Abstract: A large capacity high dimensional data indexing device supporting high-expandability in a cluster environment and a method thereof are provided to filter content-based search about high dimensional data first by using a spill tree and perform parallel search by using a signature in each node, thereby supporting rapid performance. A spill tree generation unit(210) generates a spill tree by extracting a sample of an N-dimensional feature vector. A feature vector divided storage unit(220) dividedly stores the N-dimensional feature vector in a terminal node of the spill tree. A local signature generation unit generates a signature locally about the N-dimensional feature vector distributed into each node of the spill tree.

Abstract: A device and a method for processing continuous queries sharing a result of the queries for an XML(extensible Markup Language) data stream are provided to improve continuous query processing performance with reduction of repeated operation by sharing the result for common operation shared among the continuous queries. A syntax analyzer(520) checks a syntax error by receiving continuous queries registered from an external application/user(510), checks a semantic error of a syntax analysis result received from the syntax analyzer, and transfers a semantic analysis result. A semantic analyzer(530) checks a semantic error of the syntax analysis result received from the syntax analyzer and transfers the semantic analysis result. A sharable operation extractor(540) extracts operations sharable among a plurality of continuous queries and stores a result of the extracted sharable operation separately. A query executor(550) executes the continuous query for an XML data stream by using a sharable operation result while rounding the semantic analysis result and outputs the result to the outside.

Abstract: PURPOSE: A method for recovering for a high dimensional index structure is provided to secure an efficient recovery in a reinsertion calculation based on an ARIES(Algorithm for recovery and isolation exploiting semantics) and a page-oriented re-performing and a page-oriented recovery. CONSTITUTION: An "NTA" is started for recovering a deletion of one reinsertion entry(200). The number of remaining entries which are not inserted in a node to be performed a recovery are read, and the entries are inserted in a node to be performed a recovery as the number of entries which are not inserted and remains out of the deleted entries which are recorded in a log record. In addition, a log record in the case that a partial or all reinsertion entries are inserted is recorded when a log record is recovered at a deletion of a reinsertion entry selected in a terminal or non-terminal node(201). After the entry is inserted, the changed minimum boundary area is reflected in an ancestor node(202), and the "dummyCLR" meaning that one recovery process of a reinsertion entry is completed is recorded(203), and the process is restored.
Abstract translation: 目的：提供一种恢复高维度索引结构的方法，以确保基于ARIES（恢复和隔离开发语义的算法）和面向页面的重新执行和面向页面的恢复的重新插入计算中的有效恢复 。 构成：启动“NTA”以恢复一个重新插入条目（200）的删除。 读取未插入到要执行恢复的节点中的剩余条目的数量，并且将条目插入到要执行恢复的节点中作为未被插入并保留在删除条目之外的条目的数量 记录在日志记录中。 此外，当在终端或非终端节点（201）中选择的重新插入条目的删除中恢复日志记录时，记录插入部分或所有重新插入条目的情况下的日志记录。 在插入条目之后，改变的最小边界区域被反映在祖先节点（202）中，并且记录表示重新插入条目的一个恢复处理完成的“dummyCLR”（203），并且处理被恢复。

Abstract: PURPOSE: A cluster data management system and a method for data recovery using parallel processing thereof in a cluster data management system are provided to reduce the input/output of a disk in a reprocessing log access for data recovery by splitting a reprocessing log into rows of a partition. CONSTITUTION: A partition server(12-1 to 12-n) records a reprocessing log according to a service of a partition and is in the charge of a service for a partition. When an error happens in a partition server, a mater server(11) splits the reprocessing log into the rows of the partition and selects the partition server for reestablishing the partition based on the split reprocessing log. The mater server arranges the reprocessing log in an ascending order based on the reference information.
