An ennoversion management system is adapted to a data processing system executes a desired process by naming as objects single processing units and/or composite processing units which are combinations of the single processing units and combining the objects. In the ennoversion management system, a real world is understood as an object model, the real world is made to correspond to an extension and a connotation, the connotation is placed in an information concealed region, and ID information which specifies the connotation in correspondence with the extension is formed. The real world is described by a dynamic world and a static world forming a world of the objects in correspondence with the extension, a system mechanism is given as a static model with respect to the static world using classes and/or composite classes, and a session corresponding to a motion of the dynamic model is given as a dynamic model with respect to the dynamic world using instances of the composite classes and/or the classes. Cause and effect relationship generated from the dynamic model is given into the static model as information. The classes and/or composite classes are formed by combing a plurality of existing and/or newly generated methods, and the instances are formed in correspondence with the classes and/or the composite classes. The existing and/or newly generated methods, the formed classes and/or composite classes, and the session corresponding to the motion of the dynamic model are stored as composite objects in the information concealed region corresponding to the connotation as a functional model. In correspondence with the identification information, the objects and/or composite objects stored in the connotation as a functional model are reusably formed. An ennoversion management with respect to the classes, the composite classes, the instances and the sessions is carried out.

Ennoversion management system for data processing system

An object base data processing apparatus executes a desired process by naming, as objects, single processing units and/or composite processing units which include single processing units and combines the objects. A parts attribute file stores the object parts using entity data forming the objects and meta data describing a nature of the objects, methods and/or classes for realizing individual processes, which are information groups in a procedural world, stored as objects. An object management unit communicates with the object parts in the parts attribute file to execute the desired process. A class schema describes a method name for at least one method entered in the class by combining at least one of the methods into the class. An instance schema generates an instance linked to a method specified by the class schema. The object parts correspond to the composite processing unit linking the methods described in the class schema and contents of the instance schema. The desired process is given by a static model, specifying an existence of class groups and/or the method groups and mutual relationships of the class groups and/or the method groups; and a dynamic model specifying an existence of instance groups and time sequential relationships of the instance groups. Progress of a process of the instance in the dynamic model is executed by collation with cause and effect relationships among the classes in the static model.

Object base data processing apparatus

A data processing system for executing a process. Classes and composite classes are formed by combining methods. Instances are formed and correspond to the classes and composite classes. The real world is analyzed as an object model which includes a static world, a dynamic world and a cause and effect relationship. The object model has a corresponding extension and a corresponding connotation. The connotation is in an information concealed region, and identification information identifies the extension and connotation. A system mechanism is created with respect to the static world using the classes and composite classes, where the system mechanism is a static model for the static world. The instances are used to form a session corresponding to motion with respect to the dynamic world, where the session is a dynamic model for the dynamic world. The cause and effect relationship of the object model is generated from the dynamic model into the static model. A functional model is formed in the connotation, and includes composite objects formed from the methods, the classes, the composite classes and the session. A minimum number of methods, classes, and composite classes required to form the composite objects of the functional model are stored in the connotation. The identification information is used to assign object identifications to composite objects of the functional model, to identify composite objects of the functional model. A process is then executed by using the object identifications to identify composite objects of the function model.

Data processing system which executes composite objects by combining

An object-oriented data processing system includes a link setting unit for setting a link between a plurality of composite objects to provide a structure to a static model and a dynamic model such that the link includes: a strong link that causes an automatic propagation of an operation applied to a composite object, to another composite object connected by the strong link; and a weak link wherein propagation of an operation applied to a composite object occurs to another composite object connected by the weak link, conditionally.

Distributed processing in a system of computers at terminals connected

The system provides a data storage system program 18 between a user and a physical memory device 14 which stores file records 20. The data storage system 18 stores records as linked record segments 40/51 that can be randomly located within the memory storage device 14. The segments 40/51 are linked by a next segment address found in a next segment address field 50/56 of a record segment 40/51. When a record needs to be expanded and the current record segment 1000 is not large enough to accommodate the expansion, another record segment 1082 is allocated and used. If variable length record segments 40 are used, only a single record extension is required. However, if fixed length record segments 50 are used, the system allocates sufficient fixed length record segments to store the additional data. When records shrink in size or are deleted, the vacant space becomes available for reuse and the system attempts to remove the vacant space by combining record segments and storing a single segment in available vacant space.

Dynamic data storage system allowing variable size records and fields by

Network control system

The present invention is a system that converts a vertical file (28) of time series data records from multiple terminals (10-14) and stored by time into a horizontal file (52) where records are organized by terminal (10-14). The user can then access the desired terminal information rapidly in the horizontal file (52) rather than having to perform an inefficient sequential search of the vertical file (28). After the terminal data is horizontally stored, the data is used to create display or print-out windows of the terminal data for many locations. Each window includes the data from a single terminal (10-14). For example, each window could include a graph of rain data for a location. The system also creates a cross reference table (76) of the addresses of the data used to create each window. When the display arrangement is altered, the data in the horizontal file (52/74) is reorganized to match the display order while only the physical addresses of the data for each terminal are changed in a new cross reference table (80).

Sampled data storage and editing system for the time series data being
