Language is the AQL construct used the transactions. Common statements

are commit and rollback.

Data Control Language

Data Control Language is the SQL construct used to control the behavior of the data.

Common statements are grant and revoke

CHAPTER 5

PROJECT DESCRIPTION

5.1 Problem Definition

The project entitled Multipurpose editor provides a user to create, edit and execute

different programming languages in a single window. We can build and compile various

programs in a single environment using IDE (Integrated Development Environment).

5.2 Overview Of The Project

5.3 Module Description

The different modules contained in this project are

Program creation

Program compilation Program execution Database listing

In the program creation module we create an editor window. This module includes

cut, copy, paste and format. Here we can write a new program or open already existing

program and further operations are done.

In the program compilation module we convert our source code program to themachine readable format. Through the compilation process we can identify the syntactic

errors and also we can rectify the errors.

The third module is program execution module. After correcting all the errors in the

program we can execute the program within a click of mouse. The output is displayed in the

output window.


23/25

The last module is database listing. In this module we can view the database. The

query generation and execution are done in this module. When the query executed in the

editor it is activated in the database engine.

5.4System Flow DiagramA data flow diagram is graphical tool used to describe and analyze movement of data

through a system. These are the central tool and the basis from which the other components

are developed. The transformation of data from input to output, through processed, may be

described logically and independently of physical components associated with the system.

These are known as the logical data flow diagrams.

The physical data flow diagrams show the actual implements and movement of data

between people, departments and workstations. A full description of a system actually

consists of a set of data flow diagrams. Using two familiar notations Yourdon, Gane and

Sarson notation develops the data flow diagrams. Each component in a DFD is labeled with a

descriptive name. Process is further identified with a number that will be used for

identification purpose. The development of DFDs is done in several levels. Each process inlower level diagrams can be broken down into a more detailed DFD in the next level. The

lop-level diagram is often called context diagram. It consists a single process bit, which plays

vital role in studying the current system. The process in the context level diagram is

exploded into other process at the first level DFD.The idea behind the explosion of a process

into more process is that understanding at one level of detail is exploded into greater detail at

the next level. This is done until further explosion is necessary and an adequate amount of

detail is described for analyst to understand the process.Larry Constantine first developed the

DFD as a way of expressing system requirements in a graphical from, this lead to the

modular design.

A DFD is also known as a bubble Chart has the purpose of clarifying system

requirements and identifying major transformations that will become programs in system

design. So it is the starting point of the design to the lowest level of detail. A DFD consists

of a series of bubbles joined by data flows in the system.

DFD SYMBOLS:


24/25

In the DFD, there are four symbols

1. A square defines a source(originator) or destination of system data

2. An arrow identifies data flow. It is the pipeline through which the information flows

A circle or a bubble represents a process that transforms incoming data flow into outgoing

data flows.

3. An open rectangle is a data store, data at rest or a temporary repository of data

CONSTRUCTING A DFD:

Several rules of thumb are used in drawing DFDs:

1. Process should be named and numbered for an easy reference. Each name should berepresentative of the process.

2. The direction of flow is from top to bottom and from left to right. Data Traditionally flowfrom source to the destination although they may flow back to the source. One way to

indicate this is to draw long flow line back to a source. An alternative way is to repeat the

source symbol as a destination. Since it is used more than once in the DFD it is marked

with a short diagonal.

3. When a process is exploded into lower level details, they are numbered.4. The names of data stores and destinations are written in capital letters. Process and

dataflow names have the first letter of each work capitalized


25/25

A DFD typically shows the minimum contents of data store. Each data store should

contain all the data elements that flow in and out.Questionnaires should contain all the

data elements that flow in and out. Missing interfaces redundancies and like is then

accounted for often through interviews.

5.5 DATABASE DESIGN

To design an application it is necessary to design a database file. These files are called tables.

After designing the output and input, tables must be organized according to the storage needs of the

back end used.

Normalization procedure is used to avoid duplication of data and to produce feasibility

necessary to support different functional requirements. To achieve this system is passed through

various normal forms such as first normal form, second normal form and third normal form.
