 From Setup storage to WSDL to Restful  services. (But it is almost 
about online ordering of material)

I don't think so. (ATM, several people have tried by using string mixins)
  But I can imagine at least one (imo) smart solution.
Enable compiler plug-in's so that you can write ..

void ExecSQLQuery()
   DataTable dt = new DataTable();

   SQL92{ /*like asm {} */
     dt = SELECT * FROM Customer WHERE IsPotentialClient = 1;
   }

}
//which translates into D code  (the D lexer/parser unit calls the D2 
SQL92 Translator generator which generated this D source)

   import SQL92
   dt = db.Select("SELECT * FROM Customer WHERE PotentialClient = 1");


This translation feature could be generic.. we can create a translator 
based on
Annotated EBNF In -> Annotated EBNF out

In fact I've created a tool (in Java) to translate SQL scripts. Firebird 
to  MSSQL respective PosgreSQL.
Hope this gives you an idea.. :)
