Amazon SimpleDB Query Tutorials

In order to allow developers to gain a better understanding of the Amazon SimpleDB Query language, we have just posted a pair of tutorials:

In Query 101: Building Amazon SimpleDB Queries, you will learn about the basic principles of the language, including the comparison and set operators, and how to use them in simple and range queries. With that as a base, you will then learn about multi-valued queries, which (naturally enough) operate on SimpleDB attributes which have multiple values. Finally, you will learn about multi-predicate queries, using the union and intersection operators to ask more complex questions.

In Query 201: Tips & Tricks for Amazon SimpleDB Query, you will learn about lexicographic comparison, querying for numerical data and dates, using negation, tuning your queries using BoxUsage, partitioning your data for best query performance, and efficient retrieval of result sets.

Thanks for the tutorials, Jeff. While we've launched the new Beaa Mux with SimpleDB support, we are still trying to get our head around all the possibilities and gotchas of the service.
