M20773 Analyzing Big Data with Microsoft R

The main purpose of the course is to give students the ability to use Microsoft R Server to create and run an analysis on a large dataset, and show how to utilize it in Big Data environments, such as a Hadoop or Spark cluster, or a SQL Server database.

Audience profile

  •   The primary audience for this course is people who wish to analyze large datasets within a big data environment.
  •   The secondary audience are developers who need to integrate R analyses into their solutions.

Learning Objectives

After completing this course, students will be able to:

  •   Explain how Microsoft R Server and Microsoft R Client work
  •   Use R Client with R Server to explore big data held in different data stores
  •   Visualize data by using graphs and plots
  •   Transform and clean big data sets
  •   Implement options for splitting analysis jobs into parallel tasks
  •   Build and evaluate regression models generated from big data
  •   Create, score, and deploy partitioning models generated from big data
  •   Use R in the SQL Server and Hadoop environments

Pre-Requisites

In addition to their professional experience, students who attend this course should have:

  •   Programming experience using R, and familiarity with common R packages
  •   Knowledge of common statistical methods and data analysis best practices.
  •   Basic knowledge of the Microsoft Windows operating system and its core functionality.
  •   Working knowledge of relational databases.
