## 6 Conclusions  
The blood bank management system is a 24/7 system beneficial to blood banks, medical centers, and hospitals, which can maintain all information via multiple technologies. Unfortunately, many traditional blood banks depend on a paperwork-based system that struggles to supply the required blood in emergencies. This study aimed to design a practical system using Web technology and IoT technics to improve and organize the performance of blood bank management. The study method began with information and requirements gathered from the Central Blood Bank of Salah ad-Din, which was the actual case study. Then, we undertook an analysis of the existing system to detect the problem. The software and hardware tools were selected in the design and implementation step to build the Web app (IRW). Finally, the proposed system was tested and evaluated. The proposed system was tested successfully and achieved good results based on functionality and usability testing. The responses highlighted the satisfaction, efficiency, and effectiveness of the system. Moreover, the results indicated that the system significantly reduced the average waiting time for patients and provided better monitoring regarding blood validity and required quantity level. * The advantages of the proposed system: 1. It is an intelligent system that helps to facilitate blood bank work that is performed by the manager or medical employee in order to reduce mistakes and keep the blood quantity in as regular a range as possible; 2. It helps in providing and managing the blood, especially the rare blood groups needed in emergency situations without delay; 3. As the system's implementation complexity grows, it may become difficult to manage by medical staff. The proposed system employs an easy method; 4. The proposed system helps to save the costs because it alerts in real time if there is any damage or problem, such as a shortage of inventory quantities, especially rare blood groups, malfunctioning blood storage refrigerators, or electrical current issues. This contributes to reducing financial losses, preparing in advance, and developing alternative solutions. * The authors offer the recommendations below: For medical institutions: 1. Using such an intelligent system in the central blood banks and branch centers all over the country will help to reduce the problems that paper-based blood banks have long faced via the assistance of its simple, practical design and ease of use; 2. Intensifying awareness and promotional and advertising campaigns to educate citizens, inform them of the importance of donating blood, and motivate them to contribute on an ongoing basis. For researchers: 1. Given the importance of providing the appropriate blood types, especially in emergencies, serious work must be carried out to provide automated computer systems and applications (Web or mobile); 2. Social media must be used to share the donating experience and donation information to spread awareness. The most popular social media sites are Twitter and Snapchat; 3. The integration of the main and subsidiary centers in the area must be strengthened through the design and implementation of appropriate applications and systems to avoid dangerous problems; 4. The privacy and confidentiality of users must be considered during app design and development; 5. There is no doubt that maintaining a healthy blood inventory during the preservation period is a significant challenge.
