Surrogate Key Transformation
Surrogate
Key is SSIS data flow transformation that assigns warehouse unique key,
also called surrogate key, to records from production system database.
Component directly uses one stored procedure which name can be set through SK Procedure property.
This stored procedure is supposed to have output parameter which stores
assigned surrogate key value. Stored procedure name is the only
limitation of this solution: name, number of input parameters and
surrogate key algorithm can be freely modified. Its usage is pretty
simple: user only need to map transform input columns to corresponding
stored procedure input parameters. Component installation comes with
predefined stored procedure and table scripts which are support for
correct component functioning. User is still free to change this
infrastructure if it does not meet his needs. Pexim developed this
transformation to solve surrogate key assignment problem in its own
business intelligence solution. Therefore, component is not completely
generic, but can be widely customized, through implementing surrogate
key assignment logic that best meet user’s business intelligence
solution logic. Also, this is not final release and is subject to
change.
Important Note:
