摘要： An overloaded routines resolving method of analyzing an invocation for the group of overloaded routines to determine the routine to be called, the method including: the routine group sorting step of sorting the group of routines on the basis of the predetermined precedence; the reference utilization pruning step of determining the routine which has the highest precedence of a data type of an argument from among the routines which can be called for the types in the definition of the arguments of the invocation from the sorted routines and of deleting any of the routines each of which has the lower precedence than that of the routine thus determined from the candidates; and the sort order characteristic pruning step of comparing the data types of the arguments among the routines which still remain after having executed the reference utilization pruning step to delete any of the routines each of which has no possibility of being called from the candidates. From the foregoing, the necessary minimum candidate can be selected efficiently in the overloaded routines resolution which is carried out when analyzing the query for the database.

摘要： A method and a system of database divisional management for use with a parallel database system comprising an FES (front end server), BES's (back end servers), an IOS (I/O server) and disk units. The numbers of processors assigned to the FES, BES's and IOS, the number of disk units, and the number of partitions of the disk units are determined in accordance with the load pattern in question. Illustratively, there may be established a configuration of one FES, four BES's, one IOS and eight disk units. The number of BES's is varied from one to four depending on the fluctuation in load, so that a scalable system configuration is implemented. When the number of BES's is increased or decreased, only the management information thereabout is transferred between nodes and not the data, whereby the desired degree of parallelism is obtained for high-speed query processing.

摘要： A database management system for executing database operations in parallel by a plurality of nodes and a query processing method are described. The database management system contains a decision management node for deciding a distribution node for retrieving information so as to analyze a query received from an application program, generate a processing procedure for processing the query, and execute the process, and a join node for sorting, merging, and joining the information retrieved by the distribution node. When the query process is executed, the distribution node decided by the decision management node retrieves the information to be processed and the join node decided by the decision management node also obtains the result for the query from the retrieved information. The query result is outputted from an output node and transferred to the application program.

摘要： A request accepting server accepts a processing request of data of a predetermined type, analyzes the request, and allocates a process corresponding to the request to either one of the request accepting server and at least one database processing server. A handle is a control block to manage a storage area of data as a processing target and has a server in which the processing target data has been stored and information regarding its storing position. When the processing target data corresponding to the processing request is processed in accordance with the processing request, the request accepting server executes a process according to the processing request by using a handle regarding the processing target data. When an entity of the processing target data is necessary, the entity of the processing target data is obtained on the basis of the handle and is processed.

摘要： In a data base processing method including a central processing unit for analyzing a plurality of queries made from a plurality of users so as to determine an internal processing procedure with respect to a data base, and for performing the internal processing procedure; a secondary storage for storing data capable of being shared by each user; and, an input/output controlling processing unit including at least one cache storage, for controlling a transfer of a plurality of records which are required for input/output processing operations between the central processing unit and secondary storage. The data base processing method is featured in that a decision is made whether or not a prefetching operation is carried out at a start of an input/output processing operation by judging the internal processing procedure which has been formed by the query; a retrieval range into which a record to be fetched has been stored is formed when the prefetching operation is performed; and, a prefetching record number is determined as an input/output processing demand unit, taking account of an access characteristic of the internal processing procedure and also a system characteristic containing a size of the cache storage, a performance, of the central processing unit, and a traffic of the input/output processing unit.

摘要： With respect to input/output requests; a microprogram controls collection of data according to the data format; data accessing divides the requests for every recording medium and performs asynchronous processing; an on-line process is carried out in view of the processing priority order of the requests; parallel accessing sets requests for each medium; buffer control assures a block buffer and a page address list before receiving requests; data accessing sets a list of CCHHR codes in response to a continuous characteristic of the stored state in the recording medium; and mode deciding judges the two data transfer modes, a page search mode and a data search mode, in response to the requests.

摘要： In order to perform merging sorting which can flexibly cope with the variation of a data length, data is divided every predetermined number of bits (m bits), a plurality of processors each of which process the m-bit data are connected, and the alteration of the data length can be coped with by changing the number of the connected processors. On this occasion, in order to permit reduction in the quantity of information items which are exchanged among the respective processors, the merging sorting is so carried out that the processor processing certain m bits receives input information from only the processor processing immediately upper m bits and delivers output information to only the processor processing immediately lower m bits.

摘要： A database processing method for defining and operating data of file reference type which references a file. A column data insert request for specifying position information indicative of a storage location of a file and watch information for watching the file is received from a database client. A request for watching a file indicated by the position information is issued in accordance with the watch information. The position information and the watch information are stored in a database. The foregoing operations permit data in an external file placed outside a database to be treated as data equivalent to ordinary column data stored in the database to improve the integrity of the database.
