Data Integration uses the following data types in Open Table mappings and mapping tasks:
Open Table native data types
: Open Table data types appear in the source and target transformations when you choose to edit metadata for the fields.
Transformation data types
: Set of data types that appear in the transformations. They are internal data types based on ANSI SQL-92 generic data types, which the Secure Agent uses to move data across platforms. Transformation data types appear in all transformations in a mapping.
When Data Integration reads source data, it converts the native data types to the comparable transformation data types before transforming the data. When Data Integration writes to a target, it converts the transformation data types to the comparable native data types.
