1 Paper 244-31 Think FAST! Use Memory Tables ( hashing ) for Faster merging Gregg P. Snell, Data Savant Consulting, Shawnee, KS ABSTRACT The objective of this paper is to present a simple way to merge datasets using Memory Tables . Well, actually, it will be an associative array (or hash) object. However, by simply thinking of this object as an in- Memory table , it just may help you to grasp the hashing concepts and feel less intimidated about learning and using (what I believe is) the fastest method available for merging datasets. INTRODUCTION merging datasets is something we all do. Unfortunately, the bigger the files get and the more often you need to do it, the Faster you want the process to be.
