A business report that can be created from the DVD Dataset could be a $"$DVD Sales Report". This report would provide an overview of DVD sales, including details such as the title of the DVD$,$ the category it falls under, the rental rate, and the number of times it has been rented$\mathrm{.}1.$ The specific fields that will be included in the detailed table of the report are: Film ID$,$ Title, Category, Rental Rate, and Rental Duration. The summary table will include: Category, Total Rental Rate, and Total Rental Duration$\mathrm{.}2.$ The types of data fields used for the report are: integer $($for Film ID$),$ string $($for Title and Category$),$ decimal $($for Rental Rate$),$ and integer $($for Rental Duration$)\mathrm{.}3.$ The two specific tables from the given dataset that will provide the data necessary for the detailed table section and the summary table section of the report are: the Film table and the Rental table$\mathrm{.}4.$ The Rental Rate field in the detailed table section will require a custom transformation with a user$-$defined function. This is because the Rental Rate is stored as a decimal value, but for the purpose of the report, it would be more useful to display it as a currency value $($e$.$g$.,$ $$4\mathrm{.}99$ instead of $4\mathrm{.}99)\mathrm{.}5.$ The detailed table section of the report can be used by business analysts to understand the performance of individual DVDs$,$ while the summary table section can be used by management to get an overview of the performance of different categories of DVDs$\mathrm{.}6.$ The report should be refreshed daily to remain relevant to stakeholders, as DVD rentals can change on a daily basis.B$.$ Here is an example of a function that could be used to transform the Rental Rate field:SQL CREATE FUNCTION format$\_$currency$($amount DECIMAL$(5,2))$RETURNS VARCHAR$(10)$ ASBEGIN RETURN CONCAT$(\text{'}$$$\text{'},$ FORMAT$($amount$,2))$;END;C$.$ Here is an example of SQL code that could be used to create the detailed and summary tables:SQL CREATE TABLE DetailedTable $($ FilmID INT, Title VARCHAR$(255),$ Category VARCHAR$(255),$ RentalRate DECIMAL$(5,2),$ RentalDuration INT$)$;CREATE TABLE SummaryTable $($ Category VARCHAR$(255),$ TotalRentalRate DECIMAL$(5,2),$ TotalRentalDuration INT$)$;D$.$ Here is an example of a SQL query that could be used to extract the raw data needed for the detailed section of the report:SQL SELECT FilmID, Title, Category, RentalRate, RentalDurationFROM FilmJOIN Rental ON Film.FilmID $=$ Rental.FilmID;E$.$ Here is an example of SQL code that could create a trigger on the detailed table of the report:SQL
