Relational And Non Relational Database Model Essay

2 Literature Review Many theories have been written to clearly explain the concept of relational and non-relational databases. Although those literature hightligted varieties of significant theories, this review will attempt to establish a clear meaning of relational and non-relational database Concept, NoSQL data model, ACID and Base properties, CAP Theorem and Scalability. Furthermore, it will attempt to critically evaluate structured and unstructured data, elucidate on the strength and weakness of relational and NoSQL databases and give an overview of the benchmarks used to evaluate the reliability and performance of databases. 2.1 Relational and Non-Relational Database Concept The relational database model was invented in 1970, by Edgar Ted Codd, a Mathematician at IBM’s San Jose Research Lab in California, United States of America. At the time, nobody realized that Codd’s theories would spark a technological database revolution. Until 1970, a database stored large volume of data using hierarchical data model that was difficult to navigate and lacks flexibility [8]. Today, the benefits brought to us by relational database model are enormous. Ted Codd in his paper titled A Relational Model of Data for Large Shared Data Banks†, he created and visualize the concepts for organizing and accessing data that is embodied in the relational database, he proposed that data should be structured according to principles based on identified relations [9].

Richard Wrights Native Son Free Essay Example, 1000 words

He warns how there will be more men like Bigger if America does not put an end to it. Nevertheless, Bigger is sentenced to death. Bigger is not a traditional hero by any means (Wright 2010). Wright forces us to enter into Bigger’s mind and to understand the devastating effects of the social conditions in which he was raised. Bigger was not born a violent criminal. He is a â€Å"native son†: a product of American culture and the violence and racism that suffuse it. Richard Wright himself was born on a farm in Mississippi in September 1908, and although he attended a porochial school, much like Bigger Thomas in Native Son he was rebellious. An illnesses Wright’s mother suffered drained the family and forced him to work a number of jobs during his formative years, but despite sporadic schooling, he graduated valedictorian of his junior high school, but financial troubles worsened. Wright was forced to drop out of high school after only a few weeks to work. Just pri or to the Great Depression, his family moved to Chicago, where Wright devoted himself seriously to writing. In 1934, Wright became a member of the Communist Party and began publishing articles and poetry in numerous left-wing publications (McAdam 1999).

Native Son stirred controversy shocking the sensibilities of both black and white America. He wanted readers to see the inequity of race relations. Wright does not inoculate Bigger with any romantic traits so common to literary heroes. Instead, Bigger is a resentful product of his world. Bigger is a fusion of men Wright had himself known growing up in the South. Confronted by racism and oppression and left with few options, many became antisocial and violent. They were disasters waiting to happen. In some ways, Bigger Thomas is Richard Wright. In the late 1940s, Wright became involved in the existentialist movement. Native Son is Wright’s warning that if American did not change, the oppressed would rise up against the power structure. It is clear to see how Richard Wright’s expe riences in 1930s America influenced his writing of Native Son. Like Bigger, Richard had not only seen others suffer under the sociopolitical economic status quo of the time but he himself had also experienced the difficulty. Knowing the details, it is not difficult to understand his message. If people’s lives are difficult enough, they become like trapped animals and may act out not much differently.

Parliamentary vs Presidential Governments Free Essays

In a democratic government there are two most popular types of government: presidential and parliamentary. They are somewhat similar, but their branches, executive,legislative, and judicial, work differently and are responsible for quite different jobs. Most European countries run by the parliamentary systems, such as Britain, because it once was monarchy. We will write a custom essay sample on Parliamentary vs Presidential Governments or any similar topic only for you Order Now Even now the Great Britain has a Queen Elizabeth II. Countries like the United States are ran by the presidential form of government. The most significant difference in the Parliamentary form of government versus the Presidential is that the president is both the chief executive and the head of state. The President has the power to veto laws, execute the instructions of Congress when it declares war, has the right to approve the treaties without the legislature’s permission. The president has the right to deploy military, but cannot declare war. Parliamentary system divides the chief executive and the head of state into two separate offices. The chief executive is usually the Prime Minister and the head of state is the president. In Britain, for example, the chief executive is the Prime Minister, and the head of state is the queen Elizabeth II. The Prime Minister is usually the highest political authority in the country and is the head of the Cabinet, or the executive office. He does all the decision making, approves laws, nominates all the ministers and the Cabinet members, has authority to control all the governmental departments. another big difference between the two governments is how they get elected. In Presidential government, for example in the United States, the candidate for presidency is being elected by the Cabinet or the Senate, further to be selected by the votes of the nation. The Prime Minister, as in Britain, is elected by the Cabinet. People do not vote for him, but they do vote for the congressmen, who may soon become the Prime Minister. The President and the Prime Minister are both people with the most authorities in their country, and both can be dismissed at any point in time by the Cabinet. The Presidential system and the Parliamentary system differ in each country, because each country has its own constitution. For example in Great Brittan, the person with the most authority is the Prime Minister, but in Russia, it is the President, even thought Russia has a Prime Minister. The two democracies work the same way, only people with the same titles do different jobs, and people with similar jobs have a different title.
