This tutorial illustrates using the RDS programming model to query and update a data source. First, it describes the steps necessary to accomplish this task. Then the tutorial is repeated in Microsoft® Visual Basic Scripting Edition and Microsoft® Visual J++®, featuring ADO for Windows Foundation Classes (ADO/WFC).
This tutorial is coded in different languages for two reasons:
The documentation for RDS assumes the reader codes in Visual Basic. This makes the documentation convenient for Visual Basic programmers, but less useful for programmers who use other languages.
If you are uncertain about a particular RDS feature and you know a little of another language, you might be able to resolve your question by looking for the same feature expressed in another language.
从上边的说法看来，别的语言还是可以的！but less useful for programmers who use other languages.
