Association Rules. In Association Rules, we look at the associations between different items to draw conclusions from.In sales, we look at purchases:Example in bookSomeone who buys bread is most likely buy milkSomeone who buys the book Database System Concepts is quite likely also to buy the book Operating System Concepts..
