You can run iWay Data Quality Center (DQC) in command line (batch) mode or online mode.

Command line mode is suitable for running one-time or periodic operations involving large amounts of data (such as cleansing, deduplication, and profiling). This section describes how to run iWay DQC in command line mode.

Online mode is suitable for operations that are executed whenever required by the user or business process (examples include validation of user input, identification, or incremental update of stored data). For information on online mode, see Using Online Services.
