Two companies have merged and full database integration is planned for next year. The data architect needs an interim solution to view all employee data from both companies.
The tables come from different systems

Both companies have similar Employees tables

Both tables have identifiers for Employee and some other attributes (e.g., geographical information)

The tables also have some fields that do NOT match (e.g., Social Security Number and Bank Account)

Which problem occurs when the two tables are loaded into Qlik Sense?
