Overview: This section describes the purpose of this research, the rationales for undertaking it and the background knowledge that is relevant to this research. It provides the research background that describes the polemic in the Database Management Systems (DBMS); research question in regards of performance of MySQL (non cluster) and Hadoop; the research aim; the research objectives; and the research outline.
1.1. Background
The weakness of the relational database unfolded by the rise of web-driven application (Lake and Crowther, 2013; Dede et al., 2013), whereas non-relational database gained their popularity (Li and Manoharan, 2013; Parker et al., 2013; Prasad and Gohil, 2014). However, since it was believed that a relational and a non-relational database had a different function, therefore Parker et al. (2013); Tudorica and Bucur (2011) stated that those databases were not comparable. Relational database appropriates for modest structured dataset, while non-relational database suitable for large unstructured dataset (Parker et al., 2013).
In regards of choosing a database platform, it was recommended to choose a database platform that had an excellent performance (A MySQL AB, 2005; Lake and Crowther, 2013; Kulshrestha and Sachdeva, 2014). In the era of web-driven database application, it is necessary to have an excellent performance of database due to the necessity of processing a huge amount of data traffic (Butcher and Maslakowsky, 2003).
Due to the important role
Which database management system platform should I use? This is a very common question that developers ask themselves when they work on a project that requires storing and querying data. There are 4 well-known platforms that people may consider; they are: Oracle, Microsoft SQL, Teradata and DB2. This essay will compare and contrast the differences and similarities between these fours platforms.
Relational database contains data records that do not have a preset of relationships, permitting the user to define his or her relationship when accessing the data. Since users have much control over the data being accessed, relational databases can perform a variety of tasks. Such as defining the database; querying the database; adding, editing, and deleting data from the database; modifying the structure of the database; securing data from public access; communicating within the network; and exporting and importing data (Murthy, 2008).
Abstract – With companies such as Facebook and Google producing large volumes of data, known as Big Data, the popularity of 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. The following research paper gives an introduction to non-relational databases otherwise known as NoSQL. It defines what a NoSQL database is, the origins of its existence and the various types of NoSQL databases. It goes on to discuss the advantages and disadvantages of non-relational databases and the reason companies in the past decade are selecting to implement these databases over traditional relational databases.
The paper “A Comparison to Approaches to Large-Scale Data Analysis” by Pavlo, compares and analyze the MapReduce framework with the parallel DBMSs, for large scale data analysis. It benchmarks the open source Hadoop, build over MapReduce, with two parallel SQL databases, Vertica and a second system form a major relational vendor (DBMS-X), to conclude that parallel databases clearly outperform Hadoop on the same hardware over 100 nodes. Averaged across 5 tasks on 100 nodes, Vertica was 2.3 faster than DBMS-X which in turn was 3.2 times faster than MapReduce. In general, the parallel SQL DBMSs were significantly faster and required less code to implement each task, but took longer to tune and load the data. Finally, the paper talk about
1) Before using any DBMS, the creators should have created a data model from the users' requirements.
The main purpose of this report is to provide a critical review of the processes and own experiences of Hadoop within the context of the assignment which was given to us. The review concentrates on the discussion and evaluation of the overall steps followed during the progress of the project and the reasons for which we have chosen these particular steps. It also draws attention at the main points that were accomplished, both with respect to individual, and with respect to the group 's perspectives. Finally, it concentrates on the project 's progress in terms of changes for a future implementation.
Current trend in the world of information technology is that relatively every organization is managing tens of petabyte of data. There are large proportion of data which need to be store and managed in database. So there is immense requirement of efficient and reliable database management system. Database systems need to be constructed in high reliability methods and techniques in terms of their functionalities and design. System Performance is an analytical metric that must need great output for an effective database system. Complex database system is outrageous and difficult to analyze so performance evaluation is very important concern since databases are one of the most compelling affair in today’s business revolution.
As I talk to customers about Hadoop, they share some dos and don’ts based on their experience. Please kKeep in mind that there will be many more best practices as the technology matures into the mainstream and is implemented.
This paper will provide you with a detailed knowledge of how by choosing the correct database processing and query language you are able to mitigate the processing capacity problems that are involved with the vast growth of data recently. This will help to show that while there may be no one size fits all answer, there is a fit for the problem at hand based on the storage, processing, and query needs that are to be met.
Hadoop is an open source framework that could be very resourceful in data processing of the complex data systems, and has been reverently used in the recent past for query processing in the complex databases that contains millions of records. The major advantage of Hadoop is that it clusters the entire records to few blocks and the query is run on each cluster and the compiled information is displayed in effective terms.
The relational database technology dominated the web applications for more than 30 years. This technology is able to handle limited load to the database. However, the internet technologies and the advents of the smart phones make the web applications to be accessible by many users and from any location that is covered by the internet connectivity. In addition, currently, the web data in the internet is dominated by the social networking and social media applications which include: Facebook, Twitter, YouTube, Instagram and others. This kind of web applications will likely be prone to the high load of the database layer. As a result, it was not possible for the relational database technology to handle the database load for such applications. Even scaling out the application servers will not solve the database load
The modern RDBMS advancements are not capable of supporting unstructured information with ideal space necessity. The plan winds up plainly mind-boggling and is henceforth troublesome for designers. The requirement for unstructured information administration is so annoying with conventional RDBMS arrangements (Big data in financial services industry: Market trends, challenges, and prospects 2013 - 2018). Moreover, RDBMS turns out to be an exorbitant answer for creating light-footed web applications with direct information investigation necessities. NoSQL is developing as a proficient possibility in this situation, which connects the issues related with RDBMS innovation. The market development can credit to creative dispatches of NoSQL arrangements, and collective endeavors by NoSQL sellers and clients. The endeavors of organizations, to enhance their market offerings, are creating the request of NoSQL, as a back-end bolster (Big data in financial services industry: Market trends, challenges, and prospects 2013 - 2018). The emergence of agile software development is creating the demand for NoSQL (Big data in financial services industry: Market trends, challenges, and prospects 2013 - 2018). They offer users much more avenues to accept data in many different forms. NoSQL is adaptable as SQL but offers many more uses that can apply to many organizations.
Abstract—Parallel databases are the high performance databases in RDBMS world that can used for setting up data intensive enterprise data warehouse but they lack scalability whereas, MapReduce paradigm highly supports scalability, nevertheless cannot perform as good as parallel databases. Deriving an architectural hybrid model of best of both worlds that can support high performance and scalability at the same time.
In Nowadays, there are two major of database management systems which are used 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
Information technology continues to revolutionize the interactions of mankind in various ways, through social media, business, education and other channels. The internet has made it possible to transmit large data across many networks. These networks have made it possible to store, access and query billion of data from large databases. Innovation has given rise to special language used to manage and access all sorts of information within various databases know as SQL. Recently a new generation of SQL known as NoSQL has been developed. NoSQL store related data in JSON-like, name-value documents and can store data without specifying a schema. One such type of NoSQL database that has been developed is the IBM Informix
