Topic: Database Design - Entity Relationship Modeling (Please answer the below question in 250 words or more). Thank you! It is known that we should avoid redundant data. Let’s say you have a Product Table with the cost of an item, and an Order table that has information about orders from customers. What would be the benefits to also storing the item's cost in the Order table?
You have an application domain that consists of Cities, Towns, and Neighborhoods. A City has a name, zip code, state, and a country. A Town has a name, zip code, state, and country. A Neighborhood has a name, coordinate, and population. Using a relational model, what are Students, Courses, and Sections called? Select one: a. Attributes b. Constraints c. Entities d. Relations
In an ERD, entities do not have columns. Instead which of the following is used to describe the entity's characteristics? Group of answer choices attributes degrees instances relationships
indicate the changes(using the shorthand representation)that you would need to make to the original kimtay pet supplies database design to support the following requierements.there is no relationship beetween customers and seles reps.when a customer places an order. any sale rep can process the order and creat the invoice.on the invoice you need to identify both the customer placing the order and the sales rep responsible for the invoice. draw an e-r diagram for the new design.

REGIONAL LABS CASE QUESTIONS Regional Labs is a company that conducts research and development work on a contract basis for other companies and organizations. Figure 3-32 shows data that Regional Labs collects about projects and the employees assigned to them. This data is stored in a relation (table) named PROJECT: PROJECT (ProjectID, EmployeeName, EmployeeSalary) Assuming that all functional dependencies are apparent in this data, which of the following are true? ProjectID à EmployeeName _______ ProjectID à EmployeeSalary _______ EmployeeName à EmployeeSalary _______ EmployeeSalary à ProjectID _______ EmployeeSalary à (ProjectID, EmployeeName) ______ What is the primary key of PROJECT? ________________________________ Are all the non-key attributes (if any) dependent on the primary key? ____________________________________________…
Which of the following is a key part of conceptual design in an entity relationship model? This model resolves the many-to-many relationships to multiple one-to-many relationships. This model adds all of the attributes for each entity. This model converts attributes into columns. This model does not depend on the database management software or the hardware used to implement the model.
