Abstract

A data delivery system which delivers created data to all the parties that need it. Documents such as engineering drawings are stored as bulk data files in a bulk data database. Metadata files containing attribute information of bulk data are stored in a metadata database. When the date and time of a data distribution session is given to a date/time setting unit, an attribute identification unit makes access to a relevant metadata file to identify the attributes of the bulk data to be transmitted. Based on this result, a destination determination unit determines the destinations of each bulk data file. A format identification unit then identifies which data formats the receiving stations can handle. If necessary, the data format is changed by a format converter, so as to meet the requirements of each destination. Summary data briefly describes what kinds of bulk data files are to be distributed. A summary data transmitter compiles such summary data and sends it to the receiving stations. Each receiving station now returns a downloading request, and in response to this, a transmitter sends out the requested bulk data files, which meets the destination'"'"'s format guideline. A receiver in the receiving station accepts those bulk data files and a reproduction unit restores the received data to its original form.

Claims

1. A data delivery system for delivering data stored in a sending station to at least one receiving station, comprising:

distribution tables, disposed in the sending station, each defining parameters regarding where and how to deliver engineering documents of a particular product category, the parameters including destinations of each different type of documents and data formats supported in each of the destinations;

attribute identification means, disposed in the sending station, for identifying attributes of data to be distributed, the attributes including document types;

destination determination means, disposed in the sending station, for determining destinations of the data, according to the document type identified by said attribute identification means, by consulting one of said distribution tables relevant to a specified product category;

transmission means, disposed in the sending station, for sending the data to the destinations determined by said destination determination means;

reception means, disposed in each receiving station, for receiving the data sent from said transmission means;

reproduction means, disposed in each receiving station, for restoring the data received by said reception means to original form thereof;

data conversion means, disposed in the sending station, for converting the data into image data or plotter data;

distribution information embedding means for adding distribution-related information pertaining to the data distribution to the image data or plotter data produced by said data conversion means, and

wherein said transmission means sends the data converted by said data conversion means.

2. The data delivery system according to claim 1, further comprising:

format identification means, disposed in the sending station, for identifying which data format each receiving station supports; and

format conversion means, disposed in the sending station, for performing data format conversion to make the data compatible with the data format identified by said format identification means.

3. The data delivery system according to claim 1, further comprising parameter storage means, disposed in the sending station, for storing parameters that are necessary for said format conversion means to perform the data format conversion.

4. The data delivery system according to claim 1, further comprising summary data transmission means, disposed in the sending station, for sending summary data that briefly describes the data to be distributed,

wherein the receiving station requests a particular part of the data as a result of reference to the summary data received from said summary data transmission means, and said transmission means sends the particular part of the data accordingly.

5. The data delivery system according to claim 1, further comprising authentication means, disposed in each receiving station, for verifying authenticity of a receiving user,

wherein said transmission means sends the data to the receiving station when said authentication means has successfully verified the authenticity of the receiving user.

6. The data delivery system according to claim 1, further comprising date setting means, disposed in the sending station, for specifying a date and time of sending the data,

wherein said transmission means retrieves and sends the data when the specified date and time is reached.

7. The data delivery system according to claim 1, further comprising:

a firewall interposed between the sending station and the receiving station; and

a distribution server interposed between said firewall and the receiving station,

wherein, in the case that the system delivers the data to a plurality of receiving stations, a single instance of the data is passed from said transmission means to said distribution server through said firewall, and

wherein said distribution server produces as many copies of the data as required for distribution to the plurality of receiving stations.

8. A sending station which sends data recorded in an internal or external storage unit to at least one receiving station, comprising:

distribution tables, each defining parameters regarding where and how to deliver engineering documents of a particular product category, the parameters including destinations of each different type of documents and data formats supported in each of the destinations;

attribute identification means for identifying attributes of data to be distributed, the attributes including document types;

destination determination means for determining destinations of the data according to the attributes identified by said attribute identification means; and

transmission means for sending the data to the destinations determined by said destination determination means;

data conversion means, disposed in the sending station, for converting the data into image data or plotter data;

distribution information embedding means for adding distribution-related information pertaining to the data distribution to the image data or plotter data produced by said data conversion means, and

wherein said transmission means sends the data converted by said data conversion means.

9. A computer-readable medium containing a program which delivers data stored in a sending station to at least one receiving station, the computer program being designed to run on a computer in order to cause the computer to execute operations, comprising:

providing distribution tables, each defining parameters regarding where and how to deliver engineering documents of a particular product category, the parameters including destinations of each different type of documents and data formats supported in each of the destinations;

identifying attributes of data to be distributed, the attributes including document types;

determining destinations of the data according to the attributes identified; and

sending the data to the destinations determined;

wherein the data is converted into image data or plotter data and distribution-related information pertaining to distribution of the data is added to the image data or plotter data for sending the data.
