摘要： PROBLEM TO BE SOLVED: To improve system performance by preventing the overlap or concentration of processing for possessing input information by possessing the input information by executing an integrated module for input information possession on a request reception server according to recognition. SOLUTION: A request from an application program 101 is received from a request reception server 105. An inquiry processing control part 109 analyzes a user inquiry 104 while using an inquiry analytic part 110. As a result of this analysis, the execution procedure code pattern selected result is possessed. The inquiry processing control part 109 prepares an execution procedure code 111 while using an execution procedure code preparing part 114 based on the possessed execution procedure code pattern selected result. The inquiry processing control part 109 instructs an execution server 106 to perform processing matched with the request of user while using an execution instructing part 115 based on the possessed execution procedure code 111. The execution server 106 executes processing matched with the request and directly transmits the executed result through a communication path 108 to an executed result holding part 118.

摘要： PURPOSE:To attain a fuzzy DB inquiry processing system with high performance and effective using procedure by forming a result adding fuzzy grades corresponding to respective fuzzy items. CONSTITUTION:A fuzzy inquiry executing/evaluating part 24 generates a command string formed by a fuzzy inquiry execution code forming part 212 to a DB control system or a file system in accordance with the specified processing order and acquires the processed result. A membership function for quantitatively measuring the equivocation of the data value of a fuzzy item included in the processed result is applied to the data value, the fuzzy grade expressing the equivocation of the data value is calculated, an inquiry condition based upon equivocation expression is evaluated and the fuzzy grade corresponding to each fuzzy item is added to the result obtained by the evaluation to form the added result. Consequently, the performance and using procedure of the fuzzy inquiry processing system are improved and the attaining method of the whole system is made clear.

摘要： PURPOSE:To improve the performance of the whole system by recursively applying processing relating to the reference information of a method also to reference information stored in a reference method and loading the 1st to n-th order evaluation objects from an object data base to an object area. CONSTITUTION:An object control part 14 loads a requested object from the object data base 16 onto the object area 17 when an object request is generated from a message processing part 12, checks the primary reference instance variable by the reference information of a method specified by a selector and loads the object stored in the instance variable by the request object onto the object area 17. The control part 14 recursively evaluates the reference information of the executed method and controls the loading of individual instance objects constituting a composite object having the requested object at its top. Consequently, the object having the high probability of use out of all the objects constituting the composite object can be set up in the object area and the performance of the whole system can be improved.

摘要： PURPOSE:To determine uniquely a succeeding stand-by online program and to facilitate an operation by preparing two stand-by online programs simultaneously for one online program. CONSTITUTION:A management program MPGM 1131 starts a standby online program SBPGM 1132 equal to an SBPGM 1122, and a CPU 113 gets an unique sequential number in a system with respect to SBPGM. The MGPGM 1131 requests the sequential number of SBPGM to MPGMs 1111 and 1121 through communication lines 132 and 133. The value obtained by adding one to a sequential number 11221 from the MNGPGM 1121 is defined as a sequential number 11321 of the CPU 113. Thereafter, the start completion of the SBPGM 1132 is reported to CPUs 111 and 112. As the result, the SBPGM 1122 is moved from the CPU 112 to the CPU 113.

摘要： PROBLEM TO BE SOLVED: To enable modifications of attributes, relations, and procedures to an object independently of schema definition information in an object-oriented database. SOLUTION: Objects and component objects which hold the modification information of the objects are stored in a database 107 which is managed by a component object management part 102 and an object management part 103. The definition information of objects and component objects which hold modification information of the definition information are stored in a dictionary 108 which is managed by a dictionary management part 104. In response to users' requests, a view management part 101 manages views for dynamically generating the definition information of objects after definition modification and the objects through management parts 102, 103 and 104. An update history management part 105 extracts the modification histories of objects from component objects and outputs them to a journal 106. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PURPOSE:To improve convenience by interruption the retrieval processing according to the user's instruction for retrieval request which takes long retrieval processing and deciding the right or wrong of continuation based on the user's judgement. CONSTITUTION:A user sets the right or wrong of interruption function execution and a parameter for allowable retrieval processing time (T) before calling for the retrieval request to a data base management system 50 by means of a terminal 10. He monitors retrieval processing time during retrieval processing and interrupts the processing in the case the retrieval processing time exceeds the allowable retrieval processing time. After the interruption, the data base management system 50 asks the continuation of the interrupted processing, and decides the continuation or invalidity of the interrupted processing based on the instruction of the user by receiving the right of wrong of the continuation of the interrupted processing from a user. Thus, the convenience can be improved.

摘要： PURPOSE:To efficiently execute the re-settling processing of succession by considering the priority order of a super-class according to defined contents at a stage in the course of application development. CONSTITUTION:A storage means to hold succession settled state information consisting of status information showing whether the succession of that class was perfectly settled or not and status fixed time showing time at which a status was fixed is provided for every class unit. Then, in the case the succession settling processing of some class is executed, the objective super-class of the succession settling processing is selected successively from the super-class of the higher priority order, and the status fixed time of the class and the status fixed time of the objective super-class are compared with each other, and when the status fixed time of the class is before the status fixed time of the objective super-class, the succession settling processing is recursively executed about the objective super-class, and after the succession settling processing of the objective super-class, the definition contents of the super class is succeeded by that class. Thus, the settlement of the succession can be advanced according to the progress of the application development.
