Sorry but what exactly do you mean? Just about all standard objects allow DML, I can't think of any that don't. If you can't do it in the API, you can't do it in Apex either.
so CurrencyType just can be updated by update() which is a "Core call". Don't understand exactly what it means but seems that only external applications can invoke it. Doesn't make much sense...
