SQL Server Integration Services data typing

- SQL Server Integration Services Data Types…SSIS uses several different type systems…and depending on which type system we're using,…we may have to or probably…will have to, convert from one type over into another.…The different type systems:…the first is native or that is…the SQL Server data types.…That's built in…and unless within SQL…we're using CLR, the common language runtime,…or we've got some kind of a custom type…that we built, then the SQL server data types…are the ones that we will be dealing with…when working over in SQL.…

However,…in Integration Services we have the variable data types…and that's when go in and create…a variable.…Those data types are dependent on the underlying…type systems and that is exposed…in the .net framework data types.…However, not all .net framework data types…can be used in SSIS.…We have the pipeline buffer data types.…

The pipeline buffer means…when we're actually now into the data flow…and we're doing an ETL,…so we're moving data from point A…over to point B.…And the data types available in the pipeline buffer…
