...INSY 5337 Data Warehousing – Term Paper NoSQL Databases: An Introduction and Comparison between Dynamo, MongoDB and Cassandra Authored ByNitin Shewale Aditya Kashyap Akshay Vadnere Vivek Adithya Aditya Trilok Abstract Data volumes have been growing exponentially in recent years, this increase in data across all the business domains have played a significant part in the analysis and structuring of data. NoSQL databases are becoming popular as more organizations consider it as a feasible option because of its schema-less structure along with its capability of handling BIG Data. In this paper, we talk about various types of NoSQL databases based on implementation perspective like key store, columnar and document oriented. This research paper covers the consolidated applied interpretation of NoSQL system, depending on the various database features like security, concurrency control, partitioning, replication, Read/Write implementation. We also would draw out comparisons among the popular products and recommend a particular NoSQL solution on the above mentioned factors. 1. Introduction Until recently, Relational database systems have been on the forefront of data storage and management operations. The advent of mobile applications that requires real time analysis like GPS based services, banking and social media has led to huge unstructured data being produced every second. Traditional RDBMS systems have found it difficult to cater to these huge chunks of unstructured...

...Big Data [Name of Writer] [Name of Institution] Introduction The term Big Data is gaining more followers and popularity. However, despite this trend, not all organizations are clear about how to face the challenge to store, organize, display and analyze large volumes of data. The term Big Data is gaining more followers and popularity. However, despite this trend so evident, not all organizations are clear about how to face the challenge to store, organize, display and analyze large volumes of data. There are multiple techniques in terms of huge database storing approaches that can store petabytes, exabytes and may be zetabytes data. These options are Cassendara, Mongodb and HBase. We will discuss about them one by one and in a proper research method and will compare them in order to contrast their difference and efficiency. Research Background One problem in understanding the phenomenon is that the size of these data sets the volume greatly exceeds the Data warehouse. A plane collects 10 terabytes of information from sensors every 30 minutes flight, while the Stock Exchange of New York collects structured information 1 TB per day. In the context of Big Data, volumes are reaching peta bytes, exa bytes and then soon to zeta bytes. For instance, Apple has just announced that 7 trillion send daily notifications to iOS devices. The explosion of information in social networks, blogs, and emails is characterized the presence of data key...

...Big Data and NoSQL Abstract The combination between Big Data and NoSQL is one made of inevitability. As data grows larger and larger, the weaknesses in the relational data model are exacerbated. NoSQL technologies grew out of the need for fast query speed and real-time analytics from data sources too large for traditional SQL. Introduction A web site running with a large number of users/members will experience the dreaded Big Data Performance Inconsistency. When you need the web site to respond more quickly to a successful, it slackens. Sites like Facebook, Twitter, and others have struggled with this problem for years as they’ve grown from thousands to millions and now hundreds of millions of users. Inundated by huge amounts of user data, they took advantage of data store technologies like Memcached and Redis to make their sites run fast. But for sites without the engineering resources of companies like Facebook, adopting these technologies has been challenging. Big data and NoSQL Big Data company for example Garantia Data addresses above issue. Garantia Data’s cloud-based, in-memory NoSQL solutions make web site run faster. That’s why a number of companies are beta testing Garantia Data’s offering. NoSQL is often used for storing Big Data. This is a new type of database which is becoming more and more popular among web companies today. Proponents of NoSQL solutions state that they provide simpler scalability and improved performance relative to traditional relational...

This report analyzes the some of the most important changes that are currently taking place within this new paradigm. The first part of this report covers trends in database analysis by analyzing the field of data mining. The report covers the topic of data mining by providing an explanation of it, and then by providing examples of real-world examples of data mining technology. Benefits and challenges of data mining are then provided. The second part of the report outlines an even more recent trend in data science, which is the increasing usage of noSQL databases to analyze “big data,” also referred to web-scale datasets. The most recent and major technological developments in the industry are then provided and described. Data Mining Background & Definition Data mining involves the process of discovering and extracting new knowledge from the analysis of large data sets. This is most often done through the use of data mining software, which identifies correlations between different variables in a given data set. Data mining is primarily used to analyze data stored in relational databases, which consists of tables joined together by key variables in each.1 For nearly thirty years, relational database systems have been the primary type of database used to store data...

...redundancy. Relational DataBase tables – relational model emerged due to list problems. It is a collection of separate tables. Table holds data for only one theme, not multiple. When evaluating a database design, consider mod actions: insert/delete/update. Structured Query Language SQL – leading tech for data definition and manipulation. Can reconstruct lists from their underlying tables, query for specific data conditions, perform computations, can update/delete/insert data. Database System four components: * Database – collection of related tables and other structures * Database Management System DBMS – computer program used to create, process, and administer the database. Receives requests encoded in SQL and translates them into action on the database. Large complicated program licensed by software vendors. * Database Application – Set of one or more computer programs that serves as an intermediary between the user and the DBMS, These programs read or modify data by sending SQL statements to the DBMS. * Users – use the DB Application to keep track of things. Use forms to read, enter, and query data. Database – defined as self-describing (a description of the structure if the database is contained within the database itself) relational collection of tables. Metadata – data about the structure of the a database. (IE names of tables, names of columns, and the tables in which they belong, properties of tables and columns) Database contents – user data...

...Database Design Paper DBM380 March 09, 2015 Database Design Paper A database is a computer structure that organizes a collection of data so that it can be accessed, updated and managed as fast and efficiently as possible. There are several classifications of databases, “For example, databases can be classified by the number of users supported, where the data are located, the type of data stored, the intended data usage, and the degree to which the data are structured. The number of users determines whether the database is classified as single-user or multiuser. A single-user database supports only one user at a time. In other words, if user A is using the database, users B and C must wait until user A is done. A single-user database that runs on a personal computer is called a desktop database. In contrast, a multiuser database supports multiple users at the same time. When the multiuser database supports a relatively small number of users (usually fewer than 50) or a specific department within an organization, it is called a workgroup database. When the database is used by the entire organization and supports many users (more than 50, usually hundreds) across many departments, the database is known as an enterprise database” (Coronel, Morris, & Rob, 2013, p. 9). Database architecture describes the rules that dictate how data is stored in a database and how data is accessed by components of a system. Database management software, such as Oracle, is designed to handle...

...A database management system (DBMS) “creates, reads, updates, and deletes data in a database while controlling access and security” (Baltzan, 2015, p.92). The database management system that I have decided to write about is MySQL. SQL stands for structured query language which “asks users to write lines of code to answer questions against a database” (Baltzan, 2015, p.92). The company that makes and distributes the system is Oracle Corporation. Oracle Corporation is a worldwide computer technology corporation that was founded on July 16, 1977 in Santa Clara, California by Larry Ellison, Bob Miner, and Ed Oates. The headquarters are located in Redwood City, California and focuses on increasing and selling computer hardware systems and enterprise software products but mostly its own brands of database management systems. Oracle also builds tools for database development and systems of middle-tier software, enterprise resource planning (ERP) software, customer relationship management (CRM) software, and supply chain management (SCM) software. In this article “DBA and Developer Guide to MySQL 5.6”, talks about the new development of MySQL on how it is much better and that it has improved and just explaining more about its improvement. It has better performance and scalability, better application availability with online DDL/Schema, and better developer agility with NoSQL Access with Memcached API to InnoDB. It has improved in replication for high performance, self-healing,...

...Hibernate allows us to do object relational mapping. Simply this mean, conversion of objects derived from java classes inside the application, directly to tables in the database. This will reduce the effort utilized in drawing ER diagrams, normalization (conceptual design) as well as physically writing SQL coding to complete the physical design inside the RDBMS. Hibernate will prevent getting your java code dirty via writing SQL within it. If you use hibernate, no sql within your java application at all. Also hibernate provides:- • Caching of frequently used data record. Its several times efficient than retrieving from the database. • Needn’t opening and closing database connections. This will prevent memory leakage problems • Allow the java application to work with multiple DBMSes. • Small change in the java code will alter the table in the DB. Needn’t dropping the table. • 80% of code reduction in the application program When the required operation was initiated from the application, hibernate is versatile enough to auto generate the required SQL coding Go to this site called www.hibernate.org/downloads After going into the site .. notice some changes Look at the release bundles .. under the release bundle , download the latest version Add those into the library.. all those jar files to the library And then add a xml file and name as hibernate.cfg And then go to project file and search for a file in the name of hibernate.cfg.xml And from that get the...

...beneficial to switch to a more relational database like Microsoft Access. In turn, this will help improve internal communication and help streamline some of the work processes for the sales department. Currently the Party Plates Company uses Microsoft Excel to track personnel data in a spreadsheet inputting small amounts of repetitious data each time a record is created. Although Microsoft Excel and Microsoft Access offer some of the same tools such as applying filters, sorting table data, and extracting information, Microsoft Access a relational database, has features to track actions and events in multiple related tables. It offers more built in tools better to organize, track, and to make a relational structure between the tables by using a common field for the purpose of creating queries, forms, and reports large amounts of data than Microsoft Excel. The Party Plates Company would benefit from the use of converting their personnel data from single Microsoft Excel spreadsheets into a relational database, such as Microsoft Access (2012 Microsoft Corporation). There are many benefits that Party Plates would get from using Microsoft Access. The cost is reasonable to the other databases available; this system permits customization of databases making it possible to manage other functions together in the same area and not have to use more than one database. Microsoft Access prevents the duplication of the same information entered into the database. This will help save time entering...
