Indirect Set Analysis

• p( ) = Possible

• e( ) = Excluded

Excluded

Possible

Customer = p({<Year={$(=max(Year)-1)}>} Customer)

Returns customers who had an association to last year.

sum(({<Year={$(=max(Year))},

Customer = p({<Year={$(=max(Year)-1)} Customer>}) Sales)

Returns this year’s sales for customers who had sales last year.

Indirect Set Analysis

sum({$<CompanyName = p({$<CategoryName={'Baby Clothes'}>}

CompanyName)>} Sales)

Sales for Customers who purchased Baby Clothes.

The set p({}) returns the values of CompanyName (Customer) that

purchased Baby Clothes.

sum({$<CompanyName = p({$<CategoryName={'Baby Clothes'}>}

CompanyName) - p({$<CategoryName={'SportsWear'}>}

CompanyName)>} Sales)

Sales for Customers who purchased Baby Clothes but not

Sportswear.The first set p({}) returns CompanyName that purchased

Baby Clothes.The second set p({}) returns CompanyName that

Purchased SportsWear.The Unary Operator "-" between the two gives

a list of Customers (CompanyName)that belong to the first but not the

other set.
