PLEASE send me the dfd of seminar managenent system.in my project there are three module one for admin one for student and one for faculty .the admin module can login.edit and add the faculty.the faculty module can login ,edit,and register.as a new user.and upload the notes.and the student only register and give the topic of seminar plz send me the dfd (level 0 and level 1) of mu project.

INTRODUCTION
Student Management System is software which is helpful for students as well as the school authorities. In the current system all the activities are done manually. It is very time consuming and costly. Our Student Management System deals with the various activities related to the students.
There are mainly 3 modules in this software
• User module
• Student Module
• Mark management
In the Software we can register as a user and user has of two types, student and administrator. Administrator has the power to add new user and can edit and delete a user. A student can register as user and can add edit and delete his profile. The administrator can add edit and delete marks for the student. All the users can see the marks.
SYSTEM ANALYSIS
EXISTING SYSTEM:
System Analysis is a detailed study of the various operations performed by a system and their relationships within and outside of the system. Here the key question is- what all problems exist in the present system? What must be done to solve the problem? Analysis begins when a user or manager begins a study of the program using existing system.
During analysis, data collected on the various files, decision points and transactions handled by the present system. The commonly used tools in the system are Data Flow Diagram, interviews, etc. Training, experience and common sense are required for collection of relevant information needed to develop the system. The success of the system depends largely on how clearly the problem is defined, thoroughly investigated and properly carried out through the choice of solution. A good analysis model should provide not only the mechanisms of problem understanding but also the frame work of the solution. Thus it should be studied thoroughly by collecting data about the system. Then the proposed system should be analyzed thoroughly in accordance with the needs.
System analysis can be categorized into four parts.
 System planning and initial investigation
 Information Gathering
 Applying analysis tools for structured analysis
 Feasibility study
 Cost/ Benefit analysis.
In the current system we need to keep a number of records related to the student and want to enter the details of the student and the marks manually. In this system only the teacher or the school authority views the mark of the student and they want to enter the details of the student. This is time consuming and has much cost.
PROPOSED SYSTEM
In our proposed system we have the provision for adding the details of the students by themselves. So the overhead of the school authorities and the teachers is become less. Another advantage of the system is that it is very easy to edit the details of the student and delete a student when it found unnecessary. The marks of the student are added in the database and so students can also view the marks whenever they want.
Our proposed system has several advantages
 User friendly interface
 Fast access to database
 Less error
 More Storage Capacity
 Search facility
 Look and Feel Environment
 Quick transaction
All the manual difficulties in managing the student details in a school or college have been rectified by implementing computerization.
FEASIBILITY ANALYSIS
Whatever we think need not be feasible .It is wise to think about the feasibility of any problem we undertake. Feasibility is the study of impact, which happens in the organization by the development of a system. The impact can be either positive or negative. When the positives nominate the negatives, then the system is considered feasible. Here the feasibility study can be performed in two ways such as technical feasibility and Economical Feasibility.
Technical Feasibility:
We can strongly says that it is technically feasible, since there will not be much difficulty in getting required resources for the development and maintaining the system as well. All the resources needed for the development of the software as well as the maintenance of the same is available in the organization here we are utilizing the resources which are available already.
Economical Feasibility
Development of this application is highly economically feasible .The organization needed not spend much money for the development of t he system already available. The only thing is to be done is making an environment for the development with an effective supervision. I f we are doing so , we can attain the maximum usability of the corresponding resources .Even after the development , the organization will not be in condition to invest more in t he organization .There fore , the system is economically feasible.
