摘要： Methods and systems for analyzing XML documents. The system scans an XML document, identifies different dimensions that span the XML document and detects scoping relationships amongst them. The system uses the dimensional information to create a logical hierarchical scoped dimension analysis model, maps the logical XML tree to this model, and then implements the analytical method over the logical model. The logical model allows both structural features and numeric/non-numeric data to be used for analysis. The analytical method allows users to query irregular structural properties of the XML documents using the XPath navigational API.

摘要： Techniques are disclosed for optimizing queries to hierarchically structured data. For example, a method for processing a query directed to data having a hierarchical structure with a plurality of data nodes comprises the following steps. One or more structural attributes describing the hierarchical structure of the data are identified. The query is partitioned into two or more query partitions using at least one of the one or more identified structural attributes. A parallel execution plan is determined for the query by splitting into components one or more of: the query into at least two of the query partitions; and the hierarchical structure of the data. The split components are executed in parallel on different computer processes according to the parallel execution plan.

摘要： A computer system and method for compiling a program, where the program executes pointer assignments from a source object to a destination object, each source object being addressable through a first pointer and each destination object being addressable through a second pointer. The system and method eliminate write barrier code from association with compiled program code when the first pointer points to a source object whose type is prolific, eliminate write barrier code from association with compiled program code when the second pointer points to a destination object whose type is non-prolific, and associate write barrier code with compiled program code when the source object is non-prolific and the destination object is prolific. Additionally, the system and method can determine not to associate write barrier code with a compiled program code if the second pointer points to a destination object whose type is non-prolific and if the first pointer points to a source object whose type is prolific.

摘要： A method and system for clustering of XML documents is disclosed. The method operates under specified memory-use constraints. The system implements the method and scans an XML document, assigns edge-weights according to the application workload, and maps clusters of XML nodes to disk pages, all in a single parser-controlled pass over the XML data. Application workload information is used to generate XML clustering solutions that lead to substantial reduction in page faults for the workload under consideration. Several approaches for representing workload information are disclosed. For example, the workload may list the XPath operators invoked during the application along with their invocation frequencies. The application workload can be further refined by incorporating additional features such as query importance or query compilation costs. XML access patterns could be also modeled using stochastic approaches.

摘要： Systems and methods for parallel stream item counting are disclosed. A data stream is partitioned into portions and the portions are assigned to a plurality of processing cores. A sequential kernel is executed at each processing core to compute a local count for items in an assigned portion of the data stream for that processing core. The counts are aggregated for all the processing cores to determine a final count for the items in the data stream. A frequency-aware counting method (FCM) for data streams includes dynamically capturing relative frequency phases of items from a data stream and placing the items in a sketch structure using a plurality of hash functions where a number of hash functions is based on the frequency phase of the item. A zero-frequency table is provided to reduce errors due to absent items.
