Description

Method for exchanging a data between the different kinds web operating systems based on the internet surroundings}

The present invention relates to a method of exchanging data between web operating systems based on an Internet environment, and more particularly, to an exchange web format (XML: eXtensible) for exchanging data formats between web operating systems designed with different kinds. Markup Language (hereafter referred to as "XML") data, as well as providing a set of "framework" that is dedicated to the exchange of XML data to some of the systems, each web designed with this model It is about a method of exchanging data between heterogeneous web operating systems based on the Internet environment that allows operating systems to more easily achieve the data exchange required by the operating systems.

Recently, with the rapid development of technology in the field of information and communication, the use of the Internet is becoming common, and according to the trend of the generalization of the Internet, numerous Internet websites have been widely opened, and accordingly, each Internet website is managed. The importance of web operating systems is also increasing.

For example, Korean Patent Laid-Open Publication No. 2000-37105 "Advertising and shopping system and method using Internet game", Korean Patent Laid-Open Publication No. 2000-37174 "Intermediary for special information exchange and operation method using the Internet", Korean Patent Korean Patent Publication No. 2000-37207 "Method for managing registration of personal information on website", Korean Patent Publication No. 2000-37229 "System and method for advertisement of advertisement through dividend payment service", Korean Patent Publication No. 2000-37242 " Personal portal website operation system and operation method ", Korean Patent Publication No. 2000-37385" Operation apparatus and method of the website related to visual creation ", etc., various examples of the web operation system according to the prior art are disclosed in detail It is.

Recently, as the information exchange problem on the Internet has emerged as an important issue, the problem of how to easily exchange data held by each web operating system has been extensively studied for each conventional web operating system.

However, despite this extensive research, many web operating system operators still do not easily solve the problems associated with "data exchange between each web operating system."

As such, despite various studies, many web operating system operators cannot easily solve the "data exchange problem between each web operating system" in the early stage of Internet introduction, when the data exchange problem did not emerge much. Most operators have made the mistake of building each Web operating system in a different development environment.

If the "data exchange problem between each web operating system" is solved smoothly, each web operating system can gather more data from other web operating systems, or have its own data and other By easily synchronizing data held by web operating systems, it is possible to provide better quality services to users using the Internet.

However, as mentioned above, in the early stage of Internet introduction, since most operators have built their web operating systems in different development environments, at present, each conventional web operating system has a different type of database (D). / B: Data Base (hereinafter referred to as "D / B"), and thus, each of the conventional operators has a huge amount of data when the exchange of data between the web operating systems is realized. While reducing the fact that the profit can be obtained, there is no specific response to this situation.

Accordingly, an object of the present invention is to unify the exchange data format between web operating systems designed with this type, for example, into XML data, in which state each web operating system is based on a series of frameworks for acquiring XML data. By making the process and XML data synchronization process smoothly, each of these heterogeneous web operating systems can be easily exchanged with each other without the need for existing configuration system.

Another object of the present invention is to greatly improve the convenience of Internet users by maximizing the data exchange efficiency between web operating systems designed with this model.

Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

4 is an exemplary diagram conceptually showing a configuration of heterogeneous web operating systems for implementing another aspect of the present invention.

5 is a flowchart sequentially illustrating a data exchange method between heterogeneous web operating systems based on an internet environment according to another aspect of the present invention.

In order to achieve the above object, one aspect of the present invention requires the extraction of XML data (eXtensible Markup Language data) to any source side system, receives the XML data from the source side system, and maps the XML data. Analyzing based on a map file and determining whether or not the XML data is normal based on the analysis result, and when the XML data is confirmed to be normal by this determination process, the XML data is converted to the previous map. Disclosed is a method of exchanging data between heterogeneous web operating systems based on an internet environment including filtering based on a file and storing the data on a target D / B.

Further, in another aspect of the present invention, it is determined whether an update event of XML data has occurred, and when an update event of XML data occurs, an arbitrary target side system to deliver the corresponding XML data update information is selected, and selection is completed. Delivering XML data update information to the target side system, receiving and analyzing the XML data update information delivered through this process, and determining whether the corresponding XML data update information is normal based on the analysis result; If the XML data update information is found to be normal through this determination process, the XML data update information is filtered based on the map file, and based on the filtered XML data update information, the XML stored in the target D / B Data between heterogeneous web operating systems based on the Internet environment consisting of updating data. It discloses an exchange method.

In the present invention, the exchange data format between the web operating systems designed with this model is unified with XML data, and, for example, "XML data, XML data update information, etc., which are in the exchange process, are filtered on a part of each system, By providing a set of "framework" that allows arbitrary choice of target-side systems, web operating systems designed for this model can be provided with an optimal infrastructure "to more smoothly achieve the data exchanges needed for them." Make sure

When this is realized in the technical background, each web operating system of this type can smoothly proceed a series of XML data acquisition process and XML data synchronization process. It is possible to exchange the necessary information more easily without being overwhelmed by the composition system, and eventually, Internet users can easily obtain the effect of maximizing their convenience.

Hereinafter, a method of exchanging data between heterogeneous web operating systems based on an internet environment according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, with the D / B structure of this type, through the present invention, web operating systems that want to perform data exchange form a series of complex communication relationships based on the Internet network.

For example, as shown in FIG. 2, the web operating system A 10 establishes a series of communication relationships with another web operating system, for example, the web operating system B3 20, and the web operating system B3 20. Establishes a series of communication relationships with another web operating system, such as web operating system C2 30.

Here, assuming that the relationship between the web operating systems is "limited to the relationship of the web operating system A 10 and the web operating system B3 20", the web operating system A 10 has a series of It can be defined as a source side system (Source side system) for providing "XML data" to another system, the web operating system B3 (20) is a target side that receives "XML data" from another system according to their needs It may be defined as a target sidesystem.

Of course, the web operating system A 10, which is the source side system, is not only the above web operating system B3 20, but also other web operating systems, such as "Web operating system B1, web operating system B2 .... web operating system Bn. And the like can also form the above-described "target-source relationship".

In contrast, assuming that the relationship between the web operating systems is "limited to the relationship of the web operating system B3 20 and the web operating system C2 30", the web operating system B3 20 is the previous example. Unlike this, it may be defined as a source-side system that provides its own set of "XML data" to other systems, and the web operating system C2 30 provides "XML data" from other systems according to its own needs. Can be defined as the receiving target side system.

Of course, as in the previous case, the web operating system B3 20, which is the source side system, is not only the web operating system C2 30, but also other web operating systems, for example, "web operating system C1, web operating system C3. Web operating system Cn "and the like can also form the above-described" target-source relationship ".

In short, each web operating system to which the present invention is applied can act as a source-side system and a target-side system, depending on the situation.

At this time, one thing to note is that in order for the present invention to be implemented more effectively, the source-target relationship between each web operating system is formed of "a large number of target-side systems that correspond one-to-one to multiple source-side systems". Rather, it is advantageous to be formed of " one source-side system-a number of target-side systems that have a many-to-one correspondence. &Quot;

On the other hand, as shown in the figure, the target side system, that is, the web operating system B3 (20) forms a series of communication relationships with the source server, that is, the first server 12 of the web operating system A (10) An XML data filter unit 23 is arranged.

In this case, the XML data filter unit 23 requests the first server 12 to extract XML data, receives and analyzes XML data transmitted from the first server 12, and based on the analysis result. , Determining whether the XML data is normal or not, filtering the corresponding XML data based on the determination result, storing the XML data in the second D / B 21, and so on, according to an embodiment of the present invention. Lead the entire exchange process, eg data acquisition.

At this time, the first server 12 and the XML data filter unit 23 unify exchange data with each other as "XML data" which is widely known as "the most advantageous for the exchange of structured information." Create an optimal infrastructure environment.

Hereinafter, a data exchange method, for example, a data acquisition method between heterogeneous web operating systems based on an internet environment constituting an aspect of the present invention will be described in detail.

First, the present invention will be described under the premise that "Web operating system A 10 acts as a source side system and web operating system B3 20 acts as a target side system".

In this case, as illustrated in FIG. 3, the map file generation unit 25 disposed in the web operating system B3 20 may include a document type definition (DTD) file (opened in the web operating system A). 13) to the process of loading the web operating system B3 (20) side (step S1).

Subsequently, the map file generation unit 25 loads the D / B schema from the second D / B 21, and then references the DTD file 13 and the D / B schema described above, The process of generating the map file 24 is performed (step S2).

At this time, the map file 24 generated by the map file generation unit 25 may include element elements of the DTD file 13 and elements of a specific table held by the second D / B 21. Contains a set of information that maps fields to each other.

In the state where such a process is performed in advance, the XML data filter unit 23 is an arbitrary program disposed in the web operating system B3 20 or, when the agent requires the storage of specific XML data, the web operating system A In communication with the first server 12 arranged at (10), the first server 12 is requested to extract the XML data (step S3).

When such a request event occurs, the first server 12 proceeds with an arbitrary process, for example, searching for the first D / B 11 to extract the XML data requested by the XML data filter unit 23. The XML data is then returned to the XML data filter unit 23. At this time, the XML data may not necessarily be extracted from the first first D / B 11.

In this state, the XML data filter unit 23 determines whether or not the XML data requested by the first server 12 has been completely received (step S4).

At this time, when it is determined that the XML data requested by the first server 12 has not been completely received yet, the XML data filter unit 23 proceeds to step S5 to maintain a series of standby states.

However, when it is determined that the XML data requested by the first server 12 is completely received, the XML data filter unit 23 uses the aforementioned DTD file 13, map file 24, and the like. After parsing the XML data, it is determined whether the XML data is in a normal state without any damage (steps S6 and S7).

At this time, when XML data is transmitted from the first server 12, for example, when it is determined that a series of damage is received due to adverse effects such as a problem on the network, a problem on the server, and the like, the XML data filter unit 23 ) Proceeds to the above-described step S3, so that the aforementioned XML data transmission process can be repeated once again.

However, in the case where it is determined that the XML data is not adversely affected during the transmission of the XML data from the first server 12 and is not particularly damaged, the XML data filter unit 23 sends the previous map file generation unit 25 to the previous map file generation unit 25. The process of filtering the XML data on the basis of the map file 24 generated by the (step S8).

When the filtering process is completed, the XML data filter unit 23 stores the filtered XML data in, for example, the second D / B 21, so that the web operating system B3 may finally retrieve the XML data of the web operating system A. Ensure stable acquisition.

Next, the present invention will be described under the premise that "Web operating system B3 20 acts as a source side system, and Web operating system C2 30 acts as a target side system." The flow shown in FIG. 3 applies equally.

First, the map file generator 34 disposed in the web operating system C2 30 loads the DTD file 26 provided in the open state in the web operating system B3 20 to the web operating system C2 30. The process proceeds (step S1).

Subsequently, the map file generation unit 32 loads the D / B schema from the third D / B 31, and then, with reference to the above-described DTD file 26 and the D / B schema, sets of map files ( 33), the process of generating (step S2).

In the state where such a process is performed in advance, when any program or agent disposed in the web operating system C2 30 or the agent requires the storage of specific XML data, the XML data filter unit 32 performs the web operating system B3 20. It communicates with the 2nd server 22 arrange | positioned at the, and requests this 2nd server 22 to extract the said XML data (step S3).

When such a request event occurs, the second server 22 proceeds to an arbitrary process, for example, searching for the second D / B 21 to extract the XML data requested by the XML data filter unit 32. The XML data is then returned to the XML data filter unit 32. Of course, even in this case, the XML data may not necessarily be extracted from the previous second D / B 21.

In this state, the XML data filter unit 32 determines whether the XML data requested by the second server 22 has been completely received (step S4).

At this time, if it is determined that the XML data requested by the second server 22 has not been completely received yet, the XML data filter unit 32 proceeds to step S5 to maintain a series of standby states.

However, when it is determined that the XML data requested by the second server 22 is completely received, the XML data filter unit 32 uses the aforementioned DTD file 26, map file 33, or the like. After analyzing the XML data, it is determined whether the XML data is in a normal state without any damage (steps S6 and S7).

At this time, when the XML data is transmitted from the second server 22, for example, when it is determined that a series of damage is received due to adverse effects such as a network problem or a server problem, the XML data filter unit 32 flows. Proceed to step S3 described above, so that the aforementioned XML data transmission process can be repeated once again.

However, in the case where it is determined that the XML data is not adversely affected during the transmission of the XML data from the second server 22 and is not particularly damaged, the XML data filter unit 32 sends the previous map file generation unit 34 to the preceding map file generation unit 34. The process of filtering the XML data on the basis of the map file 33 generated by (step S8).

When the filtering process is completed, the XML data filter unit 32 stores the filtered XML data in, for example, the third D / B 31, so that the web operating system C2 may finally retrieve the XML data of the web operating system B3. Ensure stable acquisition.

On the other hand, in accordance with another aspect of the present invention, assuming that the relationship between the web operating system is "limited to the relationship of the web operating system A (10) and the web operating system B3 (20)", as shown in FIG. As described above, the web operating system A 10 may be defined as a source-side system that notifies other systems of update information of its own XML data, and the web operating system B3 20 may be defined as the web operating system A 10. According to the notification, it may be defined as a target side system for updating its own D / B, for example, XML data previously stored in the second D / B 21.

At this time, the first system search unit 14 disposed in the web operating system A 10 may, for example, be notified when the "XML data stored in the first D / B 11" is updated. Batch search the target systems of the selected among them, and serves to select a specific target system, according to the action of the first system search unit 14, if the web operating system other than the web operating system B3 (20) For example, when "Web operating system B1, Web operating system B2 .... Web operating system Bn" and the like are selected as "a target system to be notified when XML data is updated", the web operating system A 10 They can also form a series of "target-source relationships".

In comparison, assuming that the relationship between the web operating systems is "limited to the relationship of the web operating system B3 20 and the web operating system C2 30", the web operating system B3 20 may have It may be defined as a source-side system that notifies the other system of the update information of the XML data, the web operating system C2 (30), according to the notification of the web operating system B3 (20), its D / B, for example, the third It can be defined as a target system for updating the XML data previously stored in the D / B (31).

In this case, the second system search unit 27 disposed in the web operating system B3 20 may notify the user when the XML data stored in the second D / B 21 is updated. It searches collectively the types of target systems and selects a specific target system among them. According to the action of the second system search unit 27, if the web operating system C2 (30) other than the web operation When the system, for example, "Web operating system C1, Web operating system C3 .... Web operating system Cn" and the like is selected as "a target system to be notified when XML data is updated", the web operating system B3 20 Can also form a series of "target-source relationships" with them.

In other words, each web operating system of this type according to another aspect of the present invention may act as a source side system and also as a target side system, depending on the situation as described above.

Hereinafter, a method of exchanging data, for example, a data synchronization method between heterogeneous web operating systems based on an Internet environment according to another aspect of the present invention will be described in detail.

First, another aspect of the present invention will be described under the premise that "Web operating system A 10 acts as a source side system and web operating system B3 20 acts as a target side system".

In this case, as illustrated in FIG. 5, the map file generation unit 25 disposed in the web operating system B3 20 may web the DTD file 13 provided in the open state in the web operating system A 10. The process of loading to the operating system B3 (20) side proceeds (step S11).

Subsequently, the map file generation unit 25 loads the D / B schema from the second D / B 21, and then, with reference to the DTD file 13 and the D / B schema described above, sets of map files ( 24) proceeds to create (step S12).

In the state where the above-described process has been performed in advance, the first server 12 disposed in the web operating system A 10 may, for example, observe the first D / B 11 from time to time, for example, to the first D / B 11. The change of the stored XML data is confirmed, and through this, it is determined whether or not a series of "XML data update events" has occurred (step S13).

At this time, when it is determined that no change has occurred in the XML data stored in the first D / B 11 and a series of XML data update events are not generated, the first server 12 proceeds to the flow at step S14. To maintain a series of standby states.

However, when a series of changes occur in the XML data stored in the first D / B 11 and a separate XML data update event is determined to occur, the first server 12 reflects the change of the XML data. A series of "XML data update information" is produced | generated, and this XML data update information is sent to the 1st system search part 14 (step S15).

In this state, the first system search unit collectively searches for " target system to be notified of whether or not to update XML data " by utilizing its own register information, and selects a specific target system from among them (step S16).

At this time, when the web operating system B3 20 is determined as the "target system to be notified of the update of the XML data," the first system search unit 14 immediately, the XML data delivered from the first server 12 The update information is quickly transmitted to the XML filter unit 23 disposed in the web operating system B3 20.

In this state, the XML data filter unit 23 determines whether or not the series of XML data update information has been transmitted from the first system search unit 14 (step S17).

At this time, when the XML data update information has not been completely transmitted from the first system search unit 14 yet, the XML data filter unit 23 proceeds to the flow at step S18 to maintain a series of standby states.

However, when it is determined that the XML data update information is completely transmitted from the first system search unit 14, the XML data filter unit 23 uses the aforementioned DTD file 13, map file 24, and the like. After analyzing the XML data update information, it is determined whether or not the XML data update information is maintained in a normal state without any damage (steps S19 and S20).

At this time, when the XML data update information is transmitted from the first system search unit 14, for example, when it is determined that a series of damage is received due to adverse effects such as a problem on the network, a problem on the server, and the like, the XML data filter unit ( 23) requests the first server 12 to resend "XML data update information".

However, when the XML data update information is not adversely affected while the XML data update information is transmitted from the first system retrieval unit 14, and it is determined that the transmission of the XML data update information which has been completed is not particularly damaged, the XML data filter unit 23 In step S21, the XML data update information is filtered based on the map file 24 generated by the map file generation unit 25 (step S21).

When the filtering process is completed, the XML data filter unit 23 updates, for example, XML data previously stored in the second D / B 21 based on the filtered XML data update information. The web operating system B3 20 may be synchronized with the change situation of the web operating system A 10.

Next, another aspect of the present invention will be described under the premise that "Web operating system B3 acts as a source side system and Web operating system C2 acts as a target side system". Of course, even in this case, the flow shown in FIG. 5 applies equally.

In this case, the map file generation unit 34 disposed in the web operating system C2 30 loads the DTD file 26 provided in the open state in the web operating system B3 20 to the web operating system C2 30. The process proceeds (step S11).

Subsequently, the map file generation unit 34 loads the D / B schema from the third D / B 31, and then, with reference to the above-described DTD file 26 and the D / B schema, a series of map files ( 33), the process of generating (step S12).

In the state where the above-described process has been performed in advance, the second server 22 disposed in the web operating system B3 20 may, for example, observe the second D / B 21 at any time, thereby providing the second D / B 21 with the second D / B 21. The change of the pre-stored XML data is checked, and through this, it is determined whether or not a series of "XML data update events" has occurred (step S13).

At this time, when it is determined that no change has occurred in the XML data stored in the second D / B 21 and a series of XML data update events are not generated, the second server 22 proceeds to the flow at step S14. To maintain a series of standby states.

However, when a series of changes occur in the XML data stored in the second D / B 21 and it is determined that a separate XML data update event occurs, the second server 22 reflects the change of the XML data. A series of "XML data update information" is produced | generated, and this XML data update information is sent to the 2nd system search part 27 (step S15).

In this state, the second system retrieval unit utilizes its register information to collectively search for the target system to be notified of the update of the XML data, and selects a specific target system among them (step S16).

At this time, when the web operating system C2 30 is determined as the "target system to be notified of the update of the XML data," the second system search unit 27 immediately, the XML data delivered from the second server 22 The update information is quickly transmitted to the XML filter unit 32 disposed in the web operating system C2 30.

In this state, the XML data filter unit 32 determines whether or not the series of XML data update information has been completely transmitted from the second system search unit 27 (step S17).

At this time, when the XML data update information has not yet been completely transmitted from the second system search unit 27, the XML data filter unit 32 proceeds to the flow at step S18 to maintain a series of standby states.

However, when it is determined that the XML data update information has been completely transmitted from the second system search unit 27, the XML data filter unit 32 uses the aforementioned DTD file 26, map file 33, and the like. After analyzing the XML data update information, it is determined whether or not the XML data update information is maintained in a normal state without any damage (steps S19 and S20).

At this time, when the XML data update information is transmitted from the second system search unit 27, for example, when it is determined that a series of damage is received due to adverse effects such as a problem on the network, a problem on the server, the XML data filter unit ( 32 requests retransmission of "XML data update information" to the second server 22.

However, when XML data update information is transmitted from the second system retrieval unit 27 and is not adversely affected, and it is determined that the XML data update information which has been transmitted is not particularly damaged, the XML data filter unit 32 In step S21, the XML data update information is filtered based on the map file 33 generated by the map file generation unit 34 (step S21).

When the filtering process is completed, the XML data filter unit 32 updates, for example, XML data previously stored in the third D / B 31 based on the filtered XML data update information. The web operating system C2 can be synchronized with the changing situation of the web operating system B3.

As described above, in the data exchange method between the heterogeneous web operating systems based on the Internet environment according to the present invention, the exchange data format between the web operating systems designed with this model is unified with XML data, By providing a set of "framework" dedicated to the exchange of XML data to some of the systems, each web operating system designed with this model will be able to achieve "the data exchange that is needed for them" more optimally. To be provided.

When each of these items is realized in the technical background, each web operating system of this type can smoothly proceed a series of XML data acquisition process and XML data synchronization process. Without having to make a big deal in the organizational system, each person can easily exchange necessary information, and eventually, Internet users can easily obtain the effect of maximizing their convenience.

The present invention is not limited to a web operating system having a specific data structure, and has an overall useful effect in a web operating system having various data structures.
