Phase 2 starts from the list of copies or new or modified DB2 tables present in the Work with Changed Data Stores area that are correctly expanded by phase 1 (that is only the record with File Confidence = Recognized) and compares their current structure with what is already defined in the Data Express Knowledge Base to verify if there are matches between their data elements.
At the end of this phase, a list of changed data stores and data elements is produced, which you can verify and approve. Thanks to a confidence parameter, you can identify where the tool could recognize the current features automatically, where a manual confirmation of what has been found is required, or where the match between the original and the modified features must be set manually.
Before moving on to the next phase, you must examine the list in order to confirm what the product has found and, possibly, integrate it with additional information. (See the chapter Work with Changed Data Stores of the Life Cycle Guide.)
