Programmability

The ADO.NET model uses typed programming to manipulate objects. In typed

programming, the programming environment or programming language itself recognizes

the types of things that are important to users. To take full advantage of typed

programming, you must know the things that are of interest to programmers and to end

users. Consider the following code using typed programming in ADO.NET:

If TotalQty > DataSet1.ProductInfo("Baby Food").QtyAvailable

This code is equivalent to a line using non-typed programming and is easier to read by

end users. An end user who has little or no programming experience can easily grasp

the meaning of the condition being tested. Also, in non-typed programming, if the

developer makes a spelling mistake by chance (for example, ProductInfo is spelled as

ProdcutInfo), a run-time error will get generated. On the other hand, in typed datasets,

errors in the syntax caused by misspellings are detected at compile time rather than at

run time.
