DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a server access device, and more particularly, to a server distributed in a network,
That is, a database, a host for communication between personal computers, and WWW (Wold Wide Wed).
b) A server access system that supports access to a server or the like.

[0002]

2. Description of the Related Art Conventionally, as a technique for supporting access to a server, a technique of notifying a server user of a change in data on the server when the data on the server has been changed, or a standard command input when using the server. There is a technology to act for such.

[0003] For example, as a technique for notifying a change in database data, there is a technique disclosed in Japanese Patent Application Laid-Open No. 4-71067 and a technique disclosed in Japanese Patent Application Laid-Open No. 7-44441. In the former technique, when a data change occurs, a change notification is sent from a system to a user to an application accessing data in a database.

In the latter technique, when data is changed, a change notification is issued from the system to a user who is referring to a file associated with the changed data. In both of the above technologies, the notification destination of the change notification is a specific user, and the notification is also a fixed form.

On the other hand, as a method of reducing a user's input burden when accessing a server, there is a macro function incorporated in communication software of a personal computer or the like. In this function, the user describes the input commands to the system in a file in advance, and automatically substitutes the command input to the server by the user based on the contents of the file, or data from a specific server. For command input.

[0006]

In the conventional access support technology described above, when a method of notifying a change to an application accessing a database when data is changed, a user who is referencing the data is notified of the change. However, no notification is made to the other users.

Further, in the case of a method of notifying a user who is referring to a related file at the time of data change, a user who has referred to the changed file and a user who has referred to a file related to the changed file are notified. Will be notified, but no other users will be notified. For this reason, the database user cannot receive the change notification unless the access is being executed, and must access the database in order to know the change. When the load on the server is high, the database user knows the change instantly. Can not do.

[0008] Further, none of the above methods corresponds to the case where a new database is constructed, etc.
Change notifications are boilerplate following a system-defined format and are not intended for an unspecified number of users, so they can only be used in a closed world for a specific user of an existing database. Can not.

[0009] Furthermore, in the macro conversion of a command to be used when a user directly accesses a database in a file or the like, a command input proxy is only performed when the character string matches a character string registered in advance. A flexible service that changes the input command with reference to the output result of, for example, the search condition is tight when the search result is 1000 in the database search, but is changed when the search result is 0. It is not possible to use services such as loosening, and the macro must be generated by the user himself, increasing the burden on the user.

[0010] In view of the above problems, it is an object of the present invention to access a server's data even when a server issues only an atypical change notice or when a server does not issue a change notice. Unspecified large numbers of users who have not yet made data can be notified of data change notifications, and at the same time, the system automatically acquires detailed data on changes and presents them to users. An object of the present invention is to provide a server access device capable of presenting data relating to a new database to a user even when the database is constructed.

It is another object of the present invention to provide a server access apparatus capable of performing an optimal input proxy by referring to an output from a server when directly accessing the server.

[0012]

A server access device according to the present invention comprises: an access unit for accessing each of a plurality of hosts; A receiving unit for receiving a change and establishment notification including host information indicating a change source and an establishment source, wherein the extraction unit extracts the host information from the change and establishment notification received by the reception unit.
