Abstract

PROBLEM TO BE SOLVED: To provide an intranet system which can obtain work environment corresponding to the work content and the work performance of a user. SOLUTION: An object directional data base is given to a server-side. A server generates a user class having a user name, an access level to data and work environment fitted to the level of the user. A user-side logs in to the server through a communication route different from the HTTP(hyper text transfer protocol). The server retrieves a user object and sets access right for every user in accordance with an access level. The user-side retrieves the data base in accordance with work environment. The server defines a list storing a retrieval result in the user class, stores the object derived from it in the data base for every user and links the retrieval result to the retrieval result list.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a WWW (World WideW) based on a network loadable program.
eb) and an intranet system using an object-oriented database.

[0002]

2. Description of the Related Art With the spread of the Internet, higher performance of client machines, and higher functions of viewers, information transmission on the WWW has been actively performed.

Recently, WWW has begun to be considered as a kind of database from the viewpoint of merely transmitting information. Intranet systems using the WWW are beginning to be constructed as systems that link databases and share various in-house information. already,
Some relational databases are being commercialized as intranet-compatible databases.

Further, a network-loadable programming language such as Java for loading and executing a program from a server has been developed. HTML (HyperTe), which is currently frequently used by a network loadable program (hereinafter referred to as an applet).
xtMakerUpLanguage) In addition to displaying information in a document, a more advanced intranet system is being considered.

[0005] Also, object-oriented technology, which was previously avoided due to the large processing load, has been replaced by conventional software technology in terms of the reproductivity, rationality, expandability, security, etc. of its architecture. Due to its superiority, higher performance and lower cost of computers, it is becoming the core of future software technology.

[0006] Also, because of the ease of handling irregular data such as moving images and sounds, an object-oriented architecture has begun to be used as a technique for handling data including a database.

[0007]

At present, in a system using WWW such as an intranet system, a server H
TTP (HyperTextTransferPro
Tocol), the connection to the server is disconnected every time. Therefore, it is difficult to specify the user.

[0008] In a system using a database, it is common to set an access right to data for each user. However, it is impossible to set an access right in a system using HTTP where it is difficult to identify a user. Especially,
This is a fatal flaw in an intranet system that discloses an internal information database.

[0009] Furthermore, the method of using the system must be different depending on the user. For example, a person related to human resources would search for personnel information, and a person related to sales would search for business information. In addition, there may be users with different working abilities, such as those who are unfamiliar with computers and those who can perform advanced searches. Therefore, the work environment should be changed according to the user's work ability.

[0010] However, since it is impossible to certify the accessing user, it is impossible to provide a work environment according to the work purpose and work ability of the user.

[0011] Further, while using the system, there is a case where it is desired to perform a refined search for performing another search for the searched result.

However, in a system using HTTP, the connection is disconnected each time, so that it is impossible to hold the search result. That is, a narrow search cannot be performed. It is possible to send all the search results back to the client via an HTML link or the like, and perform a refined search while holding the search result link on the client side. However, the search results can all be converted into HTML documents or a large amount of communication data. Because you have to send things,
This approach is not practical.

An object of the present invention is to provide an intranet system capable of obtaining a work environment according to the work content and work ability of a user.

It is another object of the present invention to provide an intranet system that makes it easy for a user to narrow down a search.

[0015]

According to the present invention, an object-oriented database is provided on a server side, and a user can communicate with a user by utilizing a WWW based on a network loadable program.
In an intranet system for performing information retrieval by TTP, the server uses an object-oriented program to provide an HTML document that provides a user name, an access level to data in a database, and a work environment adapted to the level of work content and work ability of the user. A user class is created for each user having a user name or an applet name, and the user logs in to the server through a communication path different from the HTTP, and the server uses the user name of the user class to log in to the server. An object is searched, the searched object is added to a user list, access rights are set for each user according to the access level, the work environment is sent to the user side, and the user side transmits a database according to the work environment. Characterized by performing a search for

Further, the server defines a list for storing search results in the user class, stores objects derived from the list in a database for each user, and links the search results to the search result list, thereby narrowing down the search. It is characterized in that the previous search result at the time of reconnection can be referred to.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) In constructing an intranet system using WWW and an object-oriented database, this embodiment provides a user authentication method.

First, a user class is created by an object-oriented program as shown in the following table. The user class defines a user name, a database access level, and a work environment name (HTML document name or applet name). A user who can connect to the object-oriented database is registered by using it.

[0019]

[Table 1]

Next, as shown in FIG.
A communication path with the server is secured separately from TTP. The user starts access by logging in to the server. Search the user object by user name on the server side,
Processing proceeds in a format that communicates with the object.
For access to the database, an access right is set for each user according to the database access level defined for the user object. The flow of the login process will be described below with reference to FIG.

(S1) The client loads the log-in applet from the server.

The log-in applet created by the network loadable program is loaded. This applet has a function of sending the input login name to the server, waiting for the answer (work environment HTML document name), and loading the work environment. (S2) Enter the user name and send it to the server.

The client sends the user name input to the login applet to the server and waits for an answer to the login process.

(S3) The server acquires the user name.

The server is always in a state of waiting for connection of a communication line, and when a connection request is received from a client, a new object for client connection is created, thereby connecting the line. When the connection is completed, get the user name.

(S4) Search for a user object from the user object list by user name.

From the list of all the user objects stored in the database, the object of the user who has made the login request is searched. The user name obtained at login is used as the search key.

(S5) The searched user object is added to the login user list.

Due to the transaction processing, the pointer of the user object in the database cannot be kept in the memory while the client is connected to the server. Therefore, in the processing after the login processing, the user object must be searched for every access.

Searching for a user object from the entire user list will slow down the processing speed. To avoid this, create a login user list in the database for only the logged-in user. Add the pointer of the searched user object to this list. The poink of the user object is deleted from the list when logging out.

(S6) The work environment registered in the user object is sent to the client.

Several kinds of work environments corresponding to the work contents and work ability levels of the user are prepared, a work environment name for executing the work environment on the client is extracted from the user object, and the answer of the login processing is sent to the client. As

(S7) Load the work environment received by the client.

The work environment sent from the server is loaded from the server. In case of HTML document, use WW
It is displayed on the W viewer. For applets, load according to the network loadable language.

As described above, the user is authorized by logging in to the server. Further, by using the user object prepared for each user, it is possible to set the access right of the database and to provide a work environment suitable for the work content and work ability.

Returning to FIG. 1, the processing after login uses HTTP only when displaying data, and all requests to the server such as search commands are performed by communication between the applet and the server program. Since the user object and the communication path in the database are uniquely determined for each user, it is possible to use the intranet system while specifying the user.

(Second Embodiment) This embodiment provides a method for holding a search result of a user object by the server.

The search result list slots are prepared for the user classes shown in Table 1 above. By adding the pointer of the searched object to the list, the search result can be permanently stored in the database. By performing another search on this search result list, a narrow search can be performed.

Further, this processing can be performed only by adding the pointer of the object searched in the database. This eliminates the need to copy the search results, so that processing can be performed at a high distance without consuming extra memory.

Also, the search results need only be sent to the client at the necessary places, and there is no need to create unnecessary HTML documents or send a large amount of data such as sending all the search results.

Further, by retaining the search results in the database, it is possible to use the previous search results even if the connection is lost or reconnected.

[0042]

As described above, according to the present invention, the following effects can be obtained.

(1) By defining a user class, it is possible to provide a work environment corresponding to the user's plan contents and the level of work ability.

(2) Since the user object has an access level to the database, the access level to the database can be set for each user.

(3) By keeping a list of logged-in user objects separately from all user objects, it is possible to reduce the search time for user objects in the processing after login.

(4) Refine search can be performed by having a list in which search results are stored in the user object. Since a search result can be obtained only by adding a pointer to the database of the server, processing such as data copying can be omitted, and communication data can be reduced as much as possible. By holding the search results in the database, the search results from the previous connection can be used when reconnecting.
