The application based on google maps API to find and manage blood donation volunteers

Most young Vietnamese people now have access to the movement of voluntary blood donation. Volunteers who want to donate blood must meet certain health requirements and wait at least three months between donations. As a result, the blood received falls below the bare minimum, resulting in reserve anemia. Based on these practical requirements, the article proposes a tool to assist health facilities in locating people willing to donate blood in hazardous situations within a reasonable distance. This system is built on a three-layer model that interacts with the database via Entity Framework and uses the Google Map API to locate blood donors. Before being used, the application was tested on a website using blood donation data from volunteers in the Binh Thanh and Go Vap districts.
