Mastering the SAS DS2 Procedure: Advanced Data-Wrangling Techniques, Second Edition (Hardcover edition)

Enhance your SAS data-wrangling skills with high-precision and

parallel data manipulation using the DS2 programming language.

Now in its second edition, this book addresses the DS2 programming language

from SAS, which combines the precise procedural power and control of the

Base SAS DATA step language with the simplicity and flexibility of SQL. DS2

provides simple, safe syntax for performing complex data transformations in

parallel and enables manipulation of native database data types at full

precision. It also covers PROC FEDSQL, a modernized SQL language that

blends perfectly with DS2. You will learn to harness the power of parallel

processing to speed up CPU-intensive computing processes in Base SAS and

how to achieve even more speed by processing DS2 programs on massively

parallel database systems. Techniques for leveraging internet APIs to

acquire data, avoiding large data movements when working with data from

disparate sources, and leveraging DS2's new data types for full-precision

numeric calculations are presented, with examples of why these techniques

are essential for the modern data wrangler.

Here's what's new in this edition:

•

how to significantly improve performance by using the new SAS

Viya architecture with its SAS Cloud Analytic Services (CAS)

how to declare private variables and methods in a package

the new PROC DSTODS2

the PCRXFIND and PCRXREPLACE packages

•

While working though the code samples provided with this book, you will

build a library of custom, reusable, and easily shareable DS2 program

modules, execute parallelized DATA step programs to speed up a

CPU-intensive process, and conduct advanced data transformations using hash

objects and matrix math operations.
