Include all necessary Primary Key and Foreign Key constraints. This should be syntactically correct to test in a MySQL database.

Create an ERD for a car dealership and also show entity names, primary keys, attributes for each entity, relationships between the entities and cardinality. The dealership sells both new and used cars, and it operates a service facility. Base your design on the following business rules: A salesperson may sell many cars, but each car is sold by only one salesperson. A customer may buy many cars, but each car is bought by only one customer. A salesperson writes a single invoice for each car he or she sells. A customer gets an invoice for each car he or she buys. A customer may come in just to have his or her car serviced; that is, a customer need not buy a car to be classified as a customer. When a customer takes one or more cars in for repair or service, one service ticket is written for each car. The car dealership maintains a service history for each of the cars serviced. The service  records are referenced by the car’s serial number. A car brought in for service can be worked on by…

Please Help!!! Create ERDs for the following cases. • Identify entities, identifier and attributes for each entity, and relationships between the entities. Identifiers can be represented as either PK or underline. Define cardinalities of each relationship. • In this assignment, you don't need to define an associative entity (optional). Let me clarify that while a many-to-many relationship should be converted to an associative entity for the next step (logical data modeling), this assignment for conceptual data modeling allows you to either leave it as many-to-many or use an associative entity for it. If needed, you can make some reasonable assumptions on attributes and cardinalities of relationship. Problem 1 Create an ERD based on the following business rules for course enrollment. • Each course can have multiple sections. Multiple courses cannot be taught in the same section. • Each section is assigned to one instructor. • Each instructor can teach zero, one, or many sections of…

PLZ help with the following: Create a Crow’s Foot ERD. Draw YOUR entity relationship diagram (ERD) to indicate entities, relationships, connectives, and resolve M:N relationships. For the following: The faculty and students (we refer to them in our system as clients) can electronically check out any book at any time. A book must have at least one author but can have more authors. An author must have written at least one book or more to be included in the system. A book may have neverbeen checked out, but can be checked out many times by the same client or different clients over time. A client may have never checked out a book or they may have checked out many books over time. To simplify determining which client currently has a given book checked out, a M:N relationship between BOOK and CLIENT should be maintained. The information recorded for each book is book number, book title, book subject, and year of publication.   For each author, the library records the author ID,…

Was cardinality ever used as a representation of anything in an entity-relationship diagram? 1:The unique identifier that is used to store data 2:The maximum number of entity instances that may be used in a connection 3:The total number of primary keys associated with an object. 4:The total number of attributes possessed by an entity

Draw and ERD digrame for my home work . Below are the standers that should be meet 1) Correct identification of all the entities. Entity names should follow the standard conventions, i.e., they should be singular nouns and written in CAPITAL letters, or at least the first letter is CAPITAL. 2) Correct identification of all the attributes for each of the entities .Correct identification of all the relationships with appropriate connectivity and participation. If the connectivity and/or participation are not clear from the assignment specification, the assumptions made should be clearly stated.3) Introduction of composite/bridging entity to represent many-to-many relationships. 4) Correct representation of strong and weak relationships (solid and dashed line) 5) Correct identification of all the primary keys and foreign keys. The primary keys should be underlined, and foreign keys should be italic.
