configuration workbook with all the characteristics of standard fields and repositories (formats..)

Hello Everyone,

I'd like to have a configuration workbook with all the characteristics of standard fields and repositories:

I need to have these information

o the notion of format (char, date...)

and if date = which date format (FR, US…)?

o maximum number of characters

o whether an empty value is accepted by Oracle

o whether the field is mandatory for Oracle to function 

Do you know if we have this type of documentation provided by Oracle?

If so, could you share it with me?

Regards,
