Summary:A computer-implemented method processes a query on instances of an object of an object-oriented environment. The object has a root object and member fields which are sub-objects of the root object. The root object and each sub-object correspond to an entity represented by and stored in form of a table. The method includes analyzing the query to identify those objects which are necessary to execute the query. For each of the primary key values of a table corresponding to a root object, the method includes:(i) generating an instance of the object by populating the member fields of those objects which have been identified as necessary in said analyzing step with data identified by the respective primary key in their corresponding tables; (ii) executing the query on the generated object instance; and (iii) adding the query result to a result accumulator storage.
