For developers who have experience working with relational databases, this may lead to misconceptions as to how SimpleDB works.This practical book aims to address your preconceptions on how SimpleDB will work for you. You will be quickly led through the differences between relational databases and SimpleDB, and the implications of using SimpleDB. Throughout this book, there is an emphasis on demonstrating key concepts with practical examples for Java, PHP, and Python developers.You will be introduced to this massively scalable schema-less key-value data store: what it is, how it works, and why it is such a game-changer. You will then explore the basic functionality offered by SimpleDB including querying, code samples, and a lot more. This book will help you deploy services outside the Amazon cloud and access them from any web host.You will see how SimpleDB gives you the freedom to focus on application development. As you work through this book you will be able to optimize the performance of your applications using parallel operations, caching with memcache, asynchronous operations, and more.

Experimenting with SimpleDB

As SimpleDB is so different, it helps to have a tool for manipulating and exploring the database. When developing with a MySQL database, phpMyAdmin allows the developer to work directly on the database. SimpleDB has a similar free Firefox plugin called sdbtool ( Another Firefox plugin used in the more advanced examples is S3Fox ( for administering the Amazon S3 storage. In this book, we cover several basic sample applications. We have also provided code to show each SimpleDB application using three languages: Java, PHP, and Python.

As access to SimpleDB can be from any site on the Web, the PHP samples can be downloaded and run directly from your site. To run any sample, an Amazon account is required. These samples let you explore most of the SimpleDB API, as well as some of the S3 API capabilities.

You can both download and try the PHP samples from
