Abstract

A method and an apparatus for confirming matching of data in a distributed processing system aiming easy maintenance of the matching of the data and efficient parallel design work in a distributed processing system. In the distributed processing system having a server including a database and plural clients utilizing data in the database, said server and clients are connected to each other. The server stores information of destinations to which data in the database has been distributed and receives information of an editorial history of the data from a client that is a destination of the distributed data to store the editorial history information at the destination client on the side of the server. After that, matching of the data is confirmed on the side of another client on the basis of the distributed data'"'"'s destination information or the editorial history information stored in the server.

Claims

1. An apparatus for confirming matching of data in a distributed processing system in which a server having a database and plural clients using data in said database in said server being connected to each other through a network, comprising:

said server comprising;

said database;

a distributed data'"'"'s destination storing unit for storing therein distributed data'"'"'s destination information of data in said database;

an editorial history storing unit for storing therein editorial history information of the data at a distributed data'"'"'s destination client; and

a data communication function unit for transmitting and receiving the data to and from said clients; and

said client comprising;

a data communication function unit for transmitting and receiving data to and from one of said server or another client;

a sub-database for storing the data in said database in said server;

a data edit function unit for editing the data;

an editorial history storing unit for storing editorial history information depending on a result of edition performed in said data edit function unit;

a display unit;

a distributed data'"'"'s destination information demanding unit for demanding the distributed data'"'"'s destination information stored in said server from said distributed data'"'"'s destination storing unit of said server through said data communication function unit;

an editorial history information demanding unit for demanding the editorial history information from said editorial history storing unit of one of a distributed data'"'"'s destination client and said server on the basis of said distributed data'"'"'s destination information obtained by said distributed data'"'"'s destination information demanding unit; and

an editorial history information display control unit for displaying the editorial history information obtained by said editorial history information demanding unit on said display unit.

2. An apparatus for confirming matching of data in a distributed processing system according to claim 1, wherein each of said client further comprising a data altering unit for altering the data of said client on the basis of the editorial history information of said distributed data'"'"'s destination client sent to said client.

3. An apparatus for confirming matching of data in a distributed processing system in which a server having a database and plural clients using data in said database in said server being connected to each other through a network, comprising:

said server comprising;

said database;

a distributed data'"'"'s destination storing unit for storing therein distributed data'"'"'s destination information of data in said database;

an editorial history storing unit for storing therein editorial history information of the data at a distributed data'"'"'s destination client; and

a data communication function unit for transmitting and receiving the data to and from said clients;

each of said client comprising;

a data communication function unit for transmitting and receiving data to and from one of said server and another client;

a sub-database for storing the data in said database in said server as image information;

a data edit function unit for editing the data;

an editorial history storing unit for storing the editorial history information depending on a result of edition performed in said data edit function unit;

a display unit;

a distributed data'"'"'s destination information demanding unit for demanding the distributed data'"'"'s destination information stored in said server from said distributed data'"'"'s destination storing unit of said server through said data communication function unit;

an image information demanding unit for demanding the image information representing a final state of an editorial history of the data at said distributed data'"'"'s destination client as an image from said sub-database of said distributed data'"'"'s destination client on the basis of the distributed data'"'"'s destination information obtained by said distributed data'"'"'s destination information demanding unit; and

an image information display control unit for displaying the image information obtained by said image information demanding unit on said display unit.

4. An apparatus for confirming matching of data in a distributed processing system according to claim 3, wherein each of said clients comprising a data altering unit for altering the data of said client on the basis of the image information of said distributed data'"'"'s destination client sent to said client.
