摘要： A method and apparatus for more efficiently storing shredded XML documents is provided. The method and apparatus exploit the power of compression and a form of storing relational data referred to as column-major format, to store XML documents in shredded form. The column values that are to be stored for shredded XML documents are separately analyzed for each XML document to determine whether to store a particular column in column-major format and what compression technique to use, if any.

摘要： A method and system are provided for extracting a valid, self-contained fragment for a node in a XML document stored in a database management system. An XML index is used to identify a location in which XML fragment data corresponding to the node is located. Ancestors of the node are identified and examined for any information needed for the proper interpretation of the fragment. If an ancestor node contains such needed information, this information is patched into the XML fragment to ensure that the fragment is a valid, self-contained XML fragment.

摘要： A method and system are provided for determining whether a given path is an indexed path of XML documents stored in a database management system. A finite state machine is built using the path subsetting rules specified by a user. The finite state machine is traversed using the given path. If any accepting states are reached during the traversal of the finite state machine, the given path is determined to matching the path subsetting rules.

摘要： A method and system of handling document operation requests on documents with large collections and constrained memory is disclosed. In some embodiments, when one or more collection elements of a document are required to be in memory for a document operation, each of the one or more required collection elements not already in the memory are loaded into a collection partition in the memory before the document operation is executed.

摘要： Techniques for accessing data that resides in a document on a computer-readable medium by a device with device resources of limited resource amount include determining usage for each portion of the document that consumes the device resources of a plurality of portions of the document. Each portion may be accessed independently of a different portion of the document. Based on the usage, a particular portion of the document is selected to cease consuming the device resources. The device resources consumed by the particular portion are released. The techniques allow a document-processing device with limited resources to scale up to process a large document that would otherwise exceed the available resources. This capability is an advantage when first inserting a large XML document, which cannot be fully manifested in available memory, as multiple loadable units into a database or other persistent store.

摘要： A method and apparatus is provided for translating queries, such as path expressions and SQL/XML constructs, into SQL statements to be executed against an XML index, which improves processor time as opposed to applying path expressions directly to the original XML documents to extract the desired information. Simple path expressions, filter expressions, descendant axes, wildcards, logical expressions, relational expressions, literals, and other path expressions are all translated into SQL for efficient querying of an XML index. Similarly, rules for translating SQL/XML constructs into SQL are provided.
摘要翻译：提供了一种方法和装置，用于将诸如路径表达式和SQL / XML结构之类的查询转换为针对XML索引执行的SQL语句，这样可以提高处理器时间，而不是将路径表达式直接应用于原始XML文档来提取所需信息。简单的路径表达式，过滤器表达式，后代轴，通配符，逻辑表达式，关系表达式，文字和其他路径表达式都被转换为SQL，以便有效地查询XML索引。同样，提供了将SQL / XML结构转换为SQL的规则。

摘要： A method and system for the in-place evolution of XML schemas is disclosed. To automatically evolve an existing XML schema, a schema evolver receives both an existing XML schema and an XML document as input. The XML document indicates changes to be made to the existing XML schema. Based on the existing XML schema and the XML document, the schema evolver evolves the existing XML schema into a new XML schema that incorporates the changes indicated in the XML document. According to one aspect, the schema evolver generates one or more SQL statements based on the new XML schema. The SQL statements, when executed by a database server, cause the database server to evolve database structures that were based on the formerly existing XML schema so that the database structures conform to the new XML schema. This is accomplished "in place," without copying the data in the database structures.
摘要翻译：公开了一种用于XML模式的就地演化的方法和系统。为了自动演进现有的XML模式，架构演进程序接收现有的XML模式和XML文档作为输入。 XML文档指示对现有XML模式进行的更改。基于现有的XML架构和XML文档，架构演进者将现有的XML架构演变为新的XML架构，其中包含XML文档中指示的更改。根据一个方面，模式演进者基于新的XML模式生成一个或多个SQL语句。 SQL语句在由数据库服务器执行时，会导致数据库服务器发展基于以前存在的XML模式的数据库结构，以便数据库结构符合新的XML模式。这完成了“到位”，而不复制数据库结构中的数据。

摘要： Techniques for managing multiple hierarchies of data from a single native hierarchy include registering a set of routines for each foreign hierarchy. The set of routines performs a set of operations on data in the hierarchy associated with a node. A user request is received, which indicates a particular operation on particular data that does not correspond to a node of the native hierarchy. Based on the user request, a first operation on a first set of one or more nodes of a first hierarchy that is not the native hierarchy is determined. A particular routine that corresponds to the first operation is selected from a first set of routines registered for the first hierarchy, and is invoked. These techniques allow a user to employ a consistent interface with the native hierarchy to reach data in any of the hierarchies.

摘要： A method and system are provided for allowing users to register XML schemas in a database system. The database system determines, based on a registered XML schema, how to store within the database system XML documents that conform to the XML schema. This determination involves mapping constructs defined in the XML schema to constructs supported by the database system. Such constructs may include datatypes, hierarchical relationship between elements, constraints, inheritances, etc. Once the mapping has been determined, it is stored and used by the database system to determine how to store subsequently received XML documents that conform to the registered XML schema.

摘要： Techniques are provided for ensuring lexical fidelity when an XML document is stored in a binary format. Operations, on the XML data, that would cause the loss of lexical fidelity between the original XML document and the binary-encoded version of the XML document are not performed. Such operations include the removal of unnecessary whitespace characters, certain data type conversions, CRLF normalization, the "collapsing" of two-tag empty elements into a single tag empty element, and the replacing of entity references or numeric character references with another value. An XML schema, to which the XML document conforms, may indicate that the XML document is to be stored in a lexical fidelity mode. Additionally, or alternatively, the database statement that (when executed) causes the XML document to be stored in a binary format may so indicate.
摘要翻译：当XML文档以二进制格式存储时，提供了用于确保词汇保真度的技术。不会执行对原始XML文档和XML文档的二进制编码版本之间的词法保真度的XML数据的操作。这样的操作包括删除不必要的空白字符，某些数据类型转换，CRLF归一化，将双标签空元素“折叠”到单个标签空元素中，以及用另一个值替换实体引用或数字字符引用。 XML文档符合的XML模式可以指示XML文档将以词法保真模式存储。另外或替代地，数据库语句（当被执行时）导致XML文档以二进制格式存储可以这样表示。
