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…
Starting with a context diagram, draw as manynested DFDs as you consider necessary torepresent all of the details of the engineeringdocument management system described inthe following narrative. You must draw atleast a context diagram and a level-0 diagram.In drawing these diagrams, if you discoverthat the narrative is incomplete, make up rea-sonable explanations to complete the story.Provide these extra explanations along withthe diagrams.Projects, Inc. is an engineering firm withapproximately 500 engineers that providemechanical engineering assistance to organi-zations, which requires managing many docu-ments. Projects, Inc. is known for its strongemphasis on change management and qualityassurance procedures. The customer providesdetailed information when requesting a docu-ment through a web portal.

Develop a context diagram and a level-0 diagram for the contracting 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.
Government Solutions Company (GSC) sells computer equipment to federal government agencies. Whenever a federal agency needs to purchase equipment from GSC, it issues a purchase order against a standing contract previously negotiated with the company. GSC holds several standing contracts with various federal agencies. When a purchase order is received by GSC’s contracting officer, the contract number referenced on the purchase order is entered into the contract database. Using information from the database, the contracting officer reviews the terms and conditions of the contract and determines whether the purchase order is valid. The purchase order is valid if the contract has not expired, the type of equipment…

- 2. Develop a context diagram and level-1 diagram for the hospital pharmacy system described in the following narrative. The pharmacy at Hopeful 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 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…arrow_forwardCan you draw a DFD diagram for Levels 0 and 1? When constructing the initial DFD level 0, create it so that the workers of that children's daycare have a time stamp that informs them the timetable of their presence and allows them to check in and out. Make it such that it is sent to the manager both during and after work. Also, create a Level 1 DFD that defines the entire daycare system and how it runs, and then create a Level 2 DFD diagram to improve it and establish the fundamentals of what to accomplish.arrow_forwardThis 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_forward

State any assumptions, if you have anyThe purpose of the Auto Insurance system is to provide automotive insurance to car owners. Initially, customers are required to fill out an insurance application. A driver’straffic record request is requested from the local police department. The agent determines the best policy for the type and level of coverage desired and gives the customer a copy of the insurance policy proposal and quote. If the customer accepts, he or she pays the initial premium and is issued both the policy and a state-required insurance coverage statement (a card to be carried at all times when driving a vehicle). The customer information is now stored. Periodically, a premium notice is generated, which—along with policy coverage changes—is sent to the customer, who responds by sending in a premium after which new insurance coverage…arrow_forwardThe system boundaries and context model may experience serious cost and complicity implication if theyare not well created and defined. Give two (2) examples where this may be applicable.arrow_forward
- We need to be able to describe systems to assist with development, to assist with use, and to assist with maintenance. To that end, diagrams provide a concise, semi-formal way of describing a system. Data flow diagrams are an important tool in the development of information systems. Below are descriptions of Context diagrams, Physical Data Flow Diagrams, and Logical Data Flow Diagrams. Please fill in the missing words in the spaces provided. Context Diagrams are top-level, least-detailed diagrams of an information system. They provide the system’s context in relation to the data flows ____ and _____ of the system and _____ and _____ of the external entities. Physical Data Flow Diagrams describe graphically the system’s internal and external entities (things), and the data flows into and out of these entities. Physical Data Flow Diagrams depict _____, _____, and by _____ a system’s processes are accomplished, however they do not indicate _____ was done. Logical Data Flow Diagrams…arrow_forwardCompare and contrast a context diagram with a diagram 0.
