Most business applications run on relational databases (RDB) from companies like Oracle. There’s a view that RDB is an “old” technology which is true – it came about in 1970 so it’s not new. However, there have been decades of investment in RDB as a platform which makes it unrivaled when it comes to consistency, integration, performance, transaction processing, and reporting. RDB systems are good business and generate 40% operating margins. Companies like Oracle can afford to build and buy new technologies (like MySQL) and dominate the market . . .
