hi falko,
  some questions regarding querying 
suppose u have  a database containing 2 classes/tables

Employee , Department.

and we have queries on thesse.

there r 2 ways to handle queries
first the usual relational way
  get all objects of class Employee and of Department
  and then go abt the dirty work

  or
  see if there is a pointer in Employee object to 
  a department object and use that data.(ambiguous since no relation)

  since ozone does not adhere to ODL(definition)
  how does one define relations between objects
  this is important in querying .
  
  right now we are implementing 'select from'
  query of OQL.Parsing is over.Code generation
  is becoming tricky with all the problems i mentioned 
  above

  what do u suggest

bye
das
