摘要： A method and apparatus for estimating the cost of streaming evaluation of XPaths is provided. Aggregate statistics are maintained by the database server upon initiation of a database function by the database administrator about the nodes of the XML document. Based upon these statistics and the complexity of the particular XPath query, an estimate of the cost of the query, in time and computing resources required, is computed.

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： A method and apparatus for efficiently processing a query that specifies a location path and a content path is provided. The location path identifies the hierarchical location of a set of documents within a resource hierarchy. The content path identifies hierarchical location of one or more nodes within the content of the set of documents. Computing the query includes using a resource hierarchy index, based on the location path, to generate first results corresponding to the set of documents. Computing the query also includes using a content index, based on the content path, to generate second results corresponding to the one or more nodes. Final results of the query are based on the first results and second results by, for example, joining the first and second results.
摘要翻译：提供了一种用于有效地处理指定位置路径和内容路径的查询的方法和装置。位置路径标识资源层次结构中一组文档的分层位置。内容路径识别文档集合内的一个或多个节点的分层位置。计算查询包括使用基于位置路径的资源层次索引来生成与该组文档相对应的第一结果。计算查询还包括使用基于内容路径的内容索引来生成对应于一个或多个节点的第二结果。查询的最终结果基于第一个结果和第二个结果，例如，加入第一个和第二个结果。

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.
摘要翻译：提供了在向/从数据库服务器发送/接收XML之前，在客户端程序中对二进制XML数据进行编码/解码的技术。通过在客户端编码二进制XML，数据库服务器可以避免解析XML文本的开销，从而提高数据库服务器的可伸缩性。此外，XML数据由服务器以二进制形式发送给客户端，二进制格式由客户端程序解码以执行必要的操作。

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：提供了一种将XML文档加载到存储器中的方法和装置。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XML文档的XML元素。在确定在第一分区中维护的数据量超过第一阈值时，客户端随后将数组元素加载到阵列的新分区中。在确定在客户端的存储器中维护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持久地存储在数据库中，而不会持续存储整个XML文档。当XML文档的最后一个XML元素加载到数组的分区中时，该分区将永久存储在数据库中，从而使整个XML文档存储在数据库中。

摘要： A compact binary encoding technique for information that is logically hierarchically structured, such as XML data, maintains all of the features of XML data in a useable form, such as the hierarchical structure underlying the data. Hence, data encoded in this format can undergo XML-based processing on-the-fly as it is being received or fetched, as if the data was being processed linearly in its textual character-based format. Processing of data encoded in this format can begin without having to wait for and decode the entire data set. The overhead due to XML tags is significantly minimized. The encoded data can be processed more efficiently because the data is pre-parsed. Values may be stored in their native type formats and, therefore, processing of the encoded data avoids costly type conversions. Further, any available structural constraint information can be effectively exploited.
摘要翻译：用于逻辑分层结构的信息（如XML数据）的紧凑二进制编码技术以可用的形式维护XML数据的所有功能，例如数据的基础层次结构。因此，以这种格式编码的数据可以在接收或获取的情况下随时进行基于XML的处理，就好像数据以其基于文本字符的格式被线性处理。以该格式编码的数据的处理可以开始，而不必等待和解码整个数据集。由于XML标签引起的开销显着降低。可以更有效地处理编码数据，因为数据是预先解析的。值可以以其本机类型格式存储，因此，编码数据的处理避免了昂贵的类型转换。此外，可以有效地利用任何可用的结构约束信息。

摘要： A method and apparatus for facilitating the management of metadata is disclosed, specifically by associating metadata with an XML schema. The database system provides a method that allows end users to maintain additional information describing resources. User-defined metadata attributes are associated as an XML schema which in turn is mapped to a table, referred to as the user metadata table. The XML schema contains user-defined information specifying the metadata that the end-user wants the system to store and maintain. Additionally, a reference is created between an entry in the user metadata table and its corresponding resource entry in the resource table. The resources are accessed directly or by issuing queries against the user metadata table. The querying of the user metadata table gains the benefit of fast and efficient query results and access time.
