7 COMMUNICATION SYSTEM FOR CSE DEPARTMENT 1. INTRODUCTION According to the Wikipedia : Communication (from Latin commūnicāre, meaning "to share" ) is the activity of conveying information through the exchange of thoughts, messages, or information, as by speech, visuals, signals, writing, or behavior. It is the meaningful exchange of information between two or more living creatures. [1] Simply the process of conveying information between two parties is termed as communication. The communication between any two parties may be one or the two ways. As the use of Information Technology (IT) in the communication is growing, Web-based systems are used as an effective tool for communication purpose. The use of Internet and World Wide Web (www) in the field of communication systems are one of the most important development in the history of computing. They have become integral part of our daily life. As Computer Science students, we have attempted to make use of the Web Engineering Principle in our project. The main objective of our project is to assist the existing communication system in nec CSE Department with a Web-based system. This system ensures easy and effective communication between teachers, students and department. Students can download study materials, view department updates, notices, results, class routines and important upcoming events. They can also join a chat room to discuss their course related problems with their colleagues or subject teacher. Teachers can upload/download course materials, internal marks and answer to student s questions. Collectively, we have developed a responsive and user interactive website that is simple and user-friendly OBJECTIVES To develop a web based platform for teachers and students of nec, CSE Department.

8 2. LITERATURE REVIEW [1]The University of Kansas (KU) Online Learning Center is one of the world s largest web based learning center. This distant learning system is designed for those who can t regularly attend class in university due to physical, social or economic boundaries. This site contains thousands of Lecture videos and other reading materials relevant to the courses provided by the university. Students can submit their queries about the course and they are helped by particular subject expert. They can also appear in online examination and got degree without going to university. This is one of the best examples of use of technology in education. Internet and World Wide Web are one of the most influential technologies that have been developed so far. The learning system has made the use to this technology for the welfare of the student and to help them pursue their dream of having college degree. This is very large system and designed to support thousands of users at a time. It also contains a large variety of study materials and there are experts available to solve problems submitted by the students. But in our system, we are concerned only with serving limited number of users at a time (few hundred only) and we will not have experts always available to solve student s academic problem. Instead, student will submit their problem in a forum and it will be discussed and solved by other fellow students or teacher. One extra thing we have incorporated in our system is chat system i.e. there is a provision of real time chat between logged in users at a time. [2] The vast use of the Web for the communication system had led to the development of many web pages. KOHINOOR ACADEMY is the web based software which functions as the academic information system and also processes daily academic operation in Nepal. This also functions as the administration of the educational institutions. Kohinoor academy commits to be applicable for every schools and colleges. This system has features of managing many sectors related to the college like library, student information, classes and exam scheduling, marking, attendance management, administration management. In our system we are only concerned with Computer Science and Engineering Department of nec and we are not concerned about library, account and other department of the college. [3] MIT open course ware in another online learning system. The course materials are provided to all the student and teachers who log in to the system. It has large numbers of course materials and covers hundreds of course provided worldwide. This system is has made it possible for the student from any corner of the world the easy excess to the quality and trusted study materials and works as their distant instructor. 2

The server controls all the internal structure of the system and also controls the database and provide access to the clients. General system Architecture End user Client system application Client system Network (wan) system Database system Server Figure 1 : general system architecture 3

10 3.2. METHODOLOGY For the development of our system we first analyze the existing problem in the CSE department of nec. After the proper analysis of these problems, we designed some model for the simplification of the problem. We refer different websites to know whether the similar system exists or not. The designing and the process modeling was done and followed by construction and testing SDLC MODEL The software development model used for this system design is RAD model. The RAD model is similar to the waterfall model but the RAD model uses less development period. RAD uses component based construction and emphasizes reuse and code generation.

20 5.5. SUBSYSTEM MODULE 1) Search Module Figure 10: Search Module The diagram above shows the sequence diagram of search module. Here after the user got logged in, the user search for the specific document. And the searched file is checked for the availability in the database by the system. If the file is available in the database then the system shows this searched file to the user. Also the system asks the user for its download. The user can only view or download the file. 14

21 2) Login/Register Module Figure 11 : Registration/Login Module The login module for our system is shown in the diagram. At the initial phase the user get to the login page. The login page has two provisions first register and second as login. If the user is new, he/she has to create a valid username to get access to the information from the page. The validation of the username and the password is checked by the system. If the input information is approved by the system, the users get registered. Similarly the users with valid user id can get logged in by the processing of username and password. After the login the user are capable of accessing data. 15

22 5.6. TESTING Software testing can be stated as process of validating and verifying that a computer program, application, product and performance meet the requirements and works as expected. Unit Testing Unit testing tests the functionality of specific unit, functions in modular programming. It is also known as components testing, refers to tests that verify the functionality of specific section of code, usually at the function level. The expected and actual outputs are asserted by feeding various inputs via different test cases. We have implemented the unit testing in some of the functional part of our system is shown below: Testing for Login S.no Test Test Case Input Result Message Remarks 1.

27 6. CONCLUSION The core objective of the development of this system is to create the common platform for the communication between teachers and the students. The system uses the electronic method for the communication. The networking and the computer devices are the basic components for the communication between two parties. There are three different user involved in the system they are admin as the controller and other two user faculty member (teacher) and students. The system is supposed to be helpful for the academic section, since the study materials can be accessed in simpler way. And all the notices and the updates about the college can be viewed in the single platform. We have attempted to reduce the unwanted error in the system. But it can t be sure that we have removed all the bugs in the system. And some assumptions were made while developing the software so which may encounter some errors. We also had tried to make the user interface friendlier using the proper combination of color, menu position, picture combination and many others. So in general the system Communication system for the CSE department can be the effective means of communication within the limited field. 7. LIMITATIONS Every existing system may not perfect, but the system may be useful for limited actions. Similarly we too have attempted to include many of the features but it is not possible to provide the entire feature in this short period of time. Also the assumption in the system limits the features provided. The system was developed for the communication between the nec CSE department, so we can t use the system in other departments. Also all the information about the faculty can t be provided because some privacy in the faculty must be maintained. There is the inter communication of CSE with other departments like exam department, accounting department, student welfare department etc, so the communication between these department cannot be included. We have limited the area of working space. 21
