A flat file contains data and the format of data. Data format can be specified by a custom separator, a fixed length, or by columns that you define with a name and a data type.
A flat file can be linked to a transformation process via a data connection in order to model and document data transformations. For more information about data transformations, see Building Data Transformation Diagrams.
In the following example, FlatFile_CSV is linked to TransformationProcess via a data connection, which is turned linked to FlatFile_FixedLength via another data connection:
