Big Data Analytics with R

By: Simon Walkowiak

Overview of this book

Big Data analytics is the process of examining large and complex data sets that often exceed the computational capabilities. R is a leading programming language of data science, consisting of powerful functions to tackle all problems related to Big Data processing. The book will begin with a brief introduction to the Big Data world and its current industry standards. With introduction to the R language and presenting its development, structure, applications in real world, and its shortcomings. Book will progress towards revision of major R functions for data management and transformations. Readers will be introduce to Cloud based Big Data solutions (e.g. Amazon EC2 instances and Amazon RDS, Microsoft Azure and its HDInsight clusters) and also provide guidance on R connectivity with relational and non-relational databases such as MongoDB and HBase etc. It will further expand to include Big Data tools such as Apache Hadoop ecosystem, HDFS and MapReduce frameworks. Also other R compatible tools such as Apache Spark, its machine learning library Spark MLlib, as well as H2O.

Chapter 5. R with Relational Database Management Systems (RDBMSs)

We have already done quite a lot of Big Data analytics using the R language in the preceding chapters, but this book would not be complete if we didn't touch on the subject of databases. To be precise, in this chapter we will explore connectivity between R and very popular Relational Database Management Systems (RDBMSs), more commonly known as SQL databases. After reading the contents of this chapter, you will know how:

  • To set up a number of local and/or remote SQL databases, for example SQLite, PostgreSQL, and MariaDB/MySQL

  • To query and manage SQL databases directly from R (both locally and remotely) using a selection of R packages

  • To launch fully-managed, highly-scalable Amazon RDS database instances (of different types) and query their records using the R language

During the process of achieving the preceding goals, you will also be exposed to a variety of methods and techniques that will help you with the installation of specific...
