Description: A conceptual row in the artSummaryTable.

Each row corresponds to an application response time report for an individual {data source, application-protocol, server} triple. Values in the each row correspond to the summary of response time information of all clients of the associated server, whereas the rows in the artTable contain detailed information for {data source, application- protocol, client, server} quadruples.

Rows are created and deleted by the probe, and all objects are read-only to the NMS.

Rows are indexed (in effect) by data source, application protocol identifier, and server address.

Note that only the server address index component corresponds to an object in the table.
