Data can be loaded into WCS tables using data load utility. WCS Data Load utility performs the following functions in a single operation: 1. Reads the data from the input source file. 2. Transforms the source data to Web Sphere Commerce business objects. 3. Allocates and resolves Web Sphere Commerce business objects to physical data. 4. Loads the physical data into the database. There are three configurations files and a input source file required to complete the data loader setup.

The three configuration files are listed below. 1. wc-dataload-env.xml 2. wc-dataload-loader.xml 3. wc-dataload.xml wc-dataload-env.xml holds the environment settings such as database name,
