ABSTRACT:
CROSS REFERENCE TO RELATED APPLICATIONS
This application is based upon and claims priority from Japanese Patent Application 8-077939 filed Mar. 29, 1996, the contents of which are incorporated herein by reference herein.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to two-way communication systems which transfer information, such as search conditions and search results, between a client and a server in response to requests from the client. Namely, the present invention relates to, for example, a local-file-transfer method and a local-file-transfer system used in a WWW (world wide web) client-server system. The present invention particularly relates to a local-file-transfer method and a local-file-transfer system used in the WWW client-server system which allows large quantities of data to be transferred from a WWW client to a WWW server connected through the Internet.
2. Description of the Related Art
Keeping pace with recent developments of the Internet, WWW client-server systems have been increasing in the number of business application fields in which they can be used. Various execution and search requests issued from a WWW client to a WWW server involve sending large quantities of data, especially in the case where a search request composed by the client and to be sent to the server requires a significant amount of data for its definition. What is needed is a local-file-transfer method and a local-file-transfer system which allow such massive data transfer from the WWW client to the WWW server.
Special types of search request information, such as genetic information, provided by a server device requires a long search-condition clause to be entered at a client device. Such a long data sequence, is generally not suitable for keyboard data entry. What's needed is the ability of storing information in a file in the client device in advance, and transferring the information to the server device at the time of the search, so that the server device can carry out the search for requested information based on the transferred file.
Typically, data transfer from a client device to a WWW server connected through the Internet requires data entry into the client device, and such data entry is typically carried out using the following methods.
A first method of data entry is keyboard entry of the data by an operator working at the WWW client device. The data is entered into an input field on the display which typically displays an HTML (HyperText Markup Language) menu transferred from the WWW server, and, then, the entered data is sent to the WWW server through the Internet.
A second method of data entry is to copy (cut and paste) data to an input field from a window on the same display. In this case, the window shows a list of candidate data for transfer to the WWW server.
The first method of keyboard data entry into the input field is prone to key-touch errors during lengthy data entry, and is also time consuming.
The second method of copying (cutting and pasting) data into the input field from a window on the same display is time consuming in terms of copy-range selection, and, also, is susceptible to possible erroneous character transformation during the copying process.
Accordingly, there is also a need in WWW client-server systems for a local-file-transfer method and a local-file-transfer system which allow massive data transfer from a client to a server without imposing an onerous work load on an operator.
Also, there is a need in the WWW client-server system for a local-file-transfer method and a local-file-transfer system which allow data to be transferred from a client to a server by identifying data on a client display, extracting a relevant file from a client memory device, and sending the relevant file to the server, to request the server to register the file, to execute the file, or to search registered files.
Further, there is a need in the WWW client-server system for a local-file-transfer method and a local-file-transfer system which allow an execution-request transfer from a client to a server to be made by entering the execution request on the client display and sending the request to the server, or by identifying the execution request on the client display, extracting file-stored execution requests from a client memory device, and sending the file to the server.
Moreover, there is a need in the WWW client-server system for a local-file-transfer method and a local-file-transfer system which allow search-condition transfer from a client to a server to be made by entering the search conditions on the client display and sending the search conditions to the server, or by identifying search conditions on the client display, extracting file-stored search conditions from a client memory device, and sending the file to the server.
Also, there is a need in the WWW client-server system for a local-file-transfer method and a local-file-transfer system which can issue a completion message after completion of a data transfer from a client to a server so as to inform the server of the end of the transfer.
Further, there is a need in the WWW client-server system for a local-file-transfer method and a local-file-transfer system which allow a server to store client-sent information, to carry out client-issued requests based on client-registered information provided on a file-unit basis, and to allow the server to notify the client of the execution results.
Moreover, there is a need in the WWW client-server system for a local-file-transfer method and a local-file-transfer system which allow a server to generate search parameters based on client-sent search conditions to search for client-registered information provided on a file-unit basis.
Also, there is a need in the WWW client-server system for a local-file-transfer method and a local-file-transfer system which can request the server to eliminate transferred information when execution results notified by the server are satisfiable.
SUMMARY OF THE INVENTION
Accordingly, it is a general objective of the present invention to provide a local-file-transfer method and a local-file-transfer system which can satisfy the needs described above.
It is another and more specific objective of the present invention to provide a local-file-transfer method and a local-file-transfer system which allow data transfer from a client to a server by identifying data on a client display, extracting a relevant file from a client memory device, and sending the relevant file to the server, in order to request the server to register the file, to execute the file, or to search registered files.
It is a further objective of the present invention to provide a means for preparing lengthy data in advance at the client display and then transferring such data from the client to the server in a way that significantly reduces the user's work load.
In order to achieve the above objects, the present invention provides a method and system of transferring information from a client to a server in a client-server system which achieves significant reduction in operator work load in comparison with conventional keyboard entry. According to the present invention, the data to be transferred to the server is prestored in a file in the memory media of the client. A display is transferred to the client from the server, the display providing fields for entering data. The file in the client's memory media is subsequently entered on the display provided from the server. The file is transferred to the server at the time of search. The server device carries out the search for requested information based on the transferred file data. A search query can be constructed at the client based on combined search conditions made up from search-condition file names and search condition data previously transferred to the server.
Another aspect of the present invention is that a file name of a file is indicated on a display which is created based on menu information provided from the server. After indicating that file-unit-based informa
