The best option is probably the ODBC API, although I have not worked
very much with it myself.

The other alternative is OLE DB, which you can do in three different
ways:

o The naked OLE DB API: leads to very verbose and repetive code. As crazy
as it may sound, this is my choice. (But what implement is an API,
so it makes sense.)

o The OLE DB Consumer Templates. These are some classes that wraps the
naked API into something which probably is less unwieldy to work with.

o ADO. While ADO is a high-level interface built on top of OLE DB,
it somehow manages to pick the worst out of OLE DB, and performs
a whole lot things behind your back.

You can find sample code for ODBC and OLE DB on
http://www.codeplex.com/MSFTEngProdSamples/. I once used these samples
for OLE DB to get started, and I found them very useful.
