Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention converts code data created by a terminal device (hereinafter referred to as a client) connected on a network into image data, and the data is connected on the same network. It is intended for a system that can store data in a storage-only device (hereinafter referred to as a server) and perform data service again according to a request from a client.

2. Description of the Related Art As a conventional publicly known example, "Nikkei Byte 19
February 1992, Windows application cooperation mechanism OL
E. , The code data of OA data such as word processor data is converted into image data and handled, OA software is called again at the time of addition / correction, and stored again as image data when the addition / correction is completed. was there. However, when storing the image data, a keyword for searching has to be added every time, and there is a drawback that the usability is poor.

[0003]

SUMMARY OF THE INVENTION As described above, an object of the present invention is to store code data automatically created by a data creator without having to consider a search keyword every time image data is stored. Another object of the present invention is to provide a user-friendly image data server system that can be extracted from the image data and can turn pages quickly as image data.

[0004]

When code data such as word processing data is created and a print instruction is issued, the code data is converted into image data on the client side. This data is taken in by the process inside the client,
At the same time, keyword data for retrieval is extracted from the code data. (Keyword extraction technology is a known technology.) When transmitting image data for storage to the server side, by adding the extracted keyword, the server side becomes aware of OA data attributes and the like. It becomes possible to handle as one image data without performing. This transmitted keyword can be applied to a full-text search technique which is a known technique, and a high-speed search service can be provided.

[0005]

When the creation of the code data is completed on the client side, the same process as the data printing process (image data conversion) is performed, and the process of capturing this image data and transmitting it to the server is performed. At this time, a process of extracting a search keyword from the original code data is performed, and the keyword and image data extracted here are transmitted to the server and stored.

[0006] The server collectively manages the extracted keyword data, and a full-text search becomes possible at the request of the client. The creator of the code data can easily determine the search keyword, and the user-friendly image data service is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a diagram showing the system configuration of the present invention. Reference numeral 112 denotes a terminal device (hereinafter referred to as a client) having an OA function such as a word processor function, and 12 is image data for fetching and storing data created on the client side as image data and servicing the image data according to a request from the client side. A server (hereinafter, referred to as a server) 11 is a network (hereinafter, referred to as a LAN) that connects the client and the server. 15 is L in the server
Adapter that controls the interface with AN (NWC)
Here, 13 is a management processor (CPU) that controls the entire server, 14 is an image processor (IP) that controls the compression / decompression processing of image data, and 16 is a search processor (SE) that performs search processing with a specified keyword. ), 17
Is a memory (VM) for temporarily storing image data in the server, 18 is an adapter (ODA) for controlling an optical disk which is a storage medium of image data, 110 is an optical disk, and 19 is storage of code data such as keywords. An adapter (DKA) for controlling a magnetic disk as a medium, 111
Is a magnetic disk, and 10 is an internal bus of the server.

An OA document created on the client side (a document created by a word processor or the like) is converted into image data and transmitted to a server via a LAN together with a keyword. NWC receives this data and stores it in VM,
The CPU is notified that image data has been received. CPU
Instructs the IP to compress the image data. IP is V
The image data in M is compressed and the compressed data is stored in the VM again. During this time, the CPU instructs the DKA to store the keyword sent from the client as a document (a set of image data in a certain unit, in a word processor, a name added to a document created over a plurality of sheets). To do. The DKA stores the document name and the keyword in the magnetic disk according to the instruction of the CPU. When the image compression by IP is completed, the CPU instructs the ODA to store the image data. Accordingly, the ODA stores the compressed image data on the optical disc.

When referring to OA data on the client side, the keyword to be referred to is transmitted from the client side to the server. When the CPU receives this, the CPU instructs the SE to search for the document name having the specified keyword, and the SE outputs the document name roughly corresponding to the keyword to the VM. The approximate document name is returned to the client side and waits for the document name instruction from the client side. When the document name is designated by the client side, the server side reads the designated document data (image data) from the optical disc, performs decompression processing by IP, and then transmits it to the client side. The client receiving this data displays this image data on the display screen.

FIG. 2 is a diagram showing processing on the client side when storing image data in the present invention. Reference numeral 21 is OA data created on the client side, and this data is converted into image data (image data) at the time of storage and transmitted to the server. At this time, the image may be compressed and transmitted as in the process of 24. At the same time as the conversion process to the image data, the keyword extraction 22 is performed from the OA data. The keyword 27 extracted here and the control information 26 such as the image data 28 and the document name described above are added and transmitted to the server as an information group of 25.

FIG. 3 shows an example of keyword extraction processing. A word that can be a keyword is extracted from an original text created by a word processor or the like and used as a keyword of the created data. In the example of FIG. 3, the keywords are “FIG. 3.1” and optical disk ”.

Keywords and image data on the server side are separately managed as shown in FIG. In the present invention, the information managing the keyword data (hereinafter referred to as the code data section) is stored in the magnetic disk 111, and the image data is stored in the optical disk 110. When a keyword for search comes from the client side, SE is searched and the approximate code data part is stored on the VM as it is. Since this data includes an image pointer indicating the storage location of the approximate image data, the CPU on the server side
Can easily know the storage location of the image data. According to the request from the client side, the server decompresses the image data and returns the image data to the client side.

[0014]

According to the present invention, since OA data is handled as image data on the server side, it is possible to display the created data at high speed such as high-speed page turning. Further, since the server has a large-capacity storage medium, it is not necessary to have a large-capacity storage medium for performing high-speed image processing on the client side.

Further, since the keyword is extracted from the data when it is stored in the server, it is not necessary for the client to consider the keyword in the created data.
