摘要： The approaches described herein provide an efficient way to process certain kinds of queries that retrieve XML data stored in an object-relational database. A technique determines whether a query comprises a plurality of iteration expressions that exhibit a particular relationship to one another, and if so, re-writes the query and produces an optimized query execution plan. The query execution plan specifies an XPath-based row source with caching enabled. A very small cache structure is used, and reference locators are stored in the cache that point into binary-encoded data rather than copying XMLType data into the cache. Row data may be cached on the first use of the path-based row source and re-used in subsequent requests for rows. Once there is a subsequent request for rows from the optimized path-based row source, the cache may be reorganized to efficiently produce the rows of the row source.

摘要： A database system that incorporates numerous features that reduce the total cost of maintaining the database system is provided. That database system includes a database appliance that executes a database server on a platform that includes a special purpose operating system specifically tailored to the services required by the database server. The database appliance configures itself by detecting the environment in which it resides and setting operational parameters based on the detected environment. The configuration metadata of all components of the system are stored in a centralized repository which itself may reside external to the system. Both the database server configuration and the operating system configuration are managed by a remotely located integrated management console, which interacts with and configures the system at the database system level, the operating system level and, optionally, at the hardware subsystem level. Backup management may also be performed remotely. The remote components, such as the integrated management console, the backup server, and the configuration repository, may communicate with the system through a wide area network, such as the Internet, or directly through a dial-up connection.

摘要： A technique for differencing XML documents is provided. An edit graph is generated for computing the cost of possible edits that may be applied to a first XML document in order to generate a second XML document. A hash value is assigned to nodes included in the axes of the edit graph, where one axis includes nodes in the first XML document and the other axis includes nodes in the second XML document. The hash value may be generated based on a particular node's name and attributes, and the hash value of the name and attributes of each child node of the particular node. A technique for patching an XML document is also provided. Events are generated for each node in the input document and for at least one operation specified in the edit script. The edit script is applied to the input document by performing one or more operations specified in the operation events on one or more node events.

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能如此指示。

摘要： A mechanism is provided for improving the performance of particular database queries operating on a view comprising binary-encoded XML. The key to improving performance is to determine whether a XML index is available to improve the computation of XPath data before deriving an optimized execution plan for a particular query. When a XML index is not available to help expedite the computation of binary-encoded XML, then deferring the computation of the XPath data until after the view merge stage avoids unnecessary computation of XPaths that are part of the view but not needed for the particular query.

摘要： Techniques are described for preserving the original insignificant white space of XML data. The techniques may be used in combination with compact XML data storage formats, such as binary XML, to preserve the insignificant white space without requiring as much storage space as uncompressed formats. White space opcodes/operand pairs are described for representing white space characters and white space patterns. The white space opcode/operand pairs represent the white space in binary XML, are use to generate the original white space when the binary XML is decoded back to textual XML data.
