WTF? A B-Tree is a physical artifact! It stores data on disk. It has to support more than one reader / write at the same time, while still providing the operations.

How can you NOT talk about physical things - data stuctures, algorithms, bits, bytes etc - and still have anything relevant to say about "how to implement a DBMS"? Received on Fri Dec 08 2006 - 19:01:54 CST
