...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...

...Immigration is the arrival of new individuals into a new environment or population. Immigration is a process that happens every day, but there is a side effect of immigration that is observed between the parents (first generation) and their children (second generation). In history, during the nineteenth century, Chinese travel to America for financial solutions, with hopes to return to their home with money. As time moves ahead, Chinese immigrants to America searching for a better life, for instance, my parents immigrated to America, who then conceived us as the second generation. With pressure from the parents, children of the second generation were forced to perfect both the American and Chinese culture to their very best. The second generation Chinese Americans were American born, but were still outcasts of the American society because of their skin color. The lives of the children of immigrants who immigrated to America have had stressful impacts from their parents and society because of their parent’s expectations of a perfect child who succeeds in school, and the society’s rejection of their ethnicity. From the old days until now, millions of people around the world have decided to immigrate to the United States in search of a better life. The reason why Chinese people immigrated to America due to the rumors of opportunity to gain higher wages jobs within America which would help support their families who were struggling to survive in China. According to Hubert Howe Bancroft...

...important point that, perhaps her generation is the last to truly know the meaning behind the word “home”. The contributing factors to such conclusion derived from her personal experiences with her direct family (mother, father, and brother), her husband, and even her own daughter. Didion first sets her definition of home by clarifying that to her, home means “not where [her] husband and [she] and the baby live, but the place where [her] family is.” (Didion1) Her diction reflects the way she thinks about her home, with words such as “troublesome” that give off a negative connotation. Although she defines this place as her home, she expresses how she changes personalities and formalities in front of her parents and brother, which her husband is unfamiliar with. This transformation represents her familiarity with her family, whom she grew up with, or her childhood. However, since she is not in her childhood anymore, this familiarity is somewhat uncomfortable to her and her husband, whom Didion is more accustomed with. She, therefore, calls her “home” a “burden” (Didion2) where her source of tension and drama come from. Didion’s relationship with her husband reflects what she left behind at “home”. When Didion visits her family with her husband, she returns to her ‘old self’ whom her husband sees as “difficult, oblique, deliberate, [and] deliberately inarticulate” (Didion1) merely because he is not used to it and is unfamiliar with it. Her husband’s views on her family’s talks and mementos...

...The Most Expensive Home The door thuds as you close it behind you on your way out to go to school, work, or wherever you are headed. You don’t have a second thought about what you’re leaving behind: your home. But have you ever thought about the significance of that word, “home”? In Joan Didion’s essay, “On Going Home”, Didion describes her experiences and thoughts on what defines her meaning of home. Didion uses many asyndetons and polysyndetons to emphasize her emotions and poses several rhetorical questions. Throughout the essay, it can be concluded that perhaps the generation that truly knows the meaning behind the word “home” is gradually disappearing. The contributing factors to such interpretation derived from Didion’s personal experiences with her direct family, her husband, and even her own daughter. Didion first sets her definition of home by clarifying that to her, home means “not where [her] husband and [she] and the baby live, but the place where [her] family is”. Her diction reflects the way she thinks about her home, with words such as “troublesome” that give off a negative connotation. Although she defines this place as her home, she expresses how she changes personalities and formalities in front of her parents and brother, which her husband is unfamiliar with. This transformation represents her familiarity with her family, whom she grew up with, or her childhood, and a vague description of what makes up her home. However, since she is not in her childhood...

...However, by changing how people view and practice teleology, nature culture dichotomy, worldview, culture, and sense of place then these concepts can be used to help solve human-environmental problems. Even though all of these concepts can be connected on a cultural level, they can be broken apart on an individual level. For example, not everyone believes in nature culture dichotomy, for that is a Western thought, also people may have a different sense of place from each other due to where they have been and who they have experienced that place with. When it comes to teleology, there are some people who view nature and see the purpose for a tree is to grow and be able to provide food, shelter, oxygen, and to just live. A tree can already have many purposes, some that even benefit humanity, without the need to cut down the tree to be made into paper or other consumer products. We cannot make the assumption that nature and place has the same meaning for everyone. I do hope that at some point, despite the fact that everyone does view nature in a different way, that we are able to make environmental improvements to better the...

Having an opinion or position towards a culture and worldview is part of human nature (Ministry of Justice, 2001). As we develop, these views and positions we thought we were once in, can change and alter. In other words, as people adapt and learn, so too does their views (Houhamau, & Sibley, 2014). In this essay I will be describing my worldview and cultural positioning of when I was growing up and contrasting this to how I feel now. I will also discuss this in relation to things Māori and who changed or influenced these views. I will finally critically analyse my relationship of tangata whenua. My mihimihi does not just describe who I am and here I come from. It describes my identity, my own conception and expression of myself and my affiliations both culturally and physically. My mihimihi establishes the links I share and have. As a Māori, sharing my whakapapa it is about knowing yourself and knowing one’s identity (Korero Maori, n.d.). By knowing my identity it shows the links to where my cultural positioning and worldview might stand (Ministry of Justice, 2001:...

...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...

They responded to the trends by taking the idea of a traditional classroom to establish the Integrad buildings. Now that the trainees play video games that simulates mock village delivery as well as the slip and fall. These are the types of processes we will have to change as we go through generations and a fast changing global environment 2) Why is efficiency and safety so important to UPS? What role do the company’s industrial engineers play in how employees do their work? Efficiency means saving time and lowers expenses as well. As for safety, which they must take of importance otherwise they would have to consult with labor union. At the end of the day, UPS just wants the employees to have their tasks and deliveries done in a set amount of time to be as efficient as possible. 3) What changes did the company make to its driver training program? What do you think of these changes? Significant changes and if you think about it, was a low risk. UPS basically wanted to get with the times and go along with the generation we now live in. The driving simulator identifies obstacles for them to overcome, and the slip and fall simulator. My personal opinion is that it saved a bunch of time and money. It saved time by having a higher percent of graduates of the program and not having to start the process over...
