Accompanying drawing explanation
Fig. 1 is that the privately owned model of application system provided by the invention is to CIM Model Mapping organization chart.
Fig. 2 is data pattern file flow path switch figure provided by the invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
The present invention adopts common information model as the normal data model of inter-system data exchange, from the private data model XML file of application system, parse information data, according to mapping ruler, be converted to the model data file that meets CIM semanteme and syntactic structure.The present invention is based on a kind of mapped system that this adopts, its structural drawing as shown in Figure 1, main include file parsing module, map unit and data model storage unit, wherein document analysis module is for realizing the extraction of file data information; Map unit allows user according to self system different application and allocation models mapping ruler realize the conversion between system private data model and common information model by mapping ruler; Data model storage unit is mainly used in storing, manages, safeguards common model information.Concrete:
(1) document analysis module
Document analysis module is the source of whole mapping method input message, completes parsing and the extraction of application system information, for mapping ruler provides converting objects.Document analysis module is resolved the XML file importing into, for improving the analyzing efficiency of large file, the comprehensive feature of analyzing existing XML document parser, adopt DOM(Document Object Mode) with SAX(Simple API for XML) the mutually nested mode of resolver extracts data message, SAX is positioned at analytical algorithm skin, data message for all appointments of sequential search XML file, triggers corresponding DTS; DOM is positioned at analytical algorithm internal layer, for data item corresponding to certain specify labels of stochastic searching, obtains data message and carries out stores processor.
(2) map unit
Map unit is the core of whole conversion method, completes the privately owned model of application system to the mutual conversion of CIM model, it provide mapping ruler configuration, read, store and the function such as parsing.Map unit comprises mapping ruler storehouse, configuration tool and modular converter.Wherein configuration tool is mainly set up model mapping rule, formation model mapping rule file to configuration between privately owned model and CIM model; Modular converter is realized privately owned model data information that document analysis module parses goes out and the mutual conversion of CIM database information in conjunction with mapping ruler; Mapping ruler storehouse is used for storing user configured map information and the attended operations such as inquiry, modification is provided.
Map unit, as realizing the chief component unit shining upon between privately owned model and CIM model, is set up model mapping rule file, and the step of its foundation mainly comprises: 1. set up the whole network CIM model bank; 2. according to application system demand, delete irrelevant model, reduce model redundancy, CIM model is minimized; 3. in configuration tool, import application system model file and CIM model file, configuration mapping ruler, realizes the mapping between application system model and CIM model.Map unit receives document analysis information, by query mappings rule base, obtains pre-configured model mapping rule, and modular converter is converted to the model information of appointment the CIM model information of standard and imports CIM model repository according to mapping ruler.Wherein configuration tool shows application system model information and CIM model information with tree structure respectively, user can adopt the manual mode pulling to set up the mapping ruler between the privately owned model of described application system and CIM model according to the corresponding relation between model information, and the map information of formation imports mapping ruler library storage.
(3) data model storage unit
The storage that data model memory module comprises model, manage, browse, import, the function such as derivation, its nucleus module be one for storing the CIM relevant database of common model information.
Data model storage unit the supply a model importing of description document, the operations such as derivation, data management and maintenance of CIM/XML file, wherein the importing of model description file carries out dissection process by the corresponding data inserting of the model data obtaining storehouse to model description file; The derivation of CIM/XML file be one according to all data messages in CIM data model structure ergodic data storehouse, be assembled into CIM object and be given to " XML generator program ", the process that the CIM/XML instance document of generation standard is called for associated component/service, has realized from CIM relational database extracted data and has generated master pattern file; Browse unit provides browsing of CIM model and retouching operation, and in browser interface, user not only can check model information, can also modify to model information, the attended operation such as renewal.
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing and specific implementation method, the present invention is described in further detail.
Fig. 1 be the privately owned model of application system to CIM Model Mapping organization chart, shown the main modular unit that Model Mapping method comprises, comprise document analysis module and map unit, data model storage unit etc.User can be in map unit corresponding relation by browsing, between inquiring user data model and CIM model, adopt to pull, select or the mode such as manual typing is set up the mapping ruler of two kinds of models, formation model mapping rule file; Document analysis module reads, verification and parsing are obtained model data from the model file of application system; Map unit stress model mapping rule file is also converted to CIM model data by mapping algorithm program by model data and deposits in CIM database; Adopt the data message in the file export function traversal CIM relational database of data model storage unit, according to the CIM/XML instance document of resource description framework file generated standard for associated component/service call.
The privately owned model of application system that the present invention provides according to said system and the mapping method of CIM model, process flow diagram as shown in Figure 2, specific implementation method is: in the configuration tool of map unit, import described application system model file and CIM model file, in configuration interface, will demonstrate application system model and CIM model with tree structure, user can set up the mapping relations between the privately owned model of described application system and CIM model; Simultaneously in document analysis module, described privately owned model file from application system database reads first verification its whether meet its corresponding XML Schema standard, if meet verification, utilize analytical algorithm to extract described private data model file information data, otherwise to the error message of application system back-checking; The information data of obtaining is before modular converter shines upon storage, mapping ruler storehouse need to judge whether to have loaded mapping ruler, if load, modular converter is converted to the information data of obtaining one by one CIM model data and deposits in CIM relational database table according to mapping ruler, otherwise return to information, requires to reload mapping ruler.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although the present invention is had been described in detail with reference to above-described embodiment, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement the specific embodiment of the present invention, and do not depart from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of claim scope of the present invention.
