Embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Before specifically introducing the data integrating method based on unified data model of the present invention, first simply introduce solid data involved in the present invention, unified data model, entity data object, virtual data object and unified virtual data center.
In enterprise, there are various types of data, such as, about the data, the data about emulation, the data about test etc. of design.For the data of each type, all comprise the data object after multiple concrete instantiation.Such as, data about kind of design just comprise the design data object after multiple concrete instantiation, such as, when designing aircraft wing, there is multiple design proposal, like this, the data object of the design proposal about aircraft wing after multiple concrete instantiation is just comprised about the data of craft wing design type.In the present invention, solid data refers to the general name of the data of certain type, the all data belonging to a kind of particular type are called a kind of solid data, and entity data object is the data after instantiation concrete one by one in solid data, entity data object represents the data after the concrete instantiation of in a solid data one.Such as, the data of user type belong to a kind of solid data, and the data of each particular user are exactly an entity data object, such as, about the user data of user Zhang San be exactly two different entity data object about the user data of user Li Si, and the user data of all users forms user entity data jointly.
Often there are a large amount of data in enterprises, these data are scattered in again in various application system, in such as PDM, TDM, SDM etc.In order to consistance and the integrality of data, solve the supervisor status that data scatter is out of control, in the present invention, build a unified virtual data center on these systems, as in Collaborative Design process, the basis of data sharing and interoperability.To the entity data object be scattered in various application system do not stored in unified virtual data center, but store and each entity data object virtual data object be one to one scattered in various application system.Described virtual data object and each entity data object one_to_one corresponding be scattered in various application system, the mapping being each entity data object in unified virtual data center, by the displaying that is mapped to the displaying of virtual data object and management corresponding entity data object and management.
Data due to enterprise are stored in different external data sources, such as various data management system, database, file etc., even if so make the describing mode of the entity data object in same solid data also may be different, such as, describing mode about each entity data object of user entity data may be just different, such as in financial system, the entity data object of user Zhang San comprises ID, name, department, the contents such as wage, in marketing system, the entity data object of user Zhang San comprises ID, title, department, sales volume, the contents such as task performance, this different describing mode makes the unified management difficulty of data.For the ease of carrying out unified management to the data be stored in different external data sources, we adopt the mode of unified data model to describe the data of same type.Unified data model describes the one of virtual data object, it expresses the information of virtual data object formation and virtual data object structural relation, which define and describe the unification of virtual data object and the form of standard, enterprise has a set of unified data model meeting the data management demand of this enterprise.After being provided with unified data model, enterprise is when defining concrete virtual data object, and the form that will define according to this unified data model carries out, and can not arbitrarily carry out.Such as, after defining the unified data model of craft wing design scheme, for the design proposal that each is concrete, the form that just must define in strict accordance with the unified data model of craft wing design scheme when expressing the virtual data object of this design proposal carries out.Like this, by unified data model, be conducive to consistance that enterprise states virtual data object and standardization, thus be beneficial to the unified management to enterprise data target.
As shown in Figure 1, unified data model generally includes label layer, type layer, version layer, structural sheet and address layer.The mark (ID) of described label layer record virtual data object.The type of described type layer record virtual data object, each unified data model correspond to the data of a type.The version of described version layer record virtual data object, each virtual data object has a unique version number.Structural relation between described structural sheet record virtual data object and other virtual data object, the membership namely between father's data object and subdata object.Such as, the parts of product are made up of multiple part, and like this, parts data object is exactly father's data object, and part data object is exactly subdata object, is exactly structural relation, also claims membership between them; Design department manages multiple designer, and like this, the data object of design department leader is exactly father's data object, and the data object of designer is exactly subdata object, is exactly structural relation, also claims membership between them.Because virtual data object does not preserve concrete data content, but the acquisition approach of entity data object is preserved by virtual data object, when calling concrete entity data object, also call from the external data source storing this entity data object, so the acquisition approach of entity data object corresponding to described address layer record virtual data object.
As shown in Figure 1, unified data model can also comprise remarks layer, the remark information of its record to virtual data object, the virtual data object such as when defined, virtual data object of whose definition etc.Certainly, as required, unified data model can also comprise other layers, such as authority layer, the authority etc. that its record operating personnel have virtual data object.
Fig. 2 is the schematic diagram of the data integrated system based on unified data model according to an embodiment of the invention.As shown in Figure 2, dynamic modeling module is used for the various types of data for enterprise, and data, the data about instrument, the data about design, the data about emulation, the data about test etc. such as about equipment set up a unified data model respectively.By setting up unified data model, all virtual data objects of enterprise can be expressed with form that is unified and standard, thus be convenient to the unified management to virtual data object.Simultaneously owing to having mapping relations one to one between virtual data object and entity data object, thus the unified management to entity data object can be realized.By this dynamic modeling module, enterprise is allowed to meet the unified data model in each stage such as demand, design, emulation, test in the product development process of enterprise practical data management demand, thus be a set of unified data model meeting kernel business system demand of enterprise's structure, because unified data model comprises structural sheet, so this cover unified data model not only comprises the unified data model for describing the various types of virtual data objects involved by enterprise, also comprise the structural relation between each unified data model.
Can with neutrality, there is readable language describe unified data model, such as adopt XML language to describe described unified data model, adopt XML language to describe unified data model and be convenient to User Defined unified data model and be convenient to modify and secondary development to unified data model simultaneously.
In order to improve the efficiency setting up unified data model, as shown in Figure 2, a master pattern storehouse can be provided.Some normal data models are provided when providing data management system for enterprise, and by these normal data model storage in this master pattern storehouse.Enterprise is when setting up a set of unified data model of oneself, the maximally related normal data model with kernel business system demand can be called from this master pattern storehouse, and according to kernel business system demand, these normal data models are modified, comprise the type etc. of some unified data model of amendment, and increase some unified data model etc., thus set up a set of unified data model meeting this kernel business system demand.Such as, the research and development chief inspector of enterprise can according to the needs of this kernel business system, call a suitable normal data model, and set up the design unified data model of enterprise based on this normal data model from master pattern storehouse; The normal data model that another is suitable is called from master pattern storehouse, and based on this normal data model emulation unified data model setting up enterprise etc., a set of unified data model meeting kernel business system demand of final formation.
As shown in Figure 2, the unified data model established is stored in data model libraries, so that unified data model can be called when needing the virtual data object in each stage in employing unified data model definition product development process from data model libraries by enterprise.
As shown in Figure 2, after being provided with unified data model, data pick-up and integration module can call unified data model from data model libraries, and define each concrete virtual data object in each stage in this product development process according to the form of unified data model defined.Such as, when carrying out the aircraft development of certain model, designer can call wing design unified data model from data model libraries, and defines the design virtual data object of the aircraft wing of this model based on this wing design unified data model; Emulation personnel can call wing emulation unified data model from data model libraries, and define the simulation virtual data object etc. of the aircraft wing of this model based on this wing emulation unified data model.This data object Definition Model comprises Model Mapping submodule, object map submodule, object definition submodule and contextual definition submodule.
User, when adopting unified data model to define concrete virtual data object, first sets up the mapping relations between solid data in external data source and unified data model by Model Mapping submodule.Because unified data model comprises type layer, it have recorded the type of the virtual data object defined according to this unified data model, and each external data source, the solid data stored in such as PDM, TDM, SDM etc. also all has type, the type recorded by the type layer and the type of solid data are mapped, and just can set up the mapping relations between solid data and unified data model.After mapping relations between solid data and unified data model establish, define with this solid data included by each entity data object one to one virtual objects time, the form that will define according to this unified data model carries out.
After the mapping relations being established solid data and unified data model by Model Mapping submodule, each entity data object included by this solid data be converted to virtual data object.First mapping relations between entity data object and virtual objects to be set up by object map submodule.Because each entity data object has a unique mark and acquisition approach, object map submodule is by calling unique identification and the acquisition approach of entity data object, and give corresponding virtual data object by this unique identification and acquisition approach, thus the mapping relations set up between virtual data object and entity data object, wherein, the unique identification obtained is mapped in the label layer of virtual data object, and the acquisition approach obtained is mapped in the address layer of virtual data object.After establishing the mapping relations between virtual data object and entity data object, by object definition submodule other attribute according to the form defining virtual data object of unified data model, comprise the version number determining virtual data object, it is deposited in the version layer of virtual data object; About the remark information of virtual data object, it to be deposited in the remarks layer of virtual data object etc.Like this, a virtual data object corresponding with an entity data object has just been defined completely.
After having defined virtual data object, if there is data correlation relation between the virtual data object defined and existing virtual data object, so the data correlation relation between this virtual data object and existing virtual data object will be determined by contextual definition submodule.Described data correlation relation comprises the interact relation between virtual data object; Derived relation; Transformational relation; Mapping relations, the property value transitive relation namely between same class virtual data object; And property value mapping relations, the individual attribute value transmit relation namely between virtual data object.Described interact relation refers to that a virtual data object can have an impact to another virtual data object, when this virtual objects changes, also will change by its virtual data object affected.Such as, at product demand investigate phase, a demand data object may have an impact to another demand data object, thus interact relation is formed between two demand data objects, such as, need this demand data object lightweight can have an impact to needs intensity this demand data object high, therefore form interact relation between them.Described derived relation refers to that a virtual data object is derived from by another virtual data object.Such as, the demand that product demand investigate phase produces finally will be embodied by certain index of product, be exactly derived relation like this between this demand data object and this achievement data object, namely achievement data to as if derived from by demand data object.Described transformational relation refers to that a virtual data object is converted by another virtual data object.Such as, user has found certain problem in product use procedure, thus has just had certain demand, and so this demand data object is converted by this problem data object exactly, and the data relationship between them is exactly transformational relation.Mapping relations between described data object, as previously mentioned, refer to the property value transitive relation between same class virtual data object, that is, the value of all properties of a virtual data object is all by the value transmit of the virtual attribute according to object of another same class number.Such as, a coordinate data object A, it has three attributes, be respectively X-coordinate, Y-coordinate and Z coordinate, another of a sort coordinate data object B, it also has three attributes, be respectively X ' coordinate, Y ' coordinate and Z ' coordinate, wherein the attribute X ' coordinate of coordinate data object B, Y ' coordinate and Z ' sit target value by the value transmit of three attribute X-coordinate of coordinate data object A, Y-coordinate and Z coordinate, and the data relationship so between coordinate data object A and coordinate data object B is exactly mapping relations.Property value mapping relations between described data object, as previously mentioned, refer to the individual attribute value transmit relation between a virtual data object and another virtual data object.Such as, an achievement data object A has multiple attribute, such as ID, title, numerical value, description etc., a supplemental characteristic object B also has multiple attribute, such as ID, title, numerical value, type etc., wherein the value of one of them attribute " numerical value " of supplemental characteristic object B is by the value transmit of one of them attribute " numerical value " of achievement data object A, and the data relationship so between achievement data object A and supplemental characteristic object B is exactly property value mapping relations.Certainly, if there is not data correlation relation between the virtual data object defined and existing virtual data object, just do not need to set up data correlation relation between virtual data object by contextual definition submodule.
As shown in Figure 2, defined virtual data object is stored in unified virtual data center.This is unified virtual data center and is used for storing and all entity data object all virtual data objects one to one of enterprise, to realize the unified store and management to all virtual data objects of enterprise, and then realize the unified management to all entity data object of enterprise.
As shown in Figure 2, data integrated system based on unified data model of the present invention also comprises data display module, it is for showing and managing all virtual data objects, due to virtual data object and entity data object one_to_one corresponding, thus can realize showing and management the unified of all entity data object by the acquisition address of the entity data object of the correspondence in the address layer of virtual data object.Data display module mainly comprises shows view definition submodule, data display and management submodule, data course is shown and management submodule, and data tracking is shown and management submodule, wherein said displaying view definition submodule is for defining the data type needing to show, described data display and management submodule are for showing and managing concrete virtual data object and entity data object, described data course is shown and is managed submodule for showing the data course relation with managing virtual data object and entity data object, described data tracking is shown and is managed submodule for showing the data tracking relation with managing virtual data object and entity data object.
Wherein said displaying view definition submodule by allow user define need show unified data model set, and the unified data model filtered out not in this set and define need show data type.Store in data model libraries and multiple application system, the unified data model that the solid data that such as design system, analogue system, pilot system etc. store is corresponding, relate to variety classes, different majors.If a set of view of these unified data model represents, for checking complexity user and inconvenient.By showing view definition submodule, allowing user to set up different displaying views, the exhibition method of different majors or tissue being provided, user can be facilitated the operation of virtual data object.Definable typical case shows that view comprises: product BOM tree view, its hierarchical structure exhibiting product unified data model formed with " assembly and part "; Simulation analysis view, it shows unified data model etc. with the form of " model-grid-material-load-result ".No matter be the view of which kind of type, be all by transferring relevant unified data model to realize according to the type of unified data model when showing, by showing that different unified data model set realizes the displaying to dissimilar data in the view.
Described data display and management submodule are for showing and managing concrete virtual data object and entity data object.After showing that view definition submodule defines the unified data model set needing to show, by clicking one of them unified data model of showing, just can show all virtual data objects defined according to this unified data model, thus the displaying realized virtual data object and management.Simultaneously, owing to having mapping relations one to one between virtual data object and entity data object, like this, by clicking virtual data object, transfer the acquisition approach of the entity data object corresponding with this virtual data object, just can realize the displaying to corresponding entity data object and management.
There is various incidence relation each other in each entity data object stored in different external data source, and between virtual data object and entity data object, there is one-to-one relationship, by displaying and the management of virtual data object incidence relation each other, displaying and the management of the incidence relation between entity data object can be realized.As described above, owing to defining the data correlation relation between virtual data object, so the virtual data object in unified virtual data center exists various incidence relation each other, can review data according to these incidence relations and analyze.Wherein said data tracking is shown and is managed submodule for showing the tracking relationship between managing virtual data object and between solid data.Following functions can be realized: (1) impact analysis: be mainly used to determine that a virtual data object changes the impact caused by the data tracking relation between virtual data object, namely the change of a virtual data object can have an impact to which virtual data object, the virtual data object acted on is changed from virtual data correspondence, track the bottom, and corresponding adjustment is done to all virtual data objects on link; (2) source analysis: on the contrary with impact analysis, followed the tracks of by the last virtual data object of data correlation relation to a virtual data object, progressively up follow the tracks of, trace into most top layer, and corresponding adjustment is done to all virtual data objects on link, such as, when design effort starts from lower floor's node of product model, as component level demand, structural unit etc., use traceback can determine what the high-rise demand causing these lower floor's nodes is.Owing to having mapping relations one to one between entity data object and virtual data object, by just can realize impact analysis to corresponding entity data object and source analysis to the impact analysis of virtual data object and source analysis.
Described data display module also comprises data course and shows and management submodule, it is for showing the data course relation with managing virtual data object and entity data object, and described data course pass is the data development correlation in evolution in product development process in an iteration cycle and between different iteration cycle.Such as, after certain scheme complete design, and after have passed through the checking of emulation, test, be then called a round of design proposal, a round is exactly an iteration cycle.By data course relation, just can show which change a virtual data object experienced by an iteration cycle, realizes the visual of data variation.After design proposal lives through multiple iteration round, just may form a design phase, the design phase is the milestone that of design is large, after a design phase, design proposal can evaluated and screening, get rid of bad design proposal, and more detailed design effort can be carried out.Can show which change a virtual data object experienced by during the multiple different iteration cycle of a design phase or different design stage by data course relation.Fig. 3 is design iteration round and the schematic diagram of design phase of design proposal in a certain product development process.Wherein, in first stage, the design proposal A of system have passed through the iteration of three rounds, and the design proposal B of system and design proposal C have passed through the iteration of two rounds, and the design proposal AA of subsystem A have passed through the iteration of two rounds.At design proposal A, design proposal B and the design proposal C of system, and after the design proposal AA of subsystem experienced by above-mentioned iteration round, design proposal is assessed and screens, form a design phase, by assessing and screening, the design proposal B of system is rejected, and design proposal A and design proposal C proceeds iteration, and add new design proposal AB for subsystem A and proceed iteration, starting the Iterative Design of subsystem B simultaneously.In subordinate phase, also to carry out taking turns Iterative Design to each design proposal more, and to again assessing design proposal time to a certain degree and screening, thus enter the 3rd design phase etc., until satisfy the demands.By data course relation, after living through subordinate phase, just the entity data object of the design proposal AA finding out system etc. can experienced by which iteration, which change etc.
In addition, described data display module can also comprise unshowned data pedigree management submodule in Fig. 2, and it is for showing and managing the data pedigree in a certain product development process.Data pedigree is the set of the data correlation relation of all virtual data objects in a certain product development process, because virtual data object and entity data object have mapping relations one to one, it is also the set of the data correlation relation of all entity data object in a certain product development process.In data pedigree management submodule, user can revise, increases or delete the data correlation relation between each virtual data object, thus changes data pedigree.
After describing the Data Integration based on unified data model of the present invention in detail, introduce the concrete steps of the data integrating method based on unified data model of the present invention below.
