This book ramps up your skills in fast-paced but pragmatic fashion. After describing the subset of the SQL language that Pocket PC developers need to know, the author guides you through Microsoft's ADOCE and ActiveSync technologies with no-nonsense examples. Tiffany effectively shares his "been there, done that" experience to help programmers avoid the shoals can sink efforts to build Pocket PC applications that communicate with either local Pocket Access databases or remote SQL Server databases.
