Abstract: A query of at least one mark-up language document has a path expression comprising a conjunction, a first filter and a second filter. The first filter has a first probe. The second filter has a second probe. The first and second filters form a between filter having start and stop values specified by the first and second probes. A plan to process the query is generated based on, at least in part, a range defined by the start and stop values. An index of mark-up language documents is defined by another path expression; the index comprises values of mark-up language documents that satisfy the other path expression; the values are key values of the index. The plan is to perform a single scan of the key values from the start value to the stop value to identify at least one key value that satisfies the between filter.

Abstract: Various embodiments of a system and computer program product to access metadata from a plurality of data servers from a federated database management system are provided. In one embodiment, a request for metadata, from a client application, is received by the federated database management system. Data servers which are accessible from the federated database management system are identified. For each data server, metadata describing data of a data source of that data server is retrieved in accordance with the application request. The retrieved metadata from each of the data servers is aggregated to produce an aggregated result in a uniform format. The aggregated result is provided. In another embodiment, for each data server, a source metadata request for metadata of that data server is generated in accordance with the application request and a source metadata application programming interface. A view is created based on the source metadata request for metadata for each data server.

Abstract: A first log reader publishes first messages to a plurality of queues. The messages comprise changes for transactions extracted from a log by the first log reader.
