摘要： Architecture that maps document data (e.g., XML-extended markup language) into columns of one table, thereby avoiding schema normalization problems through special data storage. Moreover, an algorithm is described that can translate a query (e.g., in XPath (XML path language), a query language for navigating through document elements and attributes of an XML document) into a relational algebra query of the document column representation. Based on the characteristics of the new mapping, query rewriting rules are provided that optimize the relational algebra query by minimizing the number of joins. The mapping of XML documents to the table is based on a summary structure and a hierarchical labeling scheme (e.g., ordpath) to enable a high-fidelity representation. Annotations are employed on the summary structure nodes to assist in mapping XML elements and attributes to the table.
摘要翻译：将文档数据（例如，XML扩展标记语言）映射到一个表的列中的架构，从而通过特殊数据存储来避免模式规范化问题。此外，描述了可以将查询（例如，XPath（XML路径语言），用于浏览文档元素和XML文档的属性的查询语言）转换为文档列表示的关系代数查询的算法。基于新映射的特征，提供查询重写规则，通过最小化联接数来优化关系代数查询。将XML文档映射到表是基于总结结构和分层标签方案（例如ordpath）来实现高保真度表示。在摘要结构节点上使用注释来帮助将XML元素和属性映射到表中。

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对象进行输入，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： Modifying a portion of an XML document stored in a relational database includes converting operations on the document into an operator tree. The operator tree includes a first operator corresponding to a first portion of the schema for the modified data and a second operator corresponding to a parent portion of the schema for the modified data. A first and a second portion of the schema are extracted from the overall document schema. A first validation of the modified data using the first operator with the first portion of the schema is performed. This forms a partially validated XML document portion. Next, a second validation of the partially validated XML document portion with the second portion of the schema is performed using the second operator. The XML document constraints are verified and the modified data is merged into the XML document, thus avoiding a full validation of the XML document when certain XML Schema types are absent in the modified data.

摘要： Caching architecture that facilitates translation between schema data and relational structures. A schema translation component consumes schema data (e.g., XML schema data) having a schema structure. The schema structure is shredded into tables. A validation component interfaces to a memory management interface to facilitate loading only the necessary components to perform instance validation. During validation, only parts of the schema that are used are loaded and cached. A schema cache stores the in-memory representation of the schema optimized for instance validation. The schema components are loaded from metadata into the cache memory as read-only objects such that multiple users can use the in-memory objects for validation.

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： Translation architecture that facilitates translation between schema data and relational structures. The architecture includes a translation component that consumes schema data (e.g., an XML schema) that includes a schema structure, validates the schema structure, and persists in memory a representation of the schema as a relational format. Since schemas are shredded into tables, instance validation loads only the necessary components to perform validation. During validation, only parts of the schema that are used are loaded and cached. A schema cache stores the in-memory representation of schema optimized for instance validation. Schema components are loaded from metadata into main memory as read-only objects such that multiple users can use the in-memory objects for validation, query processing, query optimization and storage optimization of XML instance data
