摘要： PROBLEM TO BE SOLVED: To define schemer information of input electronic data and output electronic data, to separate and manage the local structure of electronic data and its correspondence relation, and to enable the definition data to be reused. SOLUTION: A user who defines an electronic data conversion rule inputs a data model for input electronic data or output electronic data on a screen and a data model information definition screen program 121 defines data model definition information 141; and the user inputs data models for the input electronic data and output electronic data on the screen and inputs the relation definition between the pieces of data on the screen and a mapping information definition screen program 125 defines mapping definition information 143 on a conversion rule between data items of the data models and the correspondence relation by using those inputs and data model definition information 141. When schemer information of the electronic data is defined, a schemer information definition screen program 123 imports the data models from the data model definition information 141 to generate format definition information 137 and schemer definition information 139.

摘要： PROBLEM TO BE SOLVED: To provide an object managing method which can efficiently process object operation by a client application without communicating with a server while guaranteeing object discrimination in an object-oriented data base system constituted in a client-server type. SOLUTION: An object management part 107 of a database management(DBMS) client 106 allocates a temporary object identifier(OID), based upon a serial number (generation serial number 113) of object generation order, to a generated object 108. To an update message 115 that the database management(DBMS) client 106 generates, OID conversion information showing the position of the temporary OID in the message is added. A database management(DMMS) server 103 stores the generated object so that access efficiency of a data store 104 is improved, and converts the temporary OID into a format OID which is unique in the system according to the OID conversion information.

摘要： PURPOSE:To attain the flexible operation of an object by substituting information held in each variable when a pseudo variable is referred to in a restricting condition. CONSTITUTION:Class definition is executed by a class definition part 303 and analyzed by a class compiler 304 and the analyzed result is stored in an object control part 305. Operation such as the addition, updation and deletion of data is executed by outputting a message to an object included in a system through a message processing part 302. When the pseudo variable appears in a method code, the entry of a variable name coincident with the variable name of the pseudo variable concerned is searched from a pseudo variable list and the pseudo variable concerned is substituted by the object held in the entry. The restricting condition is executed after processing all messages for an overall interface. The message held in the pseudo variable is sent to an obtained version.

摘要： PURPOSE:To improve the deletion processing performance by providing each object with a shared counter where the number of the other objects having hierarchical relations to this object is stored. CONSTITUTION:When an object is generated, a data base management system 50 initializes the shared counter of this object to 0. When deletion of a single object is designated, the shared counter of this object is checked, and deletion of this object is suppressed when its value is one or more, but this object is deleted from a data base 40 when its value is 0. In the case of a deletion request of plural objects, deletion of objects except apexes is executed when values of shared counters of these objects are one, but deletion of objects is suppressed when they are two or more.

摘要： PURPOSE:To attain a data retrieving method having high operability to the data of a complicated structure by acquiring a path of a class equivalent to the relation of the type given from the class relative information and deciding an operating subject instance accordant with the path with the given relative instance defined as a starting point. CONSTITUTION:A data base control system 50 produces the relative substance information set between a relative matrix and an instance from the class relative information showing the presence or absence of the relation obtained between classes for each type of relation. Based on the relative substance information, the relative substance is traced with a given relative instance defined as a starting point. Thus an operating subject instance is decided. Thus it is possible to obtain a data retrieving method having high operability to the data of a complicated structure.

摘要： PURPOSE:To reduce the load at execution and to increase the message processing speed by using both early and late binding processes and switching them with each other based on the situation. CONSTITUTION:Both early and late binding processes are applied to each message in its compiling state. In the early binding process, the data type check, etc., are carried out in a compiling state. The time when the class of an object which produced a message is compiled is added to each message, and the time when the class including a method is compiled is added to each method. When a message is transmitted, the compiling time included in the message is compared with the compiling time of the class including the corresponding method. If the message compiling time is later than the class compiling time, an immediately following method is carried out in an early binding process having a light executing time load. Otherwise the method is carried out after a message is dynamically analyzed and the message type is checked. As a result, the load can be reduced at execution and the message processing speed is increased.

摘要： PURPOSE:To attain an automatic data processing method by holding the related control information for each record type and controlling the process which is carried out to other records (related records) related to the record (trigger record) that received a process request based on the related control information. CONSTITUTION:For decision of the necessity/unnecessity for a process to be given to the related record of a trigger record, the relation held directly by the type of the trigger record is first decided. Then the necessity/unnecessity is decided for the process given to the related record based on the directional attribute and the process attribute. When the related record is processed by decision, the same decision is applied to the relation held by the type of the related record. In such a way, all records related directly or indirectly to the trigger record are decided based on the related control information. Thus the processes given to the related records can be automatically controlled.

摘要： PURPOSE:To reduce the user load for production of an application program by acquiring the information on the parameter necessary for execution of a dynamic data base operation when the analysis is requested. CONSTITUTION:An application program 20 delivers the information on the parameter necessary for execution of a data base operation language to the receiver side together with a data base operation language sentence when a dynamic analysis request is received for the language sentence. A data base control system 10 analyzes the received language sentence and sends the data type of a variable parameter, the field name of the record to be retrieved, and the data type back to the designated receiver side. Thus the program 20 can set the parameter information based on the information on the parameter after the analysis and therefore is not required to analyze the data base operation language sentence by itself.

摘要： PROBLEM TO BE SOLVED: To make a query similarly to ordinary data types even when a new data type is added by generating a query statement by using inputted information, issuing the generated query statement to a data base management system, and obtaining its query result. SOLUTION: When a data type to be queried is an additionally defined data type, a query execution control part 201 retrieves a query component 221 supporting the query for data of a data type from query component information 230 and actuates it, and displays a screen for inputting information needed to query the data of the data type to input the information from a query input part 202. The query input part 202 provides an interface for interactive querying. A query result output part 203 outputs data obtained as a query result according to the output specification of the query result inputted to the query input part 202.
