RECOMMENDATIONS

(1) DON'T TRY TO CREATE A PERFECT MODEL IN THE FIRST RUN!

  • Start with a first draft and move to (2)

(2) START TESTING AS EARLY AS POSSIBLE (or even earlier)

    • Get (or create) real life data to test the model.
    • Store the data in formally structured Excel-Sheets,
      i.e. one table for each entity with columns containing the values of the attributes
    • Load the Excel-Sheets into the repository -> MetaEXL facility of metasafe
    • Define UseCases and check the data against these UseCases
    • Use the MetaEditor and especially the erSQL queries to extract the data which are required for the Use Cases.
    • If the model does not fit return to the modeler and update the model.

(3) PLAN FOR SEVERAL CYCLES OF REFINEMENT

(4) WHAT EVER THE RESULT IS – CHANGE WILL HAPPEN
