Discovering Roll-Up Dependencies


We introduce the problem of discovering functional determinacies that result from “rolling up” data to a higher abstraction level. Such a determinacy is called a Roll-Up Dependency (RUD). An example RUD is: The probability that two files in the same directory have the same file extension, is greater than a specific number. We show the applicability of RUDs… (More)
