DataFactory supports the following database types: DB2, SQL Server, Oracle, and Sybase, And the ODBC data source. This document uses ODBC as an example to describe. Before generating data, you must first set the system ODBC data source, that is, add the data source to be operated (Start> Control Panel> Management Tools> ODBC data source ). For simplicity, create an Access database DataFactory.
