SELECT Founder, AVG(Manufacturer) FROM Products AS T1 JOIN Manufacturers AS T2 ON T1.Manufacturer = T2.Code GROUP BY Founder ORDER BY AVG(Manufacturer)
For those records from the products and each product's manufacturer, give me the comparison about the average of manufacturer over the founder , and group by attribute founder, and I want to sort by the total number in asc.
CREATE TABLE Manufacturers (
    Code INTEGER,
    Name VARCHAR(255),
    Headquarter VARCHAR(255),
    Founder VARCHAR(255),
    Revenue REAL
)

CREATE TABLE Products (
    Code INTEGER,
    Name VARCHAR(255),
    Price DECIMAL,
    Manufacturer INTEGER
)
