Design an Entity-Relationship diagram for the below environment. determine 1-Total participation.2-Partial participation Consider a MAIL_ORDER database in which employees take orders for parts from customers. The data requirements are summarized as follows: o The mail order company has employees, each identified by a unique employee number, first and last name, and Zip Code. o Each customer of the company is identified by a unique customer num, first and last name, and Zip Code. o Each part is identified by a unique part number, a part name, price, and quantity. o Each order placed by a customer is taken by an employee and is given a unique order number. Each order contains specified quantities of one or more parts. Each order has a date of receipt as well as an expected ship date. The actual ship date is also recorded.

A well-structured database starts from an effective Entity Relationship Diagram (ERD). For this part of the question, you will need to sketch an ERD for the following gym scenario: A member must have a member ID, name and contact number, can be enrolled in one or more gym session. A gym session can be enrolled in by one or more members. Each gym session is identified by a session ID, and has a name, date and instructor details (Instructor ID). An instructor has an instructor ID, name and contact number, and must only be assigned to one gym session. A gym session can have one or more instructors assigned in it.” *show entities, relationship types and cardinalities. Crow’s foot model notations recommended.
Please written by computer source Part I - Modeling You are building a database for a comic book store customer management system. Given the database specification below, your job is to turn the specification into an ER diagram. Your notation must be consistent with the notation used in our lecture notes. You can use all constructs and notations discussed in our lecture notes and nothing else (i.e.. oven notations used in the textbooks but not in our lectures cannot be used). Your ER diagram should capture all the information and constraints in the specification but, at the same time, be minimal. It means that redundant entities, relationships, attributes and constraints should be avoided. You may use any drawing tool of your choice (for example, Dia, diagrams.net, Lucidchart, etc.) to draw your ER diagram. Hand drawings will not be accepted. Database Specification The database keeps information about comic books, customers, orders, inventory and reviews. First, the database should…

Draw ER (or EER) diagram: A conceptual database design for a chain of furniture stores is needed. The following is a summary of the database requirements: a) The chain has many different stores in various cities and states. Each STORE has unique StoreNumber, plus an Address(made up of Street, City, State, ZipCode), and a StoreManager (who is an employee). Each store is organized into a number of departments. b) Each DEPARTMENT contains certain types of furniture (such as ‘dining’, ‘living room’, ‘bedroom’, ‘office’, etc.), and has a DeptName that is unique within each store; it also has a DeptManager (who is an employee), and a number of SalesPersons (who are employees). c) The company employs many employees. Each EMPLOYEE has a unique SSN, plus a Name (made up of FirstName, Minit, LastName), a job (e.g. ‘store manager’, ‘dept manager’, ‘sales associate’, ‘sales person’, etc.), plus DateOfBirth, Sex, Salary, and CommissionRate. Each employee works for a particular store. Design an ER…

ER Modeling 3. You will prepare an ER diagram describing the schema of a University database. High Achievers University (HAU) would like you to design a database that tracks its adminis- trative operations, and helps them monitor their energy usage across campus. HAU consists of departments, research groups, and employees. For each department, the database should record the department name, and the department's unique identifier. Research groups belong to exactly one department, and the database stores the research group ID, name, and its monthly budget. Each research group has to have at least one employee working in it, and is assigned at most one room as workspace. For each employee, the University assigns a unique employee ID, and records the employee's last name, first name, telephone number, address, salary, gender, data of birth, and his/her years of service. An employee may work in zero or more research groups. An employee may be a department chair. If so, they can be the chair…
Prepare an entity-relationship diagram for the database in a following company: Holiday Travel Vehicles sells new recreational vehicles and travel trailers. When new vehicle arrives at Holiday Travel Vehicles, a new vehicle record is created. Included in a new vehicle record are a vehicle serial number, name, model, year, manufacturer, and base cost.
