The Intranet mail server Project in Java is communication software that helps the users of an Intranet to communicate with electronic mails. The mail service in the Internet is the most useful facility that enables the users of the Internet to send mails to any one who can be anywhere in the world. There is some free mail service providers such as HOTMAIL, YAHOO etc in the Internet. An user can have his account in any server.

Now it is necessary to an organization to establish a communication path over its Intranet to facilitate electronic mail service. Also, the Intranet Mail Server (IMS) system provides the facility of mail service locally. 

Since the system is a mail service. The system has to follow the Internet standards. In technical point of view, there are two modules that are the Client module and the Server module. There are two protocols that have to be implemented for developing an mail software that are 

1. POST OFFICE PROTOCOL 3 (POP 3) and
2. SIMPLE MAIL TRANSFER PROTOCOL (SMTP). 

These protocols are nothing but set of commands. In IMS, both the server and the client used these protocols i.e. the commands that are defined in these protocols to make communication between themselves. The two protocols have to be implemented both in the server module and the client module. 

The following figure shows the place where POP 3 and SMTP fit into the TCP/IP protocol suite.

Mail Server Project Sub Systems:

 The system is designed as Internet based application. The whole system is divided into following sub – system: 

1. Server

User Agent

Mail Transfer Agent

2. Client

User Agent

Mail Transfer Agent

Chat room project is a java based application which works on socket programming. This project has features to create multiple chat rooms and invite friends to chat rooms and perform chat operation.

PROBLEM SPECIFICATION

INTRODUCTION

Every man made entity is first a concept in someone’s mind.  Computing systems like other products of technology are developed in response to perceived needs.  Sources of software product ideas include externally generated customer requirements, internal organizational requirements, marketing plans and organizational mission plans.    Most software development organizations are very selective in deciding which products to develop; not all targets of opportunity are exploited.  The decision to proceed is usually based on the outcome of a feasibility study. 

The first step in planning a software project is to prepare in the customers terminology, a concise statement of the problem to be solved and the constraints that exist for its solution.  The definitive problem statement should include a description of the present situation and the goals to be achieved by the new system. 

Problem definition requires a thorough understanding of the problem domain and the problem environment.  Techniques for gaining this knowledge include customer interview, observation of problem tasks and actual performance of the tasks by the planner.  The planner must be highly skilled in the techniques of the problem definition because different customer representatives will have different viewpoints, biases and prejudices that will influence their perception of the problem area.  In addition, customer representatives may not be familiar with the capabilities that a computer can offer in their situation, and customer representative are seldom able to formulate their problems in a manner that yield to logical, algorithmic analysis.

LIMITATIONS OF EXISTING SYSTEM 

• Existing chat application allow user to chat in a public domain only. 

• Certain chat applications permit the user to create rooms, which are private. 

• Only one-to-one communication is permitted in the private room.  Private room does not send and receive messages between more that two clients. 

• Users cannot create groups among themselves. 

• E – mail permits users to create groups but is one-way communication system. 

•  Pre determined groups and rooms created by existing chat software too does not consider the permission of other members before permitting members into that particular group.
  

This Multi Room Chat Project in Java involves in creating a separate rooms while chatting and inviting only your friends for that room.  Though you are part of any other private or public chat, this project allows you to send messages only to your group members by selecting them before sending messages.

Multi Room Chat Project Description:

            It is often said that early planning is impossible because precise information concerning project goals, customer needs and product constraints is not available at the beginning of a software project, but a major purpose of the planning phase is to clarify goals, needs and constraints.  The difficulty of planning should not discourage this most important activity. 

A software product becomes better understood as it progresses through analysis, design and implementation; however, a software project should not be commissioned until enough information is available to permit preliminary planning.  It must be recognized that preliminary plans will be modified as the work products evolve; planning for change is one of the key aspects of successful planning.

Problem Description require techniques for gaining in depth knowledge in the concerned system and retrieving details of information required include customer interview, observation of problem tasks and actual performance of the tasks by the planner. 

The planner must be highly skilled in the techniques of the problem definition because different customer representatives will have different viewpoints, biases and prejudices that will influence their perception of the problem area.  With a knowledge retrieved from the above analysis it is able to formulate their problems in a manner that yield to logical, algorithmic analysis of the required system.

Goals and Requirements:

After a through analysis of the existing system and requirement form from the existing users, it is found that an entire new system is to be generated for preparing a well defined, computerized, automated Multi Room Chat so as to send messages to members pertaining to a group alone while you are participating in other private and public chat.

Chemical organization management system project idea in java explains about requirements and advantages of developing a software application for chemical industry.

Project overview:

• S Associates is a company located at naroda. It’s a manufacturing unit of Chemical and dyes. During the visit of this company we feel that the everything to maintain this unit is done on paper by the owner if the company. When we discuss with him regarding new technologies it comes to my mind to make everything computerized.
• The owner of the company has to do everything like payout of the labour, sales management, Purchase management, daily sheet, Company growth etc.
• We suggest him an application which is our “Chemical Organization Management System”.
• Here in the system it will work very smoothly and will provide the each functionality we discussed above.
• The labour payout system will help owner to make payout at the end of each month. It will keep track of all the labour and in the end it will help owner to make payout.
• The bill generator will help them to generate the bills and keep it record and inform the clients about it using message or mail system.
• The reports generator will generate reports on monthly basis so the owner can see the growth of the company frequently.
• Owner can store the products and their data and can also store its notes in the database and can open anytime during the next production.
• The purchase and sale is also done by the owner which is really too hectic to manage but now on word the purchase and sales management module will help owner to maintain purchase and sales.

Hotel management system project explains about how to develop a web application in java with booking , food ordering, bill generation, inventory and reports generation modules. 

Existing System Overview:

• Hotels are the place where you stay, eat meals and utilize their other services.
• As computer has merged with man as single entity so a computerized application can be developed that can handle Hotel Management System (HMS).

Various activities takes place in hotel like:-

• All the above activity takes place manually, manually carrying out this activity in very tedious time consuming. 

• As we have tried to develop computerized application so as to handle all the activity that takes place in Hotel. 

As all the activities that happen in the Hotel such as enquiry, check status booking, food order etc. can be handled on this system simultaneously.

Existing System

The existing system of Hotel Management was manual. All the daily routines is carried out manually and the records are maintained in the record books or the registers.

Booking:-    

The customer used to make enquiry for rooms available, and then depending upon the status he used to make booking. All the data the receptionist used to give the customer was based on paper works, there was no clear idea of the status of rooms as they did not update automatically.

Food Order:-

            The customer gives the food order to the waiter, and then the waiter pass that order to the food department. 

Bill Generation:-

          The clerk operates the bill department he used to generate the bill of the customer depending upon the services utilized by the customer.

Inventory:-

          The inventory manager manages the inventory as he checks the status of the inventory and as per that he order places the order. 

Report:-

          The administrator views all the report of the various departments, to check the progress of the hotel and to make the necessary changes. 

 Our aim was to built a Query Processing Projects on Database Engine based on Relational Model . But, we have to reduce to our work and we finally come with an application that processes quiet large number SQL queries like SELECT, INSERT, UPDATE, DELETE and evaluation of some complicated expressions on single table. The application is built in JAVA and we have used BlueJ as development environment.

We have used ZQL parser and modified its code as per our project requirements. 

 Applications

1. Persistent storage of data.

2.   Controlled redundancy.

3.   Support  queries of SELECT, DELETE ,  INSERT and UPDATE.

4.   Representation of some complex expressions like AND, OR , NOT , NOT  BETWEEN operators  on Single table . 

 Limitations   

1. Lack of Graphical user interface.
2. Joins not supported.
3. Works for Centralized Database only,  No support for client server   

 Future Directions 

Any data driven application will require the use of database engine. It  offers competitive performance in terms of speed, reliability and integrity with large number of expressions evaluation. Though, its scope is quite big. 

 1. It is limited to the centralized database, currently i.e. to a single user support. Here operations are performed on single table . 

2.  We can perform Join operations and use various optimization techniques like  heuristic approach and Cost based optimization for enhancing the performance of our application. 

3. Besides, we can use where other evaluations expressions like ORDER BY, GROUP BY , LIKE , NOT LIKE , COUNT, and other aggregate operations to extend the   performance of our application.
