    Abstract: [Object] In a business application system, it is important to shorten a time of halt of a service due to a failure in a server, a network or the like. As current failure addressing is generally a method by failure-detection and take-over. As the failure-detection requires at least ten seconds to a few minuets, a service halt time is more than that, which causes a significant problem. [Solution] The present invention proposes a system for resending a process to a backup server farm from a client without waiting for the failure-detection, if no reply is received for a certain time. The transaction processing mechanism of the present invention has a transaction start processing mechanism in which an exclusive control using a processing authority Token and data consistency are combined, and a commit processing mechanism in which determination on whether a commit is available or not based on a distributed agreement and replication of updated data. With the mechanisms, a system for shortening a service halt time when a failure occurs to a time as such it appears to a client that the service does not stop is provided.

    Abstract: [PROBLEMS] In a business system, it is important to reduce the time of a temporary service interrupt due to failure of a server or a network. The cur rent failure countermeasure is generally performed by a failure detection an d a handover. However, the failure detection requires at least 10 seconds to several minutes and the service interrupt time is longer than this, which c auses a significant problem. [MEANS FOR SOLVING PROBLEMS] Suggested is a sys tem for retransmitting process to a backup server firm from a client if no r esponse is received for a certain time without waiting for the failure detec tion. A transaction process mechanism includes a transaction start process m echanism combining an exclusive control using the process authority Token an d data matching and a commit process mechanism combining the commit enabled/ disabled judgment based on the distributed agreement and the update data rep lication. This mechanism realized a system capable of reducing the service s top time upon failure occurrence to a time of such an order that the service does not stop when viewed from the client.

    Abstract: PROBLEM TO BE SOLVED: To provide a method, program, and system for converting graph data to a data structure that enables manipulations in various applications to be reflected in the original graph data.SOLUTION: The method uses at least one graph matching pattern to convert at least a part of graph data including nodes and edges to a data structure as an image of a homomorphism thereof. A pattern is provided which includes one and only representative node variable having a first constraint that at most one node in the graph data matches the representative node variable and that the node is prohibited from matching a node variable in another pattern. The method includes the steps of: performing matching between the graph data and the pattern to obtain a matching result that does not violate constraints including the first constraint; and generating a data structure corresponding to the matching result that does not violate the constraints.

    Abstract: PROBLEM TO BE SOLVED: To reduce access frequency to an existing tool in converting data into RDF through the access to the existing tool.SOLUTION: A set of IDs for data of an existing tool is embodied as a parameter; a bulk access template is prepared that acquires a plurality of data pieces one time, or a few times at most; and access to the existing tool is provided through the bulk access template. The bulk access template is prepared for each type of data to be acquired. Next, the template is instantiated based on a requested URI, and entries that correspond to an operating table are filled in by executing the instantiated template. When an RDF expression is requested for the URI of the template that is the same as one already accessed, the entries are already in the operating table, so that the RDF expression can be generated without generating access to the existing tool.

    Abstract translation: 要解决的问题:减少通过访问现有工具将数据转换为RDF的现有工具的访问频率。解决方案:现有工具的数据的一组ID被体现为参数; 准备一个批次访问模板,其中获取多个数据片段最多一次或几次; 并通过批量访问模板提供对现有工具的访问。 批量访问模板是为每种待获取的数据准备的。 接下来,基于请求的URI来实例化模板,并且通过执行实例化的模板来填充与操作表相对应的条目。 当为与已访问的模板相同的模板的URI请求RDF表达式时,这些条目已经在操作表中,因此可以生成RDF表达式而不生成对现有工具的访问。
