Additional Book Details
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.
