印刷電路板（PCB）設計解決方案市場和技術領軍企業Mentor Graphics（Mentor Graphics）宣布推出HyperLynx® PI（電源完整性）產品，滿足業內高端設計者對于高性能電子產品的需求。HyperLynx PI產品不僅提供簡單易學、操作便捷，又精確的分析，讓團隊成員能夠設計可行的電源供應系統；同時縮短設計周期，減少原型生成、重復制造，也相應降低產品成本。隨著當今各種高性能/高密度/高腳數集成電路的出現，傳輸系統的設計越來越需要工程師與布局設計人員的緊密合作，以確保能夠透過眾多PCB電源與接地結構，為IC提供純凈、充足的電力。配合先前推出的HyperLynx信號完整性（SI）分析和確認產品組件，Mentor Graphics目前為用戶提供的高性能電子產品設計堪稱業內最全面最具實用性的解決方案。“我們擁有非常高端的用戶，受到高性能集成電路多重電壓等級和電源要求的驅使，需要在一個單一的PCB中設計30余套電力供應結構。”Mentor Graphics副總裁兼系統設計事業部總經理Henry Potts表示。“上述結構的設計需要快速而準 確的直流壓降(DC Power drop)和電源雜訊(Power Noise)分析。擁有了精確的分析信息，電源與接地層結構和解藕電容數(de-coupling capacitor number)以及位置都可以決定，得以避免過于保守的設計和高昂的產品成本。”

MFC Black Book Introduction: Are you an MFC programmer? Good. There are two types of MFC programmers. What kind are you? The first kind are the good programmers who write programs that conform to the way MFC wants you to do things. The second bunch are wild-eyed anarchists who insist on getting things done their way. Me, I’m in the second group. If you are in the same boat (or would like to be) this book is for you. This book won’t teach you MFC—not in the traditional sense. You should pick it up with a good understanding of basic MFC programming and a desire to do things differently. This isn’t a Scribble tutorial (although I will review some fundamentals in the first chapter). You will learn how to wring every drop from your MFC programs. You’ll discover how to use, abuse, and abandon the document/view architecture. If you’ve ever wanted custom archives, you’ll find that, too.

SQL是英文Structured Query Language的縮寫，意思為結構化查詢語言。SQL語言的主要功能就是同各種數據庫建立聯系，進行溝通。按照ANSI(美國國家標準協會)的規定， SQL被作為關系型數據庫管理系統的標準語言。SQL語句可以用來執行各種各樣的操作，例如更新數據庫中的數據，從數據庫中提取數據等。目前，絕大多數流 行的關系型數據庫管理系統，如Oracle, Sybase, Microsoft SQL Server, Access等都采用了SQL語言標準。雖然很多數據庫都對SQL語句進行了再開發和擴展，但是包括Select, Insert, Update, Delete, Create, 以及drop在內的標準的SQL命令仍然可以被用來完成幾乎所有的數據庫操作。下面，我們就來詳細介紹一下SQL語言的基本知識。
