Data type reference overview

Data Integration uses the following data types in synchronization tasks, mappings, mapping tasks, and replication tasks with Microsoft SQL Server:
Microsoft SQL Server native data types
Microsoft SQL Server 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.
