2. Description of the Related Art Conventionally, in an ASP (application service provider) that lends one application software to a plurality of companies on a time basis, an application software execution environment is prepared for each lending company as an application software lending method. Was a common practice. For example, business application software such as salary is constructed on the assumption that one application software is used by one company, as in the client / server system.

[0003]

Therefore, when a plurality of companies use business application software at the same time via a network, the conventional software cannot cope with the business application software. It was necessary to prepare an execution environment, which was a factor in increasing the cost on the system.
In addition, business application software such as salary secures security by setting usage rights for users who use the software. However, if the user does not use the user directly and the agent performs the processing, an operation is performed such that the agent borrowing the user information of the original user uses the information. For this reason, even when a security system is prepared in the business application software, the security system does not consider the operation side, and there is a problem that security cannot be ensured.

[0004] Further, a business entity that performs processing on behalf of a plurality of companies requires the use authority information of each company outsourcing the business, and thus there is a problem in information leakage. Further, conventional business application software sets usage rights for each company, and does not have a function of generating information such as usage time, usage amount, and usage fee by using the software. Therefore, when the conventional business application software is used for lending to another person, there is a problem that a fee system cannot be set according to the usage time.

The present invention has been made in view of the above circumstances, and it is possible to easily share one application software among a plurality of users, to ensure the security of each user, and to secure the security of each user. It is an object of the present invention to provide an application software sharing system that can perform billing.

If the content is not correct, the process proceeds to step S3 to display an error message and terminate the process. If the content is correct, the process proceeds to step S4. Item information permitted by the user classification information of the user who has logged in from the item database 14b, and a menu screen is displayed on the display device 27 of the user terminal device 2 (step S5). It registers login information such as its own company code, user ID, and login date and time in the service providing information database 14d. Next, in step S7, the user selects a function to be used from the service items displayed on the menu screen, and in step S7, the selected information is registered in the service provision information database 14d.

Next, in step S9, the time when each service item is used until the user logs out, the logout date and time when the user logs out, and the like are stored in the service providing information database 14d, and the login / logout processing ends. The same processing is performed when the person who intends to use the application software is a substitute. In this case, services provided by the user classification of the agent are restricted. That is, in the case of payroll application software, the original user (for example,
Service items that only management should know (for example,
With respect to salary trends, etc., agents (for example, accounting staff or outsourcing companies) cannot use them.

Next, the business process by the payroll application software will be described with reference to FIG. In step S11, the CPU 13 as an acquisition unit
In the business process applied by the selected service item, it is determined whether or not the information necessary for the process is common among the users, and if it is determined that the information is common, the step is performed. The process proceeds to S12, but if not, the process proceeds to step S13. In step S12, the corresponding data is obtained from the common information database 14f, and the process proceeds to step S14.

In step S13, a unique file connection process for acquiring information unique to the user is performed. In the unique file connection processing, the CPU as a session management means

In step S14, the CPU 13a as an execution means performs a business process using the data obtained in step S12 or S13 according to the application program. In step S15, a process of transmitting the processing result generated by the business process to the user terminal device of the user is performed, and the process ends.

Next, charging / billing processing for a service on the side that provides the function of application software will be described with reference to FIG. First, step S2
In step 1, the service provision information of the user stored in the service provision information database 14d and the unit price stored in the item unit price database 14c are acquired. Next, in step S22, the CPU as a service charge calculating unit
13a, the service charge is calculated by a predetermined formula using the service item in the service provision information, the use time, and the charge unit price of each service item.

In step S23, billing information necessary for billing including a service fee is created by the CPU 13a as billing information creating means. In step S24, the created billing information is stored in the billing information database 14g. Items required as information to be retained include the company code to be billed, the billing month to be billed, the billing period to be billed, the use item code, the unit price set for each billed party, the unit price basis, and the amount used , Usage amount, etc.

In step S25, the report server 15
Creates a bill based on the billing information stored in the billing information database 14g. In this bill creation process, the form definition file of the corresponding company is called from the form definition file stored in the unique information database 14f, and the bill information is allocated and created. In step S26, the created billing data is transmitted to the user terminal device 2, and the billing / billing process ends.

According to the application software sharing system 100 according to the present invention described above, the information necessary for using the application software is:
Information is divided into common information common to users and unique information unique to each user. When executing application software, necessary information is obtained from the common information database 14e or the unique information database 14f, and further information to be used is obtained. In the case of the unique information, the unique information of the user stored in the unique information database 14f is selected and acquired based on the user information of the user stored in the user information database 14a. Since the application software can be shared by a plurality of users, the application software can be rented out at a lower cost. In particular, since payroll application software, which is susceptible to law revisions, undergoes frequent upgrades, and requires a great deal of time for system maintenance and operation, is shared, the total system cost can be reduced.

Even when the agent performs processing using the application software on behalf of the user, by setting the user category to an appropriate range, the agent for processing the service item that the user wants to keep secret can be used. As a result, the security of the sharing of application software can be ensured.

Furthermore, since only the unique information permitted by the authentication information such as the DB user ID and the DB password is obtained from the unique information database 14f, only the unique information permitted by the authentication information is obtained from the unique information database 14f. As a result, the security of the unique information can be secured.

In addition, the service providing information database 1
The service charge is calculated by a predetermined calculation method using the service provision information stored in 4d and the item unit price for each service stored in the item unit price database 14c, and the billing information including the calculated service charge is calculated. Since the created billing information is output, the billing of services to each user when the same application software is shared is easily performed.

Although the embodiments of the present invention have been specifically described above, the present invention is not limited to the above-described embodiments, and can be modified without departing from the gist thereof. For example, in the present embodiment, the user information database 14a is described with the concept of a single file for the sake of convenience, but this is physically or logically divided or integrated with other information. In this case, if the record items described in the present embodiment exist, they are included in the scope of the present invention. Further, in the present embodiment, in the present embodiment, the common information database 14e and the unique information database 14f for information that is not common between users have been described separately. However, the present invention is not limited to this. Even if the database 14e does not exist, those having a process corresponding to the unique file connection process are within the scope of the present invention.

Further, in the present embodiment, the name of the company code is used, but this is not a code for a specific one company, but a user of an application software function provided such as an individual or an organization. Depends on the unit used. Further, in the present embodiment, the company code is one of the items held in the item database 14b. However, if the provided service does not differ between users, the company code is stored. Becomes unnecessary. Further, in this embodiment, the company code is one of the items stored in the item unit price database 14c, but if the unit price of the provided service does not differ among users, the company code in the item unit price database is used. Is no longer required. In addition, the unique information database may store not only user-specific data but also, for example, user-specific application logic in a parameter setting method, and may read out and perform calculation processing as needed.
In addition, the application software for payroll calculation is exemplified, but it is a matter of course that the application software is not limited to this.
