Answer: Raw Data
Explanation:
Raw data (sometimes called source data, atomic data or primary data) is data that has not been processed for use.
Explanation:
1
R is many - many;
in this case we have that E1 is not what should be used to determine E2 and in this same way, W2 is not what should determine E1. So non of these can be a key on its own.
2.
R is many-one from E1 to E2
in this case there are 2 tuples (f1,f2) and (e1,e2) which have to be the same if they have the same key attribute for E1. All of them are the same so all the pairs are the same.
3.
R is many-one from E2 to E1:
the explanation for this is is almost the same with that of b. we apply the same logic. since for all keys, all pairs and sets are the same.
4.
R is one-one:
E1 is what determines E2 and likewise, E2 is what determines E1. irrespective of the key that is used, key K is going to the same value of n.
The answer is (B)
print sources consist mostly of text; non-print sources consist mostly of images and sounds.
If we would think in Layman’s, we would describe print sources as ink
and non-print sources as light or electronic. Therefore, print sources are
publications printed on papers and distributed as books, magazines,
newsletters, journals and many more. On the other hand, non-print sources are
mediums that use electronics energy for the end user to access content. Examples
of non-print media include, television, internet, and radio.
<span>Question 1.
Over the last year or so wearable tech has gone mainstream, and the hottest devices on the planet are now ones you can place on your wrists, arms and faces.
Question 2.</span><span>Many people today have a feeling or sense that wearable technology is the future. For professionals who work in the field, it is not just a feeling, it is an obvious truth.
Question 3. </span><span>This was Sergio’s second year at the event and I was attending for the first time. We were both interested to hear about upcoming trends and changes that could affect our industry from leaders in the field. And there was plenty to get our teeth into. The main “track” featured experienced web design speakers and professionals, while a “rising star” segment provided a platform for fresh thoughts and ideas – as well as experts with more controversial views on web design.
Finally question 4. </span><span>If you’re in the same room with someone, there’s certainly nothing faster than just opening your mouth and talking. But in our global economy, many of the people we need to communicate with are in different locations. Technology allows us to easily connect with people worldwide using our choice of forums. We don’t have to wait for a stamped letter to make its way across the miles or rack up a big long-distance phone bill (as was the case not that long ago); instead via the Internet we can instantly reach almost anyone whether through email, instant message, social media, or countless apps. As the speed of communicating has ramped up, costs have been dramatically reduced.</span>
