傻瓜SAS可以帮助企业提高数据传输，分析，报告，数据预测，统计分析等。它提供统计和数据分析工具来帮助你处理各种资料，业务，财务等。
Unless you’re a hermit, chances are good that your life is touched by SAS (pronounced “sass”) almost every day. Have you ever received an offer for a credit card in the mail? The bank might have used SAS to select you for the particular offer you received. Remember a recent news article that cited demographic trends in the United States? The Census Bureau uses SAS to crunch its numbers. Were you tempted to buy that new gadget in a big-name retail store? The corporate office might have used SAS to calculate the best price to set for that specific item on that specific week. The rate you pay for life insurance, the analysis behind pharmaceutical drug trials, the quality of parts used to assemble your automobile — all these are determined by people who use SAS. You don’t see SAS directly from day to day — but, like gravity, it’s an invisible force that affects your life. This book offers a prolonged glimpse into the multifaceted world of SAS software.

内容摘要
《人件》第1版于 1987 年出版，专门讨论了软件开发和维护团队的管理问题，并向人们的传统认识提出了挑战。作者在书中推崇人本管理思想，正确指出知识型企业的核心是人，而不是技术，呼吁给予软件工作者充分的自由和信任。本书推出后，立即在西方引起了轰动，被誉为“几十年来对美国软件业影响最大的理念”。与《人月神话》一样，《人件》现已成为软件团队管理的经典之作。它和《人月神话》共同被誉为软件图书中“两朵最鲜艳的奇葩”。人们认为，《人月神话》关注“软件开发”本身，《人件》则关注软件开发中的“人”，因此，在成千上万的书架上，《人件》永远和《人月神话》并列在一起。1999 年 2 月，《人件》第2版出版，增补了8 章新内容。这些新内容拥有更加宽广的视角，对大中型组织中的团队如何运作进行了深入探讨。《人件》最新版的中文译本由UMLChina组织翻译，清华大学出版社将于2003 年5月出版。

After the introduction of this book immediately caused a sensation in the West, as the "Over the past decades the software industry in the United States the concept of the greatest impact." And "The Mythical Man-Month", the "people pieces of" software team management has become a classic. It and "The Mythical Man-Month" common software library known as the "wonderful work of the two most colorful."
