Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a master download system, a master download network, and a master download method.

[0002]

2. Description of the Related Art At present, computers are used in various fields. However, the use of computers having data resources in a server in a client / server configuration and application programs on a terminal device side is increasing. In conventional systems, a database that is centrally managed on a server is generally searched directly from an application of a terminal device, and it is necessary to access the server every time necessary data search is performed.

[0003]

However, in the conventional system, in the client / server mode, in order for the application program on the terminal device side to access the data resources of the server, the application program must be connected via a line every time the access is made. Since access is required, considering the data transfer speed in the network, it takes time to access, and using a public line increases the line cost, and the access load of data resources to the server is concentrated. The problem arises.

[0004] When an application program accesses a server database from a terminal device (client) to a terminal device (client), a search command in structured introduction language SQL and data of a search result exchange data via a network. For this reason, there is a problem that it takes a long access time, which is one factor that increases the line cost.

An object of the present invention is to provide a master download system, a master download network, and a master download method for searching data at a high speed by minimizing data access processing time by downloading server data to a terminal device. It is in.

[0006]

According to the present invention, there is provided a master download system having a computer serving as a server and a master file means for connecting the computer and storing data transmitted from the computer as a data resource. And a plurality of terminal means connected to the computer by a communication line, and application means for executing a package by using the terminal means in common, and downloading a master file means centrally managed by the computer to the terminal means.

Further, according to the present invention, in order to minimize access to a master file means of a computer, a file having a small variation in data content for reference is automatically transferred from a computer to a storage medium in a local area of a terminal device. And the number of times the terminal device accesses the data resources of the computer is minimized.

[0008] Further, when the terminal device starts the business, the terminal device acquires the data resource of the computer and stores it in the storage medium of the terminal device in the local area. Accordingly, when the terminal device starts the business, the data resources of the server can be automatically acquired and stored in the storage medium of the local terminal. Also, since the data resources of the server are replaced with the latest data, even when the latest information is needed in the local area of the terminal device, the data can be manually searched for.

As described above, in the present invention, in order to minimize the access from the application program of the terminal device to the data resources of the server, the contents of the data are small and the files to be referred to are not changed by the server. By automatically downloading data to the storage medium in the local area of the terminal device and minimizing the number of times the terminal device accesses the data resources of the server, the access load to the data resources of the server is reduced, and the application of the terminal is executed. It is possible to improve the performance and reduce the line cost by reducing the line load.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of a master download system, a master download network and a master download method according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram showing a configuration of a master download system according to an embodiment of the present invention, and FIG. 2 is an explanatory diagram showing a state of a master file of a server and a state of a master file of a terminal in chronological order.

In FIG. 1, the master download system comprises a server (computer device) 1, a master file 2 which is a storage data medium having master data centrally managed on the server 1, and a terminal device 3 for executing an application program. . The terminal device 3 includes a local master file 4 stored in a local area, an application program unit 5 for performing master download, and an application program unit 6 used in common with the other terminal devices 3.

The data resource 2 stores data in which a master file referred to by the application program 6 of the terminal device 3 and a file to be updated are to be stored.
The master download application unit 5 automatically acquires the data stored in the master file 2 and copies the data to the local master file 4 at the timing when the task of executing the application program 4 is started. The application 6 refers to the master file by accessing the local master file 6.

Next, the operation of the master data download system of this embodiment will be described with reference to FIG. In this description, reference is made to the configuration diagram of FIG. When the state of the master file (hereinafter, referred to as master) of the server 1 is A, the operation of the terminal device 3 is started, and the contents of the local master file automatically started by the master download application unit 5 of the terminal device 3 Has the same content as A.

If the master content of the server 1 is updated from A to B at a certain point in time, the local master file unit 4 is not updated in real time. In response to the download instruction, the latest master information is obtained, and the local master file unit 4 is acquired.
Update.

In the present embodiment described above, in order to minimize access from the application program unit 6 of the terminal device 3 to the master file 2 which is a data resource of the server 1, fluctuations in data contents are small and reference is made. Is automatically downloaded from the server 1 to the local master file 4, which is a storage medium in the local area of the terminal device 3, and the number of times the terminal device 3 accesses the data resources of the server 1 is minimized. By doing so, it is possible to reduce the access load to the data resources of the server 1, improve the application execution performance of the terminal device, and reduce the line cost by reducing the line load.

Thus, when the terminal device 4 starts a business, the data resources of the server 1 can be automatically acquired and stored in the local master file 4 which is a storage medium in the local area of the terminal device 3. . In addition, since the data resources of the server 1 are replaced with the latest data, even when the latest information is needed in the local area of the terminal device 3, it is possible to manually search for data.

[0017]

According to the present invention as described above,
Since there is no exchange of structured introduction language SQL statements and data via the network when accessing from the terminal device, the application unit of the terminal device does not need data access via a line, and the application unit of the terminal device side does not need to access data. Processing performance can be improved.

Further, according to the present invention, since data to be accessed from the terminal device to the host side can be minimized, there is an effect that it is possible to prevent a decrease in responce due to insufficient processing capacity of the server. Can be.
