摘要:
Techniques are disclosed for helping users determine the “best” places to use and acquire inventory objects within a virtual environment, as well as to notify users of useful inventory items when an avatar is at a particular location in the virtual environment. An object index may be used to store data describing attributes of virtual objects, and a user index may be used to store data describing interactions users engage in with virtual objects.

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.

摘要:
A computer-implemented method includes receiving a selection of a particular logical field via a database query interface. The method includes querying a discovery registry associated with a data abstraction model of a database to discover one or more web services. A web service input and a web service output of a particular discovered web service are associated with logical fields of the data abstraction model via the discovery registry. The method further includes initiating execution of a discovered web service that returns a list of values. The list of values obtained by the discovered web service may be augmented with information determined based on field relationship metadata of the data abstraction model.
摘要:
A computer-implemented method includes receiving a selection of a particular logical field via a database query interface. The method includes querying a discovery registry associated with a data abstraction model of a database to discover one or more web services that are resolvable based on the particular logical field. The data abstraction model includes a plurality of logical fields, where each logical field corresponds to a particular data structure of the database. A web service input and a web service output of a particular discovered web service are associated with particular logical fields of the data abstraction model via the discovery registry. The method further includes automatically initiating execution of the discovered web services and displaying one or more values resulting from execution of the discovered web services.
摘要:
A method includes receiving a selection of a logical field of a data abstraction model. The method includes determining model entries (e.g., concepts) associated with the selected logical field and examining the data abstraction model to determine other model entries that are equal to the model entries associated with the selected logical field. For each equal model entry, the method includes determining web services to be used in performing a search, where the web services are determined by querying a discovery registry associated with the data abstraction model to discover one or more web services that are resolvable based on the selected logical field. A first discovered web service is executed with user supplied criteria provided via a user interface to obtain a list of values. A condition is created that limits acceptable values associated with the selected logical field based on the user supplied criteria.
