This article explains the basic differences among SSIS 2005, SSIS 2008 and SSIS 2012.
Basically, there are no differences between SSIS 2005 and SSIS 2008 at the architectural point of view, but there are additional features added in SSIS 2008.

Summary

This article attemted to explain the basic SSIS differences in various versions of SQL .


What is the Control Flow?

  • When you start working with SSIS, you first create a package which is nothing but a collection of tasks or package components.  The control flow allows you to order the workflow, so you can ensure tasks/components get executed in the appropriate order.

What is the Data Flow Engine?

  • The Data Flow Engine, also called the SSIS pipeline engine, is responsible for managing the flow of data from the source to the destination and performing transformations (lookups, data cleansing etc.).  Data flow uses memory oriented architecture, called buffers, during the data flow and transformations which allows it to execute extremely fast. This means the SSIS pipeline engine pulls data from the source, stores it in buffers (in-memory), does the requested transformations in the buffers and writes to the destination. The benefit is that it provides the fastest transformation as it happens in memory and we don't need to stage the data for transformations in most cases.
