Abstract: In Nowadays, there are two major of database management systems which are use to deal with data, the first one called Relational Database Management System (RDBMS) which is the traditional relational databases, it deals with structured data and have been popular since decades since 1970, while the second one called Not only Structure Query Language databases (NoSQL), they are dealing with semi-structured and unstructured data; the NoSQL types are gaining their popularity with the development of the internet and the social media since April 2009. NoSQL are intending to override the cons of RDBMs, such as fixed schemas, JOIN operations and handling the scalability problems. In this paper we will review one of the graph database (Neo4j), which the graph database is part of the emerging technology that is called NoSQL and compared it with one of the traditional relational database (MySQL).

A Brief History of America’s National Pastime - 679 Words

According to a passage in the 19th Century Baseball website, author Eric Miklich writes that America’s pastime may have originated in Canada. Miklich tells the story of Dr. Adam E. Ford who wrote a letter about a game which had been played in 1838 which was described to have several key differences than baseball. Many people believe that baseball evolved from games played in England- mainly cricket and rounders. Others believe the German game of town ball is where it all started. October 6, 1845 was the first baseball game on record. One of the teams playing that day were the New York Knickerbockers. The Knickerbockers, led by â€Å"The Father of Baseball† Alexander Cartwright, are known today as the first official baseball team. Cartwright published the original rules of baseball (Miklich). Throughout the years, baseball has seen it’s fair share of great players and managers while evolving into the sport we know and love today, but not without controversy. Since Cartwright and the Knickerbockers, the game has seen an explosion in popularity. The first boom in popularity occurred during the civil war. Terry Bluett is author of the article â€Å"Baseball and the Civil War† where he explains prior to the civil war, baseball was a game that was only played in the New York area. Those who played the game and went off to war began to teach their fellow soldiers how to play.

A Modern Macbeth Essay Example For Students

A Modern Macbeth Essay A Modern MacbethWhen looking back on the recent decades or even last week, it is not difficult to find a Macbeth-like figure in mainstream American culture. In this it is meant that these individuals experience a downfall in an attempt to gain power. One such figure was former President Richard Nixon. Nixon was long associated with American politics before his fall from grace. He was along time senator before finally being elected president in 1968. During his first term, his United States went through the Vietnam War and a period of economic inflation. In 1972 he was easily re-elected over Democrat nominee George McGovern. Almost unnoticed during his campaign was the arrest of five men connected with Nixons re-election committee. They had broken into the Democrats national head quarters in the Watergate apartment complex, in Washington D.C. They attempted to steal documents and place wire taps on the telephones. By March of 1973, through a federal inquiry, it had been brought to light that the burglars had connections with high government officials and Nixons closest aids. Despite Nixon and his lawyers best efforts, it was shown that the president had participated in the Watergate cover-up. On August 8, 1974 Nixon announced, without admitting guilt, that he would resign. He left the Oval Office the next day: an obvious fall from grace. So how does this former leader of the free world compare to Macbeth? Before they achieved their positions of power to govern or rule all, both Nixon and Macbeth spent many years being heavily respected amongst their peers. Nixon spent many years as a respected congressman and Macbeth as a soldier and Thane of Glamis. They used the way people viewed them to their advantage to gain a position of power. Nixon used his experience to get him elected president. Macbeth was made Thane of Cawdor and eventually king. Once they both ascended to their respected roles they did whatever it took to protect themselves from any possible threats. Nixon cheated by trying to steal opponents campaign secrets thus giving him an unfair advantage. Macbeth either killed or tried to intimidate anyone that he felt was in his way. Murder cannot be equated to spying but the main idea is that they both did whatever it took to maintain their power. Like Shakespeares Macbeth, Richard Nixon ascended to power only to have a downfall and end up with nothing. It was their attempt to gain and maintain this power that lead to this fall from grace.

The British government system, The Indian Civil Service, excluded Indians from positions rendering them without say in their own government. Additionally, the British passed many laws including the prohibiting the making of salt and purchase of only British cloth. Indians were forced to pay tax on common foods such as grain and salt. Mahatma Gandhi created a sense of nationalism or patriotism, and formed the â€Å"Quit India† campaign. Using civil disobedience, purposely defying an unjust law, and non-violent resistance, peaceful tactics, such as fasting. Nelson Mandela similarly led Africa to its freedom from apartheid created by the National Party. The apartheid divided and separated the Africans into four categories: White, Black, Colored, and Asian. Analogous to the Indian Civil Service the National Party striped all races except whites of their say in government such as voting rights and positions in political offices.

Nelson Mandela achieved independence by becoming a radical member of the African National Congress which originally held peaceful protests like Gandhi, but transitioned into violence with gained Africa’s freedom. Because of Mandela’s crucial role in African independence he was elected president of South Africa. Jefferson uniformly to Gandhi and Mandela gained independence for America from Britain’s abusive leadership. Under British rule the colonies were also deprived of representation in government. Like India and Africa, laws were imposed on the colonies such as the Intolerable Acts which stripped the colonies of rights and freedom. Also identical to India and Africa were taxes inflicted on the colonies such as the stamp act, which required tax on all legal documents and the taxing of tea. Thomas Jefferson like Mandela joined a group set on freedom, the Continental Congress committee. Jefferson largest contribution was writing the Declaration of Independence which finalized the separation from Britain. Each of these influential leaders similarly led their country to independence. Each event in history holds undeniable correspondence. As each leader endured unrepresentative government, tax and laws they gained independence. Although rulers, languages, and cultures change through the years, history always returns to a repetitive tendency. Gandhi, Mandela, and Jefferson all analogously led their countries to independence showing a redundant fashion.

Medtronic Essay Example | Topics and Well Written Essays - 750 words

Medtronic - Essay Example Help analyse the underlying causes, strengths and weaknesses, market forces and factors that affect performance to determine the optimum objectives that the organization may target. Having briefly defined the role of the Board we look at how the Board of Directors of Medtronics has performed. Details provided in the case study paint a very positive picture of the proactive role that the Board has played in the success of the Company. It has done all that is required and gone several steps further. The role that the Board has played in strict adherence to the mission statement of the company and, in the drive of the company to excel in technology and quality initiatives is indeed commendable. The Board has been a friend and guide for management, evidenced by the comment of Bill George, "In addition to its traditional role of governance, the Medtronic board is very effective as a sounding board, to advise and consult with management on the challenges we face." (p1) or that of Earl Bakken, "As we have grown and evolved, we have leaned on our board of directors for their direction." (p3). The active interest that the Board has taken in the operations of the company, their focus on the long term, regardless of below par performance on the financial front, represent some of the peculiarities of the Medtronic board that may not be found in most companies. It is usual for boards to look at only financial performance for the quarter and stop at that. It is truly amazing to find a board that has such faith in the future of the company that temporary setbacks on the earnings per share (see performance results) have not led to the typical automatic reaction. As Bill George points out in his book "Authentic Leadership", the board was successful in grappling with the larger ethical issues of what an organization owes to the public and its employees beyond the narrow obligation to increase shareholder value. The relationship between the CEO, Bill George and the board are similarly cordial and mutual understanding and respect at a very high level exists. While the CEO handles operational management, he does not consider the careful watch that the board keeps
