...I bought a book from crossword; he packed the book and added two bookmarks into my pack. A thought came to my mind. Why do I need a bookmark? I can easily memorize the page number and the next time resume from the same page when I resume reading, or read them all over to reach to the point where I stopped reading. But not all have a blessed memory; moreover, there are better things to remember, my grandpa would rather bookmark and rely on it to help him resume reading. It’s a kind of simple index, isn’t it? This article focuses on how MS SQL Server uses indexes to read and write data. Data is arranged by SQL Server in the form of extents and pages. Each extent is of size 64 KB, having 8 pages of 8KB sizes. An extent may have data from multiple or same table, but each page holds data from a single table only. Logically, data is stored in record sets in the table. We have fields (columns) identifying the type of data contained in each of the record sets. A table is nothing but a collection of record sets; by default, rows are stored in the form of heaps unless a clustered index has been defined on the table, in which case, record sets are sorted and stored on the clustered index. The heaps structure is a simple arrangement where the inserted record is stored in the next available space on the table page. Heaps seem a great option when the motive is simply storing data, but when data retrieval steps in, this option back fires. An index acts as a fire fighter in this scenario. Indexes...

...UNDERSTANDING THE RELATIONAL DATABASES Student’s Name Instructor’s Name Course Name 03/05/2016 RELATIONAL DATABASES Being a data administrator is to handle and organize the bulk of data masses for easy and convenient retrieval of the information at any point of time. I generally believe that compiling a bulk of data is very difficult task for anyone who has the responsibility to manage the information. Therefore, here we go through and understand the concept of relational databases and use of tables designed to manage the data for the problem cases in our daily life. A relational database is a defined group of data items systematized and controlled as a set of formally defined tables from which the collected and unmanageable data can be reassembled or accessed in various different techniques deprived of having to restructure the pre-arranged database tables (Rouse, n.d.). According to Codd (1982), “Relational processing entails treating whole relationships as operands. Its primary purpose is loop-avoidance, an absolute requirement for end users to be productive at all, and a clear productivity booster for application programmers” (p.298). It comprises of designed data tables that are connected together in some important way. For instance, consider an organization that offers items to clients. The organization keeps up a database of the items it offers. Every item has a one of a kind code so it can be uniquely recognized. The item database comprises of a table, and each...

...the perceptions of those behaviors. Think of the study of conflict as a view through a lens, like the lens of a camera, or through prescription glasses. The lens model of conflict specifies that each person has a view of (1) oneself, (2) the other person, and (3) the relationship. These perceptual pieces form the fundamental views of all conflicts, and combined together they form the mosaic of a particular conflict (Wilmot & Hocker 2010). There are also minimal features of all conflicts. They are: (1)the communicative acts or behaviors of each person, (2)the meanings or attributions attached to those acts by each person, which are each person’s view of self and each person’s views of the other, and (3)the meanings or attributions the two people ascribe to their relationship, which include past events, current events, and future projections. Each person also has a lens that gives that person a particular perspective, just as people use different types of glasses to see. There are multiple views of conflict, yet each looks real to the one seeing it (Wilmot & Hocker 2010). In a conflict, each person will have their own view of the situation at hand and react differently. As the old saying says, there are two sides to every story. For example, let’s say you have a couple that gets into an argument or should I say, a conflict, about their child spilling juice on the living room carpet. The mother may view it as being a simple mistake and can easily be cleaned, whereas the father...

...4 Cinematography We are affected and defined by light. Light is the most important tool we have to work with, not only as cinematographers, but as people. —Laszlo Kovacs Courtesy Everett Collection Section 4.1 The “Look” of a Scene CHAPTER 4 Chapter Objectives After reading this chapter, students should: • Have a working knowledge of the cinematographer’s job • Understand the difference between cinematography and mise en scène and recognize the importance of each • Understand the importance of color and lighting and how they affect the tone and feel of a film • Be familiar with different methods of photographing a film, and with terms such as panning, tilting, tracking shots, deep focus, and aspect ratios • Understand how different focal length lenses affect the look of a shot • Recognize what special effects can do for a movie—and what they can’t do 4.1 The “Look” of a Scene W hen we are first introduced to Don Vito Corleone in The Godfather, played by Marlon Brando, the Mafia boss is sitting in the study of his home. Along with his consigliore, or adviser, Tom Hagen (Robert Duvall), Corleone is listening to a line of people requesting favors on the day of his daughter’s wedding. Corleone is immensely powerful, as we learn by the scope of the favors he is asked to grant, which in one case includes the desire of a singer to be cast in a film to revive his musical career, and Corleone’s ability to grant them. However, it is not just what...

...From birth, toddler, child, through adolescence and into adulthood you grow and experience the world. You witness relationships, you catalogue, and you distinguish and start to take a broad view about what you perceive. These experiences, memories and learnt ideas are what form your concept of a worldview. My worldview is that we are all products of our environment. My beliefs and attitudes have resulted from the process through which my education and learning has been obtained. The beliefs and attitudes that I have grown up with, to do with my education and learning, has been because of my parents and how I was raised. My experience of being raised in a military environment, living and travelling all over Australia and overseas, has also very much shaped and broadened my worldview. Every person has a different way of seeing and understanding the world. Hobson (1996) defines a worldview as ‘the primary conceptual framework within which our beliefs, values, attitudes and assumptions about ourselves and others are held’. This interpretation and view can be constructed by many things, parents, close family and the culture, religion and community we live in. So then, a worldview can be personally internal, but be shaped by external manipulations? I relate this to education and learning in the school system where a teacher is the external manipulator who absolutely influences a person’s way of being educated and their learning, and therefore, their worldview. Only some of my educational...

...Merriam-Webster defines worldview as “the way someone thinks about the world”. Scientific and religious cultures have very different worldviews, neither of which can be considered right or wrong. II The Bible says that God created the heavens and the earth and everything on earth. Many people try to discredit this fact by trying to discredit the Bible itself or by stating scientific data. In the book of Genesis alone the word, create is mentioned dozens of times to account for the fact that God was creating us and in what order he created the world. Also in Deuteronomy 4:32 there is a mention of God creating humans and the world. Identity is a key part of the Bible. It gives us understanding that we were talking to God and lets us know our place in the world. 1 Corinthians 12:27 is possibly the on that stands out most to me. That verse alone is strong enough to make an entire crowd stop and think about where they stand in Christ and what their identity is life really is. The Bible also states one that is heard a lot in today’s world because of the abortion conflict. Jeremiah 1:5 is used time and time again by prolife activists to show that abortion is not a way of life. For Christians the meaning of life is one of those questions that are usually better answered by themselves than by nonbelievers. They have an understanding on what their purpose of living on earth actually means. Case in point, Jeremiah 29:11 informs people know that there is a future for them after life...

...An essay about ”This is My Living Room” How much does it take before a man gets enough, enough of turning all of his surroundings into something bad? The narrator gives us an introduction to his life and he expresses life’s negative aspects through this short story. The theme of the story could be “Every man for himself” or “Every man is his own fortune”. These themes are reflected in the text as the narrator says: “People are as mean one place as they are another and they’re always out to get you”. Subsection “People”. “This is My Living Room” is a short story and it’s written by Tom McAfee in 1966. The story takes place in Pine Springs, Minnesota, in a neighborhood characterized by hostility and unreliability. But it highlights as well a family where old traditions are a part of the everyday life. This is reflected in the text when the narrator expresses his opinion about women and their rights. “Women are easier to handle. About the worst they can do is talk and what does that matter”. Subsection “People”. The narrator introduces himself as a smart man and a man that doesn’t believe in anyone but himself. He’s a man in late forties and between the lines; we can perceive him as a male chauvinist. There are likewise examples which describe him as a racist. “Niggers are better than anybody because you can handle them. They don’t hardly ever give you any trouble.” Subsection “People” His two girls Ellen Jean and Martha Kay are sixteen and fourteen years old. They are...

By means of its two star travel products, “Girl Power” and “Grey Lady, RTI has positioned itself as a highly profitable company through a strong word of mouth promotion that is currently attracting large numbers of new clients.

...Before taking apologetics with Liberty University, the term “worldview” was not something I thought applied to my Christian life. This was due to not understanding the true meaning behind the idea. Little did I know, I had already established my worldview. The textbook encyclopedia for this course defines a world view as such, “the framework of beliefs by which a person views the world around him”. As a Christian, when I see this definition, I think of a worldview as what I believe as a Christian and how I choose to define or live my life as a whole. The big questions, “How was the world created?” or “where do we all come from?” are common topics that many people have a specific worldview on. As a Christian, I use the bible as my filter and form my beliefs in this matter based on what scripture says. The very first words of the bible in Genesis 1:1 speak a truth that many scientists and people of the world cannot or simply refuse to comprehend. God create the heavens and the earth. It is such a simple phrase yet it says so much about God and his power. Genesis 2:7 instructs us that man was created from the dust of the earth. Proving we are not revolutionized monkeys, as many would have us believe. Closely tied to the origin of humanity is its identity. As a Christian I value myself as a human because I know I am special. This is so because I, along with all humanity, was created in God’s image, as it is said in Genesis 1:27. I also know my place in this world because...

A detailed view of a person or object, usually without much context provided. Continuity. The kind of logic implied in the association of ideas between edited shots. "Cutting to continuity" emphasizes smooth transitions between shots, in which space and time are unobtrusively condensed. "Classical cutting" emphasizes dramatic or emotional logic between shots rather than one based strictly on considerations of time and space. In "thematic montage" the continuity is based entirely on ideas, irrespective of literal time and space. In some instances, "continuity" refers to the space-time continuum of reality before it is photographed. Crane shot. A shot taken from a special device called a crane, which resembles a huge mechanical arm. The crane carries the camera and cameraman, and can move in virtually any direction. Cross cutting.
