Title: Title of the book.

Author: Name of the author.

Genre: Genre of the book.

Price: Price of the book.

/*Step 2: Exploring the Dataset*/

/*To understand the structure and contents of our dataset, we can use the PROC CONTENTS procedure:*/

proc contents data=bookstore_sales;

/*Step 3: Data Manipulation Techniques*/

/*Adding New Variables*/

/*Suppose we want to calculate the total revenue for each book and classify the sales performance. We can add two new variables: TotalRevenue and SalesCategory.*/

data bookstore_sales;

    set bookstore_sales;

    TotalRevenue = Price * CopiesSold;

    if CopiesSold > 250 then SalesCategory = 'Best Seller';

    else if CopiesSold between 100 and 250 then SalesCategory = 'Average Seller';

    else SalesCategory = 'Low Seller';

run;

proc print data=bookstore_sales;

run;

Output:

5 5 Sci-Fi Adventures Luke Skywalker Science Fiction 25.00 300 4.8 30JUL2017 7500.0 Best Seller


/*Sorting Data*/

/*To sort the books by TotalRevenue in descending order:*/

proc sort data=bookstore_sales;

    by descending TotalRevenue;

run;

proc print data=bookstore_sales;

run;

Output:

/*Step 4: Aggregating Data*/

/*To analyze the average rating and total copies sold per genre, we can use PROC MEANS:*/

proc means data=bookstore_sales ;

    class Genre;

    var Rating CopiesSold;

    output out=genre_summary mean(Rating)=AvgRating sum(CopiesSold)=TotalCopiesSold;

run;

Output:

/*Step 5: Data Visualization*/

/*Visualizing data can provide insights that are not immediately apparent from tables. SAS offers various procedures for creating plots and charts.*/

/*Bar Chart of Total Revenue by Genre*/

proc sgplot data=bookstore_sales;

    vbar Genre / response=TotalRevenue stat=sum;

    title "Total Revenue by Genre";

run;


/*Scatter Plot of Rating vs. Price*/

proc sgplot data=bookstore_sales;

    scatter x=Price y=Rating / datalabel=Title;

    title "Customer Rating vs. Book Price";

run;


/*Step 6: Advanced Data Techniques*/

/*Merging Datasets*/

/*If we have another dataset containing information about the publishers, we can merge it with our bookstore_sales dataset.*/

/*Assuming we have a dataset publishers:*/

data publishers;

    input PublisherID PublisherName $;

    datalines;

1 "Tech Books Publishing"

2 "Culinary Press"

3 "Mystery House"

4 "Historical Publications"
