Method and apparatus for fetching array based objects by direct delivery and batching

Abstract

A method, apparatus, article of manufacture, and a memory structure for providing access to an array-based data object to a client is disclosed. The method comprises the steps of receiving a database query from a client; generating a first execution plan from the database query; transmitting at least a portion of the first execution plan to a data server; compiling a query result from the execution of the first execution plan; and transmitting the query result to the client on a first communication path wherein the query result comprises an identification for a master data object responsive to the database query and the master data object comprises an identification for a plurality of array-based objects associated with the master data object. Further, the method comprises the establishment of a second communication path between the data server and the client and the transmission of the master data object to the client via this second communication path. This is followed by a third request by the client for the required array-based objects. This results in the generation of a third execution plan which is executed by the appropriate data server. The resultant array-based objects are then tagged with the corresponding object identification and sent in batched fashion directly to the client via the second communication path.
