Introduction: In this document I am going to explain what database is and then I am going to list four different types of database and their pros and cons (Advantages and Disadvantages) for all databases that has been listed. And finally I am going to give an example of each database when it can be used. What is a Database? A database is a group of data and ii is often shortened DB. They are mainly or normally used for two purposes. Storing data and sorting data. You can save different types of information that is organised so that you could easily access in a database. Databases usually have a lot of information kept in it and you can filter through the data very simply. Database work very similar to spreadsheets as, spreadsheets have got rows and columns, similarly, database also have. For example, the company stores all the names of employers and employee with their personal information. Company can separate their employee and employer by giving each individual an ID number which symbolizes an individual. This is mainly stored into the database and it is the basic method of filtering. Now I am going to talk about the different databases. Which are 1) Flat File, 2) Relational Database, 3) Network Database and 4) Hierarchical Database? And I am going to talk about them and their pros and cons and also I am going to give an example for each of them. Flat File: A flat file is a collection of data stored in one big table. It is a fairly simple and straightforward databaseShow MoreRelatedAnnotated Bibliography On Non Relational Databases Essay1072 Words   |  5 Pagesof NoSQL databases has risen in the past decade as traditional relational databases cannot handle the vast amount of data as it was not designed to effectively manage such a large data collection.

Why Gangs Are Built Through A Process Of Selection Essay

Gangs are built through a process of selective recruitment, based on a foundation of trust. Trust is gained through activities that reveal the recruits level of discipline, strength, and vulnerability. Potential gang members are typically chosen, although some choose the gang life. Nevertheless, both are typically seeking to fulfill a need to belong and make money, while obtaining security and familiarity. This slippery slope usually leads to death or jail, although Christ can set gang members free. Gangs The presence of gangs is an ongoing issue amongst a growing population of individuals who are often recruited, appearing to have a desire to belong, generate money, and obtain a sense of security. The gang life is often a dangerous slippery slope that leads to a lifetime of criminal activity or simply increases the already existing criminal behavior in the gang member. For some, there remains a hope for conversion. Recruitment- Selection begins Recruitment of gang members occurs through a process of selection (Densley, 2012, p. 302). Selection â€Å"is a key component† in recruitment, completed through the observation of various risk factors revealed in â€Å"daily interactions† in the lives of potential gang members (Densley, 2012, pp. 302, 308). Recruiters are known to watch for durability and strength in those whom they believe may be beneficial to the gang (Densley, 2012, p. 302).

Essay on The Dangers of Fracking Essay Example For Students

Essay on The Dangers of Fracking Essay With the age of constant industrial and technological growth has come the necessity for not only cost effective and efficient methods for industry, but also the need for obtaining fuel for the machines that make the modern world possible. Oil has become as precious a commodity as gold, if not more so; its attainments constantly driving the worlds largest businesses and governments across the world into action. Naturally, a quick-fix solution to this problem is constantly sought after by oil companies wishing to provide oil on a massive scale. One of these drilling methods is known as induced hydraulic fracturing (also known as fracking). Fracking is a process in which a drill is inserted into a shale, which is a cracked surface, usually rock or clay, under which oil is expected or estimated to lie. The drill then blasts the underground well with large amounts of a liquid, usually water with added chemicals for fluidity. The fracturing occurs within the ground and/or rock formation when the water pressure is applied and veins are created for oil to flow through freely. Whereas a typical oil rig can only pump for oil vertically, many companies that induce fracturing will drill vertically as well, creating more possibilities for the procurement of natural gas and oil. The first instance of the processess use was in Barnett, TX, in the Barnett Shale, and has been going on for over 50 years with what some would say has been spotty government regulation, and which others would say has been too much or unwarranted in the instances in which it has occurred.

Oedipus Symbolism Essay Example

Oedipus Symbolism Paper Oedipus Symbolism Many stories from ancient times as well as present times use symbolism to prove a point or to help with the understanding of the story. Symbolisms are used in stories and plays of all kinds to help get a point across or to help clarify the meaning of the story, and the play, Oedipus the King, is no different. There are many things throughout the play that are symbolic and very important to the understanding of the play. Two of the major symbolic things in the play are blindness and binding. Both of these things have a deeper meaning than simply the literal meaning of the words used to describe them. Blindness is used as a symbol to understanding, and is seen as a physical blindness and well as a spiritual blindness with both having equal importance in showing that just because a person can see something does not mean that they understand what they are seeing or what they are supposed to see. The binding is used to help show that the prophecies of the gods will be fulfilled regardless of what man does to try and stop them. The physical binding is used to symbolize that regardless of what types of interventions are implemented, some things are just destined to be.

The first of the two symbolic things is blindness, which is used as a symbol to understanding. There are many references throughout the play about sight, seeing, blindness, and vision. Even though all of these words can essentially refer to the physical sight created by the human eyes, that is not what all of these words refer to in the play. Teiresias was a man who was physically blind and unable to see the things around him through his eyes, however when it comes to spiritual sight he could see everything clearly. Teiresias understood everything that had happened and he warned Oedipus that he did not want to know who killed his father, but Oedipus kept prying. Oedipus was the exact opposite of Teiresias when it came to blindness because Oedipus was able to physically see but was blinded spiritually as he was unable to see the truth of his life. Once everything became clear to Oedipus, he blinded himself physically by gouging out his own eyes because he was ashamed of the things that he had done. He did not like the truths that had been unveiled and he made himself physically blind after he gained his spiritual sight. Wilkie and Hurt) The second of the two symbolic things is binding. As an infant, Oedipus’ feet were literally pierced and bound together by his parents, and he was sent away to be killed. His parents did this because it had been prophesied that he would someday kill his father and sleep with his mother. However, he was not killed, but he was taken in by another family who r aised him. The physical binding of his feet left a permanent scar on him and it caused him to walk with a limp when he grew up, and it also played a large role in how he came to get his name. The binding has more than just a physical meaning though. It can also be looked at as if he was bound to the fact that he would kill his father and fulfill the things that had been prophesied by the gods. Even though his parents had tried to stop destiny by having their child sent away to be killed, in a way it seems as if they actually enabled the prophecy to be fulfilled. If Oedipus had known that it was his father that he met at the crossroads, then he probably would not have killed him. Likewise, if he had known that his mother was the prize for solving the riddle, then he probably would not have accepted the challenge or the prize. All of the people, including Oedipus, were bound to the predictions of the gods and there was nothing that any of them could do to change it. The scars on Oedipus’ feet were symbolic of being bound to the prophecy and the scars were what allowed the truth of who he really was to be proven to be true. (wikipedia. org) The symbolism throughout the play is what makes the play so memorable. Sophocles did not need to have a blind man be the one who revealed to Oedipus the truth of who murdered his father, but the fact that the man was blind simply makes the story that much better. He was blind only in the physical manner, while Oedipus was blinded spiritually. It offers the thought that just because one can see with their eyes does not mean that they are actually looking at the information right in front of them. A person may have perfect vision and be completely blinded to the truths of their being or their surroundings. The symbolism of the binding is also an important one because it shows that some things are destined to happen regardless of what interventions are utilized. The same story could have been told without the different symbolisms but it would most definitely not e the same. It may have had the same story line and the same outcome as far as who the characters were and what they did, but the meaning behind the story would have been lost. Stories with symbolism generally pull people in and tend to engrave on their memory the meaning behind it. Without symbolism this would simply be a story with far less meaning.
