The enormous legacy of EDW experience and best practices can be adapted to the unique capabilities of the Hadoop environment. In this webinar, in a point-counterpoint format, Dr. Kimball will describe standard data warehouse best practices including the identification of dimensions and facts, managing primary keys, and handling slowly changing dimensions (SCDs) and conformed dimensions. Eli Collins, Chief Technologist at Cloudera, will describe how each of these practices actually can be implemented in Hadoop.
Since the mid-1980s, Ralph has been the DW/BI industry’s thought leader on the dimensional approach and trained more than 20,000 students. Prior to working at Metaphor and founding Red Brick Systems, Ralph co-invented the first commercially-available workstation with a graphical user interface at Xerox’s Palo Alto Research Center (PARC). Ralph has his Ph.D. in Electrical Engineering from Stanford University.
