Problems solved by technology
[0009] However, in conventional data processing systems, since data is centrally managed, a system administrator who manages the entire data processing system also performs data management, and thus there is a problem related to data confidentiality
[0010] In addition, centralized management of data increases the amount of data to be managed, which involves an increase in operating costs such as costs for equipment enhancements.
[0011] In addition, although the invention disclosed in Patent Document 1 that data is managed by the original data owner, the interdependence between applications and data is still high, and it is necessary to develop applications suitable for each enterprise to manage data, and Build a data processing system, which incurs an increase in development costs

Embodiment Construction
[0047] Hereinafter, the present invention will be described in detail based on the drawings showing the embodiments of the present invention.
[0048] Fig. 1 is a block diagram showing the configuration of the data processing system of the present invention.
[0049] The data processing system of the present invention is a system mainly used in a database system, and has: a processing device 10, which is recorded with application programs such as a processing program for processing data; recording medium REC such as CD-ROM and floppy disk; and command means 30 for sending commands to the processing means 10. The processing device 10, the access device 20, and the command device 30 communicate through a communication network NW such as a LAN.
[0050] In addition, in the data processing system shown in FIG. 1 , although a communication network NW constituted by a ring topology is shown, and a configuration in which each processing device 10, access device 20, and command devic...

To provide a data processing system, a processing apparatus and a computer program for dispersing the loads imposed on units constituting the system in a data base system to enhance a security of the data, a processing unit for recording an applied program, an access unit for accessing a recording medium REC recording data, and a command unit for sending a command for processing the data are independent of each other, if the recording medium REC may be accessed from the access unit, information such as position information for indicating the recording position of the data is sent to the processing unit, a command including a program identifying information for identifying the applied program is sent from the command unit to the processing unit, the data recorded in the recording position indicated by the position information are extracted on the basis of the command received in the processing unit and are processed by an applied program identified by a program identifying information.
Description
technical field [0001] The present invention relates to a data processing system for processing data by executing a command-based program, a processing device used by the system and a computer program for implementing the device, in particular to a data processing system, a processing device and a computer program for improving the confidentiality of data Computer program. Background technique [0002] Patent Document 1: JP-A-2002-207627 [0003] As large-scale data processing systems for processing data by executing application programs that act on basic programs using computers, there are stand-alone systems, server-client systems, and host-guest systems. [0004] A stand-alone system is one that uses a single computer for processing applications and data. [0005] The server-client system is a system composed of multiple computers in the relationship between a server computer that provides services and a client computer that utilizes services. The data itself is sometim...
