I am often asked usually by programmers - What is Data Warehousing & how do I learn it? I explain to them we use all the same tools that you do but differently. That’s when I coined the term Data Sense. It describes the essence of Data Warehousing and separates Data Warehousing from rest of Programming. Every aspect of IT from Hardware / Software infrastructure to Design, Development and QA is done with massive data flows and need for data precession accuracy and meaning.
