摘要： A method for converting relational data to XML (eXtensible Markup Language) is provided. The method can use a greedy algorithm to efficiently construct materialized XML views of relational databases. A greedy algorithm designed for XML view definition queries is provided for decomposing a large query into smaller queries and determining which query will run faster without actually running the query.

摘要： A method for converting relational data to XML (Extensible Markup Language) is provided. The method, sometimes referred to as SilkRoute, provides a general, dynamic and efficient tool for viewing and querying relational data in XML. SilkRoute can express mappings of relational data in XML that conforms to arbitrary public document type definitions. Also, SilkRoute can materialize the fragment of an XML view needed by an application and it can fully exploit the query engine of a relational database management system whenever data items in an XML view need to be materialized.

摘要： An apparatus and method for efficiently processing a database. A structure of the database is constructed into a schema which only includes those structures of the database that are known. Desired information to be extracted from the database is specified using path expressions and an automaton models the path expression. A composite automaton is generated based on the automaton and the schema. The composite automaton is pruned and portions of the database corresponding to the pruned automaton is searched to obtain the desired information. Points within the database may be identified to begin searching for the desired information. These points correspond to states of the composite automaton. A hybrid automaton may be formed for each set of possible starting states to determine completeness by simulating the hybrid automaton against the composite automaton.

摘要： A method and apparatus for managing a web-site. An information definition query is received for defining an integrated view of non-uniform information retrieved from a multiple sources across a network, and stored in multiple formats. An integrated view is created according to the information definition query. A site definition query is received for defining a site view for the non-uniform information at the web-site. The site view is created according to the site definition query. The non-uniform information is then presented on the web-site, typically in the form of a HTML document.

摘要： A technique for performing query evaluation on distributed directories utilizes the creation of a “topology cache” defining the hierarchical relationship between the various directory servers (i.e., identifying “subordinate” and “superior” knowledge references associated with each directory server in the system). The created topology cache is then stored at each directory server, and forwarded to a client upon submitting a query to the system. Using the topology cache information at the client, a distributed query evaluation plan can be developed for use with complex queries, such as hierarchical and aggregate queries.

摘要： A method and apparatus provides for efficient view maintenance of query of a database. The database is represented by an edge-labeled tree which is decomposed into a plurality of portions based on an automaton modeling an original query. When an addition to the database occurs, it is first determined which portion of the database the addition is made. Then an update query is performed on the added portion. The update query is determined by selecting a state corresponding to a portion as a root state and ignoring all previous states and transitions. The update query is applied to the portion of the database that the addition is made. The result of the update query is incorporated with the results of the query to produce an updated view.

摘要： An apparatus and method for restructuring a database modeled by an edge-labeled tree. Portions of an output tree is generated by matching patterns of tree elements of a starting tree. Portions of the output tree are combined to form a complete output tree which may be restructured again until a final output tree presents a desired "view" of the starting database. If the pattern matches used in restructuring the starting tree is restricted to attributes of tree elements that only includes preceding edge information, successive tree restructuring may be composed into a single restructuring process that optimizes the restructuring by taking advantage of restructuring results of each of the original restructuring processes.
摘要翻译：一种用于重组由边缘标记树建模的数据库的装置和方法。通过匹配起始树的树形元素的模式来生成输出树的部分。输出树的部分被组合以形成完整的输出树，其可以重新重构，直到最终输出树呈现起始数据库的期望的“视图”。如果重构中使用的模式匹配，则起始树被限制为仅包括先前边缘信息的树元素的属性，连续的树重组可以被组合成单个重组过程，其通过利用每个原始的重构结果来优化重组重组流程。

摘要： The occurrence of recursive loops between network elements are detected and prevented. One or more queries are generated that are sent between the network elements. One or more of the network elements detect the imminent occurrence of a recursive loop between the network elements, and prevent the recursive loop by generating an intensional answer in response to the query. The intensional answer contains rules.

摘要： A method and apparatus for applying a query to a database that is distributed into first portions. The query is first partially performed by terminals each containing one of the first portions. The results of the partial queries are recombined in such a way as to minimize the traffic among the terminals connected across networks. Paths of an edge-labeled tree representing the database connecting the first portions are expanded into subpaths corresponding to all the states of an automaton modeling the query. The database is distributed into second portions based on the automaton. Non-existing subpaths are ignored based on the automaton and which of the second portions the paths exit. Thus, the data transferred among first portions are minimized and the query process is optimized.
