Abstract
An embodiment of the present invention enables manipulation of data on a remote server and ensures uniqueness of data identifiers in a multi-tier environment, where a database client communicates through one or more intermediate servers to reach the target server containing the remote database. In particular, a client system transmits a query to the target server via a gateway system and receives a handle or data reference and a query identification for subsequent manipulation of data residing on that target server. A new query identification is generated by the gateway system and mapped with the query identification of the intended target server. When the client system transmits a query with the gateway query identification, the gateway system performs a lookup operation to identify the corresponding target server and subsequently forwards the query and target server query identification to the identified target server for processing.
