Book excerpt: The new FileMaker 12 allows you to build unparalleled databases for a wide variety of devices, from Windows and Mac desktops to iPhones and iPad. With 10 million registered customers, FileMaker's users are "average Joes" who are knowledge workers, subject matter experts, and business users from all walks of life. The community extends well beyond the pool of professional software developers. FileMaker's legendary ease-of-use has led to its wide adoption and has allowed non-programmers an avenue into creating sophisticated software solutions. FileMaker 12 Developer’s Reference will serve to help bridge the gaps in these people's understanding of FileMaker's hundreds of calculation functions, script steps, and operations. They know FileMaker, they've used it for years, but they need a quick reference, immediately accessible while not interrupting their work on screen. There is no other book like this on the market. All FileMaker books include information on calculation formulas, scripting, etc., but none have expressly focused on giving readers one simple thing: a quick reference to be used in conjunction with their programming efforts. Some books teach, others explain, still others explore specific in-depth topics. This book will appeal to the entire FileMaker Pro community and be a great extension of their library. This edition is updated for the many new features coming with FileMaker 12, including the product's design functionality and the file format, and a new section dedicated to FileMaker Go, which is the iOS client.
