Rather than wait for the end-user community to react to market changes, Oracle took a proactive approach and often introduced features far-ahead of the market demand. I remember when Oracle 7 was undergoing beta testing and we wondered about the new “cost based optimizer,” “hash joins,” and bitmap indexes. In Oracle 8, we replaced EBU with RMAN and learned about partitioning and star transformations. And so on-high anticipation with every release.
