1. Quantum computing is more efficient than classical computing for all possible computations, meaning more results per unit work (the "something for nothing" myth).
2. Quantum computing exploits quantum parallelism in a way comparable to, but better than, classical parallelism (the "each n-qubit quantum state is 2 n classical bits" myth).
• The conceptual mismatch between scientific data and relational tables is of secondary importance to the data-mining performance and features the DBMS offers. Modern RDBMSs deliver both performance and features, whereas OODBMSs have not kept up with the demands of data-intensive science.
• The mismatch problem is not as bad as we had originally thought. As we described in our article, we were able to translate our object data to relational tables without too much trouble. We also added several stored procedures and functions to encode methods within the SQL database.
