...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...

...Aristotle As an important figure head in the field of philosophy, Aristotle and his numerous influences will be detailed. Identification and evaluation of key concepts and analyses that comprised his theories will be discussed along with identification and description of his contributions to the field of philosophy will also be offered. Lastly, further discussion will focus on how the culture and the time period influenced his ideology. Metaphysics Metaphysics is a branch philosophy concerned with explaining the fundamental nature of being. It is considered to be one of the greatest philosophical works. It kind of piggy backs off of Plato’s theory of forms. Plato believed that the nature of things is eternal and doesn’t change, but we know from just living in this world that things are always changing daily. Aristotle wanted to reconcile these contradictory statements of the views of the world. Aristotle used the influence of both Heraclitus and Parmenides. One believed that things appear to be permanent but they are really gradually changing all the time. Parmenides, argued certain conclusions could be reached by using reason alone and making no use of senses. After studying at the Academy, Aristotle would turn against his teaching and felt that there was a connection between the abstraction of existence and the science of nature. Aristotle described substance as material reality and formal and discusses the connection between actuality and potentiality. According to...

...Why in the School of Athens does Plato point upwards and Aristotle point forwards? The School of Athens is one of the most famous murals by the artist Raphael which was painted during 1509 and 1510. In the middle of the painting you can distinctively see two men, one of who is pointing upwards to the heavens and one who is pointing straight forward. These two men are the famous Plato and Aristotle. Plato thought of the theory of forms which is the idea that everything has a true form and the telos of life is to try and get our souls back to the world of true forms. Aristotle however, believed more in the materialistic beings of things, the material cause. Aristotle was taught by Plato at the school of Athens, although he did not have the same views, he always took what Plato believed into consideration and recognised the value of what he had learnt from Plato and in many of his books refers to the ideas given by Plato. So why in the photo is Plato pointing upwards and Aristotle pointing forwards? the answer is simple, it is trying to present the different views of both men subliminally so even if we don't know anything about them, we will have a brief idea of what they believed in. For example, Plato is pointing upwards because he believed in the World of Forms and trying to get our souls back to the place they come from in that world, however Aristotle is a firm believer in the Materialistic world therefore he is pointing...

...My review is going to assume the perspective of Aristotle: Choose one of these thinkers, and based on the assigned readings from his work and your understanding of his view of stories and storytelling, explain what he might think of Boccaccio’s work. The review should contain a very brief summary that identifies and discusses the main idea(s) of both The Decameron and the text by your chosen critic Followed by a critique of The Decameron’s strengths and weaknesses in the voice of your chosen critic. Platos views on storytelling- He opens by characterizing the effect of poetry [and storytelling] as a 'crippling of the mind'. It is a kind of a disease, for which one has to acquire an antidote. The antidote must consist of a knowledge 'of what things really are'. In short, poetry is a sort of mental poison, and is the enemy of truth. This is surely a shocker to the sensibilities of any modern reader and his incredulity is not lessened by the peroration with which, a good many pages later, Plato winds up his argument Plato thought ethics was an exact (theoretical) science; Aristotle thought precision was extremely difficult in a science such as ethics. Please note that "science" is being used in its ancient sense of knowledge in general. Aristotles views on storytelling- Art does not attempt to teach. It merely asserts it is thus or thus that life is perceived to be. That is my bit of reality, says the artist. Take it or leave it – draw any lessons you like from it – that...

...“wisdom” respectively) have been preoccupied with the investigation of the reasons for human existence and the way men should live, so as to be consistent with their reason for being. Their views widely appealed to the western world and formed the foundation for western philosophy and psychology, influencing the philosophers who followed, from the oldest to the most contemporary ones and inspiring passionate support but not without also being questioned. Today, most of their views seem to have lost nothing of their lustre and stand out like shining beacons, especially now that the western world is desperately seeking answers in order to relight its fires!!! In the text below, I refer to Aristotle and Socrates, the principles and practices they bequeathed us, so as to prove that these have a lot in common with the principles and practices of coaching. In addition, I will attempt to prove that Socrates is the first ever coach!!! Aristotle, a student of Socrates and Plato, the most important philosopher according to some and teacher of Great Alexander, clearly stated why and how men should live. According to Aristotle we should pursue happiness, well-being or in other words eudaimonia. And a happy life is a life full of virtue! • A coach urges us to lead a happy life. According to Aristotle, true happiness is permanent and timeless; it is achieved when people develop and leverage...

...writers from Paper Masters have researched and found that Aristotle takes much of his notion on friendship from politics. Research papers on Aristotle's view of friendship looks at the philosophy of Aristotle and explicates how this philosophy boils down to politics and virtue in a man. Aristotle's treatment of friendship, including his definitions of friendship, is found within his work on ethics, the "Nicomachean Ethics." Friendship is included within his discussion of his general ethical theory. Aristotle bases his ethical theory on two constructs: Politics Virtue In most of the "Nicomachean Ethics," Aristotle discusses these two major subjects as separate subjects; or when they are discussed in relation to each other, they are discussed mostly with respect to what proportion of each is found in political activities or the conditions or state of a person's life. For instance, the more political an action is, the less virtuous it may be. And the more virtuous is an individual, the less he may be involved in the practical ends of politics. As mentioned earlier, friendship is a blending of politics and virtue; it can be looked at as an ideal blending. The Philosophy of Friendship According to Aristotle Friendship is included as a subject in term papers about Aristotle as a part of his general ethical theory because friendship has to do with the good which is the fundamental of the general ethical theory. As Aristotle begins the "Nicomachean Ethics," "Every art and every...

...Critically compare Aristotle’s and Richard Dawkins’ views on body and soul identity. (35) The mind-body problem is an ongoing problem in the philosophy concerning the nature of the relationship between the mind, or consciousness, and the physical world. It questions how our mental thoughts are linked to our physical activities. In religion and philosophy, the soul is considered the immaterial aspect or essence of a human being, which is often considered to be synonymous with the mind or the self. In theology, the soul is further defined as that part of the individual which is thought to survive the death of the body. However, this view point isn’t taken by all. Viewpoints on the soul can be separated into monism, dualism and materialistic views. Aristotle is a monist believing that the body and soul are not linked, whereas Dawkins is a hard materialist believing that biology is the key. Aristotle defined the soul, or psyche, as the ‘first actuality’ of the body and argued against it having a separate existence from the physical body, unlike other philosophers such as Plato. Aristotle’s belief was that the difference between a live body and a corpse is the presence of the soul. When the soul dies, so does the body. In his book, De Anima he stated that “the soul does not exist without a body and yet is not itself a kind of body. For it is not a body, but something which belongs to a body.” In Aristotle’s view, full actualisation of a living thing is its soul. The soul...

...cognition comes from the appearance of the world not the reality. According to Plato, there exist two worlds: the real world and a supernatural realm which contains the eternal and perfect Forms. Everything we get from the real world is a reflection of the supernatural hence the essence is invisible. Reason is the only way in which we get the essence of appearance. Based on Plato’s metaphysics, Parmenides and Heraclites assert diverse opinions. Parmenides assumes that being is real and change is the characteristic of being while Heraclites considers change is real while being is not. Plato also holds the view that human beings are born with knowledge, and the immortal soul belongs to the supernatural. That we use our reasoning capacities to recover from the knowledge known before is called learning-by-recollection. On the other hand, there exists empiricism, represented by Aristotle who states that the source of knowledge is not reason but sensory experience. He disagrees with Plato’s two-worlds theory. For him, there is only one world--the natural world and no higher or transcendent world exist. Hence, we are able to have access to it through the use of senses. All these knowledge derives from sensory information so we are in-formed by them. He also insists that essence is part of the real world. Therefore, it is accessible by empirical researches, not merely by using...

...Ethics in Aristotle’s Philosophy Ruth Geter AC 504 Ethical Issues in Business and Accounting Unit 2 Assignment July 19, 2016 Aristotle Philosophy Introduction I have chosen Aristotle as my philosopher. “He was the first to argue that equals should be treated equally, and unequal’s should be treated unequally in proportion to their relevant differences” (Brooks and Dunn, 2014). In today’s society people sometimes lose sight of being ethical and often know what is right but chooses to not do the right thing. Most of the time it is out of greed or selfish reasons. His ethical theory is about being happy. “Of all the classical theories considered here, his is the farthest from an ethics of self-interest” (P.I.E,2006). Included in this paper will be philosophy, history of Aristotle, his theories, ethical practices in accounting and business in general and the connection between me and Aristotle. Philosophy “Philosophy is the fundamental study of ideas about knowledge, truth, reality, and the meaning of life” (free dictionary, 2015). According to the dictionary a philosopher is someone who offers theories or opinions in relation to profound questions in terms of ethics, logic, metaphysics, and other related fields” (free dictionary, 2015). Ethics help society in everyday situation whether personal or business related. Ethics help guide us to solutions where the answer is not right or wrong. It is important to weigh the decision based on who may benefit from the outcome...

...ARISTOTLE Aristotle was born in Stagira, a “Grecian colony. His father was a court physician to the King Amyntas of Macedonia. It is believed that his purse of studies is due to his father’s influence of practicing medicine. He died at his country house at Chalcis, in Euboea at the age of sixty-two years old in the year of 322 B.C. He died to an illness he suffered from for a long period of time. There were legends that told his death to be because of hemlock poisoning, as well as another legend, it was said he couldn’t explain the tides so he threw himself into the sea. Aristotle was a high-minded, kind hearted man devoted to his family and his friends. He was a man who followed the ideals he outlined in his ethical treaties (“Aristotle”). During the time frame of thirteen years when Aristotle taught at his school, called Lyceum, he composed his writings into dialogues (“Aristotle”). His school was widely known as the walking school or the Peripatetic school because a lot of the discussion at the school took place while walking the grounds (“Encarta: Aristotle”). He taught the young conqueror Alexander, who became Alexander the Great, and thereafter his writings were lost and not recovered until the 1st century B.C. During the middle ages they were translated into Latin and Arabic and became a basis for Christian theology. In 2000 years no one has came close to his brilliance...

...What is politics? For centuries humans have argued constantly about everything. There is always someone who disagrees with another human’s point of view. When discussing politics there are numerous questions that require answers. What will be discussed in this essay is the question many people have longed to have an answer for. What is politics? By regurgitating Aristotle and Thomas Hobbes in this essay, we will get to define politics. Aristotle believes that man is naturally geared towards the well being of a community whereas Thomas Hobbes believes the exact opposite. Hobbes believes that humans are individually minded and only focus on themselves. By elucidating both point of views we will then be able to decide for ourselves which one of these authors seems to be more right in defining what is politics. While reading Aristotle’s book Politics Aristotle firmly asserts that the city-state exists by nature. He writes: A complete community constituted out of several villages, once it reaches the limit of total self-sufficiency, practically speaking, is a city-state. It comes to be for the sake of living, but it remains in existence for the sake of living well. That is why every city-state exists by nature since the first communities do. (Page 3 Lines 26-30). Once a community fully becomes independent and does not require any outside help in satisfying their needs that is when a community becomes a city-state. Here we see Aristotle’s assertion that a “city-state exists by...

Aristotle will be described through his learning during the most critical years including his key concepts and style of philosophy during the period in which he resided and his key influences through his lifespan and the effects that he has on society today. Bright Future In 384 BC Aristotle was born in a small town called Stageira, Chalcidice around the fourth century in northern Greece. Aristotle was born to Nicomachus who was a very well know physician in his era. Aristotle’s father Nicomachus personally attended to King Amyntas of Macedon. During this time Aristotle became suited to be trained and educated like a member of Aristocracy through the will of his father due to their stature in the society, being they were middle class individuals.
