Modern databases do not have a preset number of fields. Rather, the data architect determines the needed tables and number of fields per table and declares that to the database software. Fields can--with some restrictions--also be added and removed later as needed. That said, each database application does have a maximum limit on the number of fields per table and the number of tables per database, which information has to come from the database manufacturer. But those limits are usually vastly greater than anyone might want. It is part of a computer and it has many fields.
