DESIGN AND IMPLEMENTATION OF AN ONLINE BLOOD BANK MANAGEMENT SYSTEM

Thesis Overview

INTRODUCTION

System Development:The process of building systems has always been complex with system becoming larger, the costs and complexities get multiplied. So the need for better methods for developing systems is widely recognized to be effective and the applied model should meet a few basic requirements.

• The model should be structured and cover the entire system development process from feasibility study to programming, testing and implementation.
• The model should utilize established methods and techniques like database designs, normalizations and structured programming techniques.
• The model should consist of building blocks, which define tasks, results and interfaces.
• The model should separate the logical system from the physical system.
• Documentation should be a direct result of the development work and should be concise, precise and as non-redundant as possible.

Based on the above requirements of the system model, system study has been made. Various methodologies have been applied for system study, evolving design documents, data modeling, input screen design and report design.Project:The persons who like to donate blood registers in my site as well as he can modify the details if necessary, giving the Login Id and Password. The persons in need of blood searches for the persons having the same blood group and with in the city. If he found a donor in his city then he gets the total details of the donor, if he doesn’t find any donor then he is given the contact numbers and addresses of the Life Saving Contact Persons for major cities. If he doesn’t have any chance to contact them then he will be provided with Mobilink Paging Services in order to get the blood.

SYSTEM ANALYSIS

Preliminary Investigation:First in the system development process is preliminary Investigation. Preliminary Investigation is conducted in the following phases.

• Project clarification
• Feasibility study
• Project appraisal

Project clarification is the process of selecting a project request for further study. When a system development or modification request is made, the first systems activity, the preliminary investigation, begins the activity has three parts: Request clarification, feasibility study and project appraisal. Many request from employees and users in organization are not clearly stated.Therefore before any systems investigation can be considered,  the project request must be examined to determine preciously what the originator wants. This is called Request clarification.As important outcome of the preliminary investigation is the determination that the system request in feasible.

Feasibility Study:

The feasibility study is performed to determine whether the proposed system is viable considering the Technical, Operational and Economical factors. After going through feasibility study we can have a clear-cut view of the system’s benefits and drawbacks.Technical Feasibility:The proposed system is developed using Active Server Page, VB Script and HTML as front-end tool and Oracle 8 as the back end. The proposed system needs a Personal Web Server to serve the requests submitted by the users. The Web browser is used to view the web page that is available within the Windows operating system itself. The proposed system will run under Win9x, NT, and win2000 environment. As Windows is very user friendly and GUI OS it is very easy to use. All the required hardware and software are readily available in the market. Hence the system is technically feasible.Operational Feasibility:The proposed system is operationally feasible because of the following reasons.

• The customer is benefited more as most of his time is saved. The customer is serviced at his place of work.
• The cost of the proposed system is almost negligible when compared to the benefits gained.

Economical Feasibility:As the necessary hardware and software are available in the market at a low cost, the initial investment is the only cost incurred and does not need any further enhancements. Hence it is economically feasible.The system is feasible in all respects and hence it encourages taking up the system design.Gathering Information:The analysis through collection of data plays the wider role in the analysis of the system. So the data is collected at different levels of management to keep track of full information of the system.The collection of data is done from:

• Top Level Management
• Middle Level Management
• Low Level Management

Different methods used to collect the data:Questioners:The data is collected through questioners by filling a set of questions from the different levels of management. The questions made by questioners are three different types.They are,Structured questioners:                            Unstructured questioners:                            Semi-structured questioners:Interviews:Interviews were conducted to collect the information. The interviews were conducted at two levels.

1. Formal Group Interviews:  the interviews conducted for formal groups i.e., the hierarchical (official) groups in the firm.
2. Informal Group Interviews:  the interviews were conducted for informal groups   i.e., the groups formed out side the company.

Observation:The data is also collected by observation of the firm. The data is collected by observing on the site at different timings and at different situations like when the firm is busy and when the firm hasn’t much work to do.Record Review:To collect the data and to get a clear idea of the firm some of the data is also collected from the past records of the firm. This information helps very much to get a clear idea of the firm i.e., the different problems occurred in different seasons and some exception conditions. This very much gives a clear idea of exceptional conditions.System Study:Present system:There are certain features limiting the process of the present system.The drawbacks of the present system are listed below.q  The increase in number of vehicles now a days.q  The increase in number of accidents now a days.q  The patients cannot get the information of donors easily.Proposed system:The proposed system, Online Blood Bank site overcomes the drawbacks of the present system. The Blood Bank helps the people who are in need of a blood by giving them overall details regarding the donors with the same blood group and with in their city.The advantages of the proposed system are listed below.q  The people in need of blood can search for the donors by giving their blood group and city name.q  It is very flexible and user friendly.q  The person’s time and work is reduced very much which prevails in the present system.q  Easy and Helpful.q  The people are not limited to receive or provide services in working hours of the branch only; he is serviced 24 hours a day, 7 days of week and 365 days of the year.Limitation:q  In this project the searching can be done for donors for majority of cities but not for every city.q  In this project the contact person’s details are given for the limited cities only.
