摘要： A query runtime architecture and an exemplary application programming interface suitable for the architecture are presented. The architecture inputs one or more XML queries and views and enables the queries to be translated wherein the queries and views may be run over multiple data sources of different data models. The architecture incorporates front-end compilers which convert input queries and views into an intermediate language representation which represents the meaning of the respective query or view. The architecture may then allow the back-end compiling of the intermediate language representation to target languages compatible with the data sources desired to be queried. The architecture also allows the execution of those target compilations to extract the data requested of the queries. The invention also discloses an example application programming interface for the query runtime system.
摘要翻译：提出了一种适用于架构的查询运行时架构和示例性应用程序编程接口。该架构输入一个或多个XML查询和视图，并且使得可以翻译查询，其中查询和视图可以在不同数据模型的多个数据源上运行。该架构包含将输入查询和视图转换为代表相应查询或视图的含义的中间语言表示的前端编译器。然后，架构可以允许将中间语言表示的后端编译目标为与期望被查询的数据源兼容的语言。该架构还允许执行这些目标编译以提取查询请求的数据。本发明还公开了一种用于查询运行时系统的应用编程接口示例。

摘要： A distributed query engine pipeline architecture comprises cascaded analysis engines that accept an input query and each identifies a portion of the input query that it can pass on to an execution engine. Each stage rewrites the input query to remove the portion identified and replaces it with a placeholder. The rewritten query is forwarded to the next analysis engine in the cascade. Each engine compiles the portion it identified so that an execution engine may process that portion. Execution preferably proceeds from the portion of the query compiled by the last analysis engine. The execution engine corresponding to the last analysis engine executes the query and makes a call to the next higher execution engine in the cascade for data from the preceding portion. The process continues until the results from the input query are fully assembled.
摘要翻译：分布式查询引擎流水线架构包括级联分析引擎，其接受输入查询，并且每个引擎识别可以传递给执行引擎的输入查询的一部分。每个阶段都会重写输入查询以删除已识别的部分，并用占位符替换它。重写的查询将转发到级联中的下一个分析引擎。每个引擎都会编译其识别的部分，以便执行引擎可以处理该部分。执行优先从最后一个分析引擎编译的查询部分进行。与最后一个分析引擎相对应的执行引擎执行查询，并对来自前一部分的数据进行级联的下一个较高执行引擎的调用。该过程一直持续到输入查询的结果完全汇编为止。

摘要： A data mapping architecture for mapping between two or more data sources without modifying the metadata or structure of the data sources themselves. Data mapping also supports updates. The architecture also supports at least the case where data sources that are being mapped, are given, their schemas predefined, and cannot be changed. The architecture includes a mapping component that receives respective metadata from at least two arbitrary data models, and maps expressions between the data models.

摘要： The present invention relates to a system and methodology to facilitate data communications and data management between network entities operating in accordance with various data structures and operating environments. A managed class of application programming interfaces (API) are provided that support data communications between remote/local locations employing a first data structure and a second location supporting a second data structure (e.g., API for NET languages to access SQL Server via XML views). The managed class and associated APIs provide data transformations between such structures to facilitate communications and data management among various locations and architectures. In addition, the managed class and APIs facilitate operations between disparate object systems such as between managed and unmanaged object systems via interface support of a wrapper and associated marshalling technologies to bridge communications between such systems.

摘要： Embodiments are directed to predicting the health of a computer node using health report data and to proactively handling failures in database services. In an embodiment, a computer system monitors various health indicators for multiple nodes in a database cluster. The computer system accesses stored health indicators that provide a health history for the database cluster nodes. The computer system then generates a health status based on the monitored health factors and the health history. The generated health status indicates the likelihood that the node will be healthy within a specified future time period. The computer system then leverages the generated health status to handle current or predicted failures. The computer system also presents the generated health status to a user or other entity.

摘要： The subject disclosure pertains to computer programming languages and translation or conversion thereof. Rather than a complicated semantics preserving translation or conversion from a first source language to a second target language, the conversion can be one of syntax. The conversion can be accomplished, for example, via employment of a map that defines the relation between the syntax of the first language and the second language. The semantics of at least a part of the first language can be defined by the second target language. Thus, the first language can be open-ended and/or semantically extensible based on the second language.
摘要翻译：本发明涉及计算机编程语言及其翻译或转换。而不是从第一源语言到第二目标语言的复杂语义保留翻译或转换，转换可以是语法之一。该转换可以例如通过使用定义第一语言和第二语言的语法之间的关系的映射来实现。第一语言的至少一部分的语义可以由第二目标语言定义。因此，基于第二语言，第一语言可以是开放的和/或语义上可扩展的。
