6594 results about "Data query" patented technology

A query is a request for data or information from a database table or combination of tables. This data may be generated as results returned by Structured Query Language (SQL) or as pictorials, graphs or complex results, e.g., trend analyses from data-mining tools.

Authenticated access to internet based research and data services

Access to a database is provided via the Internet using a World Wide Web server including a search engine, a CGI gateway and user selectable data queries for extracting data, generating reports, and the like. Access by the user is authenticated by querying the user's central machine for authentication. The authentication process operates by sending a page request from the web browser through three checkpoints before the requested page can be served to the web browser. The first checkpoint determines if the requested page is protected. If not, the requested page is served to the web browser. However, if the requested page is protected, the authentication process on the web server checks the host name of the system where the page request is coming from. If the domain of the requesting host is the same domain specified in the web authentication configuration, then the requested page is served to the web browser. However, if the page request is determined to come from outside of the domain of the web server, then the authentication process checks a "cookie" from the web browser to determine if the requesting user has been authenticated as an authorized user earlier in the same session. If the cookie has been "set" during the login procedure, then the requested page is served to the web browser. Otherwise, the user is prompted with a login page. After the user ends the web browser session, the cookie is cleared. Data Query software at the web server permits queries initiated via a web browser to be completed off-line and the results e-mailed to the initiator of the request.

Query language for unstructed data

A system and methods are provided for interactive construction of data queries. One method comprises: generating a query based upon a plurality of user-identified data items, wherein the user-identified data items are data items representing desired results from a query, and wherein information related to the user-identified data items is included in a “given” clause of the query, assigning received input data to a hierarchical set of categories, presenting to a user a plurality of new query results, wherein the plurality of new query results are determined by scanning the received input data to find data elements in the same hierarchical categories as those in the “given” query clause and not in the same hierarchical categories as those of an “unlike” clause of the query, receiving from the user an indication as to whether each query result of the presented plurality of new query results is a desirable query result, adding query results indicated by the user as desirable to the “given” clause of the query, adding query results indicated by the user as undesirable to the “unlike” clause of the query, evaluating a metric indicative of the accuracy of the query, and responsive to a determination that the query achieves a predetermined threshold level of accuracy, storing the query.

Computer-related method, system, and program product for controlling data visualization in external dimension(s)

A computer graphics display method and system for controlling data visualization in at least one external dimension is provided which allows better querying and navigation of data in external dimension space. A data visualization is displayed in a first display window. A summary window provides summary information on data for the data visualization across one or more external dimensions. First and second controllers are displayed for controlling the variation of the data visualization in respective first and second external dimensions. A user queries the data visualization in the first and second external dimensions by selecting a point in the summary window. A user navigates through the data visualization in the first and second external dimensions by defining a path in the summary window. Grid points are also displayed in the summary window to facilitate data queries and navigation based on actual data points. The first and second controllers can be first and second sliders, such as, slide buttons, dials, or any other type of input. An animation control panel, including tape-drive controls, a path control, and a speed control, controls an animation of the data visualization over a selected navigation path through external dimension space.

Multi-source heterogeneous database fusion system and data query method thereof

The invention provides a multi-source heterogeneous database fusion system and a data query method thereof. The system comprises a database layer, a data fusion layer and a uniform application layer. The database layer is composed of heterogeneous databases and agencies of the heterogeneous databases. The data fusion layer is used for fusing information of all heterogeneous data sources, and is responsible for data access of the heterogeneous data sources and coordinating the information of all the data sources, and specifically comprises a metadata data base (DB), a metadata manager, a comprehensive wrapper, a mediator, an application layer access uniform interface and a heterogeneous database uniform interface. The uniform application layer is the user of the heterogeneous database fusion system and can have access to shared data resources of the heterogeneous databases by fusing middle layers. The multi-source heterogeneous database fusion system and the data query method of the multi-source heterogeneous database fusion system solve the problems in heterogeneous database fusion and overcome the defects of an existing database fusion technology. The system can conduct transparent query on all the heterogeneous databases on the condition that local databases are not affected, and the maintenance cost of the system is reduced.
