1 is a diagram showing the overall configuration of a distributed remote education system using the Internet according to the present invention, which comprises an integrated customer support server 100, a data storage architecture 200, and a client 300.

The integrated customer support server 100 is connected to the Internet 400 through an Internet host, the servlet engine 120 for operating the servlet interworking with the web server 110 and the web server and the JSP engine for operating the JSP ( 130, and a second server area including an EJB component such as a session bean 160 and an entity bean 170 and a server program 150 such as a web application server, including a first bean area including a Java bean 140 that is a recyclable component. Is done.

The data storage architecture 200 is a storage of data warehouses and data marts in a distributed environment, and other data stores.

The client 300 displays various Internet devices 310 of the education information user who can access the integrated customer support server 100 through the Internet 400 by using a modem or other Internet communication means, and the mediated information. It includes a user interface (320, 330) responsible for two-way communication.

The Internet device 3100 at the client 3000 includes a client program 330 and the protocol for communicating using HTTP, HTTPS, WAP, and at the same time on the integrated customer support server via Java RMI or other J2EE and J2ME architectures. A user device with a built-in client program 320 that communicates with an application.

2 illustrates functional blocks of a client program using HTTP, HTTPS, and WAP.

In the client program using the HTTP, HTTPS, and WAP, the education information user requests the education information from the web server 110 through the browser 330 using the Internet device 310. The web server 110 delegates control in the server area to the servlet 120 to process a complex request of the user and to respond to a web object suitable for each corresponding protocol.

The servlet 120 parses and processes the request stream of the education user in order to form a response stream suitable for the browser 330 and the internet device 310 which are the client program of the requesting user. It acts as a controller and reflects it in the JavaBean 140 which is a model.

The Java server page 130 serves as a VIEW in the MVC pattern of FIG. 4 to create a screen to be shown to the user, and the JavaBeans provide a way to access the actual training data handled by the servlet and the Java server page. It serves as a model to provide. As the architecture-based educational information application applying the MVC pattern as described above, it responds efficiently to complex and huge on-offline educational information requests.

In the client program using the Java RMI and other J2EE and J2ME architecture, the education information user can overcome the disadvantages of the client / server environment and efficiently access vast educational information through a system composed of a three-layer web architecture as shown.

As shown in FIG. 3, the presentation layer of the web application constituting the integrated education system according to the present invention includes a static web object, the servlet 120, and a Java server page 130 when composed of general HTML. The training data of the server is accessed through the dynamic web object created by the server. In addition, by constructing web objects with XML and WML, which are extended notation languages, it is possible to logically implement various educational information and to access educational data through wireless devices.

In the three-tier web architecture, the server side EJB server is responsible for middleware functions such as transaction, security, and database connection pooling, and the enterprise JavaBeans 160 and 170 are responsible for the business logic to be implemented in the integrated education system of the present invention. .

The integrated customer support server 1000 of FIG. 1 processes various requests of a client layer by a web application using an MVC architecture as shown in FIG. 4.

4 shows the relationship between the components of the MVC pattern.

The MVC architecture of FIG. 4 is a design pattern in which the integrated customer support server 100, which is a web application server, receives an input of an education information user through a screen of the various internet devices 310, and inputs an event or an event. It is optimally designed to display the results again.

In FIG. 4, a model is designed through modeling of real-world data on and off-line of educational information, so that the data can be stored and the data can be efficiently accessed, and the view can train the generated model. The display state is determined using protocols and contents suitable for various Internet devices 3100 of the information user, and the behavior of the education information user is transmitted to the controller. The controller defines the actual behavior of the application in the integrated customer support server 1000 and determines whether the behavior of the educational user received from the view should be reflected in the model and the view that appears as a result of the reflection.

The data storage architecture 200 includes an object relational database server 210, a database linked mail server 220, a directory service server 230 for searching and processing remote distributed resources, and an RMI for processing education information of various heterogeneous formats. / CORBA application, Jini solution to handle the home networking area, and as shown in Figure 5 to build a data warehouse and data mart to support the decision-making of educational information users.

The storage and other data storage architectures 200 of the distributed data warehouse and data mart of FIG. 1 are implemented as an XML storage management system and a remote distributed object server system of FIG. 6 as shown in FIG. 5. The storage management system using the XML stores, retrieves, and manages various types of protocols and a large amount of educational data in the object relational database as the XML document of FIG. 5 on a distributed remote education system to achieve the object of the present invention.

The web object of FIG. 5 is stored in a database while the document object of the XML or other web objects is maintained by the controller of FIG. 4 or converted into a data form. The former is a case of storing a document-centric document, which is stored as a BLOB in an object relational database system. In the latter case, data-centric documents are stored. In the case of XML documents, elements, attributes, texts, and paths are separately stored and managed.

In the data storage method, template-driven mapping between the XML document and the database is performed by an appropriate method in the database to generate different XML documents, and a single XML document may be stored in the database and then regenerated. In order to create an XML document, we use various algorithm-based mapping techniques based on the structural information of the XML document and store it in a database.

On the other hand, the data storage architecture by the remote distributed object server system of FIG. 6 illustrates a distributed environment of the above-described XML storage management system, and also illustrates a storage architecture on a file system without a database system. The remote machine or the local machine of FIG. 6 functions as a server and a client communicating with the Java RMI protocol through stubs and skeleton objects, respectively.
