A method of transferring data between a first system and a second system while ensuring the integrity. Metadata is associated with each data record and is used to ensure the integrity of the transfer.

Maintenance of data integrity during transfer among computer networks

A method and apparatus are provided for supplying data to users through &ldquo;query objects&rdquo;, 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.

Accessing domain object data stored in a relational database system

A computer system and method for accessing an altered database architecture using existing code. The present invention transforms information which is stored in a new format in a database such that it appears to existing code to be stored in an old format. In so doing, existing code which was originally designed to access the information stored in the old format is able to access the information stored in the new format. Thus, the present invention allows a user to access information contained within an altered database architecture using existing code.
