Answer

'Column Name' is the name of the column in the DataWindow. You always refer to this name when you want to change the column attributes. You can change the column name in the DataWindow. The 'Database column name' is the name of the column in the database and you can't change this name. Typically, this name is prefixed with the database and table and owner name. You can see both column and database column names by selecting 'Rows/Columns' in the DataWindow when you are in the DataWindow design mode.
