Consider that if there was enough detail in the problem statement that could be "extracted", there would be no need for database design. An "extract utility" would be run that automagically generates the DDL.
Many (most?) problem statements are somewhat nebulous. Someone who knows the business need and how to design database structures (db designer/dba) often meets with the "users" to iron out specifics and then the informaton leads to the first iteration of the database model.
Where to start is probably making Sure you have a good understanding of the "target" - before implementing anything.
