- The company is organized intoDEPARTMENTs. Each department has a name, number and an employee who manages the department.Each department controls a number of PROJECTs. Each project has a name, number and is located at a single location.We store each EMPLOYEE's social security number, address, salary, sex, and birthdate. Each employee works for one department but may work on several projects. ER diagram??To manage the materials of a factory, please give the E-R diagrams. Such entity sets are involved as below: Warehouse: with attributes as Number, area and telephone Accessory : with attributes as number, Name, Specification, price and description Supplier: with attributes as Number, name, address, telephone and асcount Project : with attributes as number and budget Employee : with attributes as number, name and ageThe entity type STUDENT has the following attributes: Student Name, Address, Phone, Age, Activity, and No of Years. Activity represents some campus-based student activity, and No of Years represents the number of years the student has engaged in this activity. A given student may engage in more than one activity. Draw an ERD for this situation. What attribute or attributes did you designate as the identifier for the STUDENT entity? Why?
- You are given an E-R diagram with two entities Orders and Customers. What does the lone between the Customers entity and the Place relationship represent?Question: a) Draw the entity relationship diagram for each of the following Scenario. i) The company has over 100 employees. Each employee is identified by their Employee_ID. Other attributes are Employee_Name, EmployeeAddress, and Skills. An employee may have more than one skill. And each skill can be mastered by many employees or none. ii) A customer can submit orders to buy products. Each order is identified by Order_ID, and Order_Date. A customer may submit any number of orders. Each order is submitted by exactly one customer. The identifier for a customer is Customer_ID. Other attributes include Customer_Name and Customer_AddressShow that you understand the Entity-Relationship Model and how it works.
- Question 2 Create an Entity Relationship Diagram for the following narrative. Bestari Auto dealership based in Kuala Lumplur sells imported cars. The dealership keeps information about each car manufacturer with whom it deals so that employees can get in touch with the manufacturers easily. The dealership also keeps information about the models of cars that it carries from each manufacturer. It keeps such information as list price, the price the dealership paid to obtain the model, and the model name and series (e.g. Audi Coupe R8). The dealership also keeps information about all sales that it has made (for instance, employees will record the buyer's name, the car the buyer bought, and the amount the buyer paid for the car). To allow employees to contact the buyers in the future, contact information is also kept (e.g. address, phone number).Create an ER DIAGRAM that shows relationship between eachother and post the picture please . An Inventory entity can be associated with zero or many Beer entities. A Beer entity can be associated with one and only one Inventory entity. An Inventory entity can be associated with zero or one Brewery entity. A Brewery entity can be associated with zero or many Inventory entities. An Employee entity can be associated with one and only one Brewery entity. A Brewery entity can be associated with zero or many Employee entities. An Employee entity can be associated with zero or many Order entities. An Order entity can be associated with one and only one Employee entity. These business rules assume that a brewery company has an inventory of beers, which are brewed by one or more breweries and supplied by one or more suppliers. The breweries employ one or more employees and can receive orders for their beers.Draw the Entity Relationship Diagram (ERD) as explained below. Be sure to show cardinality in both directions using Crows Foot notation. Do NOT include the fields/attributes or keys for each entity The business rules to create the Crow’s Foot ERD are: A department employs many employees, but each employee is employed by only one department. Some employees, known as “rovers,” are not assigned to any department. A division operates many departments, but each department is operated by only one division. An employee may be assigned many projects, and a project may have many employees assigned to it. A project must have at least one employee assigned to it. One of the employees manages each department, and each department is managed by only one employee. One of the employees runs each division, and each division is run by only one employee.
- Draw an ERD that shows the entities, attributes, primary key(s), foreign key(s), and relationships. Each relationship must be labeled. List all identifying relationships (if any). List all non-identifying relationships (if any). List all independent entities (if any). List all dependent entities (if any). Whenever patients are seen for the first time, they complete a patient information form that asks their name, address, phone number, and insurance carrier, all of which are stored in the patient information file. Patients signed up to be seen by doctor must be a member of at least one insurance carrier. Each time a patient visits the doctor, an insurance claim is generated and will later be sent to the carrier for payment. The claim must contain information about the visit, such as date, purpose, and cost. It would be possible for a patient to submit two claims on the same day. The relational notation for the database is: Patient (Patient ID, Name, Address, Phone, Primary Carrier,…Use the ER Dlagram shown on Figure 1 to answer question 9: 9. According to the ER diagram on Figure 1, which of the following is true? A) For each employee, we will keep track of either the employee name or the unique employee ID. B) For each department, we will keep track of either the unique department ID or the department location. C) Each employee reports to exactly one department. A department may have many employees reporting to it, but it does not have to have any. D) None of the above.
