摘要： An improved type inference may be calculated for a path expression that may be classified into a series of input expressions followed by steps. For each such series, the inference may be calculated based on input including a type for the input expression, an axis for the step, and a node test for the step. The cardinality of the input expression type is preserved for the calculation of the step type. Also, a set of one or more matching node types may be identified within the type repository. These matching node types are node types within the axis of the step that match the node test of the step. These matching node types are identified without calculating the full content type implied by the axis. Avoiding the calculation of the full content type of the axis may reduce the processing time required to perform the inference.
摘要翻译：可以针对路径表达式计算改进的类型推断，其可以分为一系列输入表达式，随后是步骤。对于每个这样的系列，可以基于包括输入表达式的类型，步骤的轴和该步骤的节点测试的输入来计算推断。保留输入表达式类型的基数用于计算步骤类型。而且，可以在类型储存库内识别一组一个或多个匹配节点类型。这些匹配节点类型是与步骤的节点测试匹配的步骤的轴中的节点类型。识别这些匹配节点类型，而不计算轴所隐含的完整内容类型。避免计算轴的完整内容类型可能会减少执行推理所需的处理时间。

摘要： An extensible markup language (XML) expression included in a query is parsed to yield an abstract syntax tree. The abstract syntax tree is then transformed into a unified tree including XML algebra operations. The unified tree is then converted into a relational tree including enhanced relational algebra operations. The relational tree is then forwarded to a query processor for optimization and execution of the query at the query processor.

摘要： A computerized system and method for transforming the results of a query into a hierarchical information stream, such as an eXtensible Markup Language (XML) data stream is disclosed. A database server receives a query and generates a rowset. A rowset processor, using the mode specified in the query, processes the rowset and query to generate the XML data stream. For the “auto1” mode, the rowset processor transforms a rowset into an XML data stream using primary-foreign key information specified in the query to determine nesting. For the “auto2” mode, the rowset processor transforms a rowset into an XML data stream using table ordering information included in the query to determine nesting. For the “explicit” mode, the rowset processor transforms a rowset into an XML data stream using the explicit organizational information specified in the query.

摘要： The present invention provides “XML Schema Collections” and methods and systems for using the same. XML data is typically stored as an XML instance, each of which should conform to a “schema” according to a desired goal. An XML schema provides identification and organization for the data supplied by an XML instance. XML Schema Collections are collections of one or more XML schema namespaces. An storage location designated for storage of XML data, such as an XML column in a relational database, can be “typed” with an XML Schema Collection object, allowing that storage location to store XML instances that conform to more than one XML schema. XML Schema Collections provide increased data storage versatility, and facilitation of data searches.
摘要翻译：本发明提供了“XML Schema Collections”及其使用方法和系统。 XML数据通常存储为XML实例，每个实例都应符合所需目标的“模式”。 XML模式提供了由XML实例提供的数据的标识和组织。 XML Schema Collections是一个或多个XML模式命名空间的集合。指定用于存储XML数据的存储位置（如关系数据库中的XML列）可以使用XML Schema Collection对象“打入”，从而允许存储位置存储符合多个XML模式的XML实例。 XML模式集合提供增加的数据存储多功能性，并促进数据搜索。

摘要： Storing and querying XML data in a primary table or document utilizes an index of XML data and includes creating a primary table structure, creating a primary XML index commensurate with the primary table structure, populating the primary table and the primary XML index, and running a query on the XML data in a primary table by utilizing the XML index. The XML index can be implemented as a node table. The node table may have a B+-tree structure and be populated by shredding the XML values in the primary table. The XML data may be stored as binary large objects in an XML column of the primary table. Secondary XML indexes may be created to assist in the search and retrieval of XML data stored in the primary table. Both the primary XML index and the secondary XML index tables may be created using data definition language statements.

摘要： Several embodiments of the present invention are directed to systems and methods for extending the UDT framework of an extended relational data store (ERDS) to include support for unordered collections (multisets) and ordered collection (lists). More specifically, several embodiments of the present invention use an UDT infrastructure, CLR generics, and a new UNNEST operator to create and utilize a special type abstraction for collections that is simultaneously a scalar and a relation. As a scalar, this collection type can be processed by all parts of the data store engine that understand scalars (including but not limited to the client stack) and, as a relation, this collection type is queriable like any other type of relation.

摘要： Improved query optimizer using implied predicates. The system facilitates allowing a query optimizing component to introduce into a query, extra predicates that facilitate the following: render the same results as the original query; are used as dictated by rules passed to the optimizing component—these rules specify whether the new predicate is an equivalence (that will substitute the old predicate) or an implication (in which the old predicate is preserved); are considered as cost-based alternatives, and discarded if not useful; are tied to index utilization; and can consider both standard and multi-valued indices.
摘要翻译：改进了使用隐含谓词的查询优化器。该系统便于允许查询优化组件引入到查询中，另外的谓词便于执行以下操作：渲染与原始查询相同的结果; 根据传递给优化组件的规则使用这些规则 - 这些规则指定新谓词是否是等价性（将替代旧谓词）或暗示（其中保留旧谓词）; 被认为是基于成本的替代品，如果不是有用的话; 与指数利用挂钩; 并且可以考虑标准和多值指数。
