Win32 Database Interfaces
We have seen how Perl can be used to create and maintain databases. What we haven’t talked about is how Perl can also be used to access data stored in many popular database formats.
One of the handiest extension modules for Perl for Win32 is
Win32::ODBC
. Written by Dave Roth,
Win32::ODBC provides an interface to any ODBC data
source for which you have a driver.
A detailed discussion of Win32::ODBC is beyond the
scope of this book, but you can find Win32::ODBCat any CPAN site (try
http://www.perl.com/CPAN/authors/Dave_Roth/).
Another popular way to access data from Perl for Win32 is to use the OLE Automation interface to Microsoft’s ActiveX Data Objects (ADO). ADO is an OLE interface that provides uniform data access to any compliant data source (including ODBC). See Chapter 19, for a couple of examples of how to use ADO. For more information on ADO, see http://www.microsoft.com/ado.
