摘要： Techniques to dynamically select data sources for users and to direct queries for the users to the proper data sources. Initially, user information (e.g., user name) for each user is received and used to determine a data source designated for the user. The designated data source may be determined via a look-up table or by running a query with the user information to obtain the identity (e.g., the logical name) of the data source. A data source variable for each user can then be set to the identity of the designated data source. Thereafter, queries for each user are directed to the user's designated data source by determining database connection information for the designated data source based on the data source variable and using this information to direct the queries.

摘要： Techniques to provide dynamic multi-lingual support for software applications such as analytics, which typically rely on two different types of data, underlying data and metadata, to generate reports. The metadata defines the underlying data and a presentation layer displays the reports, which may be generated using presentation and metadata layer objects. Each such object may be defined by a language independent representation, which may in turn be associated with multiple display or language dependent representations (i.e., translations or translated strings) for multiple supported languages. One of the languages may be selected for use in a given session, and the display representations for the selected language are then bound to the language independent representations. The binding may be dynamically performed and is session-specific.

摘要翻译： 为诸如分析的软件应用提供动态多语言支持的技术，分析通常依赖于两种不同类型的数据，底层数据和元数据来生成报告。 元数据定义底层数据，表示层显示可以使用表示和元数据层对象生成的报告。 每个这样的对象可以由独立于语言的表示来定义，其可以依次与多个支持的语言的多个显示或语言依赖表示（即，翻译或翻译的字符串）相关联。 可以选择其中一种语言在给定的会话中使用，并且所选择的语言的显示表示然后被绑定到与语言无关的表示。 可以动态地执行绑定并且是会话特定的。

摘要： A system and method that provide resilient watermarking of digital data, including numeric and categorical relational data. The method and system are premised upon a framework considering the higher level semantics to be preserved in the original data. The system and method also provides a technique for enabling user-level run-time control over the properties that are to be preserved, as well as the degree of change introduced. The system and method are resilient to various important classes of attacks, including subset selection, addition, alteration, or resorting, horizontal or vertical data partitioning, and attribute remapping. For numeric relational data, approximately 40-45% of the embedded watermark may survive approximately 45-50% of original data loss, while for categorical relational data, the watermark may survive approximately 80% of original data loss with only approximately 25% degradation of the watermark.

摘要： A system and methods for providing guarantees about faithful execution of databases that run under the control of an untrusted entity—such as a cloud computing service provider—that is different than the owner of the data and applications being outsourced; or runs on a server that may be compromised by unauthorized users. Specifically, the system and methods establishes that an untrusted database is being faithfully hosted and provides indemnity for the service provider from false claims, enabling the server to prove its innocence against untrue claims of faulty operation. The invention also provides assured provenance for all changes made to the database.
