7. In the context of database design, consider the following scenario: There is database table that contains columns for employee ID, employee name, department, department location, and project details. Upon analyzing the table, you notice that there are multiple rows with the same employee name, department, and department location, but different project details. Based on this scenario, which of the following best describes the normalization process that should be applied to improve the database design? A) Split the table into two: one containing employee ID and employee name, and the other containing department, department location, and project details. B) Combine all columns into a single table to reduce redundancy. C) Normalize the database to the third normal form by creating separate tables for employee details, department details, and project details, and establish relationships between them. D) No action is required as the table already follows the normalization principles.

1.Indicate the changes (using the shorthand representation) that you would need to make to the original KimTay Pet Supplies database design (see Figure 2-1) to support the following requirements. A customer is not necessarily represented by a single sales rep, but they can be represented by several sales reps. When a customer places an order, the sales rep who gets the commission on the invoice must be in the collection of sales reps who represent the customer. 2.

A data model is a collection of data description constructs. The main purpose of a data modeling is to assist in the understanding of the meaning (semantics) of the data and facilitate communication about the information requirements. Discuss FIVE (5) evaluation criteria for a good data model.

You will need to create the database tables and choose sensible data types for each column.Make sure to maintain entity and referential integrity, and implement all the above constraints.Since other developers work in parallel on other parts of the system, you will need to strictly follow the above specification to correctly implemented in your database. Otherwise, the other software will not be able to use your database. This means, one needs to be able to rely on all constraints being correct, the spelling of table and column names being as given, and that the data types that you chose will allow for sensible data to be added to the database in the future.For testing purposes, you are asked to insert the data specified below into the tables, but no other data except this.In short:1. You will need to create the tables as specified2. You will need to add the data specified Please use the 3.sql and implement your tables using the sketched CREATE TABLE commands. Add the necessary queries…
Consider the following business rule:An employee can manage multiple customers. A customer can be managed by multiple employees. How does this business rule(s) affect the database design? a.) The business rules define that there isn't a need for a relationship between the EMPLOYEE and CUSTOMER entities, as the relationship isn't a strong one. b.) The business rules define that there is a relationship between EMPLOYEE and CUSTOMER, and a 1:M relationship between those two entities. c.) The business rules define that there is a relationship between EMPLOYEE and CUSTOMER, and an M:N relationship between those two entities requiring a bridge table. d.) The business rules define that there is a relationship between EMPLOYEE and CUSTOMER, and a 1:1 relationship between those two entities.

The attached EERD is not the answer. it's for your reference only about UML Modelling Notation. -Based on the information given below, draw the conceptual EERD where you should include the enhanced features. A car dealership wishes to maintain data about the customers who purchase a car. Each customer may purchase one or more vehicles and each vehicle can be purchased by many different customers over time (for example, a customer maypurchase a new vehicle, trade that vehicle in and someone else can purchase the vehicle traded in.) Data that the dealership wishes to keep regarding customers includes customer identification number, name, address, homephone, work phone, cell phone and e-mail address. Information about vehicle includes vehicle identification number, make, model, year, transmission type, engine size and color. Vehicles can be a member of one of the following…
