Abstract

PURPOSE:To decrease the quantity of data transferred between a retrieval processing computer and an input/output terminal for retrieval data, by providing additionally said input/output terminal part to a data storing part and independently of a retrieval processing computer. CONSTITUTION:When data are supplied to a system, these data are supplied from an input part of an input/output terminal 3 for retrieval data and stored in a disk device 4. At the same time, the information on the data storing position is transferred to a retrieval processing computer 2. The computer 2 handles the information on the storing position like conventional retrieval data. When the stored data is retrieved, a retrieval indicating terminal 1 gives an indication to the computer 2 for the retrieval data. Thus the computer 2 retrieves the information on the data storing position and transfers it to the terminal 3. The terminal 3 reads the retrieval data out of the device 4 based on the received information on the data storing information and delivers it to an output part.

Description

TECHNICAL FIELD The present invention relates to a data retrieval system, and particularly to a data retrieval system suitable for use when the amount of search data per item is large, such as image data.

In conventional data search systems, the search processing unit consisting of a computer has a data storage unit inside it, and therefore all input data from the search data input/output unit must be stored in this data storage unit. There is.

Therefore, when the amount of data is huge, such as image data,
The increased data transfer time greatly contributes to the increase in overall search time, making it difficult to perform high-speed searches.

The present invention has been made to solve the drawbacks of the conventional systems described above, and its purpose is to separate the data storage section from the search processing section, so that the search processing section can be separated from the search processing section. It is an object of the present invention to provide a data retrieval system that enables high-speed data retrieval by reducing the amount of data transferred between a search data input/output unit and a retrieval data input/output unit.

11dan11 The data search system according to the present invention includes a search instruction unit that instructs data search, a search processing unit that executes data search processing according to the data search instruction, and a search data input/output unit that processes input and output of search data. The present invention is directed to a data search system having a data search system, and its feature lies in that a data storage unit for storing search data is provided separately from the search processing unit.

Point 1” Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a schematic block diagram of an embodiment of the present invention. In the figure, 1 is a search instruction terminal that instructs data search, and 2 is a search processing computer that executes data search processing. 3 is a search data input/output terminal that controls input/output of search data; 4 is a disk device for storing search data; this disk device 4 is provided separately from the computer 2; The configuration is provided in conjunction with the output terminal 3.

FIG. 2 is a flowchart showing the operation of the system of FIG. 1, and (A) shows the operating procedure when introducing data into the system. Referring to this Figure 2 (A),
When inputting data, input the data from the input section of the search data input/output terminal 3, and transfer the input data to the disk drive [! Store in 4. At the same time as this storage, data storage location information is transferred to the search processing computer 2. This calculation 1fi
2, the storage location information is handled in the same way as conventional search data.

Next, the search process for this stored data will be explained using the operational flow shown in FIG. 2(B).

A search instruction terminal 1 instructs a computer 2 to search for data. This computer 2 searches for storage location information of the specified search data and transfers it to the search data input/output terminal 3. The search data input/output terminal 3 reads the search data from the disk device 4 based on the received storage location information, outputs the read search data to the output section, and the search ends.

By doing this, only a small amount of storage location information is required as data to be transferred from the search processing computer to the search data input/output terminal, so the ratio of data transfer time to search time becomes extremely small.

As stated in the RJ item and January paper, according to the present invention, the search data input/output terminal section is provided with a data storage section to make it independent from the search processing computer, so that it is independent from the search processing computer. The amount of data transferred to and from the search data input/output terminal is reduced, making it possible to suppress an increase in search time.

This is particularly effective when the amount of search data is enormous, such as image data.
