Use case diagram for a blood bank system

About this use case diagram for a blood bank

The blood bank system use case diagram has five key actors. They connect with the main system processes through clear links. The donor actor interacts directly with the system through three main functions. The first is the register donor, which begins the process of adding a donor’s details into the system.

After registering, the donor joins a scheduled donation. This means picking a good time to donate blood. The donor then proceeds with donating blood, completing the main contribution activity. These interactions shape the donor’s entire cycle in the blood bank system.

The patient actor communicates with the system through three connected use cases. The first interaction happens with a request for blood. Here, the patient asks for a specific blood type or unit. The patient checks the status. This helps them see the progress or approval of their request. In hospitals, a patient can make an urgent hospital request. This request connects to the blood supply process. It helps speed up communication between medical institutions and the system.

The hospital actor connects with two major processes: requesting blood and registering hospital. Hospitals connect to manage the blood supply and set up registration in the system. The admin actor uses the generate report. This function compiles operational or donation records in the blood bank.

The blood bank actor has two main functions: Approving blood requests and managing inventory. These functions help control supply and manage records. Each actor has unique roles, but they work together. They ensure a smooth flow of donations, requests, approvals, and management. This links donors, patients, hospitals, administrators, and the blood bank into one system.
