SCWCD考古題免費下載

   最近常看見朋友為SCWCD考試問題愁眉苦臉,長噓短嘆。其實做任何事情只需要擺正好心態,一切問題都會OK。SUN認證中,除了SCJP認證外,還有SCWCD認證比較熱門。SCJP是考取SUN證照的基礎,是考取其他認證的敲門磚。你想考SCWCD,就必須要擁有SCJP認證。SCJP認證的官方考試編號:310-065/310-055,在報考時,你可以根據自己的能力選擇考試語言。語言:繁體/English/日文。朋友大都數都是報考英文,英文是全球通用的語言,具有一定的權威性。SUN認證主攻方向:程式語言。

SCWCD考試科目:310-083 ,如今我也搜集了一些關于SUN考古題資料,在網站中找了很多家題庫網站,個人認為:310-065繁體版本的題庫只有KillTest考古題網(www.killtest.net)這家還不錯,而且朋友也經常去光顧。主要是切身為客戶著想了,這是朋友和我一次談話中提及的,他們每門題庫的覆蓋率都比較高,通過率那自然而然的成正比了。而且他們會給客戶適當的折扣優惠。目前推出會員折扣號的活動,切實做到一切以客戶為上帝的原則,朋友信賴KillTest考古題,那一定沒錯的,,產品不僅特美價廉,口碑更值得信賴!

  答:1)ODBC(OpenDatabaseConnectivity)
  壹個以C語言為基礎訪問SQL為基礎數據庫引擎的接口,它提供了壹致的接口用於和數據庫溝通以及訪問數據。
  2)JDBC
  Java版本的ODBC
  JDBC基礎2.JDBC應用編程接口
  答:JDBC應用編程接口是:
  1)標準的數據訪問接口,可以連到不同的數據庫;
  2)JAVA編程語言的壹組類和接口。
  JDBC應用編程接口能夠:
  1)連接到數據庫;
  2)發SQL查詢字符串到數據庫;
  3)處理結果。
  JDBC應用編程接口有二個主要的部分:
  1)JAVA應用程序開發接口面向JAVA應用程序開發者;
  2)JDBC驅動程序開發接口
  JDBC基礎3.JDBCDriver
  答:1)壹大堆實現了JDBC類和接口的類;
  2)提供了壹個實現java.sql.Driver接口的類。
  JDBC基礎4.JDBCDriver的四種類型
  答:1)JDBC-ODBC橋
  由ODBC驅動提供JDBC訪問
  2)本地API
  部分Javadriver把JDBC調用轉化成本地的客戶端API
  3)JDBC-net
  純的Javadriver,將JDBC調用轉入DBMS,與網絡協議無關。然後通過服務器將調用轉為DBMS協議。
  4)本地協議
  純的javadriver,將JDBC調用直接轉為DBMS使用的網絡協議

The News about MySQL Database Integration

Added Support for JavaScript Programming Language Extends Productivity for the Creation of Next Generation Web Applications.SANTA CLARA, CA March 17, 2008 Sun Microsystems, Inc. (Nasdaq: JAVA), the leading Open Source company, and the NetBeans community today announced the immediate availability of NetBeans 6.1 integrated development environment (IDE) Beta. NetBeans 6.1 Beta adds a rich set of features for JavaScript technology development, a key component for delivering Ajax web applications and tighter integration of MySQL database functionality. The NetBeans 6.1 IDE Beta is available now via download.

The JavaScript technology support is based on the dynamic language support added for Ruby and includes: semantic highlighting, code completion, type analysis, quick fixes, semantic checks and refactoring. It also includes a browser compatibility feature that makes it easy to create JavaScript software code that works in the popular Mozilla Firefox, Windows Internet Explorer, Opera, and Safari Web browsers. Sun’s commitment to dynamic languages has expanded with the recent hiring of Python and Jython developers, Ted Leung and Frank Wierzbicki, respectively. Leung and Wierzbicki join other technologists, such as Ian Murdock, Charles Nutter, Thomas Enebo, and Nick Kew who have recently joined Sun to pursue open source project development and community activities. “Since the release of NetBeans 4.0 IDE, momentum and adoption has been phenomenal with more than 9.3 million downloads during the past two years,” said Jim Parkinson, vice president of Tools and Services at Sun. “With NetBeans 6.1 IDE, we expect adoption rates to continue to go through the roof especially with the new JavaScript software functionality and the tighter integration work taking place with the MySQL database. This release of NetBeans IDE exemplifies the innovation and success of the open source initiatives at Sun.”

Other highlights of NetBeans 6.1 IDE Beta include:
Performance enhancements including faster startup and code completion;
Spring framework support with features such as configuration file support, code completion and hyperlinks to speed navigation;
New MySQL support in the Database Explorer to make it easier to create, launch and view MySQL databases;
Significant enhancements to the Ruby/JRuby support, including a new Ruby platform manager, support for the latest version of Rails and new hints and quick fixes in the editor;
Beta support for the ClearCase version control system- made available as a plugin from the Update Center.
Join the NetBeans software team on May 5, 2008 for the fifth annual NetBeans Day, now a track at the CommunityOne 2008 Conference being held the day before the JavaOne 2008 Conference. The NetBeans community track offers developers a chance to learn from the experts, find out firsthand what’s new and what’s coming in the NetBeans IDE and network with other members of the community.
