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： 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： An architecture that leverages support for markup language operations, e.g., extensible markup language (XML) queries, via a lightweight application program interface (API). The API defines an object model that can simplify construction of XML values in languages that do not natively support XML. The novel aspects of the described innovation can enable query languages to be factored into general operations (e.g., mapping, filtering, sorting, and/or projection of functions) on collections on one hand, and a set of domain specific operations (e.g., navigation, construction and modification) on the elements of these collections on another hand. The subject API can support creation of XML data that is node centric (e.g., context-free). Accordingly, nodes do not have to be constructed within the context of a document. Additionally, aspects can enable expression-oriented interface mechanisms as opposed to the imperative statement-oriented style interfaces used in connection with traditional interface mechanisms (e.g., DOM).
摘要翻译： 通过轻量级应用程序接口（API）利用支持标记语言操作（例如可扩展标记语言（XML）查询）的体系结构。 API定义了一个对象模型，可以简化XML本身不支持XML的语言的构造。 所描述的创新的新颖方面可以使查询语言能够一方面被视为一般操作（例如，功能的映射，过滤，排序和/或投影），以及一组特定于领域的操作（例如，导航 ，建设和修改）另一方面对这些收藏品的要素。 主题API可以支持以节点为中心（例如，无上下文）创建XML数据。 因此，节点不必在文档的上下文中构建。 另外，方面可以实现面向表达式的接口机制，而不是与传统接口机制（例如，DOM）结合使用的面向语句的风格接口。

摘要： The subject invention pertains to a system and method of incorporating collation information into data types. In particular, the subject invention provides for parameterizing data types with collation information such that a comparison between two different collations generates a static-type error rather than a run-time error. Additionally, the invention affords for conveniently working with localized data types to allow generic parameterization over collations as well as ordinary types. In the context of strings, the present invention enables concurrent use of strings in multiple languages and facilitates the correct handling thereof.
摘要翻译： 本发明涉及将归类信息并入数据类型的系统和方法。 特别地，本发明提供了用归类信息参数化数据类型，使得两个不同排序顺序之间的比较产生静态类型错误而不是运行时错误。 此外，本发明提供了方便地使用本地化数据类型以允许通过归一化以及普通类型的一般参数化。 在字符串的上下文中，本发明能够并行使用多种语言的字符串并且有助于其正确处理。

摘要： Aspects of the subject matter described herein relate database virtualization. In aspects, clusters of database servers may be located at various locations of the Internet. When a client seeks to access a logical database, the client may send a logical server and logical database name in a data structure. These names may be used to find a physical server(s) and database(s) that correspond to the logical database. Once the location is determined, a proxy component is used to intercept and/or forward communications between the client and the physical server(s) and database(s) corresponding to the logical database. Using this system, a client may access data from a logical database without knowing the physical address of the logical user database.

摘要： Object instance annotation technology is disclosed. This technology is capable of annotating any number of instances for any number of objects. Object instance annotations can be of various types, and annotations can serve as data extensions. Objects are enabled for annotation either by developers, or, alternatively, automatically by a programming language or framework. Furthermore, an interface is provided for annotations. This interface has a variety of operations, some of which allow for adding, retrieving, or removing annotations. Annotations can be reference types or even value types. They may also be private class types. Once object instances are enabled for annotating, and the interface is set up, this interface can annotate a multitude of different kinds of objects. For example, it can annotate generic objects, XML trees, CodeDom trees, and so on.

摘要： An optimizer/normalizer is used to generate optimized intermediate language representation of an input query, such as an XML input query. A method of optimization of an input query in intermediate language form includes receiving the input query, examining the nodes in a left-depth first manner to identify code patterns and node types which are subjects for optimization, tagging the identified code patterns until the intermediate language representation of the input query has been examined in its entirety, searching from the top of the intermediate language representation for tagged code patterns, and adjusting the tagged code patterns with improved code patterns to form an optimal representation for an input query. The input to the optimizer/normalizer is assumed to be an input query transformed into an intermediate language representation containing code patterns and nodes, each node having a respective node type.
