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.
摘要翻译：提供了一种用于将XML文档加载到存储器中的方法和设备。客户端将一个或多个数组元素加载到内存中维护的数组的第一个分区中。每个数组元素表示一个XML文档的XML元素。在确定第一分区中维持的数据量超过第一阈值时，客户端随后将阵列元素加载到阵列的新分区中。在确定客户端的存储器中保存的数据量超过第二阈值时，最近最少使用的分区的数组元素被永久地存储在数据库中，而不是持久地存储整个XML文档。当XML文档的最后一个XML元素被加载到数组的分区中时，该分区将永久存储在数据库中，从而导致整个XML文档存储在数据库中。

摘要： Techniques for managing XML data in an SQL compliant DBMS include receiving an SQL statement. The SQL statement includes a particular operator that operates on a first instance of XML type that represents a first set of XML elements. During execution of the SQL statement, the particular operator is evaluated by generating an ordered collection of instances of XML type. Each different instance in the ordered collection is based on a different XML element from the first set; and there is an instance in the ordered collection for every XML element from either the first set or from the first set and its descendents. When descendents are included, each entry in the ordered collection indicates a level in the XML tree. In another aspect, an aggregate operator in the SQL statement operates on a collection of instances, with associated levels, to generate a single instance of XML type.
摘要翻译：在SQL兼容DBMS中管理XML数据的技术包括接收SQL语句。 SQL语句包括一个特定的操作符，它在代表第一组XML元素的XML类型的第一个实例上运行。在执行SQL语句期间，通过生成XML类型的实例的有序集合来评估特定的操作符。有序集合中的每个不同实例都基于与第一个集合不同的XML元素; 并且有序集合中的第一个集合或第一个集合及其后代的每个XML元素都有一个实例。当包含后代时，有序集合中的每个条目指示XML树中的一个级别。另一方面，SQL语句中的聚合运算符对具有关联级别的实例集合进行操作，以生成单个XML类型的实例。

摘要： Techniques for supporting access controls on application-specific operations performed by an application include receiving first data at a server distinct from the application. The first data describes a first set of privileges for performing a first set of application-specific operations. Second data is also received at the server. The second data associates a first user of the application with a privilege in the first set of privileges. In response to receiving a request at the server from the application, it is determined whether a particular user may have the application perform a particular application-specific operation based on the first data and the second data. The request indicates the particular user and the particular application-specific operation. A response is sent to the application. The response indicates whether the particular user may have the application perform the particular application-specific operation.

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 hierarchy may be explicitly or implicitly reflected in existing data maintained external to hierarchy structures. Such hierarchies are referred to herein as a "pre-existing hierarchies". Techniques are described herein for capturing a pre-existing hierarchy in hierarchy structures. After a pre-existing hierarchy has been captured, there exist two independent sets of data that reflect the hierarchy: the external hierarchy definition and the internal hierarchy definition. Changing either hierarchy definition changes the hierarchy. Therefore, to maintain a consistent reflection of the hierarchy, the internal hierarchy definition must be modified in response to changes made to the external hierarchy definition, and the external hierarchy definition must be modified in response to changes made to the internal hierarchy definition. Various techniques are described for maintaining consistency between the two hierarchy definitions.

摘要： Direct memory accessed is used to perform database operations between two or more machines. A first segment of memory is allocated for a second machine, where at least one of the first machine and second machine is a database server. During performance of a database operation that involves the transfer of data from the second machine to the first machine, data in the first segment of memory is buffered in response to the second machine writing the data to a second segment of memory on the second machine.

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： Techniques are provided for one or more portions of the relational database to visualized as an XML document. A standard Uniform Resource Locator (URL) mechanism is provided to access data stored in the relational database by defining the URL as an XPath expression over the visualized XML document. Techniques are provided for mapping XML data and metadata from data in relational databases, for allowing the user to use a database query to retrieve data from a relational database in the form of XML documents, and for XML data storage and query rewrites in relational databases.
