Develop a context diagram and level-0 diagram for the hospital pharmacy system described in the following narrative. If you discover that the narrative is incomplete, make up reasonable explanations to complete the story. Supply these extra explanations along with the diagrams. The pharmacy at Mercy Hospital fills medical prescriptions for all hospital patients and distributes these medications to the nurse stations responsible for the patients’ care. Prescriptions are written by doctors and sent to the pharmacy. A pharmacy technician reviews each prescription and sends it to the appropriate pharmacy station. Prescriptions for drugs that must be formulated (made on-site) are sent to the lab station, prescriptions for off-the-shelf drugs are sent to the shelving station, and prescriptions for narcotics are sent to the secure station. At each station, a pharmacist reviews the order, checks the patient’s file to determine the appropriateness of the prescription, and fills the order if the…

- This is a continuation to the question above. The directions continue as follows: Also, create a Use Case diagram. Make sure to identify the entities as actors and show the interaction between each of the actors. Be sure to identify at least two processes and show all the actions between them. Don't forget to include a system boundary so we can determine which actions occur within the system and which are external to SIM. With the creation of the use case diagram, you should be able to create a model (or table) showing each object. For each object, be sure to outline associated attributes and methods. Hopefully, the use case diagram and the DFD will make this process fairly straightforward. The developers need 3 instance examples for each of the entities. I suggest that you use the data library and previously developed organizational chart to find examples.arrow_forwardDevelop a context diagram and level-0 diagram for following case study: “Drugstore at Combined Military Hospital fills medical prescriptions for all hospital patients and distributes these medications to the nurse sections responsible for the patients’ care. Doctors write prescriptions and send them to the drugstore. A drugstore technician reviews each prescription and sends it to the appropriate drugstore section. Prescriptions for drugs that must be formulated within the hospital are sent to the lab section, prescriptions for off-the-shelf drugs are sent to the LP (local purchase) section, and prescriptions for narcotics are sent to the LP (local purchase) section. At each section, a pharmacist reviews the order, checks the patient’s file to determine the appropriateness of the prescription, and fills the order if the dosage is at a safe level and it will not negatively interact with the other medications or allergies indicated in the patient’s file. If the pharmacist does not fill…arrow_forwardDraw an E-R diagram to model the following situation. Be sure to include in your diagram all the relevant entities, attributes, relationships, functionality (N:1 or N:M) and whether any are mandatory. You can either draw the diagram by hand and submit it as a photograph/scan or you can create the diagram in a program with drawing tools (Word, Powerpoint etc.). Upload your diagram by the deadline. [HINT: There are 3 entities and 2 relationships in the model answer]. A bus depot includes a maintenance section that repairs faulty buses. Each bus is identified by its fleet number, its make, the year it was manufactured and its registration number. When a vehicle breaks down, a report is submitted describing the nature of the problem and the time when the incident occurred. These reports are consecutively numbered as they are received and include the time when the bus was returned to the depot for repair. One or more mechanics fix the bus. Mechanics are identified by their staff number,…arrow_forward

C1. , take a clear photo UTAS-Suhar Library head decided to build a new online library system to facilitate borrowing books for students anả instructors. So, the proposed system will allow the students and instructors to login to the system with their usernames and password and then the system will authenticate them to make sure that they are authorized people or not. Also, it will allow them to search for books by using book title or ISBN. In addition it will allow them to borrow a book for a specific period. Finally, when the due date arrives, they must return the books to the library and receive the confirmation receipt. The system also will allow the Liberian to check for the available books and order new books. The head of the Library will be able to…arrow_forwardTo do this, we'll compare and contrast the Rational Unified model with the more traditional Waterfall approach.arrow_forwardDrawing a Block Diagram and Flow Chart.

- Draw a single ER diagram that represents the specifications listed below. Follow the process below to help you do this: Consider a model of an airport with planes, models of planes, test of planes, and technicians. Draw an ER diagram to represent these entities and their attributes. Planes have a unique registration number. Airplane Models are each identified by a model number (e.g., DC-80, A380, B747), and each have a capacity and a weight. Several technicians work at the airport. You need to store for each technician the name, phone number, address, and salary. The airport has a number of tests that are used regularly to ensure that airplanes are safe. Each test has a unique FAA number, a name, and a maximum possible score. Extend your ER diagram with relationships to represent the following information. Each airplane is of one specific model. Each technician is an expert on one or more plane models. His or her expertise may overlap with that of other technicians.
