Design an ER schema for prescription monitoring based on the given data: Patients are defined by an identity number, a first name and a last name, and by a birth-date. Doctors are defined as well by an identity number, a first name, a last name, and a birth-date, while additionally they will be characterized by a work start date and a specialty. Pharmaceutical companies will be defined by a name, and a telephone number. Medicines will be defined by a commercial name, their manufacturer, and their active ingredient. Pharmacies will be defined by a name, an address and a telephone number. Each patient has one doctor and each doctor has at least one patient. A doctor can prescribe certain medicines to his patients. Each pharmacy sells several medicines, each at a specific price. Each medicine can be sold by several pharmacies possibly at a different price. Pharmaceutical companies have contracts with pharmacies. Each pharmaceutical company may have contracts with several pharmacies. Each…

In this unit, we explore the structured approach to modeling business processes. In this practical assignment, using the business process of a fictional package delivery service (a courier company) called On the Spot Courier Services, you will create data flow diagrams that demonstrate the business processes that would need to be supported by a new system. Scenario: When Bill got an order, at first, only on his phone, he recorded when he received the call and when the shipment would be ready for pickup. Sometimes, customers wanted immediate pickup; sometimes, they were calling to schedule a later time in the day for pickup. Once he arrived at the pickup location, Bill collected the packages. It was not uncommon for the customer to have several packages for delivery. In addition to the name and address of the delivery location, he also recorded the time of pickup. He noted the desired delivery time, the location of the delivery, and the weight of the package to determine the courier…

MAKE AN ER DIAGRAM FOR THE FOLLOWING PROMPT: Various physicians are working for a clinic and these doctors are identified by their respective employee numbers. The other descriptors of a doctor are: name, gender, address, and phone. Each physician’s specialty and rank are captured. Every physician serves as a primary care physician for at least one patient; however, no more than 20 patients are allotted to a physician. Every patient is assigned one physician for primary care. Data for patients include: patient number (the unique identifier of a patient), name, gender, date of birth, blood type and the code and name of allergies, if any. Physicians may prescribe medications to patients; thus, it is necessary to capture which physician(s) prescribe(s)s what medication(s) to which patient(s) along with dosage and frequency. In addition, no two physicians can prescribe the same medication to the same patient. If a physician leaves the clinic, all prescriptions written by that physician…
Create an ER diagram that correctly describes the database for exams at Campus in Bäcksvängen in accordance with the following description: (Own assumptions must be clearly described.) Staff for various functions are involved in the exams. All staff have a full name and a unique staff code. Some people are examiners on one or more courses. A course has one name and one unique ladok code. For a course, you can add up its points based on the associated elements. One part is part of a course (for example an exam, a laboratory or project). A course can have several different parts. An element has a name, a description, a torque code, one point and two or more grades (eg: U, G, VG). An element can only belong to one course. Since the database is to process the exams, it is obvious that a part like described as an examination has an examination opportunity that is identified, among other things, by the date, start time, end time and that it is possible to calculate total writing time.
