The Microsoft SQL Server data provider offers direct access to Microsoft SQL Server data stores and only SQL Server data stores (version 7.0 and greater). The System.Data.SqlClient namespace contains the types used by the SQL Server provider and offers the same basic functionality as the OLE DB provider. The key difference is that the SQL Server provider bypasses the OLE DB layer and gives numerous performance benefits. The Microsoft SQL Server data provider also allows you to gain access to the unique features of this particular DBMS. The remaining Microsoft-supplied providers (System.Data.Odbc and System.Data.SqlClientCe) provide access to ODBC connections, and the SQL Server Mobile edition DBMS (commonly used by handheld devices, such as Windows Mobile). The ODBC types defined within the System.Data.Odbc namespace are typically only useful if you need to communicate with a given DBMS for which there is no custom .NET data provider. This is true because ODBC is a widespread model that provides access to a number of data stores.

Once you ve installed the certificate, it s fairly easy to use SSL communication. The only other step is to modify your request to use a URL that starts with https:// instead of the http:// prefix. Typically, this means tweaking a Response.Redirect() statement in your code. Because all the encryption and decryption occurs just before the message is sent (or immediately after it is retrieved), your application does not need to worry about deciphering the data manually, manipulating byte arrays, using the proper character encoding, and so on. At the server side, you can also enforce SSL connections so that it is impossible to interact with a web service without encrypting communication. Simply right-click the website in IIS Manager, and select the Directory Security tab. In the Secure Communications section, click the Edit button (which is available only after a certificate is installed). Then, choose Require Secure Channel (see Figure 19-8).

Earlier versions of the .NET platform shipped with an assembly named System.Data.OracleClient.dll, which as the name suggests, offered a data provider to communicate with Oracle databases. As of .NET 4.0, however, this assembly has been marked as obsolete and will eventually be deprecated. At first glance, this might cause you to fear that ADO.NET is slowly becoming focused squarely on Microsoft-centric data stores; however, this is not the case. Oracle provides its own custom .NET assembly, which follows the same overall design guidelines as the data providers provided by Microsoft.

Keep in mind that there are good reasons not to enforce an SSL connection for an entire virtual directory. For example, you might want to secure some method calls in a web service but not secure others that don t return sensitive information. This allows you to increase performance and reduce the work performed by the server. If needed, you can check for a secure connection in your code and then throw an exception or redirect the user if SSL is required but not present. Here s an example that checks whether the current request is transmitted over a secure connection using the HttpRequest.IsSecureConnection property: If Request.IsSecureConnection Then ' (Application code goes here.) Else ' Redirect with https to ensure the page is accessed over SSL. Response.Redirect("https://www.mySite.com/account.asmx") End If

If you need to obtain this .NET assembly, you can visit the downloads section of Oracle s web site at www.oracle.com/technology/tech/windows/odpnet/index.html.

In addition to the data providers that ship from Microsoft (as well as Oracle s custom .NET library), numerous third-party data providers exist for various open source and commercial databases. While you will most likely be able to obtain an ADO.NET data provider directly from the database vendor, you should be aware of the following site: www.sqlsummit.com/DataProv.htm. This web site is one of many sites that document each known ADO.NET data provider and provide links for more information and downloads. Here you will find numerous ADO.NET providers, including SQLite, IBM DB2, MySQL, PostgreSQL, TurboDB, Sybase, and many others. Given the large number of ADO.NET data providers, the examples in this book will use the Microsoft SQL Server data provider (System.Data.SqlClient.dll). Recall that this provider allows you to communicate with Microsoft SQL Server version 7.0 and higher, including SQL Server Express Edition. If you intend to use ADO.NET to interact with another DBMS, you should have no problem doing so once you understand the material presented in the pages that follow.

A common mistake is to use localhost or any other aliases for the server host name in an SSL connection. This will not work, because the client attempts to verify that the CN (common name) part of the subject name of the server certificate matches the host name found in the HTTP request during the handshake portion of the SSL exchange.
