摘要：
We describe the Query Agent and Query Engine for the Science Archive of the Sloan Digital Sky Survey. In our client-server model, a GUI client communicates with a Query Agent that retrieves the requested data from the repository (a commercial ODBMS). The multithreaded Agent is able to maintain multiple concurrent user sessions as well as multiple concurrent queries within each session. We describe the parallel, distributed design of the Query Agent and present the results of performance benchmarks that we have run using typical queries on our test data. We also report on our experiences with loading large amounts of data into Objectivity.
