Data Sampling and Profiling Process Considerations

When you specify the profiling settings, TDC recursively profiles all tables in the import scope (MQL SUBSET SCOPE and object from which you are starting if performing manually) and collects sample rows. Data profiling and metadata import processes share the datastore connectivity and scope details. You do not need to configure the data profiling connectivity explicitly.

The data profiling process collects information that contains data values. It makes an effort to protect the information and show it to authorized users only and encrypts the information in its database. See Showing and Hiding .
