Once the collation has been performed, causing the results to be brought back together, the remaining piece of the custom program is the presentation logic. As mentioned previously, this is performed in a separate program called the Transformation program. The reasoning behind the separation of the processing and transformation logic is three-fold:

  • Processing logic and presentation logic are completely separate, leading to increased program clarity and reduced maintenance costs
  • Further restriction of the collated results can be achieved
  • Results of different instances can be viewed interactively and repeatedly by different users
