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。

摘要： A method for storing XML documents a hybrid navigation/streaming format is provided to allow efficient storage and processing of queries on the XML data that provides the benefits of both navigation and streaming and ameliorates the disadvantages of each. Each XML document to be stored is independently analyzed to determine a combination of navigable and streamable storage format that optimizes the processing of the data for anticipated access patterns.

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： A method and apparatus for processing a file system operation at a database server is provided. A request to perform a file system operation on a resource stored in a database is received at a database system. The request may be implemented using the NFS protocol. The request may include state identification data that identifies state information associated with the request. State information associated with the request is retrieved within the database system based on the state identification data. State information is information that describes the operational state of the requestor for a particular file. The request is then processed based, at least in part, on the state identification. File system operations may be processed a database management system to access any data, such as a file, relational data, and object-relational data.

摘要： A method and apparatus for performing file system operation locks at a database server is provided. A request to perform a file operation on a portion of a file managed by a database server is received at the database server. In response to receiving the request, the database server grants a lock that covers only a portion of the file that is involved in the file operation. For example, the database server may grant a lock that covers a range of bytes on the file, where the range of bytes is less than the entire file. Thereafter, the database server performs the file operation on the file. The file operation may be a NFS operation.

摘要： An XML document can be represented in a compact binary form that maintains all of the features of XML data in a useable form. In response to a request for a modification (e.g., insert, delete or update a node) to an XML document that is stored in the compact binary form, a certain representation of the requested modification is computed for application directly to the binary form of the document. Thus, the requested modification is applied directly to the persistently stored binary form without constructing an object tree or materializing the XML document into a corresponding textual form. Taking into account the nature of the binary form in which the document is encoded, the bytes that actually require change are identified, including identifying where in the binary representation the corresponding actual changes need to be made.

摘要： A method and apparatus for loading an XML document into memory is provided. A client loads one or more array elements into a first partition of an array that is maintained in memory. Each array element represents an XML element of an XML document. Upon determining that an amount of data maintained in the first partition exceeds a first threshold, the client subsequently loads array elements into a new partition of the array. Upon determining that an amount of data maintained in the memory of the client exceeds a second threshold, the array elements of the least recently used partition are persistently stored in a database without persistently storing the entire XML document. When the last XML element of the XML document is loaded into a partition of the array, that partition is persistently stored in the database, thereby causing the entire XML document to be stored in the database.

摘要： Techniques are provided for indexing XML documents. According to one embodiment, a PATH table created for storing one row for each indexed node of the XML documents. The PATH table row for a node includes (1) information for locating the XML document that contains the node, (2) information that identifies the path of the node, and (3) information that identifies the position of the node within the hierarchical structure of the XML document that contains the node. If the node is associated with the value, then the PATH table row for the node may also include the value. Use of the PATH table to answer XPath queries is facilitated by secondary indexes.

摘要： Systems, methods, and other embodiments associated with providing an XML-based translation service are described. One method embodiment includes accessing a translation-aware XML document that may comply with a translation-enabling XML schema. The document may store a first XML element that stores translatable data and a second XML element that stores a translation of the translatable data. The schema may describe that the first XML element includes a first identifier that identifies the first element as storing translatable data. The schema may also describe that the second XML element includes a second identifier that identifies the second element as storing a translation for translatable data. The method may also include establishing a session language identifier and providing a virtual view of the translation-aware XML document, the virtual view being determined, at least in part, by the session language identifier.
