The requested URL /blogs/sherman/archives/2009/11/We are creatures of habit. Itâs not easy to stop doing something the way weâve always done it. Especially when we think we are right (but actually weâre not). Letâs explain. I have discussed (some might say preached) in many posts, articles, webinars, podcasts, classes and client discussions that for any recurring data integration tasks IT should use an Extract, Transform and Load (ETL) tool. This certainly has been the best practice for enterprise data warehousing projects in the Fortune 1000. This is where I got my early experience in data integration and got to use the ETL tools that annually rank in Gartnerâs Upper Magic Quadrant and Forresterâs Top Wave. These ETL tools enabled IT groups and SI (system integrator) project teams to tackle data integration challenges too complex and extensive for hand-coding. was not found on this server.
