Description

[0001] The present invention relates to a method for interworking data between heterogeneous systems using service patterning,

The present invention relates to a data interworking method between heterogeneous systems, and more particularly, to a method of interworking data between heterogeneous systems using service patterning.

As business systems evolve, data interworking between heterogeneous systems is often required. For example, when a developer first develops an interworking interface for system interworking, the interworking interface may be modified or customized by reflecting various requirements according to the change of the business of the enterprise. (customize) the process.

However, in reality, it is not easy for the developer to develop the interface itself. The functions required for interworking data are not completed by simple configuration, but skilled developers can implement complex data convolution functions, implement complex script functions that only developers can use, or create complex rules This is because system interworking is possible only if the service to be processed is used.

Furthermore, it is very difficult to add or modify minor functionality to the interoperability interface developed. It takes a lot of time and effort as well as the skill of the developer because it needs to build a function or service to be changed, and then go through a series of processes after a desert. In addition, for function addition or modification, it is necessary to analyze the interlocking process of the interlocking interface one by one to understand the entire function and to check which service is connected. Therefore, it takes a long time to develop the interworking interface, and the project cost also increases.

It is practically impossible for a novice developer to put in a system interworking project. This is because it requires a lot of training time to understand the scripting language for system interworking and develop external service interworking. In addition, since the difference in functions produced according to the developer's programming skill is so great, it is difficult to provide a uniform quality system interworking service.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a data interworking method between heterogeneous systems using service patterning.

The problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

According to another aspect of the present invention, there is provided a data interworking method for heterogeneous systems, the data interworking apparatus for interworking data between a source system and a target system using service patterning, the data processing apparatus comprising: And defining a plurality of upper patterns as a plurality of lower patterns belonging to each upper pattern, wherein the upper pattern is a data extraction pattern, a data conversion pattern, and data A stack pattern); Defining a function for the sub pattern as a method concept; Extracting data from the source system by executing the data extraction pattern and a subpattern attributed thereto; Executing the data conversion pattern and a subpattern attributed thereto to convert the extracted data to be interlocked with the target system; And loading the converted data into the target system by executing the data loading pattern and its subordinate patterns.

The data can be interlocked by executing the sub pattern sequentially with reference to the function of the sub pattern without performing a separate coding operation.

The subpattern includes a condition pattern for comparing and determining data, an execution pattern for executing an API defined in the system, a loop pattern for repeatedly processing data, and an external service execution pattern for calling an API defined in the external system can do.

The item of the method may include a processing order of the lower pattern, whether or not to execute the processing, a processing type, and an object to be processed.

The details of other embodiments are included in the detailed description and drawings.

As described above, according to the data interworking method between heterogeneous systems according to the present invention, it is possible to easily use complex functions generated in the interlocking process by patterning repetitive functions. Therefore, it can quickly reflect the requirements of business changes. In addition, a general user (for example, a consultant, an administrator) other than a developer can implement a complex function for system interlocking conveniently with a simple pattern setting defined beforehand even if coding is not performed separately.

In addition, according to the present invention, development productivity can be improved by reducing the load given to a developer by patterning and reusing functions repeatedly used, and the project period and cost for development can be significantly reduced. Also, since it does not involve any coding work, it is possible to modify the data interworking operation in real time even if it is not a developer.

Compared with the scripting method or the web service method, which is directly developed by a developer through a coding process, the data interworking method of the present invention minimizes errors in interworking since it uses a very well defined pattern.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

1 is a block diagram conceptually illustrating data interworking between heterogeneous systems according to an embodiment of the present invention.

The system A or the source system 10 may have various databases in managing data processing and resources for performing predetermined tasks. In addition, the source system 10 may further comprise means for managing, processing and transmitting / receiving data, means for processing communications with external devices or external systems, and means for authentication and security, This may include various hardware devices, server devices, and software. In this embodiment, the source system 10 serves to provide data necessary for data interworking. The data of the source system 10 is stored in the database by the source data schema, which refers to the structure (object, attribute, relationship) and constraints of the database of the source system 10. Here, an entity is an object in the real world, which refers to a type or an intangible information that exists and can be distinguished from each other. An attribute describes the characteristic or state of an entity, and refers to the smallest unit of data. Describe the association between the above individuals.

Like the source system 10, the system B or the target system 20 can have various databases in managing data processing and resources for performing predetermined tasks. In addition, the target system 20 may further include means for managing, processing, transmitting and receiving data, means for processing communication with an external device or external system, and means for authentication and security, This may include various hardware devices, server devices, and software. In this embodiment, the target system 20 is an object of system interworking with the source system 10. The data of the target system 20 is stored in the database by the target data schema. Therefore, the source data stored according to the source data schema is converted into the data format corresponding to the target data schema through the data interlocking process of the present invention.

In this manner, the data processing apparatus 30 is to link the data of the source system 10 with the data of the target system 20. [ The data processing apparatus 30 may have various databases in data processing and resource management for performing system interworking or data interworking operations. In addition, the data processing apparatus 30 may further include means for managing and processing data, transmitting and receiving data, means for processing communication with an external device or an external system, and means for authentication and security , Which may include various hardware devices, server devices, and software.

2 is a flowchart showing a method of interworking data between heterogeneous systems by a data processing apparatus according to an embodiment of the present invention.

First, the data processing apparatus 30 defines a system interworking pattern (100). Specifically, services for system interworking or data interworking are grouped into tasks and defined as a pattern. One pattern is a separate and independent module for performing a plurality of tasks through a series of processes. Lt; / RTI > In the work layer, the work module describes and defines the characteristics of the application service for interworking data, and gives responsibility for the construction and operation of the service module by transmitting the work data to the service module. In the service layer, a service module provides service data for executing related devices to perform a target operation by the user. The service module may correspond to an interworking library (e.g., API library) for executing processing instructions for at least one specific interworking function.

FIG. 3 is a diagram illustrating a table in which a pattern and a function are meta-structured according to an embodiment of the present invention. Meta information required for meta-structuring may include an upper pattern, a lower pattern, functions 1 to N (N is a natural number), and the like.

The upper pattern is defined to define the overall process of data interworking. For example, the upper pattern may be composed of a data extraction pattern, a data conversion pattern, and a data loading pattern.

The subpatterns are attributed to the upper pattern and represent concrete execution tasks. Here, the subpattern includes a condition pattern for comparing and judging data, an execution pattern for executing an API defined in the system, a loop pattern for repeatedly processing data, an external service for calling an API defined in the external system An execution pattern, and the like. Each upper pattern can be defined by such a lower pattern.

The function may be defined by a concept of a method. Items of a method may include a processing order of a subpattern, whether or not the subpattern is executed, a processing type, and a processing object. Here, the processing order indicates a sequence of patterns to be executed sequentially, whether or not to execute the function of the pattern indicates a processing type value obtained by patterning the functions of the pattern, As an object that can be processed, source data or target data can be exemplified.

Referring again to FIG. 2, the user selects a pattern (110) necessary for interworking with the system using the pattern table that has been previously meta-structured. The upper pattern must be selected for interworking with the system and the lower pattern assigned to each upper pattern can be individually selected according to the attributes of the source system 10 and the target system 20. [

Subsequently, the function is defined for each selected sub pattern (120). As mentioned above, the functions such as the processing order, execution status, processing type, and processing object are defined for each subpattern.

Based on the patterns and functions thus defined, the data interlocking operation is executed (130). According to the system interworking method of the present invention, a sub-pattern is sequentially executed with reference to the function of a sub-pattern without performing a separate coding operation, so that an ordinary user can easily complete a data interworking operation regardless of the programming level.

The execution of the data interlocking operation of the present invention will be described in detail with reference to FIG. FIG. 4 conceptually illustrates the execution of a data interlocking operation according to an embodiment of the present invention.

When a pattern and a function for system interlocking are defined through steps 100 to 120 of FIG. 2, a data extraction pattern and a subpattern attributed thereto (for example, an execution pattern) are executed to extract data from the source system 10 (200).

Subsequently, the data conversion pattern and the subpatterns (for example, the first condition pattern, the second condition pattern, the execution pattern, and the loop pattern) belonging to the data conversion pattern are executed to convert the extracted data to be interlocked with the target system 20 (210).

Finally, the data loading pattern and its subordinate patterns (e.g., condition patterns, execution patterns) are executed and the converted data is loaded on the target system 20 (220). By realizing the system interlocking using the patterned service, the source data stored in accordance with the source data schema 230 is converted into the data format corresponding to the target data schema 240, and the system interworking is completed.

The data interworking method between heterogeneous systems of the data processing apparatus according to an embodiment of the present invention may be implemented in the form of program instructions that can be executed through various computer means and recorded on a computer readable recording medium. The computer-readable recording medium may include a program command, a data file, a data structure, and the like, alone or in combination. The program instructions recorded on the medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of computer software.

Examples of computer-readable media include magnetic media such as hard disks, floppy disks and magnetic tape; optical media such as CD-ROMs and DVDs; magnetic media such as floppy disks; Magneto-optical media, and hardware devices specifically configured to store and perform program instructions such as ROM, RAM, flash memory, and the like. Examples of program instructions include high-level language code that can be executed by a computer using an interpreter, as well as machine accords such as those produced by a compiler. The hardware devices described above may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.

A computer readable recording medium according to the present invention includes a software module for executing the process as described above. Such a module includes a pattern definition module, a pattern selection module, a function definition module, and an interworking task execution module.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
