I'm creating a dababase where teachers submit test questions. Often, they submit just one question and thus are assigned a submission number. They may, however, submit one main question with a series of subquestions, in which case they are assigned a common submission number plus a sequential series number. For example:

1

2

3a

3b

3c

4

Would this call for:

a. A single table

b. A single table with a self-join (key = submission number)

c. Two tables

Thanks!

Well, assuming you want to report on all this data, all your test questions should be in one table. Hence, option .
