Even when they do not navigate relational databases, they absurdly conclude from a lack of adequate physical independence in many SQL databases that the solution to performance problems lies in no physical independence at all.

We never directly connected because Carl's motive is not to improve overall understanding of database management systems, but to sell a product as something it is not. Improved understanding of database management systems defeats his goal. Received on Sun Aug 19 2001 - 08:44:36 CEST
