Blood bank management system project report.pdfKamal Acharya The main objective of the “Blood Bank management System” all the details in the Blood
Bank’sprocess. This project has some tasks to maintain the Blood Bank through computerization.
Using this blood bank system people can search blood group available which they are needed.
They check it on using our blood bank management website. If in case blood group is not available
in blood bank they can also contact numbers of the persons who has the same blood group he is
need. And he can request the person to done the blood for saving someone life.
The Project describes the smart Blood Bank management system. This report will help you
to know in deep the actual work that has been done as a team work. The main objective of this
application is to automate the complete operations of the blood bank. They need to maintain
hundreds of thousands of records. Also searching should be very faster, so they can find required
details instantly. Main objective is to create a system which helps them to complete their work
faster in simple way by using computer not the oldest way which is used paper. Also our project
contains updated information and many things else.
The project consists of a central repository containing various blood deposits available
along with associated details. These details include blood type, storage area and date of storage.
These details help in maintaining and monitoring the blood deposits. The project is an online
system that allows checking weather required blood deposits of a particular group are available in
the blood bank. Moreover the system also has added features such as patient name and contacts,
blood booking and even need for certain blood group is posted on the website to find available
donors for a blood emergency. This online system is developed on PHP platform and supported
by an MYSQL database to store blood and user specific details.
