Big Data Analytics with SAS

Overview of this book

SAS has been recognized by Money Magazine and Payscale as one of the top business skills to learn in order to advance one’s career. Through innovative data management, analytics, and business intelligence software and services, SAS helps customers solve their business problems by allowing them to make better decisions faster. This book introduces the reader to the SAS and how they can use SAS to perform efficient analysis on any size data, including Big Data. The reader will learn how to prepare data for analysis, perform predictive, forecasting, and optimization analysis and then deploy or report on the results of these analyses. While performing the coding examples within this book the reader will learn how to use the web browser based SAS Studio and iPython Jupyter Notebook interfaces for working with SAS. Finally, the reader will learn how SAS’s architecture is engineered and designed to scale up and/or out and be combined with the open source offerings such as Hadoop, Python, and R. By the end of this book, you will be able to clearly understand how you can efficiently analyze Big Data using SAS.

The DS2 programming language


As described in  SAS® 9.4 Programming Documentation / DS2 Reference - What is DS2(http://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.2&docsetId=ds2ref&docsetTarget=p0qrslgyjx5ti6n), The DS2 language shares core features with the DATA step. However, DS2's capabilities extend far beyond those of the DATA step. DS2 is a procedural language that has variables, scope, methods, packages, control flow statements, table I/O statements, and parallel programming statements. Methods and packages give DS2 modularity and data encapsulation. DS2 enables you to insert SQL directly into the SET statement, thus blending the power of two powerful data manipulation languages.

DS2 intersects with the SAS data step; however, it supports much more than character and numeric datatypes. DS2 supports the following datatypes: BIGINT, BINARY(n), CHAR(n), DATE, DECIMAL|NUMERIC(p,s), DOUBLE, FLOAT, INTEGER, NCHAR(n), NVARCHAR(n), REAL, SMALLINT, TIME(p), TIMESTAMP...
