Abstract: A DBMS manages a database including a structured data group capable of communicating with a plurality of execution nodes that manage an unstructured data group and execute parallel distributed processing. Each of the plurality of execution nodes is capable of creating data to be processed based on at least one structured data of the structured data group managed by the DBMS and at least one unstructured data of the unstructured data group managed by the plurality of execution nodes, and performing processing using the data to be processed. Based on control information (information about controlling the provision of two or more structured data designated in a reference request sent to the DBMS), the two or more structured data are acquired by the DBMS from the database, and provided from the DBMS to two or more execution nodes among the plurality of execution nodes.

Abstract: A data management method employing the results of an analysis of data stored in a storage unit of a computer provided with a processor and a storage unit, wherein the computer generates an analysis data set by selecting data stored in the storage unit, subjects the analysis data set to prescribed data mining, extracts a model from the analysis data set, converts the model into a relational table, and associates the relational table with a dimension table and a history table that have been stored in advance in the storage unit.

Abstract: A join query execution method and device include a processor and storage medium. An external data source connected to a data management system by a table function is searched, regarding and joining processing against a join query regarding a search result of the table function and a table managed by the data management system, the joining processing is executed on the search result by a first joining method; a join query execution device determines whether the first joining method is appropriate, by using information acquired by search processing on the external data source; and when it is determined that the first joining method is not appropriate, the join query execution device recognizes a speed of a second joining method to be higher than that of the first joining method and switches the joining method for the joining processing to the second joining method.

Abstract: Buffer management unit selects the input and output buffer to be set as a replacement target referring to the input and output buffers in order and calculates the number of times of replacement execution for the input and output buffer and reference speed for referring to the input and output buffers in order. At execution of pre-write processing, the pre-write management unit selects, according to position information of the input and output buffer subjected to the last pre-write processing, position information, and the number of times of replacement execution, the input and output buffer to be set as a target of the present pre-write processing. When updated data is present in the input and output buffer, the pre-write management unit writes the data in the secondary storage device and executes the next pre-write processing according to the reference speed.

Abstract: An exposure apparatus comprises an exposure device configured to perform an exposure process for a substrate, and a controller configured to control an operation of the exposure device in accordance with control software and perform an update process for the control software. The controller is configured to queue an exposure job corresponding to the exposure process and an update job corresponding to the update process; and cause the exposure device to perform an exposure process corresponding to the queued exposure job if the queued exposure job is output, and perform an update process corresponding to the queued update job if the queued update job is output.

Abstract: In reference, update, and insertion processing, the lock of an un-transferred object is released, and then the lock of a transferred object is set when the pointer is traced for transfer between objects to thereby improve the parallel execution capability of the reference, update, and insertion. At that time, the IS-mode (in the case of reference processing) or the IX-mode (in the case of update and insertion processing) is set at the starting of the processing, and the lock is released at the time of completion of the processing. Furthermore, in deletion processing, after the pointer to a deletion target is separated or replaced and all the processing that acquires the lock of an object group has been completed, the region of the deletion target object is released.

Abstract: A method for creating an index for searching a structured document having a document data-structure stored, in a computer. The method to be performed in the computer for creating an index includes the steps of: analyzing a structured document to extract a document data-structure in the structured document; normalizing the extracted document data-structure to create a logical structure index composed of a plurality of elements having a hierarchical structure; extracting an appearance number of each element in the created logical structure index; and extracting elements for creating the index, based on the logical structure index, by comparing the extracted element appearance number and a first predetermined threshold.

Abstract: In a transaction parallel control method of a DBMS, if a priority of a transaction process accepted from an application is higher than a transaction process of an application being executed or suspended, a conflict is judged between database resources used by the both processes and a transaction process to be suspended or terminated is determined based on types and values of the database resources acquired by the respective processes. After the determined transaction process is suspended or terminated, the transaction process of the application is executed by acquiring a value corresponding to the type of the database resource included in the database resource acquisition schedule information accepted from the application and, after the completion, the suspended transaction is restarted.

Abstract: A database system for storing table data as divided in a plurality of storages has a processing request acceptance section and an execution section which, at the time of rebalancing already stored data in response to addition of a storage, can execute inquiry operations concurrently. The system determines data to be moved from existing storages to the additional storage. When search, update and delete processing requests are issued during execution of the rebalance operation of copying the data to the additional storage and deleting the original data, both the DBMS acceptance section and DBMS executor section execute the operation corresponding to the requests. When an insert processing request is issued, the system determines a data insert destination on the basis of contents of a step of dividing the data from the existing storages to the additional storage.

Abstract: A method of allocating storage areas, intended to reserve the storage areas formed on a storage device for storing data, this method including the steps of: registering beforehand as a storage configuration information table 105, information on multiple storage areas to be managed and on the position where the storage device is installed; registering information on the purposes of use and positions of the storage areas beforehand as a position management table 107; acquiring position information from the position management table 107 in accordance with an allocation request for a storage area associated with the purpose of use; selecting an unallocated storage area from the storage configuration information table 105 with reference to the position information; and sending information on a selected area to a client from which the allocation request was issued.

Abstract: A database access management unit manages accesses to databases managed by a plurality of data processing servers each provided for each data kind. A request analysis unit analyzes a request from an application containing a process request for each data kind. A process server selection unit selects the data processing server for executing a data process in accordance with the data kind. A data process request unit requests the data processing server to execute the data process. A process result edition unit edits the process result by the data processing server.
