Data Reader Configuration

This section defines the data reader to use, the location of the input file, and any parameters. You can define a custom data reader to read data into the Bulk Matcher if you are not using the data file output by the Data Cleanser or if your data is formatted differently than the default data reader requires. For more information about the default data reader's requirements, see Required Format for Flat Data Files. You define the custom reader in Java, and then specify the class and configure the reader using the elements and attributes in the following table. You only need to configure the data reader for the master IBML Tool.
