You want to define two database tables with different structures. Both tables should contain
the fields CHANGE_DATE and CHANGE_TIME.
How do you implement this in order to minimize the maintenance effort?
A. Define a structure with these two fields and include this structure in both database tables.
B. Define an append structure with these two fields and assign this append structure to both database tables.
C. Define the two fields in each database table separately.
D. Define the two fields in one database table and copy them to the other database table.
