Asna has documentation claiming that their speed surpasses that of ADO, however, Asna does not support SQL and to me that is a huge disadvantage, creating very messy code when accessing multiple tables that could be easily handled in a join statement.
I have looked around on IBM's site and it acknowledge that SQL is an industry standard and that future enhancements to DB2 will be geared towards SQL use, as opposed to native access. Can you give any insight on which method should be used? Is there a faster alternative to ADO that allows the use of SQL?
There are many iSeries customers & software vendors that are successfully using SQL as their data access interface in their applications. The key is to make sure the application and database are properly designed, optimized, and tuned for performance. We highly recommend that new SQL users attend the DB2 Performance Workshop to get educated on the SQL best practices. Portions of this workshop can be found online here.
