Abstract
A method and apparatus are provided for supplying data to users through “query objects”, where the data corresponds to attributes of domain objects and is stored in a relational database. The query objects create a bridge between the information the user wants to see (as expressed in the user interface presented to the user), the object model in which domain logic is implemented, and the relational model in which the data is stored. Thus, data used to populate the user interface is queried directly from the data model and returned in the shape required by the user interface. As the query results are read into memory, objects that model the data using object-oriented techniques are instantiated. Subsequent manipulation of the data is redirected to those objects, thereby preserving data encapsulation and allowing reuse of existing logic.
