Explain The Following.

How would you explain the following photo?

Well, everyone has a different eye, and that's the reason art is so vast. I do not know what you exactly want to know when you ask for explanation. The photo looks like some screenshot from some movie. But if we see it as a photo, by forgetting the story behind it from the movie, here is what I can see and guess at first by just observing the photograph: A cup of coffee, on a table, that's probably a restaurant or maybe just someone is enjoying a cup sitting at home. The cup appears somewhat empty, as I guessed it from the coffee foam there, so someone has been sitting quite a while enjoying the coffee. Some person appears to be standing behind, maybe there was some chit chat that goes along with the coffee. If you notice the stance of that hand, it looks like that person is just playing with the cup, maybe moving it around in the saucer in circular manner because maybe he is bored. The role of person standing behind remains unknown. The person is difficult to guess whether a man or women. I assume a women from the body posture. She maybe just a waitress, if we assume the place is a restaurant. The bluish tint n the photo expresses the mood of mystery and horror. The scene moreover looks like from a serious situation in the movie.To me, this photo conveys mixed expressions. It kind of express the bored-ness. That person with the coffee mug looks bored and hence playing with the cup, whereas another story could be that he might be waiting for someone over a cup of coffee. The lady standing in the background gives a feeling of mystery to me. Her face is not shown, what she is doing there is difficult to guess and hence her role in the photo remains a mystery.From the photography point of view, the placement of cup and the hand looks quite proper. The cup somewhat appears to be on rule of thirds grid. But the person standing in the background distracts viewer's eye. The background had to be clean for this photograph. And I feel the bluish tint in the photo expresses the mood of mystery and horrorWell this was my view. It might or completely differ form your thoughts, or from the scene in the movie from where you captured it.Do check my work at Pankaj Dhande's Kingdom

How will someone explain the following SQL?

Think of the analogy of a telephone book. The book is ordered by last name then by first name. If you want to look up someone by their last name, it's very quick. Once you find a person by last name then by first name, you get their phone number and perhaps address.But what if you want to look up someone by their first name? The order of the book doesn't help you find everyone named "Bill". You would need a second book, ordered in the other manner, by first name first. To save space, this book might not print the other attributes for that person (phone number and address), it might just have the person's last name. Once you have the last name and the first name, you can use that to look up the person in the primary phone book. The second, abridged phone book is analogous to a secondary index. It's a copy of all the entries in a secondary attribute (i.e. not the leftmost column in the primary key), sorted, then including what you need to find the primary key in the clustered index.You could also create additional telephone books on other attributes, for example on the person's address, so you could do quick searches to find who lives at a given address and their phone number. That would be pretty powerful! The information is already in the primary phone book, the only reason why people aren't able to do that is because it would be too time-consuming to search the entire phone book for a specific address. But if it you had another sorted book by address, it would be easy.In MySQL syntax, the keywords KEY and INDEX are more or less synonyms (they can't be used interchangeably in every statement, but they refer to the same database object).KEY `last_activity_idx` (`last_activity`)
This syntax means the table automatically maintains a secondary index for the last_activity column. The index has a name which is last_activity_idx. The name is useful if you want to drop the index or if you want to name it in an optimizer hint.
