Trent Hardware Database Tables/Fields Refer to the table and field names below for this
database.
1. (15 pts) At Trent Hardware, customers are called buyers. Write a SQL query that lists the top
10 buyers who have spent the most money at Trent Hardware and how much they have spent.
Group the purchases by buyer. Include in the list the buyer's first and last name and the total
dollar amount of the purchases. Order the list from highest amount of total purchases to the
lowest, but limit the list to the top 10 buyers. Code: Results: 2. (15 pts) Write a SQL query to list
the product description and total quantity sold for each product with at least 100 units sold.
(Hint: SQL does not permit the filtering of aggregates using the WHERE keyword. WHERE
filters records before aggregation. HAVING can be used to filter records after aggregation.) List
the product description and total quantity sold (all-time) as "Total\#Sold". (See example output
below.) Sort the list in descending order, thereby showing which product had the highest quantity
sales first. Remove decimals from the "Total\#Sold" by looking up CAST keyword in the
Microsoft SQL Server 2016 online reference and using it in your query. Code: Results:
Section 2: Normalization \& Conceptual Design Part 1 - (30 pts) Decompose an un-normalized
table. Normalize the table below to Boyce-Codd Normal Form the table below. To communicate
your normalized tables/entities, use "sentence structure" (aka, relational notation) similar to the
following: PRODUCT(ProductID, ProductName, etc.) or TITLE (Title id, Title, Pub id).
Underline your indentifier/primary key. (No need to identify foreign keys at this point.) List your
tables in sentence structure here:
Normalization \& Conceptual Design (Continued) Part 2 - (30 pts) Using Visio or LucidChart
and following business rules, create an Entity-Relationship diagram of the tables/entities you
listed above. Business Rules: - An employee can participate in many projects but may not be
assigned to a project. - A project must have at least one employee assigned to it and can have
many employees. - An employee can belong to one and only one department. - A department
must have at least one employee and can have many. NOTE: The diagram must include
relationships with minimum and maximum cardinality. Be sure to use the appropriate
relationship lines (identifying or non-identifying) and appropriate corners (rounded or not) for
entites. Identifiers should be in bold font. Copy and Paste your entity-relationship diagram
below:
Part 3 - (10 pts) Using the tables/entities you created and refering to your diagram, type a SQL
statement below (not using SQL Server) that would return a list of employee name and their
corresponding project name. Be sure to use proper form. Since the tables/entities vou created
have not been developed into a database vet, there will be no output to your code at this time.
Type your SQL Statement below to list the name of the employee and the pr.
