Abstract

A virtual geographic spatial object generating system which is capable of meeting various retrieval conditions requested from a client, wherein a profile ID for each user is read in response to a log-in request from the client, while a script corresponding to the profile ID is read from a script file at an application server. By making use of the virtual geographic spatial object generating operator (hereinafter referred to simply as geographic operator) of this script, a data base server is accessed and a processing is performed so as to generate a virtual geographic spatial object. In this manner, only through a connection with the application server, various data base servers can be accessed and the operation for each user can be performed.

Claims

1. A virtual geographic spatial object generating system comprising;

process-executing means for executing a procedure based on a content of message from a client;

ID notification means for reading a profile ID corresponding to an individual user in response to a log-in request from the client and notifying the profile ID to said process-executing means; and

processing means for generating a virtual geographic spatial object by performing a processing based on said profile ID.

2. The virtual geographic spatial object generating system according to claim 1, which further comprises;

position-informing means for notifying information on a stored position of a virtual geographic spatial object generating script (hereinafter referred to simply as a script) based on the aforementioned profile ID; and

virtually generating means which reads the script from a script file on a basis of an input retrieval condition and said profile ID and generates geographic operators representing an operation using one or more operands from said script;

wherein said processing means is designed to request a retrieval to a data base server depending on a kind of said geographic operator thus generated and to perform a processing based on said geographic operator.

3. The virtual geographic spatial object generating system according to claim 2, wherein said position-informing means is designed to notify information on a stored position of attribute information corresponding to said profile ID.

4. The virtual geographic spatial object generating system according to claim 2 or 3, which further comprises server access means for accessing the data base server according to the script and based on the retrieval condition in response to a request from said processing means.

5. A computer-readable recording medium which is recorded with a program for enabling a computer to function as the virtual geographic spatial object generating system as claimed in claim 1.

6. A computer-readable recording medium which is recorded with a program for enabling a computer to function as the virtual geographic spatial object generating system as claimed in claim 2.

7. A computer-readable recording medium which is recorded with a program for enabling a computer to function as the virtual geographic spatial object generating system as claimed in claim 3.

8. A computer-readable recording medium which is recorded with a program for enabling a computer to function as the virtual geographic spatial object generating system as claimed in claim 4.
