<p> </p><p><br/>The Complete Guide to SAS Indexes</p><p>--By Michael A. Raithel</p><p>--Publisher: SAS Publishing (January 27, 2006) </p><p>/***************************************************************************************/</p><p>It describes all the techniques to create indexes for <br/>SAS data sets (in a data step, in proc sql, in proc datasets), <br/>and gives lots of (short/useful) code examples. <br/><br/>It describes how to create &amp; use both "simple" and "composite" <br/>indexes, and tells you in very straightforward language when <br/>you might want to use each of them. <br/><br/>And for the more esoteric/hardcore reader, it even goes into <br/>how the indexes are actually implemented (as b-trees) under <br/>the covers (this would be optional-reading for most users :) <br/><br/>If you use large SAS data sets, and your queries take <br/>long enough that you find your self "waiting" on them, <br/>then you could probably benefit from adding Indexes to <br/>your large SAS data sets (tables). This book will be a <br/>big benefit to you. </p><p>/***************************************************************************************/<br/></p>
