摘要： In one embodiment, a database server registers one or more functions included in a user-defined index that includes one or more auxiliary properties. The one or more functions are operable to generate index entries of the user-defined index for the one or more auxiliary properties. The one or more auxiliary properties are different than, and in addition to, a primary property of the user-defined index that provides for evaluating a query operator. The database server receives a first statement that defines the user-defined index, where the first statement includes one or more parameters that define the one or more auxiliary properties. The database server invokes the one or more functions in response to the first statement, where the one or more functions when invoked generate and store the index entries of the user-defined index according to the one or more parameters that define the one or more auxiliary properties.

摘要： A method and apparatus for rewriting a database command containing an embedded XML expression such that the rewritten database command recites a text function, in lieu of the embedded XML expression, is provided. Advantageously, a DBMS may take advantage of the efficiencies in storing XML data within the database, while avoiding the generation of unnecessary XML elements in processing the query when the XML elements contribute nothing to the outcome of the query. Cost-base or rule-based analysis may be performed to determine how to rewrite a received database command. The database server may functionally evaluate the text function or may use an index defined on a column of the database. The text function may function as a primary filter or may reference a column upon which an index is defined, wherein the index operates at the same or higher level than a column being referenced in the embedded XML expression.
摘要翻译：提供一种用于重写包含嵌入式XML表达式的数据库命令的方法和装置，使得重写的数据库命令背景文本功能代替嵌入的XML表达。有利地，DBMS可以利用在数据库中存储XML数据的效率，同时避免在XML元素对查询的结果没有贡献时在处理查询时生成不必要的XML元素。可以执行基于成本或基于规则的分析来确定如何重写接收到的数据库命令。数据库服务器可以在功能上评估文本功能，或者可以使用在数据库的列上定义的索引。文本函数可以用作主过滤器，或者可以引用定义索引的列，其中索引在与嵌入式XML表达式中引用的列相同或更高的级别上操作。

摘要： The present invention discloses a memory device with a leakage current reduction feature. The memory device includes at least one memory cell for storing a value, and at least one switch module coupled to the memory cell for generating an operating voltage at various levels depending on various operation modes of the memory cell. The operating voltage is at a first level when the memory cell is being accessed, and is at a second level lower than the first level when the memory cell is not being accessed, thereby reducing a leakage current for the memory cell.

摘要： Systems, methods, and other embodiments associated with real-time text indexing are described. One example method includes receiving a document for indexing in a search system that includes a mature index and indexing the received document in a staging index. The staging index may be stored in direct access memory associated with query processing that does not degrade query performance even when postings become fragmented. The staging index and the mature text index are accessed to process queries on the search system. The example method may also include periodically merging the staging index into the mature index based on query feedback.

摘要： Techniques are provided for searching within a collection of XML documents. A relational table stores an entry for each node of a set of nodes in a collection of XML documents. Each entry of the relational table stores an order key and a path identifier along with the atomized value of the node. Instead of storing the atomized value in a full-text index, a virtual column can be created to represent, for each node, the atomized value of the node. Alternately, each entry of the relational table stores an order key and a path identifier along with, for simple nodes, the atomized value, and for complex nodes, a null value. For a complex node with a descendant text node, a separate entry is stored for the descendant text node in the relational table.

摘要： A method and apparatus for processing a query is provided. A query for a set of Matching XML documents is received. A client may transmit the query for a set of XML documents to the database server. The database server transmits a request for the set of XML documents to a persistent storage. The persistent storage uses an index, at least in part, to obtain the set of XML documents sought by the query. The index stores a first set of entries comprising information about the location of elements, a second set of entries comprising information about element attributes, and a third set of entries comprising information about element values. In responding to a particular query, additional XML documents that are not indexed by the index may also be checked to determine if they correspond to the set of search criteria.
