MOC 20773 - 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.

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.

Goals
  1. Learn to explain how Microsoft R Server and Microsoft R Client work.
  2. Learn to use R Client with R Server to explore big data held in different data stores.
  3. Learn to visualize data by using graphs and plots.
  4. Learn to transform and clean big data sets.
  5. Learn to implement options for splitting analysis jobs into parallel tasks .
  6. Learn to build and evaluate regression models generated from big data .
  7. Learn to create, score, and deploy partitioning models generated from big data.
  8. Learn to use R in the SQL Server and Hadoop environments.
