Description Of A Relational Database - 1366 Words

NoSQL is the generalized term to describe a relational database that uses no form of SQL language querying and consists of several data models to define it. My topic of this research paper is the Document Store data model. I will be covering the introduction of the model and its mechanics, how and when the model emerged, its strengths and weaknesses, and it’s real world applications. Introduction and How it Works Document Store or â€Å"Document-oriented database† is a data model within the NoSQL family, made for storing, retrieving, and managing document based information. The concept revolves around documents containing large amounts of data. A variety of documents are accepted, from there they are encapsulated into an internal format, and†¦show more content†¦Both use the Document database concept, but differ in it’s process and tools. Julie Lerman explains in her article â€Å"What the Heck Are Document Databases† that Raven DB was written for the Microsoft .NET Framework and growing in popularity. Model Emergence In the 1970s, relational databases were introduced with data schemas simple and straightforward, conceiving objects as sets of relationships. as mentioned in the Document Database webpage â€Å"an article object might be related to category (an object), a tag (another object), and a comment (another object)†. These relationships between different types of data were defined in a database schema, the relational database could be queried with a standard Structured Query Language (SQL). These SQL based databases require a fixed amount of tables, a fixed amount of columns in each table, with each column represent a fixed data type (integer, string, etc). Consequently fields of data stored in each column must comply with the structure of the database and its tables. whatever data you want to store must be known to create an appropriate database schema, this is the concept behind relational databases. NoSQL was created to remedy the architecture of relational databases, to make the schema more dynamic and ever expanding. With the emergence of cloud computing, unstructured data such as social media posts in need of storage, and Agile development practice, The Document

How Industrialization Changed The Social, Political, And...

Industrialization changed the social, political, and economic face of America’s cities. A model of the reforms that society was experiencing can be found in the nation’s school system. Progressive changes took place in schools in the forms of â€Å"change in political control of education; change in educational thought; innovations in school curriculum and other practices; justification of schooling in terms of professionalism; and the importing of scientific management into school administration† (p. 179). Each of these areas deserves reflection and analytical thought. However, as I was reading Urban and Wagoner’s American Education: A History, Chapter Seven: Organizing the Modern School System: Educational Reform in the Progressive Era, 1890-1915 (2014), the part that had me asking the most questions and contemplating differences of opinion, was on the subject of progressive reforms in curriculum development. More specifically, considering my reactions t o the Committee of Ten findings. People then, as much as today, had different ideas about what the purpose of secondary education should be, and as result they differed in their opinions regarding what should be taught to students in high schools. Before the era of Urbanization and Industrialization, secondary education was seen as a means to prepare students for college and for moral development. However, by the late nineteenth and early twentieth centuries, America had changed. High schools were educating many students whoShow MoreRelatedMidterm Exam Study Guide Exam2366 Words   |  10 Pages desert is hot and sandy Movement (how do things move around the world?) movement of people, goods, and ideas from one location to another ex. running, driving, social media, imports and exports Region (how are places similar?) area defined by similar formal or functional characteristics ex.

Gerald Crofts Essay Example For Students

Gerald Crofts Essay In what ways does Priestly present the effects of the Inspectors visit on Sheila Birling in the play? J. B Priestley uses a variety of dramatic techniques to portray the effects of Inspector Gooles visit on Sheila Birling. These devices include dialogue, physical action, stage directions and dramatic tension. Priestley places Sheila at the moral centre of the play. The Inspectors visit takes her through an array of emotions in a very compressed time span which heightens Sheilas anxiety and speeds her transformation. The action is played out in real time i.e. the events unfold on stage exactly as they would in real life. Many modern dramas have copied Priestleys theatrical technique (24 TV series, and some episodes of E. R). At the beginning Sheila is shallow and very pleased with life and rather excited. She later admits that she had been confident and pleased with herself. We know this, as she likes money and possessions- Gerald Crofts ring (Oh its wonderful) and clothes. But from this beginning, when this rich family are celebrating Sheilas engagement (which is more like a company merger in Mr. Birlings eyes), their entire world is turned upside down. Sheila feels everything most deeply and Priestley has the Inspector repeat Eva Smiths agonising and unpleasant death by disinfectant several times which adds to her distress. Priestley starts Sheilas transformation half-way into the 1st Act. When Sheila hears of the death she is genuinely distressed but she is still selfish because she is annoyed that her evening has been ruined (Ive been so happy tonight. Wish you hadnt told me). Priestley continues the transformation by giving Sheila the beginnings of a social conscience. When Sheila realises that Eva was sacked for asking for a pay rise, she tells her father that it was a mean thing to do. Priestley also brings about her political awareness. The Inspector points out that desperate girls like Eva feed the capitalist free market for cheap labour. Priestley ensures that she takes a compassionate line, even though she has probably never considered the conditions of the workers: But these girls arent cheap labour- theyre people. Priestley uses dialogue very cleverly, especially when the Inspector suggests the entire family should try and put themselves in the place of these unfortunate young women in their dingy little back bedrooms. He ensures Sheila empathises with Eva. When Sheila realises she was responsible for Evas dismissal from Milwards, Priestley introduces physical action. Sheila half stifles a sob and runs out. This tremendous physical reaction is very powerful because it is the first bit of action and it heightens Sheilas distress. When she returns she has been crying. Priestley continues her descent into misery so that in pain Sheila asks So Im really responsible? Priestley makes Sheila confront her own jealousy and pettiness by her acceptance that she had allowed her own bad temper and anger to have Eva dismissed from her job. Priestley shows the class-based economic power that Sheila possessed. By the end of the 1st Act Priestley shows that Sheila is full of guilt and remorse. Sheila realises that Evas prettiness made her even more determined to have her sacked. During this long speech Sheila confesses her own part, and she almost breaks down. It is a speech full of pathos (sadness, sorrow). Priestley uses repetition of words to show Sheilas anguish and sense of guilt: I know, I know Ill never, never do it again. This also shows that Sheila is keen and anxious to change her behaviour in the future. Sheila is full of guilt and says If I could help her now. Before the end of Act 1, Priestley adds to Sheilas grief by showing that she has been betrayed by Gerald Crofts disloyalty the previous summer.
