摘要： A method and system for providing convergence of data copies in asynchronous data replication in a database system, includes: labeling rows, a copy of identification and propagation controls. In applying communicated changes, conflicting changes are identified and resolved. In this manner, convergence of data copies in asynchronous data replication is provided, and processing and storage costs are significantly reduced.

摘要： An XML query compilation processor (20) includes an execution compiler (42) that transforms an XML query into an executable XML query plan (22). A query rewrite processor (34) performs query transformations on the XML query. Said query transformations include transforming an expression input (60) received by an expression (62) conditional upon a set of items defined by an output (64) of the expression (62) being independent of grouping of items in the expression input (60).

摘要： Systems and associated methods for highly parallel processing of parameterized simulations are described. Embodiments permit processing of stochastic data-intensive simulations in a highly parallel fashion in order to distribute the intensive workload. Embodiments utilize methods of seeding records in a database with a source of pseudo-random numbers, such as a compressed seed for a pseudo-random number generator, such that seeded records may be processed independently in a highly parallel fashion. Thus, embodiments provide systems and associated methods facilitating quicker data-intensive simulation by enabling highly parallel asynchronous simulations.

摘要： An apparatus and method for optimizing descendant path evaluation in XPath/XQuery includes generating a list of unique paths in a tree structure of an XML document. Each unique path includes one or more nodes of the tree structure. A query is received specifying a descendant node for retrieval from the tree structure. From the list, unique paths are identified that include the descendant node. A navigation aid is then generated to assist in traversing the unique paths that include the descendant node. Using the navigation aid as a guide, descendant nodes in the tree structure may be retrieved by traversing only unique paths that include the descendant node.

摘要： A dynamic foldering system automatically manages the creation and deletion of run-time dynamic folders and selection of documents, items, or object graphs found in the run-time dynamic folders. The system comprises a query/predicate for a design-time folder group based on which dynamic folders are automatically managed, a variable binding mechanism, automatic identifications of dynamic folders containing a particular object, parallel navigation, and customized combination of foldering results. The dynamic folder hierarchy is defined by a hierarchy of design-time folder groups defined by a query/predicate on a document comprising structured or semi-structured data. Modifiable criteria for creating the dynamic folder hierarchy are provided by the user. Variable binding provides powerful query/predicate definitions on hierarchical data or graph-structured data. Given a document, the system automatically identifies which dynamic folders contain the document.

摘要： The invention herein provides method and apparatus, including software for determining a set of materialized views or indices of the contents or a subset of the contents of a database in a data processing system to be created for one or more users of the database. The method and apparatus provide method and means for evaluating a workload presented by a user to the database; evaluating the data processing system characteristics; evaluating the database characteristics; and, using the above evaluations for recommending a set of suitable materialized views or indices to the user. Another aspect of the invention, which may be used for a workload presented by a user of a database in a data processing system, provides method and apparatus, including software for determining a set of materialized views or indices of the contents or a subset of the contents of the database, by: generating a plurality of materialized view candidates from evaluation of the workload, data processing system characteristics and database characteristics; estimating statistics for the materialized view candidates such as the number of rows, row size, and column statistics; generating a plurality of potential index candidates by evaluating the workload, data processing system characteristics, database characteristics and the materialized view candidates; and, from the materialized view candidates and index candidates selecting a set of suitable materialized views and/or indices for submission to the user.
