Working paper

Blood banks and hospitals require accurate donor information, reliable inventory records, and timely processing of blood requests. Manual record-keeping can create data-entry errors, make it difficult to locate suitable blood units during emergencies, and delay stock updates. This paper presents the design of a Blood Bank Management Portal intended to centralize donor registration, blood inventory monitoring, blood request handling, emergency blood search, and low-stock notifications. The project is framed as a basic public-service system that supports efficient blood-bank operations. The proposed portal uses a role-based interface for users such as donors and administrators, with a centralized database for maintaining records and request history. The project materials identify Firebase Firestore as the configured data store for entities including users, donors, blood batches, blood requests, audit logs, and system configuration. The portal is intended to improve record consistency and visibility of available stock, reduce routine administrative effort, and support faster responses to requests. This paper describes the problem, related systems, proposed methodology, architecture, expected outcomes, limitations, and future enhancements. Quantitative performance results are not claimed because controlled evaluation data were not supplied.
