Abstract: One embodiment is a method to manage queries in a database. The method identifies a query that executes on the database for an elapsed time that is greater than a threshold and then implements a remedial action when the query executes on the database for an execution time that is greater than an estimated execution time.

Abstract: One embodiment is a method that generates query vectors from query plans and performance vectors from data collected while executing multiple queries in a database. A machine learning technique (MLT) computes distances between two query vectors and two performance vectors and then predicts performance of plural queries executing in the database.

Further, the integrated information of the embodiment includes the requirement, the potential solution, and a link between the requirement and the potential solution.

Abstract: A network service system comprises a service registry adapted to interact with registry clients. The service registry includes a service registry interface operatively coupled to a service data registry and a metadata registry for processing unstructured queries from registry clients.

Abstract: One embodiment is a method that generates points from an input space obtained from a query for a database. A kernel function maps the points from the input space to a feature space. Given a point in the feature space, a reverse mapping identifies coordinates in the input space for the point to predict performance of the query before the query executes in the database.

Abstract: Embodiments of the present invention relate to a system for correlating configurations, comprising a model layer having a generic model library, a control layer having generic control logic implemented in terms of the generic model library, and a view layer having reusable views and common tools that operate upon generic interfaces and constructs defined by the generic model library, wherein the generic model library, generic control logic, and reusable views and commons tools are defined to support a general functionality.

Abstract: A method and system for the transformation of extensible markup language (XML) documents. Specifically, one embodiment of the present invention discloses a method comprising modeling a source XML document corresponding to a source schema as a source tree having a plurality of source nodes, and modeling a target XML document corresponding to a target schema as a target tree having a plurality of target nodes. A sequence of transformation operations that transforms the source tree to the target tree is then generated.

Abstract: A computer language for facilitating communication between web services, where web services may use disparate input and output document formats, and system using same. A Conversation Definition Language (CDL) is extended with transformational information to a Transformational Conversation Definition Language (TCDL). The CDL defines document types, transitions and interactions of a conversation between two or more web services. In a preferred embodiment, the transformational information is a subset of the interaction information. Stylesheets are used to define the semantics of the required transformation and the appropriate stylesheets are identified in the TCDL file. A conversation controller component reads the TCDL files that correspond to a given conversation and utilizes the transformation information, when necessary to transform documents between web services without human intervention.

Abstract: Provided are systems, methods and techniques for, among other things, generating a master price quotation. In one representative embodiment, a representative creates a list that includes at least one item to be included within a master price quotation and submits the list to an automated bidding agent. In response, the automated bidding agent communicates requests for quotations to different automated entity agents, each such automated entity agent corresponding to a different entity. The automated bidding agent then receives the quotations from the automated entity agents, selects a best quotation, and communicates the best quotation to the representative for inclusion within the master price quotation.

Abstract: One embodiment is a method that obtains query plans for queries in the workload. The query plans include a tree of operators and estimated cardinalities for nodes in the tree. The method then groups the operators for the queries and characterizes the workload in terms of grouped operators to predict performance of the queries before the queries execute in a database.

Abstract: One embodiment is a method that generates query vectors from query plans and performance vectors from data collected while executing queries in a database. The method then uses a machine learning technique (MLT) to compute distances between two query vectors and two performance vectors and to predict performance of executing a new single query in isolation in the database.

A machine learning technique (MLT) computes distances between two query vectors and two performance vectors and then predicts performance of plural queries executing in the database.

Abstract: A method, system, and apparatus is disclosed for interfacing with a distributed computing service. A semantic interpretation specification can be accessed that describes a behavior used to interface with the distributed computing service. The semantic interpretation specification is entered into a rules engine. A set of procedures is obtained from the rules engine for interacting with the distributed service. An interface with the distributed computing service can be formed using the set of procedures.

Abstract: A method of tracking an identification device includes storing data about the identification device in a register, the data to be stored including data relating to a forwarding location to which requests for information about the identification device should be forwarded. The identification device is attached to an item to be monitored. The method includes accessing the register when the identification device has been read and a request for information has been received. Details of the forwarding location are obtained from the register. The request is forwarded to the forwarding location and the requested information about the identification device is sent from the forwarding location to a requester of the information.

Abstract: A system and method for resource handling provides for receiving a query and providing a response. The query is used to search resources locally available. Metadata is associated with each of the resources. The resources and the metadata are both analyzed with respect to the query such that a response indicative of a match between at least two of the resources and the query is a ranked search result included in the response. The invention is exemplified in an adaptation to peer-to-peer network applications.

Abstract: A method and system of valuing transformation between XML documents. Specifically, one embodiment of the present invention discloses a method for calculating a transformation cost for a transformation operation that transforms a source node in a source XML document to a target node in a target XML document. A data loss and potential data loss is measured for the transformation operation. Also, the operands in the transformation operation are scaled to measure their impact on the data loss and potential data loss. A transformation cost is calculated by considering the data loss, potential data loss, and scaling.
