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…
Entity-Relationship Diagram (ERD) is one of the data modeling tools that provides
a software engineer with the ability to represent data objects, their characteristics,
and their relationships. Use an ERD to describe the following scenario.
A teacher is identified by an ID number (TID), last name (LName), and first
name (FName).
A project is identified by a project ID (PID) and title (T).
A student is identified by an ID number (SID), last name (LName), and first
name (FName).
A teacher can supervise zero, one, or many students and a student is supervised
by one teacher.
A teacher must propose one or many projects and every project is proposed by
one teacher.
A student must work on one project and every project is worked by only one
student.

- Please find the question below and help me with the answer?arrow_forwardneed diagram only Draw an ER diagram for the following scenario: A designer has a store of designer dresses both for male and female. People can buy as well as take dresses on rent from the store. Each dress in the designer's store, is identified by unique ID. A dress in the store can be categorized into various categories Western, Indian, Indo-westem, etc. The designer maintains the name, phone number of people who have taken dresses on rent. The designer also maintains the name, phone number, and address of people who have bought dresses from the store. The designer also collects feedback from the people who have bought or taken dresses on rent from the store. Design the ER diagram by mentioning all the structural constraints. You may also include additional information in addition to the requirements listed.arrow_forwardLet's say you wish to train and assess a classifier using just a little amount of data.

- Prepare an E-R diagram for a Aqarat (real estate) Company that lists property for sale. The following describes this organization: The company has a several number of offices. Attributes of office include Office_Number (identifier) and Location. Each office is assigned one or more employees. Attributes of employee include Employee_ID (identifier) and Employee_Name. An employee must be assigned to only one sales office. For each office, there is always one employee assigned to manage that office. An employee may manage only the office to which she is assigned. The company lists property for sale. Attributes of property include Property_ID (identifier) and Location. Components of Location include Address, City, State, and Zip_Code.

- 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.

Suppliers have names and IDS. Each component has ID, name, description, suppliers who supply them, and items in which they are used. Not all suppliers provide components, and a component is not always associated with a supplier. Also, a component always have to be associated with one or more items. Finally, the company contact customers using their IDs, Names and Phones to sell them items. A customer can buy one or more items.arrow_forwardWhat is the difference between a recurring group and an attribute that may take on many values?arrow_forward

It should include at least customers, checking accounts and loans, and appropriate relationships between them. Note: To keep this to a resonable size, you should limit yourself to at most six entities and at most eight attributes per entity.arrow_forwardDraw a complete ER-diagram for the following case. A lecturer (having an ID, name and room number) is responsible for organizing a number of course modules. Each module has a unique code and also a name and each module can involve a number of lectures who deliver part of it. A module is composed of a series of lectures and sometimes lectures a on a given topic can be part of more than one module. A lecture has a time room and date and is delivered by a lecturer and a lecturer may deliver more than one lecture. Students, identified by number and name, can attend lectures and a student must be registered for a number of modules. We also store the date on which the student first registered for that module. Finally, a lecturer acts as a tutor for a number of students and each student has only one tutor. Also show relational database schema including Primary and Foreign key constraints.
