Techniques are described herein for generating and displaying a confusion matrix wherein a data item belonging to one or more actual classes is predicted into a class. The classes in which the data item may be predicted (the 'predicted classes') are ranked according to a score that in one embodiment indicates the confidence of the prediction. If the data item is predicted into a class that is one of the top K ranked predicted classes, then the prediction is considered accurate and an entry is created in a cell of a confusion matrix indicating the accurate prediction. If the data item is not predicted into a class that is not one of the top K ranked predicted classes, then the prediction is considered inaccurate and an entry is created in a cell of a confusion matrix indicating the inaccurate prediction.

Confusion matrix for classification systems

Embodiments of the invention concern finding correlations between related traded items, such as securities, commodities, currencies, or contracts. The pricing information of multiple traded items from one or more markets is analyzed and a user is provided with a listing of pairs or larger groups of traded items which are most closely correlated. Another embodiment of the invention is a system and method for finding the most related traded item to a particular predefined item. Another embodiment of the invention is a system and method for finding the traded item whose trading history is closest to a predefined curve.

A computerized self-service platform assists merchants in creating and managing stores on a computer network. In one aspect, a system for managing a store includes a product database and an ecommerce storefront, with the ecommerce storefront referencing information in the product database. A product administration module (e.g., a catalog manager) allows the merchant to manage the product database on a self-serve basis. Separating the storefront from the product database can yield numerous advantages.

A technique is provided for generating one or more XML documents from a relational database using the XPath data model. Data stored on a data storage device that is connected to a computer is transformed. Initially, a document object model tee is generated using a document access definition, which defines the mapping between an XML tree structure and relational tables. The document object model tree is traversed to obtain information to retrieve relational data. The relational data is mapped to one or more XML documents.

A method, apparatus, and article of manufacture for a computer implemented modification system for supporting localized data changes in a computer. A change is executed to data in a computer having a local database. The change is performed by the computer to modify data in the local database stored within a data storage device at the computer. The change is indicated as being global. When the local database on the computer is synchronized with a main database on another computer, only global changes are transmitted from the local database to the main database.

Modification system for supporting localized data changes in a mobile device

Provided is a method, system, and program for accessing rows of data from a base table satisfying a search criteria. An initial request to access rows in the base table is received, including the search criteria specifying predicates for one or more columns in the base table. A data structure is generated to include information on qualifying base table rows that satisfy the search criteria. Notification is provided that the qualifying base table rows are accessible before information on all the qualifying base table rows is included in the data structure. A request is then received for one qualifying base table row. A determination is made as to whether the data structure includes information on the requested qualifying base table row. If so, the information in the data structure is used to provide access to the requested qualifying base table row.

Method, system, and program for accessing rows in one or more tables satisfying a search criteria

A technique is provided for creating metadata for fast search of XML documents stored as column data. Data is stored in a data store connected to a computer. A main table is created in a relational database management system, wherein the main table has a column for storing an extensible markup language (XML) document in a native XML format One or more side tables are created in the relational database management system, wherein each side table has one or more columns that store one or more attributes extracted from die XML document for fast searching of the XML document. Thereafter, the side tables are used to locate data in the main table.

XML document stored as column data

The present invention discloses a method, apparatus, and article of manufacture for generating a database application. In accordance with the present invention, a features list is built for the database application. The features list contains user-selected functions. The database application is dynamically configured based on the built features list.

Generating small footprint applications for mobile devices

A technique is provided to store fragmented XML data into a relational database by decomposing XML documents with application specific mappings. Data stored on a data store that is connected to a computer is transformed. Initially, an XML document containing XML data is received. A document access definition that identifies one or more relational tables and columns is received. The XML data is mapped from the application DTD to the relational tables and columns using the document access definition by generating a first document object model tree using the XML document, generating a second document object model tree using the document access definition, and mapping the data from the first document object model tree into columns in one or more relational rabies using the second document object model tree.

A technique is provided for generating one or more XML documents from a single SQL query. Data stored on a data storage device that is connected to a computer is transformed. A query is received that selects data stored in a relational database management system on the data storage device, wherein a data access definition defines: (1) a collection of one or more tables in the relational database management system for storing attributes from an XML document, (2) how data stored in the tables maps to the XML document, (3) a query for mapping the data stored in the tables to the XML document, and (4) a table that will contain the XML document after the XML document is generated. Then, one or more XML documents are generated from the selected data using the data access definition.

Database extender for storing, querying, and retrieving structured documents

Method and apparatus for indexing structured documents with rich data types

A method and apparatus using an extender for a computer-implemented relational database system is disclosed for storing, querying, and retrieving structured documents. The extender provides a new abstract data type and includes a plurality of user defined functions for storing, querying, and retrieving structured documents internally, as character-based large objects (CLOB), or externally, in flat files or URLs, for example. The extender has &ldquo;conditional select&rdquo; functionality, &ldquo;conditional select&rdquo; functionality is based on user defined functions residing within the extender being applied to a projection in a structured query in the database system. The extender also has a set of user defined functions for creating one or more indexes for structured documents stored in the relational database system using already created B&plus; tree index structures implemented in the database system to support the indexes. The method includes a tag counting system for indexing structured documents and for implementing the structure indexes within the relational database.

A method, apparatus, and article of manufacture for data visualization of queries over joins. One or more commands are executed in a computer to perform a database operation on a relational database stored on a data store connected to the computer. Initially, a selection of a join indicator associated with a row of a table in the relational database is received. It is determined whether to perform a table level join operation or a row level join operation. The determined join operation is performed.
