In the 1950s and '60s, those shiny 45-rpm records with the big hole in the middle were the primary delivery system for popular American music, especially rock 'n' roll. Cheap to manufacture and available to even fly-by-night record operations, the “donut disc” changed the way popular music was written, recorded, promoted and marketed, and it broke – at least for a time – the iron-fisted dominance of the major record corporations. This book traces the 7-inch single's origins back to the 1880s, and explains the personality conflicts that led an eccentric genius to develop the 45 into one of postwar America's most popular consumer products. It explores how the jukebox, the autonomous disc jockey, and payola and artist rip-offs kept the 45 at the forefront of rock for 20 years. There are also chapters on the most valuable (and legendary) 45s of all time, as well as the oddities, oddballs and freak hits that make listening to 45s so much fun. With over 80 illustrations – many in full color.

Learning good map design techniques for BizTalk Server will make a huge difference to the processing speed of your implementation, as well as to the scalability and maintainability of your code. Regardless of your experience, expert authors Jim Dawson and John Wainwright ensure you make the right choices to reap the rewards and avoid the potential penalties of poor design.Pro Mapping in BizTalk Server 2009 provides in–depth coverage of all aspects of mapping to enable you to quickly and efficiently incorporate logic that will fulfill your mapping requirements. While the mapping techniques will be useful for all versions of BizTalk Server, the code is tailored toward BizTalk Server 2006 R3 and demonstrates the latest approaches to standard maps, electronic data interchange, and RFID components. You'll refer again and again to the multiple solutions that will help solve your new mapping challenges, and soon find this is an essential reference for any BizTalk implementation.
