Please do not copy and paste from the assigned paper. 1. Clear statements of the problem(s) (or issue(s)) that the paper is addressing (upto 2 pages only): The most efficient database systems performance depends mostly on index tuning. Index tuning is defined as a process of creating and utilizing the best indices according to the workload. But, the difficulty of this process has been increased so radically in the past few†¦show more content†¦Especially the patterns used for query processing follow an experimental behavior, which changes so randomly that it cannot be anticipated. So, these type of environments cannot be handled by offline indexing. Online indexing and adaptive indexing are two approaches for designing a physical design automatically in such dynamic and exploratory environments, but none of them handles the problem adequately when isolated. 2. Clear statements of the solution(s) of the paper (up to 2 pages only): The paper discusses about the problems faced when using the index tuning and a solution is implemented to improve the performance of the database system called the holistic indexing, a novel approach which automates the process of index tuning in dynamic environments. It requires zero set-up and tuning effort, depending on the adaptive index creation as a side-effect of processing the queries. The creation of Indices is done incrementally and partially. These created indices are refined constantly as more and more queries are processed. The proposed holistic indexing takes the state of-the-art adaptive indexing concepts a big step further by introducing the idea of a system which refines the index space continuously and never stops while taking educated decisions about which index to be incrementally refined next based on continuous knowledge acquirement about the running workload andShow MoreRelatedEDPM CSEC15093 Words   |  61 Pageswithin the work environment.

With heavy and unjustifiable fishing techniques the fishing populations has been declining over the years. As of this moment close to eighty-five percent of the world’s fisheries have been threatened. With the lowering fish populations, the world has had to adjust by reducing the amount of fish that are harvested. But still the fish population is on the decline. Due to the over fishing of certain species, mostly predators (sharks, tuna, etc.) has had a negative effect on marine ecosystems. Overfishing also leads to bycatch; catching of unwanted fish, which leads to millions of dead fish each year. Overfishing also having a negative effect on the economies of fish communities too. Fishing communities that solely rely on fish harvesting and fish consummation are faces overwhelming affects. Developing countries were they account for almost fifty percent of the world’s fish export, and being hit the hardest with these consequences. The overfishing by the world†™s fleet leads to illegal fishing and higher prices for the developing countries. Fish is one of the most important sources of for that this world offers us, and over seventy-one percent of the world is ocean water. Fish is a huge source of protein for humans; in Asia almost one billion people’s primary source of protein comes from fish. Almost twenty-five percent of the world’s consumed animal protein is provide threw fish, twenty percent from the ocean and five percent from fish farms. Even though the fishing

Macbeth suggests that great ambition, or inordinate lust for power, ultimately brings ruin free essay sample

William Shakespeare’s ‘Macbeth’ is a play, which tells the story of Macbeth’s rise to power and subsequently his tragic downfall as a result of outside forces and his great ambition, or his excessive use of power. While the play centralizes around the ideas of ambition and power there are also other outside forces and elements, which greatly influenced Macbeth’s decisions and ultimately lead to his ruin. The main root of Macbeth’s ruin was his uncontrollable ambition and how his inordinate lust for power blinded him and took over his former traits. After meeting the ‘weird sisters’, Macbeth is told that he will become king and so his desire for the prophecy to become reality becomes an obsessive trait for him. Macbeth’s ambitions completely change his nature and ultimately alter his views upon the world by ruling out his moral and social conscience. Due to Macbeth’s ambitions, he is filled with the notion of being king and results to murder as the way of attaining the title while completely disregarding his morals. We will write a custom essay sample on Macbeth suggests that great ambition, or inordinate lust for power, ultimately brings ruin or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page He even questions himself as to why he suggests that murder will be the solution to his desires; â€Å"Why do I yield to that suggestion, whose horrid image doth unfix my hair and make my seated heart knock at my ribs. †(A1,S3) Through the quote the reader is made to see that his thought of murder is not intentional as he questions his own imagination, rather it is caused by his natural desires and ambition, which is not under his control. In pursuit of his desires Macbeth is completely blinded by his lust for power and discounts his morals and former traits, which ultimately bring him to his ruin. Even though Macbeth may seem to be the one responsible for his own destruction, Lady Macbeth also plays a major role, which impacts the tragic ending. In his rise to power, Macbeth did not personally have the ambition to take the throne. Even though he had no personal ambition, his greedy wife, Lady Macbeth, pushes him to take action in order to take the throne through murdering those ahead of him. â€Å"What beast was’t, then, that made you break the enterprise to me? When you durst do it, then you were a man. † Lady Macbeth questions his manly hood and furthermore forces Macbeth into direct involvement, which he would prefer to have avoided. Additionally, Lady Macbeth gives him false hope by stating prior to the execution of their plot that they would succeed without any other complications and that their plan would be flawless. However, through being pressured into murdering Duncan many other problems arise and Macbeth realizes that he is not safe as king yet, â€Å"we have scorch’d the snake, not kill’d it. † He then realizes that in order to maintain his safety many other murders have to take place. Thus, Macbeth employs several other murders to cover for the original murder, which Lady Macbeth was responsible for. The reader is made to see how Lady Macbeth manipulates Macbeth into all his decisions and so it is clear to see how she was solely responsible for Macbeth’s ambition, which led him to his own murderous behavior and ultimately his ruin. Macbeth is a man with many imperfections, which ultimately brought his ruin however along with his inordinate lust for power, his overconfidence was another major flaw in his traits that led to his defeat. As time passed, the witches’ influence on Macbeth gradually increased. Driven by dark ambition provoked by the witches, he begins to not only believe in the prophecies, but also commit to them, and puts his full trust in the witches. Towards the end of the play he even goes as far as to command the witches to show him more of the future: â€Å"I conjure you by that which you profess†¦ answer me to that what I ask you. † Because of Macbeth’s overconfidence in the witches, he interprets the apparitions as encouragement instead of warnings and becomes reckless with his actions. He becomes careless because he ignores his rational side, and follows his desires, blindly. A significant example of Macbeth’s overconfidence is towards the end of the play where he faces Macduff. He is convinced that he cannot be harmed by any man of women born, and becomes careless into thinking that he is invincible. He later finds out that Macduff was, â€Å"untimely ripp’d,† from his mother’s womb however it much too late and due to his recklessness he was defeated. Macbeth’s overconfidence and his feeling of security can be said to be his â€Å"biggest enemies,† or flaws, which ultimately brought him to his ruin. Macbeth’s ruin is a result of Lady Macduff misdirecting him and two of his biggest flaws: his overconfidence and his ambitions or inordinate lust for power. These traits that Macbeth developed became more serious over time and his constant need to fulfil his ambition was what blinded him from his social and moral conscience, which ultimately led to his fall.
