Campaign supports the ability to work with data stored in either delimited ASCII flat files or fixed-width ASCII flat files with a data dictionary. You can map flat files as base tables and access them from within a flowchart; you cannot map flat files as dimension tables.

Direct access to flat files removes the need to first upload data into a database to use with Campaign. This is useful for data exported from third-party applications (such as Excel or SAS) and for transient, one-time use data (such as a campaign-specific seed list, last-minute suppressions, predictive model scores, and other uses).
