Abstract

A communication system is applicable to communications between client terminals and a server via the Internet, and includes a communication service unit creating a communication interface and a memory region in response to a communication request from a client terminal via the Internet, starting an application program in the created memory region in response to the communication request, sending contents of the started application program to the client terminal, and updating data in the memory region and sending the updated data to the client terminal when the communication request includes data updating.

Claims

1. A communication system applicable to communications between client terminals and a server, the system comprising:

single communication service means for creating a communication interface and a memory region in response to each request item in respective management regions when the server receives request items input from the client terminals and transmitted via the Internet, transmitting, to the client terminals, data acquired from a database server by an application program expanded corresponding to the request item in the created memory region and displaying the data on a screen of the client terminal; and

single application control means for expanding the application program into the memory region, and for creating, in each of the management regions, a database management region having a function for writing in, reading out and updating data for the database server,

wherein the communication service means has;

a function for creating the communication interface and the memory region in response to a new request item input from the client terminals;

a function for determining which communication interface and memory region in the server should be used to meet the request item input from the client terminals;

a function for performing a process for executing connection to the communication interface corresponding to the request item sent from the client terminals and transferring data thereto; and

a function for sending a content processed by the server to a communication interface of a corresponding client terminal, and

updates data of the application program expanded in the memory region which are required to be updated when the request item input from the client terminals has a request for updating the data of the application program which are displayed on the screen of the client terminals, and transmits only the updated data to the client terminals and displays the data on the screen of the client terminals, and

the application control means creates the database management region in a management region in which the communication interface and the memory region are created by the communication service means when the communication service means receives the request item from the client terminals and acquires necessary data from the database server by the database management region, and stores the acquired data in a memory region of a management region corresponding to the database management region.

5. The communication system of claim 1, wherein the server receives a plurality of request items from a first client terminal.

9. The communication system of claim 1, wherein each request item is one of:

a request to communicate with the server, a request to send or receive authentication information, and a request for data from application programs.

2. A communication method applicable to communications between client terminals and a server, the method comprising:

a first step of creating a communication interface and a memory region in response to each request item in respective management regions by single communication service means when the server receives request items input from the client terminals and transmitted via the Internet;

a second step of expanding each application program corresponding to the request item in the memory region created in the first step by single application control means;

a third step of creating a database management region having a function for writing in, reading out and updating data for a database server in a management region in which the communication interface and the memory region are created by the communication service means through the application control means, acquiring necessary data from the database server through the database management region and storing the acquired data in a memory region of a management region corresponding to the database management region; and

a fourth step of transmitting the data acquired from the database server by the expanded application program to the client terminals and displaying the data on a screen of the client terminals through the communication service means,

wherein the communication service means updates data of the application program expanded in the memory region which are required to be updated when the request item input from the client terminals has a request for updating the data of the application program which are displayed on the screen of the client terminals, and transmits only the updated data to the client terminals and displays the data on the screen of the client terminals.

6. The communication method of claim 2, wherein the server receives a plurality of request items from a first client terminal.

10. The communication method of claim 2, wherein each request item is one of:

a request to communicate with the server, a request to send or receive authentication information, and a request for data from application programs.

3. A computer readable non-transitory storage medium storing a communication control program which executes the steps of:

creating a communication interface and a memory region in response to each request item in respective management regions when a server receives request items input from client terminals and transmitted via the Internet to the server by installation into the server;

expanding each application program corresponding to the request item in the created memory region;

creating a database management region having a function for writing in, reading out and updating data for a database server in the management region in which the communication interface and the memory region are created and acquiring necessary data from the database server by the database management region, and storing the acquired data in a memory region of a management region corresponding to the database management region;

transmitting the data acquired from the database server by the expanded application program to the client terminals and displaying the data on a screen of the client terminals;

updating data of the application program expanded in the memory region which are required to be updated when the request item input from the client terminals has a request for updating the data of the application program which are displayed on the screen of the client terminals; and

transmitting only the updated data to the client terminals and displaying the data on the screen of the client terminals.

4. A non-transitory memory medium storing the program which is defined in claim 3 and is readable by a computer.

7. The computer readable non-transitory storage medium of claim 3, wherein the server receives a plurality of request items from a first client terminal.

8. The non-transitory memory medium of claim 4, wherein the server receives a plurality of request items from a first client terminal.

11. The computer readable non-transitory storage medium of claim 3, wherein each request item is one of:

a request to communicate with the server, a request to send or receive authentication information, and a request for data from application programs.

12. The non-transitory memory medium of claim 4, wherein each request item is one of a request to communicate with the server, a request to send or receive authentication information, and a request for data from application programs.
