Query Handling System

3QUERY HANDLING SYSTEM

Abstract:• This project is designed for college students

to get clarify their doubts by posting their queries.

• The queries posted by the students are handled by the administrator.

• The administrator answers the queries posted by students.

Objective Of The Project:

• The primary goal of the query handlingsystem is to provide an environment thatis both convenient and efficient for thestudents and lecturers.

• It also provides the safety to theinformation stored, despite system crashesor attempts of unauthorized access.

Existing System:

• The existing system is manual one.• When the students want to clear there

doubts they personally contact the concerned person in the college.

Disadvantages:• Difficulty in contacting the concerned person.• Difficult to handle more students requests for

faculty.• Difficulty in maintaining frequently asked

questions manually.

Proposed System:

• Proposed system has one super user to control the data, appointing the administrators in each department.

• The administrator is responsible to answer all the questions posted by students.

Advantages:• Faster processing when compared to existing

one.• Easy in maintaining frequently asked questions.

Advantages Contd…

• Modifications of answers can be carried out immediately.

• Faculty can handle more number of students requests.

• Easy maintenance of faculty and student details.

Modules

The project contains three modules:• Super User• Administrator• Student

Super User

Super User performs the following functions:• Controls the data.• Registers the administrators and appoints

them in each department.• Add/delete departments like physics,

computer science, etc..• Adding the question with answers and

storing the data in database.

Administrator

• The student post a question in certain department and the respective administrator will answer the question and copy of the answer will be sent to the student.

• If there is any modification to be carried out in the answers administrator will modify the answers.

Student

• Student post a question in certain department.• Student check the answer for which he posted.• Student checks the answers for available

questions.

Feasiblility Study

• An important outcome of preliminary investigation is the determination that system required is feasible.

• Since data is voluminous and involves a lot of overhead.

• Therefore it is best activity for computerization.

• The proposed system is feasible in following aspects.

Technical Feasibility

The proposed system is technically feasiblesince the equipment,software technology and

available personal in the organization are well suitable for the proposed system.

Operational Feasibility

• The operational feasibilty system is measured by the usage of the system after implementation and resistance from the users.

• Hence it is encouraging to undertake a detailed system analysis.

Economical Feasibilty

• Since necessary hardware and software are available in the organization,there is no need to procure and install new hardware and software.

• Thus there is no need of extra personal on the proposed system.

• Hence the proposed system is economically feasible.

Solution Handler

Web User Interface:• Web user interface will provide the interface

to the user to communicate with the system.

Query Handling System Handler:• “Query handling services” maintains various

frequently asked questions posted by the students and keeps them in a database so that it can be retrieved easily by students when the admin answer that question.

Login Management Handler:• This block helps for authentication of user and

also changing the password.

Database System:• This block helps us to store the data or retrieve

the data from database.

Solution handler:• This block helps to store and retrieve the solution

for particular query. Also helps to modify the solutions.

Post Query Handler:• This block helps for handling various

frequently asked questions posted by students.

Department Handler:• This block helps for handling different

departments like computer science ,maths etc…Registration Form Handler:• This block helps to register the faculty members

for answering the questions posted by students. As well as it also helps to register the students.

System Specifications

Software Requirements:

• Operating system : Windows XP

• Programming Platform : j2sdk

• Backend Database : Mysql

• Server deployment : Apache Tomcat

Hardware Requirements:

• Processor : Pentium IV or higher

• Hard disk : 160 GB

• RAM : 1 GB

Testing

• Software testing is a critical element of software quality assurance and represents the ultimate review of specifications,design and coding.

• Testing presents an interesting anomaly for the software engineer.

Testing Type Methods

Unit Testing:

• Unit testing focuses verification effort on the smallest unit of software design that is the module.

• The unit test is normally white box testing oriented and steps can be conducted in parallel for multiple modules.

Integration Testing:

• The objective is to take unit tested methods and build a program structure that has been dictated by design. It is of two types

1.Top down Integration:

• It is an incremental approach for construction of program structure.

• Modules are integrated by moving downward through control hierarchy,beginning with the main control program

2.Bottom Up Integration:

• This method as the name sugggests,beginsconstruction and testing with atomic modules i.e., modules at the lowest leveling of program structure.

• The modules are integrated in bottom up manner.

Validation Testing

• Validation testing is the next stage which can be defined as successful when the software functions in the manner reasonably expected by the customer

System Testing:

• System testing is actually a series of different tests whose primary purpose is to fully exercise the computer-based system.

Recovery Testing:

• It is a system test that forces the system to fail in a variety of ways and verifies that the recovery is properly performed.

Security Testing:

• Attempts to verify the protection mechanisms built into the system.

Perfomance Testing:

• This method is designed to test runtime perfomance of software within the context of an integrated system.
