Each dataclass in the datastore is available as a property of the ds object. The returned object contains a description of the dataclass.
Dataclass objects benefit from specific methods listed in the ORDA - DataClass theme.
C_OBJECT($emp;$sel)
$emp:=ds.Employee //$emp contains the Employee dataclass
$sel:=$emp.all() //gets an entity selection of all employees
//you could also write directly:
$sel:=ds.Employee.all()
