How correct is it to create universal tables?

Question

PHP

Such a situation, I have 2 types of objects, there is only one difference, one has the "Header" field, the other "Id", to the object (1st type) of which the object of the 2nd is attached. type.
How do GURUs act in such a situation when creating a table?
Make the "Title" field universal or make 2 fields or 2 different tables?
Question about style

Answer 1

If there are two different objects, but they just have similar properties, you should not mold them into one table.
For the simple reason that if a new requirement appears (and it will, sooner or later) that will require significant differences in both objects - you get hit :)
Tip: different objects = different tables.
