Blood Donation System (Software Engineering - UML Diagrams)

It's a work for Blood Donation System that include 3 phases: Introduction, Requirements and UML Design.

First Phase contains Abstract, Introduction, Problem Definition, Proposed Solution, Software Development Process and Feasibility Study.

Second Phase contains Requirements (Functional requirements & Non-functional requirements (NFR)).

Third Phase contains Use Case Diagram of the system, detailed description of three of its use cases (including sequence diagrams for Donor, Requester and the whole system), Class diagram of the system that include object attributed and objection actions and Activity Diagram in addition to description of all of these diagrams. It's an accurate system analysis work. I can add more features if you want.
