Chapter 23. Case Study: A Programmatic Example
Typically a book like this has to cover so much material that there is not enough space to really dig into some of the typical issues that you run into when you put the book down and start putting together your first solution. You end up coming back to the book to flip through all of the one-off examples, but they just don't seem to provide any insight or applicability to your current project or deadline. The case study is your best chance to get specific, to get into the ring, to take a business issue and run with it. Hopefully you'll be the beneficiary of this.
You will use the SSIS environment to solve a payment processing problem with payment data of varying levels of quality that has to be validated against corporate billing records. This example is a little different from the typical data-warehouse-type ETL case study; it's a little more programmatic. Not to say that there is not any ETL. You'll need to import three heterogeneous data formats, but the interesting part is the use of the SSIS Data Flow Transforms that allow for the development of smart validation and matching programming logic. This will all combine into a solid learning opportunity that showcases the real capabilities of SSIS.
What You Will Take Away
The principal advantages of this case study are multiple opportunities to highlight specific techniques and use-cases that you can take away and add to your SSIS toolkit. Specifically, you'll get examples of:
