摘要:
Embodiments of the invention allow structured data to be transferred between a source application and a target application that process structured data in different formats. For example, structured data may have a set of associated rules which transform the structured data based on a set of variables. The source application may register variable definitions for each of the variables in a registry. The target application may read the registry and register values for each of the rule variables. Once values are registered for the variables, the source application may transfer the structured data to a transformation engine that applies the rules, using the registered values for the variables, to transform the structured data into a format compatible with the target application. In doing so, the transformation engine can generate a document in any format compatible with the target application and subsequently transfer the generated document to the target application.

Embodiments of the invention allow structured data to be transferred between a source application and target applications that process structured data in different formats. For example, structured data may have associated rules which transform the structured data based on some variables. The source application may register variable definitions for each variable in a registry. Each target application may read the registry and register values for the variables. Once values are registered, the source application transfers the structured data to a transformation engine that applies the rules, using the registered values for the variables, to transform the structured data into a format compatible with the target applications. The transformation engine may also determine distinct sets of variable values and transform structured data based on each distinct set. In doing so, the number of transformed data generated is limited to the number of distinct sets, thereby avoiding generating duplicate transformed data.

Methods, articles of manufacture and systems are provided for simplifying a query building process by limiting the number of fields presented to a user for building queries. The number of fields presented to the user may be limited by hiding one or more logical fields from the user based on usage characteristics. For example, a logical field that is rarely used or has not been used within a predetermined period of time may be hidden from the user. For some embodiments, a fallout manager may monitor the use of logical fields in building queries, update usage characteristics, and mark logical fields as hidden based on the usage characteristics. A graphical user interface may not present to a user logical fields that have been marked as hidden.

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:
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.

Methods, systems and articles of manufacture for performing multiple request processing. Redundant instances of executing entities service requests in a time-delayed fashion, relative to one another. In this way, a user can be returned to an earlier state by switching to the execution flow of one of the other executing entities.
摘要:
The present invention generally is directed to systems, methods, and articles of manufacture for securing sensitive information involved in database transactions. Embodiments of the present invention selectively encrypt only portions of transactions involving sensitive data, thereby reducing or eliminating the processing overhead resulting from wastefully encrypting non-sensitive data. The sensitive data may be identified by a document. The document may be accessed by a requesting entity to determine which portions of a query should be encrypted prior to sending the query to a database server over a network. The document may also be accessed by a database server to determine which portions of query results should be encrypted prior to sending the query results to the requesting entity over the network.
摘要:
A method, system and article of manufacture for executing database queries where the data being queried resides in both relational databases and other external data sources, and, more particularly, for creating a dynamic, just in time, database table using data retrieved from an external source. One embodiment provides a method of processing a database query. The method includes receiving, from a requesting entity, an abstract query of data contained in a database and an external data source, the abstract query being defined using logical fields of a data abstraction model abstractly describing the data in the database and the external data source. The method further includes generating, from the abstract query, an executable query capable of being executed by a query engine, wherein the executable query includes a reference to a temporary data structure, generating the temporary data structure using data retrieved from the external data source, and executing the executable query against the database and the temporary data structure to obtain a result set.
