Abstract: A report web service system comprises a web service interface, a report service manager, and a Web Services Description Language (WSDL) generator. The web service interface receives from a Client Application a request for a web service definition for a report as a web service, and transports to the client application the requested web service definition. The report service manager converts definitions of one or more objects in a report definition in a report store that corresponds to the requested report into web service definitions, and generates an object model based on the web service definitions to reflect a structure of the objects of the report. The WSDL generator generates a WSDL definition for the web service based on the object model. When a report as defined in the WSDL definition is rendered, a selector selects relevant objects from a generalized model of the rendered results based on information in the WSDL definition, and a representation formatter formats representation of the relevant objects.

Abstract: A query processing visualization system comprises a visualization module. The visualization module visualizes logging information of query processing events occurring during processing of a client query requesting data from one or more data sources by analyzing the logging information to identify dependency of the query processing events, formatting visual presentation components representing the logging information in a hierarchy to reflect the dependency of the query processing events, and presenting the visual presentation components in the context of the hierarchy of the visual components as formatted.
