    摘要: Techniques are provided for automatically rewriting a relational-to-hierarchical mapping into one or more modified mappings. In this way, clients that prefer or require different portions of the mapping-defined data are supported. For example, in one aspect of the invention, a technique for modifying a relational-to-hierarchical mapping in accordance with at least one user query includes the following steps/operations. At least one query associated with a query language that supports a hierarchical data structure is obtained. Further, at least one relational-to-hierarchical mapping for use in translating data associated with a relational data structure into data associated with the hierarchical data structure is obtained. Then, the at least one relational-to-hierarchical mapping is modified based on the at least one query such that data specifically relevant to the at least one query may be generated in accordance with the modified relational-to-hierarchical mapping.

    摘要: A system and method of converting a recursive XML document into a relational schema comprises providing a recursive XML document; parsing an external mapping script specifying a mapping from the recursive XML document to a relational table format; building a recursive shredding tree based on the external mapping script and the relational table format; and shredding the mapped recursive XML document into a relational table. The system and method further comprise detecting whether any of a XML schema and a DTD document is recursive, wherein the detecting comprises building a directed graph comprising element names; corresponding elements names as nodes in the directed graph; forming arcs from every element parent node to every element child node of the element parent node; and checking for cycles in the directed graph. The system and method further comprise identifying all recursive cursor nodes and a recursive degree corresponding to the recursive shredding tree.

    摘要: A learning-based method for estimating costs or statistics of an operator in a continuous query includes a cost estimation model learning procedure and a model applying procedure. The model learning procedure builds a cost estimation model from training data, and the applying procedure uses the model to estimate the cost associated with a given query. The learning procedure uses a feature extractor and a cost estimator. The feature extractor collects relevant training data and obtains feature values. The extracted feature values are associated with costs and used to create the cost estimator. When applying the cost estimator to a continuous stream of data, the feature extractor extracts feature values from the data stream and uses the extracted feature values as inputs into the cost estimator to obtain the desired cost values.

    摘要: The present invention features therapeutic bacteriophage deficient in the lysin protein (“Lys minus” phage). Lys minus bacteriophage are incapable of facilitating efficient lysis of the bacterial host since the enzymatic activity of the lysin of the phage is needed for breaking down the peptidoglycan layer of the bacterial cell wall. Lys minus bacteriophage retain activity in invasion of its appropriate bacterial host, destruction of the bacterial genome, and replication, which are sufficient to inhibit bacterial growth and replication. Therefore, the therapeutic Lys minus phage stops the spread of infection by the bacterial pathogen without lysis of the bacterium. This approach is attractive as it also prevents the release of the phage progeny, thus reducing or eliminating the potential for generation of immune responses against the phage. The incapacitated bacterial pathogen is then removed by the normal defense systems such as phagocytes and macrophages.

    摘要: A tagging tree that defines a hierarchical output data structure and relational database query operations that retrieve the data to be included in each hierarchical section is accepted and processed. A query optimizer analyzes the tagging tree to determine database query operations that can be combined into a single query command. An outer-union query command is generated to allow efficient combination of multiple query commands, some of which are predicates to others. The tagging tree is modified to replace the database queries that were combined into the outer-union query to extract data from the results set produced by the outer-union query as opposed to submitting queries to the database manager. The optimized queries can be reused an arbitrary number of times to leverage the optimizing resources that were used in their creation.
