摘要:
The present invention generally provides methods, articles of manufacture and systems for exposing, on a client device, fields of a data model representing an underlying database for use in building queries against the database. For some embodiments, the client device may be a device having limited resources, such as a handheld computing device. Therefore, rather than load and expose the entire data model on the client at once, a limited portion of the data model may be exposed on a client in a “just in time” (JIT) basis. The limited portion may be determined, for example, based on input received from a user and system parameters, such as the system memory and network bandwidth available to the client device.

Embodiments of the invention provide techniques for composing and executing queries using filtered fields. In one embodiment, a query may be composed with compatible fields, meaning filtered fields that store related data of a particular data type. Such compatible fields may be combined into a single query condition, thus simplifying the composition and execution of the query. In one embodiment, fields may be identified as compatible based on metadata included in a database abstraction model.

Embodiments of the invention are generally related to data processing, and more specifically to retrieving results for a query from one or more devices coupled to a network. A first device may receive an abstract query including logical fields defined by a first data abstraction model and retrieve query results stored in the first device. The query may be sent to one or more other devices via the network. The one or more other devices may be configured to convert the abstract query to local abstract queries including logical fields defined in local data abstraction models. The local queries may be issued against local databases to retrieve additional results for the query.

The present invention generally provides systems, methods, and articles of manufacture for maintaining a data warehouse having a plurality of fields updated with data from one or more data sources. Rather than automatically update every field of data available in the warehouse, a limited subset of fields identified through their involvement in queries issued against the warehouse are updated. By limiting the fields that are updated, the network bandwidth required to transmit the updates to the data warehouse may be reduced. Further, by removing fields from the data warehouse that are not in use, the size of the data warehouse may be reduced.
摘要:
A method, system and article of manufacture for managing execution of an abstract query against an underlying database. One embodiment comprises receiving an abstract query against one or more databases having physical data and receiving a user-selection specifying how to apply an abstract filter for filtering data. The abstract query is defined using logical fields of an abstraction model that models physical data of the database(s). If the abstract filter should be applied to the abstract query, the abstract query is submitted to a runtime unit configured to (i) modify the abstract query on the basis of the abstract filter, and (ii) transform the modified abstract query into a physical query suitable for execution against the one or more databases to determine a result set. As a result of executing the physical query, the result set containing data from the one or more databases is received.

In an embodiment, respective strengths are determined for respective relationships in respective statements. Weights are decreased for the respective statements in proportion to respective amounts of time since the respective statements were added to documents. The weights are increased for a subset of the statements that were modified in a subset of the documents. Weighted prevalence data is calculated for respective time periods for the respective statements to be a sum of the weights for the respective statements in the time periods for those statements that have the respective strengths.

Method and apparatus for analyzing a document against a managed research domain are provided. In one embodiment, a managed research domain provides an infrastructure where logical statements in research documents stored in the research domain repository are quantified and semantically analyzed. A user may submit a draft research document for analysis against the managed research domain to compare the draft against the current research knowledge in particular topics. The draft research document is annotated to reflect how the logical statements in the draft compare to the statements made on similar topics in the managed research domain.

A system, method and article of manufacture for managing query results and, more particularly, for sorting data records contained in a query result obtained in response to execution of a query against a database. In one embodiment, the data records in the query result are sorted on the basis of related information which is retrieved from a corresponding data source. In another embodiment, the sorting is performed on the basis of a value variance which is determined for each of the data records in the query result. In still another embodiment, the sorting is performed on the basis of a requested value range coverage. In yet another embodiment, the sorting is performed on the basis of suitability scores which are determined with respect to analysis routines which are configured for processing the query result.
