REQUIREMENT ANALYSIS
Project Scope:
To provide online education courses.
To provide online study material .
To provide various online examinations.
Assumptions:
Every student must register himself.
Student must read study materials.
Module wise description
Module 1: Sign Up():In this module the new user will successfully get registered to the site.Here the user will get registration form asking for information about the user. Once the user will enter all the information on form & click on submit button the user will become the registered user of the system.
Module 2: Sign In():
In this module the registered user can sign in to his account. This module will provide sign in window asking for registered user name & password. Once the authorized user entered his username & password the user will move to select course page.
Module 3 :Select Course():
This module will provide the registered user options for selecting any of the available course.So that the user can select one of the language course.
Module 4: Study Material()
This module will provide the user study material required for the language course. So that the user can study the syllabus & can make himself prepared for giving examination.
Module5: Examination()
In this module the registered user can give examination on the selected language course. Here questions are present on this screen with four options as soon as the user will select one option the answer will submitted & after finishing the questions the result will be calculated.
Module6: Result()
In this module the result of the examination will be displayed to the user. Read More......
1.3 System Requirements
Hardware requirements
Hard Disk : 10GB Onwards.
RAM: 256 MB.
Processor Pentium III onwards.
Software requirements:
Operating System : Windows 98 n onwards.
Java 1.4.
MS-Access
Any Web Browser
Apache Tomcat 5.0
1.2.4 Schedule Feasibility
This involves questions such as how much time is available to build the new system, when it can be built, whether it interfaces with normal business operation, number of resources required, dependencies, etc. Contingency and mitigation plans should also be stated so that if the project does over run the company is ready for this eventuality
Read More......1.2.3 Operational Feasibility
This involves questions such as do the current work practices and procedures support a new system? Also social factors i.e. how the organizational changes will affect the working lives of those affected by the system.
The system will be used if it is developed and implemented, training of user, actual place of implementation & expenses of training program are considered to see if it is operationally feasible for the organization. It is carried by small number of people familiar to information system, techniques and rules of business organization. The person must be skilled and experienced in system analysis and design process.
1.2.2 Economic Feasibility
This involves establishing the cost-effectiveness of the proposed system i.e. if the benefits do not outweigh the cost then it is not worth going ahead.
Here the actual cost involved in the proposed system is calculated. It checks the cost benefit from the new system to the organization. It considers if the system’s tangible and intangible benefits are acceptable or not.
1.2.1 Technical Feasibility
This involves questions such as whether the technology needed for the system exits, how difficult it will be to build, and whether the firm has enough experience using that technology. The assessment is based on an outline design of system requirements in terms of Input, Processes, Output, Fields, Programs, and Procedures. This can be qualified in terms of volumes of data, treads, frequency of updating, etc. in order to give an introduction to the system.
It considers if it is possible to develop a system on available hardware, software & manpower. It takes into consideration cost of hardware, software & technical equipment to see if the proposed system is technically feasible or not.
Feasibility Study
A feasibility study is a preliminary study undertaken to determine and document a project’s viability. The term “feasibility study” is also used to refer to the resulting document. These results of this study are used to make a decision whether to proceed with the project, or table it. If it indeed leads to a project being approved, it will – before the real work of the proposed project starts-be used to ascertain the likelihood of the project’s success. It is an analysis of possible alternative solutions to a problem and a recommendation on the best alternative. It, for example can decide whether an order processing be carried out by a new system more efficiently than the previous one.
A feasibility study could be used to test a proposal for new system, which could be used because:
The current system may no longer carry its purpose.
Technological advancement may have rendered the current system obsolete.
There is increase in cyber crime .
Customers are complaining about the speed and quality of work the business provides.
A Feasibility study should examine three main areas:
Legal issues
Technical and organizational requirements
Financial overview
Within a feasibility study, major areas must be reviewed, such as:
Technical Feasibility
Economic Feasibility
Operational Feasibility
Schedule Feasibility
SYSTEM STUDY
1.1 Project Definition
Distance Learning System is software which will help us to provide various computer
courses online with examination based on that course.
