Abstract: A method, apparatus and system for rendering a web page. A webcore is included at a server side and a RenderServer is configured at a server side in advance. The RenderServer parses a received web page into a DOM tree and sends the received web page to the webcore. The webcore renders the web page to form a render tree. The RenderServer transforms data information corresponding to Render objects on the render tree into binary stream according to the DOM tree and sends the binary stream to the mobile terminal. The mobile terminal performs drawing operation for the binary stream to implement web page browsing.

Abstract: A method of searching a document having nested-structure document-specific markup (such as Extensible Markup Language (XML)) involves 112 receiving a query that designates at least (A) a phrase to be matched in a phrase matching process, and (B) a selective designation of at least a tag or annotation that is to be ignored during the phrase matching process. The method further involves 114 deriving query-specific indices based on query-independent indices that were created specific to each document, and 116 carrying out the phrase matching process using the query-specific indices on the document having the nested-structure document-specific markup.

Abstract: Embodiments of the present invention provide a method for processing a World Wide Web (WWW) page, which includes: determining at least one website to be optimized; generating a corresponding page template for each of WWW pages with different types in each website, and storing the page template; grabbing WWW pages from each website, matching each grabbed WWW page with a page template, filtering redundant HTML data from the WWW page according to a matching result, and storing the filtered WWW page; after receiving a request sent by a terminal for accessing a WWW page, determining whether there is a stored filtered WWW page corresponding to the WWW page requested by the terminal, if yes, returning the filtered WWW page to the terminal. Embodiments of the present invention also provide an apparatus for processing a WWW page. With the scheme of the present invention, redundant information may be efficiently eliminated.

Abstract: A system, method, and computer-readable medium for dynamic detection and management of data skew in parallel join operations are provided. Rows allocated to processing modules involved in a join operation are redistributed among the processing modules by a hash redistribution of the join attributes. Receipt by a processing module of an excessive number of redistributed rows having a skewed value on the join attribute is detected by a processing module which notifies other processing modules of the skewed value. Processing modules then terminate redistribution of rows having a join attribute value matching the skewed value and either store such rows locally or duplicate the rows. The processing module that has received an excessive number of redistributed rows removes rows having a skewed value of the join attribute from a redistribution spool allocated thereto and duplicates the rows to each of the processing modules.

Abstract: Techniques for fast loading data from an external distributed file system (DFS) to a database management system (DBMS) are provided. Assigning a portion of data from a file located in the DFS to each of a plurality of DFS clients. Configuring each DFS client to interact with a specific gateway from a plurality of gateways associated with the DBMS. Each gateway configured to send its portion of the file received from its designated client to every access module processor (AMP) controlled by that gateway. Each AMP processes a portion of the data received from the gateway to load the data into a table of the DBMS.

Abstract: Techniques for guided access to an external distributed file system (DFS) from a database management system (DBMS) are provided. A user access a graphical user interface (GUI) to interactively define a search on an external DFS. The search and any filtering conditions are processed on the external DFS and results are imported to the DBMS and mapped to a table in the DBMS for manipulation and access by the user within the DBMS.

Abstract: Techniques for accessing a parallel database system via an external program using vertical and/or horizontal partitioning are provided. An external program to a database management system (DBMS) configures external mappers to process a specific portion of query results on specific access module processors of the DBMS that are to house query results. The query is submitted by the external program to the DBMS and the DBMS is directed to organize the query results in a vertical or horizontal manner. Each external mapper accesses its portion of the query results for processing in parallel on its designated AMP or set of AMPS to process the query results.

Abstract: Techniques for data assignment from an external distributed file system (DFS) to a database management system (DBMS) are provided. Data blocks from the DFS are represented as first nodes and access module processors of the DBMS are represented as second nodes. A graph is produced with the first and second nodes. Assignments are made for the first nodes to the second nodes based on evaluation of the graph to integrate the DFS with the DBMS.

Abstract: Techniques for optimizing outer joins in database operations are provided. In an embodiment, a query having an outer join with a GROUP BY clause is rewritten and expanded to expand a first level partition of that GROUP BY clause to produce a modified query. In another situation, rows associated with processing a query are each row split and then hashed based at least in part on attributes of the outer join predicate. A left outer join is performed and a global aggregation processed to produce a spooled table to process the query.

Abstract: Techniques for external application-directed data partitioning in data exported from a parallel database management system (DBMS) are provided. An external application sends a query, a total number of requested access module processors (AMPs), and an application-defined data partitioning expression to the DBMS. The DBMS executes the query with the results vertical partitioned on the identified number of AMPs. Individual external mappers access their assigned AMPs asking for specific partitions that they are assigned to process the query results.

Abstract: A system, method, and computer-readable medium for optimized processing of queries that feature maximum or minimum equality conditions are provided. The disclosed mechanisms provide for a single-scan of the table on which the group-by query is applied. When the table is scanned, each processing module dynamically keeps track of the row(s) having a value of the attribute on which the equality condition is applied that equals or exceeds the maximum attribute value (assuming a maximum equality condition is applied) previously encountered by the processing module. Subsequently, a global aggregation process is then performed to compute the query's result without rescanning the table. Queries featuring a minimum equality condition are similarly processed in accordance with the disclosed embodiments.
