Overview of this book

<p>Big data analytics is the process of examining large amounts of data of a variety of types to uncover hidden patterns, unknown correlations, and other useful information. Such information can provide competitive advantages over rival organizations and result in business benefits, such as more effective marketing and increased revenue. New methods of working with big data, such as Hadoop and MapReduce, offer alternatives to traditional data warehousing. <br /><br />Big Data Analytics with R and Hadoop is focused on the techniques of integrating R and Hadoop by various tools such as RHIPE and RHadoop. A powerful data analytics engine can be built, which can process analytics algorithms over a large scale dataset in a scalable manner. This can be implemented through data analytics operations of R, MapReduce, and HDFS of Hadoop.<br /><br />You will start with the installation and configuration of R and Hadoop. Next, you will discover information on various practical data analytics examples with R and Hadoop. Finally, you will learn how to import/export from various data sources to R. Big Data Analytics with R and Hadoop will also give you an easy understanding of the R and Hadoop connectors RHIPE, RHadoop, and Hadoop streaming.</p>

Understanding MongoDB


MongoDB is a NoSQL-based distributed document data storage. This has been specially designed for providing scalable and high performance data storage solutions. In many scenarios, it can be used to replace traditional relational database or key/value data storage. The biggest feature of Mongo is its query language, which is very powerful, and its syntax is somewhat similar to object-oriented query language.

The following are the features of MongoDB:

  • Set-oriented storage and easy to store the object type

  • Support for dynamic queries

  • Full index support

  • Rich query language

  • Data fragments processing order to support the expansion of the cloud level

  • BSON-based file data storage

  • Supported with C, C++, C#, Erlang, Haskell, Java, JavaScript, Perl, PHP, Python, Ruby, and Scala

We can use R and MongoDB together by installing the following prerequisites:

  • MongoDB installation

  • rmongodb installation
