摘要:
A method, system and article of manufacture for architecting a relationship between different representations of data. One embodiment provides a method of architecting a relationship between a first physical representation of data and a second physical representation of the data. The method comprises mapping the first physical representation to a logical model abstractly describing the second physical representation.

Methods, systems, and articles of manufacture that may be used to create and share annotations for query components, such as query conditions, in an effort to share domain knowledge, are provided. The annotations may be created by users with particular domain knowledge and may contain information useful to other users when building queries including the annotated query components. As an example, an annotation may indicate a particular format or syntax an associated query component should take. For some embodiments, a replacement to the associated query component may also be suggested.

The present invention is generally directed to a system, method and article of manufacture for accessing data represented abstractly through an abstraction model. In one embodiment, a data repository abstraction layer provides a logical view of an underlying data repository that is independent of the particular manner of data representation. For each successive query, the data repository abstraction layer is replaced or redefined to provide a restricted logical view of the underlying data repository.
摘要:
Methods, systems and articles of manufacture are provided for query evaluation. The query is evaluated upon inputting each incremental query element (or combination of element). Generally, for each incremental query element added, a query performance analysis is performed with respect to one or more runtime metrics such as total execution time and runtime resource consumption. The results of the analysis are provided as feedback to the user constructing the query.

Methods and apparatus to optimize workflow execution by making intelligent decisions regarding service requests to perform workflow processes on one or more servers are provided. For some embodiments, a workflow controller may analyze a workflow definition specifying a set of tasks to be performed in order to determine if multiple tasks may be performed locally, on a common server. If so, the controller may generate a remote service to perform the multiple tasks on the common server, without requiring intermediate transfer of data between a local server on which the controller is running and the common remote server.
摘要:
A system, method and article of manufacture for accessing data are disclosed. In general, data access is facilitated by a query configured with a correlation criterion or criteria. The presence of the correlation criteria facilitates the introduction of additional correlation logic to be applied to conditions of the query. In general, correlation criteria are contemplated which support correlation of entities based on time, physical location and age, for example.

A method, apparatus and article of manufacture provide a user interface allowing user selection and arrangement of result fields selected, in one embodiment, from a logical model. In one embodiment, the user interface is a graphical user interface and comprises input cells for user-selected logical result fields. The cells are arranged to define a geometric relationship between logical result fields which dictates the combinatorial statement type by which the logical result fields in the cells are related in a query.
摘要:
A method, system and article of manufacture for processing queries that are executed against a database and, more particularly, for restricting queryable data in a database to a subset of all available data in the database when a query is executed against the database is provided. One embodiment provides a logical representation of all of the available data in underlying physical entities by defining a plurality of logical fields abstractly describing data stored by the associated physical entities, receiving an abstract query comprising at least one logical field of the plurality of logical fields, retrieving at least one condition defining at least one property common to a plurality of physical entities of the queryable data, associating the at least one condition with the abstract query and, in accordance with the at least one condition, restricting the queryable data to the subset of all the available data when executing the abstract query.
摘要:
A system, method and article of manufacture for data processing and, more particularly, for managing execution of complex data access operations in a data processing system. One embodiment provides a method of managing execution of query operations in a data processing system. The method comprises issuing, by a requesting entity, a request to perform a composite query operation defining an initial query operation and a subsequent query operation to be executed against a data repository of the data processing system, executing the initial query operation, determining an operation status of the initial query operation, and managing execution of the subsequent query operation on the basis of the determined operation status.
