The SQLWizard Import Utility provides interactive and batch capabilities for transferring data from various formats into tables, including the DSNTIAUL format that can be generated from mainframe DB2 data. The DSNTIAUL format stores data in its internal DB2 representation, thus requiring little or no conversion before insertion into the database.
One additional feature is available in the Import Utility, to speed the processing of import data even more, called Direct Write. This option bypasses all referential integrity features normally imposed by the SQL engine and eliminates all engine overhead that would be encountered during normal record insertions. Instead, information is written directly to the table file. This method of data loading achieves maximum performance.
See the SQLWizard User's Guide for more about the Import Utility and the Direct Write Import feature.
