Kevin, you can't post commercial links like that. The OP asked about SQL database "tools" for iPad. ODBC stands for "Open Database Connectivity", it's an industry standard for connecting devices like iPad to all revisions of all brands of SQL-type databases and SDK stands for Software Development Kit. Thus, all the OP has to do is web search for "iPad ODBC SDK".
