    摘要: Systems, methods, and other embodiments associated with providing query modes for translation-enabled XML documents are described. One method embodiment includes receiving an XPath query to an XML document that may store a translation for a data element. The method embodiment may also include automatically selecting a query mode for the XPath query. The method embodiment may also include querying the XML document using the XPath query and the selected query mode. The query mode may control, at least in part, the operation of an XML database logic.

    摘要: Described herein is a system for “lazy” manifestation of XML documents. In lazy manifestation, only portions of an XML document that contain data of interest (e.g., a particular element or attribute requested by an application) are manifested. The term “manifesting a portion of an XML document” refers to creating an in-memory representation of the portion and incorporating it into existing in-memory representation of an XML document, if any. These portions are referred to herein as a loadable unit. A loadable unit is a set of one or more nodes in an XML document, where when there is need to manifest a node in the set, other nodes in the loadable unit are manifested too. Loadable units may, but not necessarily, correlate to content structures that store the nodes. A loadable unit may be the nodes whose content is contained in a row.

    摘要: Techniques are provided for encoding/decoding binary XML data in a client program before sending/receiving the XML to/from a database server. By encoding the binary XML at the client, the overhead of parsing the XML text is avoided by the database server, thus improving database server scalability. Also, the XML data is sent by the server to the client in the binary form, and the binary format is decoded by the client program to perform the necessary operations.

    摘要: A database server determines, on an element-level of granularity, what form of VARRAY storage to map collections of elements defined by a XML schema. A collection element may be mapped to an in-line VARRAY or an out-of-line VARRAY. The determination may based on a variety of factors, including the database type mapped to the collection element, database limitations that limit the form storage for certain database types, and annotations (“mapping annotations”) embedded within that XML schema that specifying a database type for database representation of a collection element or a form of VARRAY storage.

    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。
