Description

Distributed transaction system having automatic geneation part for interface and method therefor}

The present invention relates to a system for distributing data and a method thereof, and more particularly, to a federated communication interface by referring to a simulation object model (SOM) in the form of an XML document based on a federated object model (FOM). The present invention relates to a data distribution processing system having an automatically generated interface automatic generation unit and a method thereof.

In general, the distributed processing of data refers to a process of combining individual simulations developed for different purposes in different organizations into one large simulation, which is used to generate a simulation network, transmit and receive data, and time for such distributed processing. In order to perform simulation services such as management, HLA (High Level Architecture), a standard technology, is established and utilized.

The HLA-based simulation is federation, a large simulation unit, a federation executive process (also called FedEx), which acts as a server within the federation, and the server. It is composed of federation that is subscribed to and plays the role of client.

Such an HLA consists of HLA Rules, an Object Model Template, and an Interface Specification.

Here, the HLA rules describe the principles and configurations to be followed in order to achieve appropriate interactions between each federation.

In addition, the object model template describes a common method for recording federation model information and a format of a main model. Specifically, the federation object model (FOM) and simulation object model (Simulation) are described. Object Model (SOM) and Management Object Model (MOM) are provided.

The federation object model (FOM) has one FOM per federation and describes information (objects, interactions, etc.) that are commonly used for all federations in the federation.

The simulation object model (SOM) has one SOM per federation and describes the operations and externally available objects and interactions within the federation.

The Management Object Model (MOM) describes a method of identifying objects and interactions used in federation management.

In addition, the interface specification defines the contents of the service of the RTI (Run Time Infrastructure) based on the HLA, and creates and deletes a federation management (FM) (simulation), which is a service required to support a simulation conforming to the high level architecture (HLA) standard. , Synchronization, etc.), Declaration Management (DM) (Transmission and Receipt Information Declaration Service), Object Management (OM) (Transmission and Receipt Service of Information), Ownership Management (OWM) (Take ownership and transfer of information), Time Management (TM) ( It supports six management services: time management related to simulation progress and Data Distribution Management (DDM).

FIG. 1 is a diagram illustrating a conventional data distribution processing system based on the above-described HLA / RTI, and shows a state in which federations establish an interface in order to perform a simulation in a federation.

As shown, each Federate is interworked through the HLA / RTI based network 100, each federation communicates with a federation process (FedEx) that acts as a server of the federation.

The communication between the FedEx and each Federate is to send data to the FedEx to the HLA / RTI-based network 100, each Federate is published / subscribe to receive data sent to the network 100 (Publish / Subscribe) The simulation network manager (10, 11, 12) of each federation is configured in HLA / RTI based on the federation object model (FOM). Implement the interfaces 20, 21, 22 to communicate with the network.

However, as shown, as the size of each federation (Federate) increases, the communication interface for each Federate also increases, it is impossible to reuse or compatible interfaces between the Federate because the interfaces of each Federate are different .

In addition, when the FOM is changed in the entire simulation, each Federate has to modify the Federate's interface according to the changed FOM, and in the process, the developers who code the interface have to redo the interface at the code level. In addition, there is a problem in that a waste of development resources is wasted in terms of time and cost since the work that needs to be compiled and linked for debugging of the modified interface must be repeatedly performed.

The present invention was devised to solve the above-mentioned conventional problems, by automatically generating the interface of each federation to prevent waste of development resources required to implement the interface, thereby improving convenience and reliability in simulation construction. SUMMARY OF THE INVENTION There is a technical problem of the present invention to provide a data distribution processing system and a method having an automatic interface generation.

In order to achieve the above technical problem, a data distributed processing system having an interface automatic generation unit and a method thereof are constructed based on a federation object model (FOM), and a simulation is performed using a markup language. And an interface auto-generation unit for automatically generating an interface by interpreting an object model (SOM) document.

According to the present invention having the above configuration, since the interface is generated by the automatic generation unit which automatically generates the interface, the automatic generation unit required for the interface interworking has the advantage that it can be commonly reused by the respective federations.

In addition, since the interface is automatically generated, the unit test process such as debugging and compiling for interworking is simplified and debugging is easy.

In addition, since the developer only needs to implement the SOM in the XML language in order to implement the interface, there is an effect of reducing developmental defects that may occur in the process of rewriting the code as in the prior art.

In addition, when the FOM changes, only the modified XML document needs to be modified, so that the federation can quickly react to the simulation changes.

In addition, even if a new federation is added, since only an XML document can be created to generate an interface, it is a very advanced invention that can reduce the overall development cost for building an interworking network.

EMBODIMENT OF THE INVENTION Hereinafter, based on an accompanying drawing, the data distribution processing system and its method which have the interface automatic generation part of this invention are demonstrated in detail.

However, the disclosed drawings are provided as examples to sufficiently convey the spirit of the present invention to those skilled in the art. Accordingly, the invention is not limited to the drawings presented below, but may be embodied in other aspects.

In addition, unless there is another definition in terms used in the present specification, it has the meaning commonly understood by those of ordinary skill in the art to which the present invention belongs, and the gist of the present invention in the following description and the accompanying drawings. Detailed descriptions of well-known functions and configurations that may be unnecessarily blurred are omitted.

2 is a block diagram of a data distribution processing system having an interface automatic generation unit of the present invention. The same parts as those in FIG. 1 described above will be described using the same reference numerals.

Like the conventional system of FIG. 1 described above, respective federations of the data distribution processing system of the present invention are linked through the HLA / RTI-based network 100, and each federation serves as a server of federation. Communicate with the federation execution process (FedEx).

In addition, the communication between the FedEx and each Federate is a Publish / Subscribe method in which each Federate receives the corresponding data on the network 100, if the FedEx sends the data to communicate to the HLA / RTI-based network (100) Hereinafter, referred to as a 'PS method'.

At this time, the distributed processing system of the present invention includes an interface automatic generation unit 30 to generate an interface for such PS system communication.

That is, in the related art, the simulation network managers 10, 11, and 12 of the respective Federate implement the HLA / RTI based interfaces 20, 21, and 22 with reference to the federation object model (FOM). The interface automatic generation unit 30 is a configuration that automatically generates the interface (20, 21, 22) of each feather.

Specifically, the simulation network managers 10, 11, and 12 generate a simulation object model (SOM) made of a markup language based on a federation object model (FOM), and generate the interface automatic generation unit ( 30) implements the interface by analyzing the simulation object model (SOM) and automatically generating the code necessary for communication.

That is, the interface automatic generation unit 30 performs a function of generating an interface of each federation while being commonly used by each federation.

Preferably, the markup language used when the network manager 10, 11, 12 generates the SOM based on the FOM is XML (eXtensible Markup Language).

The XML language is capable of user-defined tags and has an advantage of structuring and transmitting data, and thus is suitable as a writing language of the SOM of the present invention.

3 is a diagram showing an XML document structure of the data distribution processing system of the present invention.

Since the HLA / RTI-based simulation implements federation interactions through the federation object model (FOM), in the past, the developer had to write the code for implementing the interface for each federation by referring to the FOM. The present invention only needs to create an XML document for implementing the interface based on the FOM.

In more detail with reference to the drawings, the FOM of the embodiment of the present invention written in an XML document describes the information of the object class (Interaction class), Interaction class (Attributes) and Parameters (Parameters) In the related art, the developer has to code the code for implementing the interface by referring to the FOM.

Description of the lower left of the figure is an example of code for implementing a conventional interface, as described,

"......(syncopation)......

publishObjectClass (ObjectClass, Attributes),

subscibeObjectClass (ObjectClass, Attributes),

publishInteractionClass (InteractionClass),

subscribeInteractionClass (InteractionClass)

...... (hereafter omitted) ...... "

The interface implementation code, etc. had to be written.

However, the present invention focuses on approaching this interface creation problem in the form of XML rather than code, and when a user implements an interface of individual federations as shown in the lower right of the drawing, the developer can simulate the federation simulation object model. (SOM) is written in a document format using the XML language, and the interface automatic generation unit 30 interprets the created SOM to automatically generate code for the interface.

In this case, the SOM document of the embodiment of the present invention prepared by the developer describes information of an object (object) layer, an interaction layer, attributes, and parameters of the FOM. The interface automatic generation unit 30 of the federation interprets the SOM to obtain meta information from the FOM to generate codes necessary for communication to implement the interface.

Therefore, since the interface automatic generation unit 30 can be reused in common by respective federations, the implementation time of code generation for the interface is reduced, and unit tests such as debugging and compiling for interface interworking are performed. The process can be simplified.

In addition, when a new federation is added, the developer only needs to implement SOM in a document format using the XML language, so that the developer does not necessarily have a high level of code programming capability.

In addition, when the interface needs to be modified due to the change of the FOM, the interface can be easily modified by simply changing the XML file of the SOM.

4 is a block diagram of an interface automatic generation unit of the data distribution processing system of the present invention.

The interface automatic generation unit 30 of the present invention interprets the SOM generated by the network manager 10, 11, and 12 in the form of an XML document with reference to the FOM, and generates the meta from the FOM based on the analysis result. It includes a SOM parser (31) to take information and deliver it to the interface generation module (32).

In detail, the interface generation module 32 includes an object generator 321 for generating object information of an interface and an interaction generator 322 for generating interaction information of an interface. (Interaction factory), an attribute generator (323) for generating attribute information of an interface, and a parameter generator (324) (Parameter Factory) for generating parameter information of an interface.

That is, as shown in FIG. 3, if the SOM document describes the information of the object class, the interaction class, the attributes, and the parameters of the corresponding federation in detail, The SOM analysis module 31 interprets the SOM document to grasp the object layer information, the interaction layer information, the attribute information and the parameter information of the corresponding federation, and the information of the corresponding SOM from the FOM based on the information thus obtained. The meta information corresponding to the meta information is loaded, and each generator of the interface generation module 32 automatically generates an interface of the corresponding federation based on the loaded meta information.

Next, with reference to Figs. 5 and 6 will be described in detail a data distribution processing method having an interface automatic generation unit of the present invention.

Similar to the above-described distributed processing system of the present invention, the data distribution processing method of the present invention, each federation (Federate) is linked through the HLA / RTI-based network, each federation acts as a server of the federation (Federation) Communication with the federation process (FedEx), and the communication between the FedEx and each of the Federate sends the data to the FedEx to communicate to the HLA / RTI-based network, each Federate receives the corresponding data on the network Publish / It is assumed that it is implemented by Subscribe method.

The distributed processing method of the present invention is a method for automatically generating an interface for such PS system communication. This will be described in more detail as follows.

First, the federation simulation network manager generates a simulation object model (SOM) document in a markup language based on the federation object model (FOM) (step S 100).

The interface automatic generation unit analyzes the simulation object model (SOM) generated by the simulation network manager of the federation (step S 110).

Subsequently, the interface automatic generation unit automatically generates an interface of the corresponding federation according to the analyzed SOM (step S 120).

Preferably, the markup language used when the network manager generates the SOM based on the FOM is eXtensible Markup Language (XML).

At this time, the step S 120 includes the step as shown in FIG. That is, the interface automatic generation unit obtains meta information from the FOM according to the analysis result of the SOM analyzed by the network manager, and transfers the meta information to the interface generation module (step S 200).

The interface generation module stores the transferred meta information and generates a code for an interface of each federation according to the stored meta information (step S 210).

The interface generating module generates an object factory for generating object (object) information of an interface, an interaction factory for generating interaction information of an interface, and generates attribute information of an interface. It includes an attribute factory (Attribute Factory), and a parameter generator (Parameter Factory) for generating parameter information of the interface.

Therefore, as shown in FIG. 3, if the information of the object class, interaction class, attributes, and parameters of the corresponding federation is specifically described in the SOM document, The interface generating module reads meta information corresponding to the information of the corresponding SOM from the FOM based on the information found by interpreting the SOM document, and by each of the generators of the interface generating module based on the retrieved meta information. The federated interface will be created automatically.
