• SQL Server Processing Mining Models & Structures via SSIS

  Still new to DM and SSIS...anyand all help is greatly appreciated! In SSIS they say that you can use the Analysis Services Processing Task to process a mining model/mining structure, however, I do not see where you can give it a relational table to work off of.

That brings me to a more general question, what is the best method for training your models using SSIS I am building a new model everytime the package runs using some variables and the DDL task, running a query on it, and destroying it at the end of the package but I am ha ...Show All
