DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a data management device of the present invention. The input means 1 is composed of a mouse, a keyboard or the like for inputting various operation instructions. The computing unit 2 analyzes between the server-side device and the client-side device that controls and analyzes the application program, the input device 1, the storage device 4, and the output device 3 through a network 5 (LAN, WAN, etc.). It also controls to send and receive data such as results and image data. The output means 3 is composed of a display for displaying the output accompanying the operation, the analysis result of the finite element analysis and the image, and a printer for printing them.
The storage unit 4 is a main storage unit 4 for temporarily or long-term storage of analysis data, image images, and the like as a result of finite element analysis, and for storing a file management table.
1, an external storage means 42 and an auxiliary storage means 43.

The data management apparatus can operate in a multitasking or multitasking window environment, and can be remotely accessed from a client on the network 5. In such an environment, the server performs finite element analysis at the request of the user on the client side, and outputs the analysis result and image data to the output means 3
Display in the display window of or output to the printer. Of these data, each data required by the user after the analysis is managed by the data management means 6 in the storage means 4.

Next, the data management means 6 will be described with reference to FIG. The data stored in the storage means 4 of the present apparatus and managed by the data management means 6 includes at least the type of analysis,
It is composed of analysis information data such as materials to be used and constraint conditions, analysis result data required by the user, and a file management table 7 required for managing these data. Since the analysis information data has a small capacity, it is output to the external storage means 42 without being compressed, and large capacity data such as image data is compressed and output to the external storage means 42.

If the data of the analysis result is stored in the external storage means 42 one after another in this way, the external storage means 42 will soon become insufficient. In order to avoid this, it is managed when the data stored in the external storage means 42 is written and to what extent it is in use. For this purpose, the file management table 7 (see FIG. 3) for grasping the usage status of the file written in the external storage means 42 is prepared. The file management table 7 is composed of at least a file name, an output date, and usage frequency data indicating the number of times the file is read.
Here, the file name K1. DAT and K2.
DAT and the like represent the file containing the analysis information data of FIG. 2, and the file name K11. GIF and K12. GI
F and the like represent files containing the analysis result data of FIG. The data management means 6 stores the file in the external storage means 42 when storing the file in the file management table 7.
Write 0 as the name of the file to be written to, the output date, and the usage frequency data. After that, each time the user reads the file as needed, the usage frequency data is counted up and updated. Further, the data management means 6
The external storage means 42 monitors a preset capacity (capacity as an absolute quantity, or percentage as a relative quantity),
When the number exceeds the limit, reference is made to the frequency of use of the file management table 7 so that a file with a low frequency of use is output to the auxiliary storage means 43. In this way, when the data is output from the main storage means 41 to the external storage means 42, or from the external storage means 42 to the auxiliary storage means 43, the original data may be automatically deleted.

Although a large amount of data has been described here only for image image data, text data and graphic data have been described.
It can be handled in the same way even if it is a data file.

As described above in the present embodiment, in the data management apparatus of the present invention, the large-capacity data stored in the storage means is always stored in a compressed format, and the external storage means stores a fixed amount of data. When the storage capacity is reached, files with low frequency of use are selectively and automatically moved to the auxiliary storage means, so that the small storage capacity can be used efficiently. Further, since the data stored in the auxiliary storage means has been compressed, the data is temporarily transferred from the auxiliary storage means to the main storage means (decompression processing is performed during that time) to check the contents, and the data is stored. You will see. However, by outputting the analysis information data to the storage means, the contents of the data can be confirmed without performing such an operation, so that the analysis result can be confirmed quickly.

[0012]

As described above, according to the first aspect of the invention, since a large-capacity file is always stored in a compressed format, the amount of data that can be stored in the storage means is greatly improved, and a small storage capacity is required. It can be used efficiently.
Further, the analysis result can be promptly confirmed by outputting the analysis information data to the storage means without compression. Also, claim 2
In the invention, since the external storage means automatically moves to the auxiliary storage means when the capacity exceeds a certain level, the amount of data that can be stored in the storage means is further improved and the storage capacity is used efficiently. be able to. Further, according to the third aspect of the present invention, since the file which is used less frequently is moved from the external storage means to the auxiliary storage means, the storage means can be efficiently managed without reducing the access time of the frequently used data. . Further, according to the invention of claim 4, the original data is selectively and automatically deleted according to the mode designated by the user when the data is output. Therefore, the amount of data that can be stored in the storage means is further improved. The capacity can be used efficiently.
