摘要： A method and apparatus for processing path-based database operations is provided. According to one aspect, a path cache is maintained. For each hierarchical node that is traversed during a path-determining operation, it is determined whether a cache entry corresponding to that node is already contained in the path cache. If such a cache entry is already contained in the path cache, then the path indicated in that cache entry is used to complete the pathname for the node for which the operation is being performed. As a result, hierarchically higher nodes do not need to be traversed to complete the operation. Alternatively, if such a cache entry is not already contained in the path cache, then a cache entry for the node currently being traversed is generated and inserted into the path cache for use in subsequent path-determining operations.

摘要： A method and system are provided for flexibly sectioning XML documents stored in a relational database system. The method includes obtaining a set of sectioning rules; receiving an XML document that is to be stored in the relational database system; and identifying a storage location for each node in the XML document based on the set of sectioning rules. The sectioning rules can also be used to determine which tables in the relational database should be queried when a query is received, and to determine which tables in the relational database should be updated when a command to update stored XML data is received.

摘要： An XPath expression is converted into a tree-based representation where each node represents an operation to be performed and the links between nodes in the tree represent the flow of data between operations. The conversion may involve creating a parse tree for the XPath expression, and then converting the parse tree into an operator tree. The operator tree is constructed in such a way that execution of the XPath expression begins at the leaf nodes of the operator tree, and the results are then passed up the tree. After each node is executed, the results are either (1) passed to a filter that filters the results with a predicate statement or (2) passed to another node to be operated upon. This occurs until no nodes remain to be executed.
摘要翻译： XPath表达式被转换为基于树的表示，其中每个节点表示要执行的操作，并且树中的节点之间的链接表示操作之间的数据流。转换可能涉及为XPath表达式创建解析树，然后将解析树转换为运算符树。运算符树的构造方式是在运算符树的叶节点处开始执行XPath表达式，然后将结果传递给树。在执行每个节点后，结果将被传递给过滤器的过滤器，该过滤器使用谓词语句或（2）传递给另一个要运行的节点的结果。直到没有节点保持执行才发生。

摘要： Techniques for servicing requests for database services include maintaining at a database server an available set of one or more database session data structures. Each database session data structure holds information to support one session of one or more requests for database services over a communication connection that persists for one or more communications from one client. A database session data structure in the available set is not associated with any client currently connected to the database server. These techniques allow a database server to more efficiently service more numerous requests for database services, such as generated by communications using a stateless protocol like HTTP.

摘要： Disclosed is a method and mechanism for accessing XML data. In one approach, in the case of a schema based document, the structure of the XML document is known apriori and this information can be exploited to store and retrieve the data more efficiently. A Named Access interface or procedure can be defined and associated with elements of the schema. The need for datatype conversions can be eliminated by allowing direct mapping to the intended datatype or the closest matching datatype in the system to which the invention is directed. The storage information can be exploited to provide “direct” access to data based on offset in lieu of a linear traversal. Another aspect is that only the relevant portions need to be even loaded into memory.

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.

摘要： Efficient evaluation of resource version history queries is enabled by using a data container storing records corresponding to links between successive versions of a resource. The records include: (a) a record identifier, (b) a predecessor identifier, (c) a successor identifier, (d) a predecessor rowset, which comprises the record identifier of each record in which the predecessor identifier in this record is the successor identifier, and (e) a successor rowset, which comprises the record identifier of each record in which the successor identifier in this record is the predecessor identifier. Depending on the nature of a request, a record is identified in which a particular version is identified by either the predecessor identifier or the successor identifier. Either the predecessor or successor rowsets are recursively read, while the predecessor or successor identifiers corresponding to each record read are added to a result set, thereby forming the ancestor or descendant version history.
