Abstract
The Lucene Server project is an attempt to extend the Jakarta Lucene tool with server capabilities.
Lucene is a robust Java API that enables you creating indexes from text sources and perform powerful searches on these indexes. With Lucene, creating an index must be done programmatically and there are almost no possibilities of integrating index management in a distributed environment. In other words, out of the box, Lucene is suitable for integrating indexing and searching possibilities in a single application but not for providing index/search services for multiple applications.
The Lucene Server project comes with a Java API that propose the following
make it easy to create indexes in a declarative way by simply providing an XML configuration document.
make it easy to personalize the way Lucene must handle different kind of data sources.
provide services for index management and searching that can be accessed from several applications.
enable batch tasks scheduling.
Description: Microsoft?Windows?HTTP Services (WinHTTP) provides developers with a server-supported, high-level interface to the HTTP/1.1 Internet protocol. WinHTTP is designed to be used primarily in server-based scenarios by server applications that communicate with HTTP servers. WinHTTP
is also designed for use in system services and HTTP-based client applications. WinHTTP is more secure and robust than WinInet. However, single-user applications that need FTP or gopher functionality, cookie persistence, caching, automatic credential dialog handling, Internet Explorer compatibility, or downlevel platform support should still consider
using WinInet.
Portable, battery-powered operation of electronic apparatushas become increasingly desirable. Medical, remotedata acquisition, power monitoring and other applicationsare good candidates for battery operation. In some circumstances,due to space, power or reliability considerations,it is preferable to operate the circuitry from a single 1.5Vcell. Unfortunately, a 1.5V supply eliminates almost alllinear ICs as design candidates. In fact, the LM10 opamp-reference and the LT®1017/LT1018 comparators arethe only IC gain blocks fully specifi ed for 1.5V operation.Further complications are presented by the 600mV dropof silicon transistors and diodes. This limitation consumesa substantial portion of available supply range, makingcircuit design diffi cult. Additionally, any circuit designedfor 1.5V operation must function at end-of-life batteryvoltage, typically 1.3V. (See Box Section, “Componentsfor 1.5V Operation.”)

SQL是英文Structured Query Language的縮寫，意思為結構化查詢語言。SQL Server 2008在企業(yè)中也是非常重要的應用,各種財務系統(tǒng),erp系統(tǒng),oa系統(tǒng)等都會用到SQL Server 2008數(shù)據(jù)庫,甚至網站也可以用到數(shù)據(jù)庫來作為網站的后臺,SQL語句可以用來執(zhí)行各種各樣的操作，例如更新數(shù)據(jù)庫中的數(shù)據(jù)，從數(shù)據(jù)庫中提取數(shù)據(jù)等。目前，絕大多數(shù)流行的關系型數(shù)據(jù)庫管理系統(tǒng)，如Oracle, Sybase, Microsoft SQL Server, Access等都采用了SQL語言標準。
SQL Server 2008是一個重大的產品版本，它推出了許多新的特性和關鍵的改進，使得它成為至今為止的最強大和最全面的SQL Server版本。
SQL Server 2008新功能
這個平臺有以下特點
1、可信任的——使得公司可以以很高的安全性、可靠性和可擴展性來運行他們最關鍵任務的應用程序。
2、高效的——使得公司可以降低開發(fā)和管理他們的數(shù)據(jù)基礎設施的時間和成本。
3、智能的——提供了一個全面的平臺，可以在你的用戶需要的時候給他發(fā)送觀察和信息。
一、可信任的
在過去的Microsoft SQL Server 2005的基礎之上，Microsoft SQL Server 2008做了以下方面的增強來擴展它的安全性：
1、簡單的數(shù)據(jù)加密
Microsoft SQL Server 2008可以對整個數(shù)據(jù)庫、數(shù)據(jù)文件和日志文件進行加密，而不需要改動應用程序。進行加密使公司可以滿足遵守規(guī)范和及其關注 microsoft sql server
數(shù)據(jù)隱私的要求。簡單的數(shù)據(jù)加密的好處包括使用任何范圍或模糊查詢搜索加密的數(shù)據(jù)、加強數(shù)據(jù)安全性以防止未授權的用戶訪問、還有數(shù)據(jù)加密。這些可以在不改變已有的應用程序的情況下進行。
2、外鍵管理
Microsoft SQL Server 2008為加密和密鑰管理提供了一個全面的解決方案。為了滿足不斷發(fā)展的對數(shù)據(jù)中心的信息的更強安全性的需求，公司投資給供應商來管理公司內的安全密鑰。Microsoft SQL Server 2008通過支持第三方密鑰管理和硬件安全模塊（HSM）產品為這個需求提供了很好的支持。
3、增強了審查
Microsoft SQL Server 2008使你可以審查你的數(shù)據(jù)的操作，從而提高了遵從性和安全性。審查不只包括對數(shù)據(jù)修改的所有信息，還包括關于什么時候對數(shù)據(jù)進行讀取的信息。Microsoft SQL Server 2008具有像服務器中加強的審查的配置和管理這樣的功能，這使得公司可以滿足各種規(guī)范需求。Microsoft SQL Server 2008還可以定義每一個數(shù)據(jù)庫的審查規(guī)范，所以審查配置可以為每一個數(shù)據(jù)庫作單獨的制定。為指定對象作審查配置使審查的執(zhí)行性能更好，配置的靈活性也更高。
二、確保業(yè)務可持續(xù)性
1、改進了數(shù)據(jù)庫鏡像
Microsoft SQL Server 2008基于Microsoft SQL Server 2005，并提供了更可靠的加強了數(shù)據(jù)庫鏡像的平臺。新的特性包括：
2、頁面自動修復。Microsoft SQL Server 2008通過請求獲得一個從鏡像合作機器上得到的出錯頁面的重新拷貝，使主要的和鏡像的計算機可以透明的修復數(shù)據(jù)頁面上的823和824錯誤。
3、提高了性能。Microsoft SQL Server 2008壓縮了輸出的日志流，以便使數(shù)據(jù)庫鏡像所要求的網絡帶寬達到最小。
