CONFERENCE MANAGEMENT SYSTEM PROJECT SOURCE CODE

 INTRODUCTION & OBJECTIVE

‘Organizational Conference’ is a web application used to conduct conference among employees of multiple branches of same Organization.

       It provides facility for recruitment of employees required in the Organization.

 PURPOSE OF THE PROJECT - ONLINE CONFERENCE MANAGEMENT SYSTEM PROJECT

To conduct discussions among employees who are working under a same company but under

 Different branches. They can do online discussions as well as offline discussions and to get

 Reports on discussions happened on required topic

  EXISTING SYSTEM & DISADVANTAGES

These days lots of organizations are arranging conferences to their employees manually, Which takes them to stop their works and commit their time in meeting room to discuss their problems and new assignments .So, to avoid this problem we are going to introduce an online Conference to provide communication between employees

 PROPOSED SYSTEM & ADVANTAGES

This web application is designed and developed to conduct conference among the employees to solve their problems arises in the working time or to take decisions regarding facing new situations etc., it also provides a facility to recruit employees when ever the requirement arises in the Organization

  

SYSTEM ANALYSIS

FEASIBILITY STUDY - ONLINE CONFERENCE MANAGEMENT SYSTEM PROJECT

Preliminary investigation examines project feasibility, the likelihood the system will be useful to the organization. The main objective of the feasibility study is to test the Technical, Operational and Economical feasibility for adding new modules and debugging old running system. All systems are feasible if they are given unlimited resources and infinite time. There are aspects in the feasibility study portion of the preliminary investigation:

• Technical Feasibility
• Operation Feasibility

Economical Feasibility

 TECHNICAL FEASIBILITY

The technical issue usually raised during the feasibility stage of the investigation includes the following:

• Does the necessary technology exist to do what is suggested?
• Do the proposed equipments have the technical capacity to hold the data required to use the new system?
• Will the proposed system provide adequate response to inquiries, regardless of the number or location of users?
• Can the system be upgraded if developed?

Are there technical guarantees of accuracy, reliability, ease of access and data security?

 OPERATIONAL FEASIBILITY

OPERATIONAL FEASIBILITY

User-friendly

Customer will use the forms for their various transactions i.e. for adding new routes, viewing the routes details. Also the Customer wants the reports to view the various transactions based on the constraints. Theses forms and reports are generated as user-friendly to the Client.

Reliability

The package wills pick-up current transactions on line. Regarding the old transactions, User will enter them in to the system.

Security

The web server and database server should be protected from hacking, virus etc

Portability

The application will be developed using standard open source software (Except Oracle) like Java, tomcat web server, Internet Explorer Browser etc these software will work both on Windows and Linux o/s.  Hence portability problems will not arise.

Availability

 This software will be available always.

Maintainability

     

The system called the ewheelz uses the 2-tier architecture. The 1st tier is the GUI, which is said to be front-end and the 2nd tier is the database, which uses My-Sql, which is the back-end.  

The front-end can be run on different systems (clients). The database will be running at the server. Users access these forms by using the user-ids and the passwords.

 ECONOMIC FEASIBILITY

The computerized system takes care of the present existing system’s data flow and procedures completely and should generate all the reports of the manual system besides a host of other management reports.

It should be built as a web based application with separate web server and database server. This is required as the activities are spread through out the organization customer wants a centralized database. Further some of the linked transactions take place in different locations. 

     Open source software like TOMCAT, JAVA, Mysql and Linux is used to minimize the cost for   the Customer.

EXISTING SYSTEM & DISADVANTAGES

These days lots of organizations are arranging conferences to their employees manually, Which takes them to stop their works and commit their time in meeting room to discuss their problems and new assignments .So, to avoid this problem we are going to introduce an online Conference to provide communication between employees

PROPOSED SYSTEM & ADVANTAGES - ONLINE CONFERENCE MANAGEMENT SYSTEM PROJECT

This web application is designed and developed to conduct conference among the employees to solve their problems arises in the working time or to take decisions regarding facing new situations etc., it also provides a facility to recruit employees when ever the requirement arises in the Organization

  

SYSTEM REQUIREMENT SPECIFICATION

OPERATING ENVIRONMENT - ONLINE CONFERENCE MANAGEMENT SYSTEM PROJECT

Performance is measured in terms of the output provided by the application. Requirement specification plays an important part in the analysis of a system. Only when the requirement specifications are properly given, it is possible to design a system, which will fit into required environment. It rests largely with the users of the existing system to give the requirement specifications because they are the people who finally use the system.  This is because the requirements have to be known during the initial stages so that the system can be designed according to those requirements.  It is very difficult to change the system once it has been designed and on the other hand designing a system, which does not cater to the requirements of the user, is of no use.

The requirement specification for any system can be broadly stated as given below:       

·         The system should be able to interface with the existing system

·         The system should be accurate

·         The system should be better than the existing system

The existing system is completely dependent on the user to perform all the duties.

To provide flexibility to the users, the interfaces have been developed that are accessible through a browser. The GUI’S at the top level have been categorized as

1. Administrative user interface
2. The operational or generic user interface

The ‘administrative user interface’ concentrates on the consistent information that is practically, part of the organizational activities and which needs proper authentication for the data collection. These interfaces help the administrators with all the transactional states like Data insertion, Data deletion and Date updation along with the extensive data search capabilities.

The ‘operational or generic user interface’ helps the end users of the system in transactions through the existing data and required services. The operational user interface also helps the ordinary users in managing their own information in a customized manner as per the included flexibilities

 INPUT & OUTPUT REPRESENTATION

Input design is a part of overall system design.  The main objective during the input design is as given below:

·         To produce a cost-effective method of input.

·         To achieve the highest possible level of accuracy.

·         To ensure that the input is acceptable and understood by the user.

INPUT STAGES:

The main input stages can be listed as below:

·       Data recording

·       Data transcription

·       Data conversion

·       Data verification

·       Data control

·       Data transmission

·       Data validation

·       Data correction

INPUT TYPES:

It is necessary to determine the various types of inputs.  Inputs can be categorized as follows:

·       External inputs, which are prime inputs for the system.

·       Internal inputs, which are user communications with the system.

·       Operational, which are computer department’s communications to the system?

·       Interactive, which are inputs entered during a dialogue.

INPUT MEDIA:

At this stage choice has to be made about the input media.  To conclude about the input media consideration has to be given to;    

·       Type of input

·       Flexibility of format

·       Speed

·       Accuracy

·       Verification methods

·       Rejection rates

·       Ease of correction

·       Storage and handling requirements

·       Security

·       Easy to use

·       Portability

Keeping in view the above description of the input types and input media, it can be said that most of the inputs are of the form of internal and interactive.  As

Input data is to be the directly keyed in by the user, the keyboard can be considered to be the most suitable input device.

OUTPUT DESIGN:

in general are:

• External Outputs whose destination is outside the organization.
• Internal Outputs whose destination is with in organization and they are the User’s main interface with the computer. Outputs from computer systems are required primarily to communicate the results of processing to users. They are also used to provide a permanent copy of the results for later consultation. The various types of outputs
• Operational outputs whose use is purely with in the computer department.
• Interface outputs, which involve the user in communicating directly with the system.

 INTRODUCTION TO JAVA

About Java:

Initially the language was called as “oak” but it was renamed as “java” in 1995.The primary motivation of this language was the need for a platform-independent(i.e. architecture neutral)language that could be used to create software to be embedded in various consumer electronic devices.

     Java is a programmer’s language

     Java is cohesive and consistent

     Except for those constraint imposed by the Internet environment. Java gives the programmer, full control

Finally Java is to Internet Programming where c was to System Programming.

Importance of Java to the Internet

Java has had a profound effect on the Internet. This is because; java expands the Universe of objects that can move about freely in Cyberspace. In a network, two categories of objects are transmitted between the server and the personal computer. They are passive information and Dynamic active programs. in the areas of Security and probability. But Java addresses these concerns and by doing so, has opened the door to an exciting new form of program called the Applet.

Applications and applets. An application is a program that runs on our Computer under the operating system of that computer. It is more or less like one creating using C or C++ .Java’s ability to create Applets makes it important. An Applet I san application, designed to be transmitted over the Internet and executed by a Java-compatible web browser. An applet I actually a tiny Java program, dynamically downloaded across the network, just like an image. But the difference is, it is an intelligent program, not just a media file. It can be react to the user input and dynamically change. 

 Servlets/JSP

INTRODUCTION

A Servlet Is a generic server extension. a Java class that can be loaded

Dynamically to expand the functionality of a server.Servlets are commonly used with web servers. Where they can take the place CGI scripts.

A servlet is similar to proprietary server extension, except that it runs inside a Java Virtual Machine (JVM) on the server, so it is safe and portable

Servlets operate solely within the domain of the server.

Unlike CGI and Fast CGI, which use multiple processes to handle separate program or separate requests, separate threads within web server process handle all servlets. This means that servlets are all efficient and scalable.

Servlets are portable; both across operating systems and  also across web servers. Java Servlets offer the best possible platform for web application development.

Servlets are used as replacement for  CGI scripts on a web server, they can extend any sort of server such as a mail server that allows servelts t extend its functionality perhaps by performing a virus scan on all attached documents or handling mail filtering tasks.

Servlets provide a Java-based solution used to address the problems currently associated with doing server-side programming including inextensible scripting solutions platform-specific API’s and incomplete interface.

Servlets are objects that conform to a specific interface that can be plugged into a Java-based server.Servlets are to the server-side what applets are to the server-side what applets are to the client-side-object byte codes that can be dynamically loaded off the net. They differ form applets in than they are faceless objects(with out graphics or a GUI component).They serve as platform independent, dynamically loadable,plugable helper byte code objects on the server side that can be used to dynamically extend server-side functionality.

      For example an HTTP servlet can be used to generate dynamic HTML content when you use servlets to do dynamic content you get the following advantages:

     They’re faster and cleaner then CGI scripts

     They use a standard API( the servlet API)

     They provide all the advantages of Java (run on a variety  of servers without needing  to be rewritten)

A t t r a c t i v e n e s s o f S e r v l e t s:

      They are many features of servlets that make them easy and attractive to tuse these include:

     Easily configure using the  GUI-based Admin tool]

     Can be Loaded and Invoked from a local disk or remotely across the network.

     Can be linked together or chained, so that on servlet can call another servlet, or several servlets in sequence.

     Can be called dynamically from with in HTML, pages using server-side include-tags.

     Are secure-even when downloading across the network, the servlet security model and servlet and box protect your system from unfriendly behavior.,

Advantages of the servlet API

      One of the great advantages of the servlet API is protocol independent. It assumes nothing about:

     The protocol being used to transmit on the net

     How it is loaded

     The server environment it will be running in

     These quantities are important, because it allows the Servlet API to be embedded in many different kinds of servers.There are other advantages to the servelt API as well These include:

     It’s extensible-you can inherit all your functionality from the base classes made available to you

     It’s simple small, and easy to use.

Features of Servlets:

     Servlets are persistent.Servlet are loaded only by the web server and can maintain services between requests.

     Servlets are fast. Since servlets only need to be l\loaded once, they offer much better performance over their CGI counterparts.

     Servlets are platform independent.

     Servlets are extensible Java is a robust, object-oriented programming language, which easily can be extended to suit your  needs.

     Servlets are secure

     Servlets are used with a variety of client.

Servlets are classes and interfaces from tow packages,javax .servlet and javax.servlet.http.The java.servlet package contains classes t support generic, protocol-independent servlets.The classes in the javax.servelt.http package To and HTTP specific functionality extend these classes

Every servlet must implement the javax.servelt interface.Most servlets implement it by extending one of two classes.javax.servlet.GenericServlet or javax.servlet.http.HttpServlet.A protocol-independent servlet should subclass Generic-Servlet.while an Http servlet should subclass HttpServlet, which is itself a subclass of Generic-servlet with added HTTP-specific functionality.

Unlike a java program, a servlet does not have a main() method,Instead the server in the process of handling requests invoke certain methods of a servlet.Each time the server dispatches a request to a servlet, it invokes the servelts Service() method,

A generic servlet should override its service() method to handle requests as appropriate for the servlet.The service() accepts two parameters a request object and a response object .The request object tells the servlet about the request, while the response object is used to return a response

InContrast.anHttp servlet usually does not override the service() method.Instead it overrides doGet() to handle GET requests and doPost() to handle Post requests. An Http servlet can override either or both of these modules the  service() method of HttpServlet handles the setup and dispatching to all the doXXX() methods.which iswhy it usually should not  be overridden

The remainders in the javax.servlet and javax.servlet.http.package are largely support classes .The ServletRequest and ServletResponse classes in javax.servlet provide access to generic server requests and responses while HttpServletRequest and HttpServletResponse classes in javax.servlet provide access to generic server requests and responses while HttpServletRequest and HttpServletResponse in javax.servlet.http provide access a HTTP requests and responses . The javax.servlet.http provide contains an HttpSession class that provides built-in session tracking functionality and Cookie class that allows quickly setup and processing HttpCookies.

Loading Servlets:

Servlets can be loaded from their places. From a directory that is on the CLASSPATH. The CLASSPATH of the JavaWebServer includes service root/classes/, which is where the system classes reside

From the

Loading Remote Servlets

Remote servlets can be loaded by:

     Configuring the admin Tool to setup automatic loading of remote servlets.

     Selectiong up server side include tags in .html files

     Defining a filter chain Configuration

JDBC

What is JDBC?

any relational database. One can write a single program using the JDBC API,and the JDBC is a Java Api for executing SQL,Statements(As a point of interest JDBC is trademarked name and is not an acronym; nevertheless,Jdbc is often thought of as standing for Java Database Connectivity. It consists of a set of classes and interfaces written in the Java Programming language.JDBC provides a standard API for tool/database developers and makes it possible to write database applications using a pure Java API

Using JDBC, it is easy to send SQL statements to virtually program will be able to send SQL .statements to the appropriate database. The Combination of Java and JDBC lets a programmer writes it once and run it anywhere.

What Does JDBC Do?

      Simply put,JDBC makes it possible to do three things

o      Establish a connection with a database

o      Send SQL statements

o      Process the results

o      JDBC Driver Types

o      The JDBC drivers that we are aware of this time fit into one of four categories

o      JDBC-ODBC Bridge plus ODBC driver

o      Native-API party-java driver

o      JDBC-Net pure java driver

o      Native-protocol pure Java driver

An individual database system is accessed via a specific JDBC driver that implements the java.sql.Driver interface. Drivers exist for nearly all-popular RDBMS systems, through few are available for free. Sun bundles a free JDBC-ODBC bridge driver with the JDK to allow access to a standard ODBC,data sources, such as a Microsoft Access database, Sun advises against using the bridge driver for anything other than development and very limited development.

       JDBC drivers are available for most database platforms, from a number of vendors and in a number of different flavours. There are four driver categories

Type 01-JDBC-ODBC Bridge Driver

     

      Type 01 drivers use a bridge technology to connect a java client to an ODBC database service. Sun’s JDBC-ODBC bridge is the most common type 01 driver. These drivers implemented using native code.

Type 02-Native-API party-java Driver

      Type 02 drivers wrap a thin layer of java around database-specific native code libraries for Oracle databases, the native code libraries might be based on the OCI(Oracle call Interface) libraries, which were originally designed for c/c++ programmers, Because type-02 drivers are implemented using native code. in some cases they have better performance than their all-java counter parts. They add an element of risk, however, because a defect in a driver’s native code section can crash the entire server

Type 03-Net-Protocol All-Java Driver

Type 03 drivers communicate via a generic network protocol to a piece of custom middleware. The middleware component might use any type of driver to provide the actual database access. These drivers are all java, which makes them useful for applet deployment and safe for servlet deployment

Type-04-native-protocol All-java Driver

Type o4 drivers are the most direct of the lot. Written entirely in java, Type 04 drivers understand database-specific networking. protocols and can access the database directly without any additional software

Oracle (Access)

Oracle is a relational database management system, which organizes data in the form of tables. Oracle is one of many database servers based on RDBMS model, which manages a seer of data that attends three specific things-data structures, data integrity and data manipulation.

With oracle cooperative server technology we can realize the benefits of open, relational systems for all the applications. Oracle makes efficient use of all systems resources, on all hardware architecture; to deliver unmatched performance, price performance and scalability. Any DBMS to be called as RDBMS has to satisfy Dr.E.F.Codd’s rules.

 JAVA SCRIPT -ONLINE CONFERENCE MANAGEMENT SYSTEM PROJECT

The Java Script Language

JavaScript is a compact, object-based scripting language for developing client and server internet applications. Netscape Navigator 2.0 interprets JavaScript statements embedded directly in an HTML page. and Livewire enables you to create server-based applications similar to common gateway interface(cgi) programs.

In a client application for Navigator, JavaScript statements embedded in an HTML Page can recognize and respond to user events such as mouse clicks form

Input, and page navigation.

For example, you can write a JavaScript function to verify that users enter valid information into a form requesting a telephone number or zip code . Without any network transmission, an Html page with embedded Java Script can interpret the entered text and alert the user with a message dialog if the input is invalid or you can use JavaScript to perform an action (such as play an audio file, execute an applet, or communicate with a plug-in) in response to the user opening or exiting a page.

   HTML - ONLINE CONFERENCE MANAGEMENT SYSTEM PROJECT

   Hypertext Markup Language (HTML), the languages of the world wide web(WWW), allows users to produces web pages that included text, graphics and pointer to other web pages (Hyperlinks).

HTML is not a programming language but it is an application of ISO Standard 8879,SGML(Standard Generalized Markup Language),but

Specialized to hypertext and adapted to the Web. The idea behind Hypertext one point to another point. We can navigate through the information based on out interest and preference. A markup language is simply a series of items enclosed within the elements should be displayed.

Hyperlinks are underlined or emphasized works that load to other documents or some portions of the same document.

Html can be used to display any type of document on the host computer, which can be geographically at a different location. It is a versatile language and can be used on any platform or desktop

HTML provides tags(special codes) to make the document look attractive.

HTML provides are not case-sensitive. Using graphics,fonts,different sizes, color, etc.. can enhance the presentation of the document. Anything

That is not a tag is part of the document it self. 

SYSTEM DESIGN - ONLINE CONFERENCE MANAGEMENT SYSTEM PROJECT

Introduction: Systems design is the process or art of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. One could see it as the application of systems theory to product development. There is some overlap and synergy with the disciplines of systems analysis, systems architecture and systems engineering.

Architecture flow:

Below architecture diagram represents mainly flow of requests from users to database through servers. In this scenario overall system is designed in three tires separately using three layers called presentation layer, business logic layer and data link layer. This project was developed using 3-tire architecture.

URL Pattern:

  

URL pattern represents how the requests are flowing through one layer to another layer and how the responses are getting by other layers to presentation layer through server in architecture diagram.

SYSTEM TESTING

  

INTRODUCTION TO TESTING

Introduction to Testing:

Testing is a process, which reveals errors in the   program.  It is the major quality measure employed during software development. During software development.  During testing, the program is executed with a set of test cases and the output of the program for the test cases is evaluated to determine if the program is performing as it is expected to perform.

TESTING IN STRATEGIES - ONLINE CONFERENCE MANAGEMENT SYSTEM PROJECT

     In order to make sure that the system does not have errors, the different levels of testing strategies that are applied at differing phases of software development are:

Unit Testing:

Unit Testing is done on individual modules as they are completed and become executable. It is confined only to the designer's requirements.

  Each module can be tested using the following two Strategies:

Black Box Testing:

In this strategy some test cases are generated as input conditions that fully execute all functional requirements for the program. This testing has   been uses to find errors in the following categories:

      Incorrect or missing functions

      Interface errors

      Errors in data structure or external database  access

      Performance errors     

      Initialization and termination errors.

In this testing only the output is checked for correctness.

The logical flow of the data is not checked.

White Box testing:

In this the test cases are generated on the logic of each module by drawing flow graphs of that module and logical decisions are tested on all the cases. It has been uses to generate the test cases in the following cases:

ü  Guarantee that all independent paths have been Executed.                                                                             

ü  Execute all logical decisions on their true and false Sides.   

ü  Execute all loops at their boundaries and within  their operational  bounds

ü  Execute internal data structures to ensure their validity.

Integrating Testing:

Integration testing ensures that software and subsystems work together a whole.  It tests the interface of all the modules to make sure that the modules behave properly   when integrated together.

System Testing:

      Involves in-house testing of the entire system before delivery to the user.  It's aim is to satisfy the user the system meets all requirements of the client's specifications.

Acceptance Testing:

     It is a pre-delivery testing in which entire system is tested at client's site on real world data to find errors.

 

Test Approach:

Testing can be done in two ways:

 Bottom up approach

Top down approach

Bottom up Approach:        

Testing can be performed starting from smallest and lowest level modules and proceeding one at a time. For each module in bottom up testing a short program executes the module and provides the needed data so that the module is asked to perform the way it will when embedded with in the larger system. When bottom level modules are tested attention turns to those on the next level that use the lower level ones they are tested individually and then linked with the previously examined lower level modules.

Top down approach:         

This type of testing starts from upper level modules. Since the detailed activities usually performed in the lower level routines are not provided stubs are written. A stub is a module shell called by upper level module and that when reached properly will return a message to the calling module indicating that proper interaction occurred. No attempt is made to verify the correctness of the lower level module.

CONCLUSION - ONLINE CONFERENCE MANAGEMENT SYSTEM PROJECT

The efficiency of any system designed to suit an organization depends cooperation during the implementation stage and also flexibility of the system to adopt itself to the organization. Smart Warehousing System has been developed to overcome the problems with existing manual system which causes lot of problems in tracking the business activities with different people.

As evidence of the success of this system, all the data regarding users at different levels are stored at server side through which the authorized can take decisions in time, and all the transactions will be recorded in a well refined manner. The Smart Warehousing System will be best suited to any organization, which has sub location at different places.

Data Integrity is maintained by well-defined security in the database, so the reports coming out are live and accurate. In Total, productivity, quality, safety and user satisfaction are improved greatly in the organization.
