JOBSEEKER?

A grocery shop is using the following tables in their relational database:

TABLE Product 
  id INTEGER
  name VARCHAR
  categoryId INTEGER REFERENCES ProductCategory(id)

TABLE ProductCategory 
  id INTEGER
  name VARCHAR

TABLE ProductSale
  id INTEGER
  productId INTEGER REFERENCES Product(id)
  price DECIMAL
  date DATE

ProductCategoryDimension(categoryId, categoryName)
ProductSalesFact(productId, date, price)
ProductDimension(productId, categoryId, productName)
TimeDimension(dateId, productId, month, quarter, year, date)
