NULL: There is nothing inside, no string, no number, no data ... Empty: Could only be for strings - nothing to see, but its a string with zero length. Base will save for default all fields without content as NULL, not as fields, which are empty. The difference: You could concatenate empty fields with content of other fields without problems, because it recognizes an empty string. With NULL it won't work. The Help in LibreOffice and the GUI is missleading here, because Base won't save fields as empty fields but as NULL.
