Briefly but precisely explain the difference between single-valued attributes and simple attributes Give an example of each?
A single-valued attribute is one that can have only one value. For example, a person has only one first name and only one social security number. A simple attribute is one that cannot be decomposed into its component pieces. For example, a person's sex is classified as either M or F and there is no reasonable way to decompose M or F. Similarly, a person's first name cannot be decomposed into meaningful components. (In contrast, if a phone number includes the area code, it can be decomposed into the area code and the phone number itself. And a person's name may be decomposed into a first name, an initial, and a last name.) Single-valued attributes are not necessarily simple. For example, an inventory code HWPRIJ23145 may refer to a classification scheme in which HW indicates HardWare, PR indicates Printer, IJ indicates InkJet, and 23145 indicates an inventory control number. Therefore, HWPRIJ23145 may be decomposed into its component parts... even though it is single-valued. To facilitate product tracking, manufacturing serial codes must be single-valued, but they may not be simple. For instance, the product serial number TNP5S2M231109154321 might be decomposed this way: TN = state = Tennessee P5 = plant number 5 S2 = shift 2 M23 = machine 23 11 = month, i.e., November 09 = day 154321 = time on a 24-hour clock, i.e., 15:43:21, or 3:43 p.m. plus 21 seconds
What is the HCF of 315 and 660?
Well, isn't that a happy little question! To find the Highest Common Factor (HCF) of 315 and 660, we look for the largest number that divides evenly into both. First, we can find the factors of each number and then identify the highest one they have in common. It's like finding a common color in two beautiful paintings, bringing them together in harmony.
How Express 840 as the product of prime numbers?
Oh, what a happy little question! Let's break down the number 840 into its prime factors. We start by dividing 840 by the smallest prime number, which is 2. Repeat this process until you cannot divide anymore, and you'll find that 840 can be expressed as 2 x 2 x 2 x 3 x 5 x 7. Just like that, you've decomposed 840 into its prime factors, creating a beautiful mathematical masterpiece!
