个人观点，PB会在浴火中重生。

开放数据库连接（Open Database Connectivity，ODBC）是为解决异构数据库间的数据共享而产生的，现已成为WOSA(The Windows Open System Architecture ),Windows开放系统体系结构)的主要部分和基于Windows环境的一种数据库访问接口标准ODBC 为异构数据库访问提供统一接口，允许应用程序以SQL 为数据存取标准，存取不同DBMS管理的数据；使应用程序直接操纵DB中的数据，免除随DB的改变而改变。用ODBC 可以访问各类计算机上的DB文件，甚至访问如Excel 表和ASCI I数据文件这类非数据库对象。

c# 连接数据库，详细过程.. Microsoft describe .NET in the following way: ".NET is the Microsoft Web services strategy to connect information, people, systems, and devices through software. Integrated across the Microsoft platform, .NET technology provides the ability to quickly build, deploy, manage, and use connected, security-enhanced solutions with Web services. .NET-connected solutions enable businesses to integrate their systems more rapidly and in a more agile manner and help them realize the promise of information anytime, anywhere, on any device." For more details about the entire framework, consult the FAQ Microsoft provide at: http://www.microsoft.com/net/basics_faq.mspx

This book, Data Manipulation with R, is aimed at giving intermediate-to-advanced level users of R (who have knowledge about datasets) an opportunity to use state-of-the-art approaches in data manipulation. This book will discuss the types of data that can be handled using R and different types of operations for those data types. Upon reading this book, you will be able to efficiently manage and check the validity of your datasets with the effective use of R programming, including specialized packages for data management. You will come to know about the split-apply-combine strategy, which is a state-of-the-art approach in data management. You will also come to know the way to work with database software through ODBC with the help of very simple examples. This book ends with an introduction to text processing for text mining using R.

DAY 1 Become familiar with the Visual C++ development envi- ronment by building a simple application. DAY 2 Learn about the stan- dard controls used in Windows applica- tions, how you can place and configure them on an applica- tion window, and how you can interact with them. DAY 3 Learn how you can capture mouse and keyboard events and react to them in your applications. DAY 4 Learn how to work with timers in a Visual C++ applica- tion. Learn how to have two or more timers running at the same time and how you can tell them apart. DAY 5 Learn how you can use some built-in dialogs to ask the user simple questions and how you can build your own cus- tom dialogs to get more detailed infor- mation from the user. DAY 6 Learn how to create menus to add to your application. DAY 7 Learn about the font infrastructure in Windows and how you can access it in your Visual C++ applications. DAY 8 Learn how to draw graphics in a Windows appli- cation. DAY 9 Learn how easy it is to incorporate ActiveX controls into your applications. DAY 10 Learn how to build a basic Single Document Interface (SDI) application and how to use the Document/View architecture. DAY 11 Learn how you can build Multiple Document Interface (MDI) applications. DAY 12 Learn how you can create and modify your own toolbars and status bars. DAY 13 Learn how you can use the structure pro- vided for you by the Document/View architecture to save and restore the data created in your appli- cation. DAY 14 Learn how easy it is to build a database application using an ODBC database. DAY 15 Learn about Microsoft’s latest database access tech- nology, ActiveX Data Objects (ADO), and how you can incor- porate it into your Visual C++ appli- cations. DAY 16 Learn how to build your functionality into library modules that you can give to other Visual C++ programmers for use in their applications. DAY 17 Learn how to build two different types of DLLs. DAY 18 Learn how you can enable your applica- tions to work on two or more separate tasks at the same time. DAY 19 Learn how you can build your own ActiveX controls that can be used in other applications or even in Web pages. DAY 20 Learn how Internet applications commu- nicate with each other using the Winsock interface and how you can make your applica- tions communicate over a network. DAY 21 See how easy it is to incorporate the Microsoft Internet Explorer Web browser into your own Visual C++ application.
