Embodiment

Below, with reference to accompanying drawing embodiments of the present invention are described.

Before an embodiment of explanation DTU (Data Transfer unit) of the present invention, at first, object range of the present invention and even present position are described referring to figs. 1 through Fig. 4.

Fig. 1 is for illustrating (the Object Management Group: the figure of the object range of MDA (Model DrivenArchitecture) style of formulating, the invention in the schematism standardization body of dispersion object) according to OMG, Fig. 2 for explanation in recent years according to the figure of the model-driven development scheme of using in the MDA software development, Fig. 3 is the graph of a relation of the present position of the explanation object range of MDA and object part of the present invention, and Fig. 4 is the figure of expression basic concept structure of the present invention.

As the MDA schematism, as shown in Figure 1, by computing independent model CIM (ComputationIndependent Model), platform independent model PIM (Platform Independent Model), special transaction module PSM of platform (Platform Specific Model) and real dress (implementation) are formed, and become to this to append the product group of portion of formation platform and the system that expression one cover provides the platform model of service.Though CIM, PIM, PSM pretends to be recorded and narrated for model in fact, in fact by CIM data 1 corresponding to each model, pim data 2, PSM data 3, real dress data 4 show (with reference to Fig. 3, Fig. 4).

So-called platform be say can executive routine condition, the condition project of OS etc. is arranged.

CIM data 1 are equivalent to the professional important document of modeling object, for being independent of the domain model data division that requires the pattern book and the computing of the analysis result of basic design sheets derivation software from customer requirements.This is showed with the vocabulary that the object domain practician knows.

The platform independent model data of pim data 2 about for the platform group's that can correspondence be different from homotype (for example refer to just transacter style, perhaps just supervision/control system style) platform.That is, the design of the upstream CASE by not selecting platform can become possible model data with the software development of the conversion of the requirement of sufficient respective user and technology.

PSM data 3 are the particular type of pim data 2 and platform, for example, and for having made up based on Java with based on the model data of using method such as Web, according to the special transaction module data of platform of carrying out detailed design specific to platform.

Real dress data 4 are the style of all information of being provided for construction systems and shifting to utilization, respectively specific to platform with detailed program language defined.Fig. 2 is the figure of explanation according to the model-driven development scheme of MDA, is an example for the general software development of the MDA that generates the model that is independent of platform.

This model-driven development scheme is, the software developer utilizes model editor (UML editing machine), the information that input is necessary, generate and editor's class figure, sequence chart, state transition diagram etc., because the model editor in this stage and other companies does not have interchangeability, with a kind of label of the specification that is included in MDA with model editor (UML editing machine) the 11 class figure that make, the relation of sequence chart etc. convert to can additional textual information XMI (XMLMetadata Interchange) form, form by XML12 that data are represented with textual form is preserved, for example, and the mutual utilization between the model editor of other companies (UML editing machine) 13 becomes possible form, makes the model that is independent of platform.

UML is the ellipsis of Unifild Modeling Language (unified modeling language), the standard language that uses when recording and narrating model with figure.As the description method of figure, as previously mentioned, defined class figure, sequence chart, state transition diagram etc.So-called model is meant some thing of the action etc. of analysis, abstract structure as business and software, software.XML is the meaning of Extensible Markup Language (extend markup language).Model debugger 14 and the model compiler 15 of making the check of program can generate the program of corresponding platform with XML form handover procedure data by model compiler 15.

Fig. 3 represents the object range of MDA, and the longitudinal axis is represented modeling object, the stage of transverse axis representation model (flow process of processing).As modeling object, except that business, can also exemplify picture, controller, business logic layer (BusinessLogic Tier), the structure of the basic styles design of software, Computer Design environment etc. are determined in the application that database etc. are relevant.As the stage of model, comprise the CIM stage that obtains analysis result, become the PIM stage of the abstract design of common ground, the PSM stage and the installation phase that design in more detail, wherein, as thinking the frame of broken lines part, special according to the improvement part of the possible MDA of OMG style, normalization in the future, the present invention is with the modeling object that is applied as on the business logic layer, and the mesh-like area that strides across from the PIM stage to the PSM stage partly is object range.This business logic layer is based on the consideration that the structure of using is divided into four layers classification, is provided for the layer of processing unit's (business logic) of service operation.

Fig. 4 is the business logic layer represented in Fig. 3, particularly expression is carried out to be not converted to the figure that carries out further specific to the relation of the PSM3 of the optimized detailed design of platform by the PIM2 of the design of the upstream CASE about the difference of platform with this PIM2.

Promptly, according to system of the present invention, based on the explanation of earlier figures 1 to Fig. 4,, be to realize to comprise the DTU (Data Transfer unit) of MBC (based on the assembly of model) data in order to be converted to PSM data 3 from pim data 2 as the realization form of MDA.So-called MBC data, be to be the meaning of assembly (portion's product) data considered of center with the model, be equivalent to upstream (being equivalent to pim data) design with assembly (structure pim data MBC described later) data and conversion usefulness assembly (pim data described later/PSM data-switching MBC) data that are injected into the downstream from the upstream.Though at length do not record and narrate in the present embodiment, utilize downstream (being equivalent to the PSM data) design can carry out the modeling of PSM data yet with data package (making up PSM data MBC).[/] of pim data/PSM data has the meaning between pim data and PSM data, means mutual conversion.

Below, describe for relating to a kind of embodiment that is converted to the DTU (Data Transfer unit) of PSM data from pim data of the present invention with reference to Fig. 5.

Making up pim data is to have recorded and narrated the action of the inscape of pim data 2 and this each inscape or in conjunction with the data of situation with MBC data 21.

PIM modeling portion 22 has optionally to obtain and makes up pim data with MBC data 21, relate to the business logic layer not by the difference of platform and about the function in the design of upstream.The resulting data of result by these modeling portion 22 designs are pim data 2.Pim data 2 comprises class figure, sequence chart, state transition diagram etc., and they are made into XML (eXtensible Markup Language) file.

PIM check portion 23 checks the appropriate property of the pim data of being made by PIM modeling portion 22 2.So-called appropriate pim data 2 is meant, for example satisfying (a) pim data 2 does not comprise the structure pim data that it should follow have the key element of the structure type that does not have appointment with MBC data 21 in the UMLProfile of appointment, (b) incidence relation (tie lines) between the key element that comprises in the pim data 2 is followed and is made up pim data with the specified incidence relation pattern of MBC data 21, and (c) form of pim data 2 is followed the DTD (Document TypeDefinition) of XM1 and the data of specifying the DTD of the form of preserving uml model according to XMI.Whether the above-mentioned condition of affirmation of upchecking of appropriate property satisfies is carried out.

So-called structure type is meant the thing of the title of having added the characteristic of representing the next class to be the upper class with respect to this next class.Characteristic at this for example is meant [class is function (processing)] and [class is for handling (service)] and [class is process object (entity)] etc.

Pim data/PSM data conversion rule is provided with the thing of data 24 for using when pim data is converted to the PSM data, be the data that comprise to using the link information of MBC document to the conversion that pim data is suitable for.

Fig. 6 is the figure of the processing of representation model compiler 26 at length.In the example of Fig. 6, pim data/PSM data conversion rule is provided with data 24 and is " XSLT " TMBC4Struts and " XSLT " TMBCStrutsWS.In the example of Fig. 6, pim data/PSM data conversion rule is provided with pim data/PSM data-switching that the arrow of data 24 with dashed lines connects and is illustrated in pim data/PSM data conversion rule with MBC data 25 and is provided with in the data 24 designated.

That is to say, be the pim data of " XSLT " TMBC4Struts/when the PSM data conversion rule is provided with data 24, appointment is referred to as pim data/PSM data-switching MBC data 25 of " XSLT " default, " XSLT " association, " XSLT ", processPackage, " XSLT " servicePackage, " XSLT " entityPackage, " XSLT " rulePackage, promptly, record is read each pim data/PSM data-switching MBC data 25 to the link information of each pim data/PSM data-switching with MBC data 25.

At each transformation rule the XSLT that records and narrates in the data 24 being set is the ellipsis of XSL Transformations (XSL conversion).XSL is Extensible Stylesheet Language: the ellipsis of Extensible Stylesheet Language (XSL).This becomes the rule that is used to record and narrate for the document transformation rule record of the mark according to following XML.This XML is mainly used in that be converted to from XML document can be when the html document that Web browser is represented, but in system of the present invention, is used for for the record to the transformation rule of the uml model represented with XML document.

Struts is called structure type, by the Jakarta of Apache financial group (Jia Kalute of its financial group of Ah handkerchief) project exploitation [framework], moving on server, receive the request that comes from Web browser, is the software that can access the subsystem of suitable business logic in view of the above in order to make.

Pim data/PSM data-switching is data of using when pim data 2 is converted to PSM data 3 with MBC data 25, for example, specific label (key element) effect that comprises in the XML data to the class figure of the pim data 2 of expression input, based on the content of this label (key element) by in the XML data of the class figure of expression PSM data 3, appending the data that new label (key element) uses when changing.Fig. 9 is the example of pim data/PSM data-switching with MBC data 25, is the example that is called " XSLT " processPackage among Fig. 6, realizes by the XSLT style sheet.Specifically, pim data/PSM data-switching with the MBC data 25 for to represent＜duplicate the class of self,＜add Actiou in the back of Class name etc. the data of definition content of transformation rule.

Model compiler 26 is made of such build instrumental function 29 of Fig. 6 and transform engine 27.This model compiler 26 is called model compiler by the user from keyboard, and input command waits and starts.When this starts, the place that the pim data 2 that model compiler 26 should be imported as parameter appointment (input) for order, the PSM data 3 that should export are changed Config data 28 in addition.

Build instrumental function 29 serves as that the starting and the change of transform engine 27 are carried out in the basis with conversion Config data 28 (build.xml in the example of Fig. 6) for example.This result, transform engine 27 is as the thing of result for exporting of PSM data 3.Not expression among the figure, as the running environment of model compiler 26, Java (trade mark) is necessary (inscape).

Conversion Config data 28 are transform engine 27 data necessary when starting of model compiler 26.In the example of Fig. 6, conversion Config data are the file data that is called build.xml, illustrate in the example of Fig. 8 as build.xml.Fig. 8＜property name=" TMBC " value=" TMBC4Struts "/record be that expression specifies J2EE+Struts (representing corresponding J2EE and Struts) with transformation rule data 24 to be set.In the present embodiment, transform engine 27 is according to the starting indication starting from build instrumental function 29, by reading the function that conversion is changed with MBC data 25.For example, realize by the XSLT engine function.

That is to say, transform engine 27 is selected to read any one pim data/PSM data conversion rule based on the conversion Config data 28 that provide from build instrumental function 29 (being the build.xml file data this example) data 24 (in the example of Fig. 8, reading " XSLT " TMBC4Struts) is set.Then, the link information of recording and narrating in the data 24 is set based on pim data/PSM data conversion rule of selecting, transform engine 27 reads conversion and uses MBC data 25 (in the example of Fig. 6, pim data/PSM data-switching of " XSLT " default, " XSLT " association, " XSLT " processPackage etc. is read with MBC data 25).Then, transform engine 27 utilizes the conversion of reading with MBC data 25 pim data 2 that is input to model compiler 26 to be converted to PSM data 3, output PSM data 3.

The structure pim data of representing among Fig. 5 is provided with data 24, pim data/PSM data-switching with MBC data 21, pim data/PSM data conversion rule and is made into MBC data 25 etc., respectively by memory in the memory storage of hard disk etc.Promptly, making up pim data is provided with data 24 by memory in memory storage 21a, pim data/PSM data conversion rule with MBC data 21 and is remembered in memory storage 25a with MBC data 25 in memory storage 24a, pim data/PSM data-switching by memory.These memory storages can be that the space of a memory storage is separately remembered or also can be the structure of remembering in dividing other memory storage, also can be the structures according to the hardware of the storer beyond the hard disk etc.

Conversion process under above inscape is carried out with following method.That is to say, 1. starting

model compiler

26,2. starting transform engine 27, afterwards, 3. read transformation rule be provided with 24,4. read conversion with the MBC data, then, 5. read pim data, 6. the check pim data appropriate property, 7. carry out conversion process, 8. write out PSM data after the conversion based on the data that read.

It is as follows in detail that each is handled.

(1) model compiler 26 is called model compiler by the user from keyboard, and input command waits and starts.When this starts, the place that the pim data that model compiler 26 should be imported as parameter appointment (input) for order, the PSM data that should export are changed the Config data in addition.

(2) starting of the transform engine 27 in the model compiler 26 is called by the transform engine 27 of conversion Config data appointment by model compiler and is carried out.In fact, use the build instrumental function 29 that has among Fig. 6, read in transform engine 27 with MBC data 25 and start by pim data/PSM data conversion rule being provided with data 24 and pim data/PSM data-switching.At this moment, in transform engine 27 (in fact with the build instrumental function 29 of Fig. 6 is collaborative carry out), specify 26 appointments of (transmission) model compiler pim data 2, PSM data 3, change with the Config28 data in the transformation rule of appointment data name is set, the pim data of transform engine 27 appointments/PSM data conversion rule is provided with data 24 and just can be read.

(3) reading of data 24 is set is that a pim data/PSM data conversion rule of specifying the transformation rule of (transmissions) to be provided with when reading corresponding conversion engine 27 starting by transform engine 27 is provided with data 24 and carries out to pim data/PSM data conversion rule.Be provided with in the data 24 in the pim data that reads/PSM data conversion rule, specified the pim data/PSM data-switching that should be suitable for set (comprising) to the link information of pim data/PSM data-switching with the MBC data with MBC data 25 to pim data 2.

(4) pim data/PSM data-switching is by reading pim data/when the PSM data conversion rule is provided with data 24 with reading of MBC data 25, and transform engine 27 reads pim data/PSM data conversion rule and is provided with that each conversion of appointments is carried out with MBC data 25 in the data 24.

(5) reading of pim data is to specify the pim data 2 of (transmission) to carry out when reading transform engine 27 startings by transform engine 27.

(6) check of pim data 2 is to carry out by the appropriate property of transform engine 27 check pim datas 2.

Under the situation of the pim data of imappropriate (not to), the wrong and end process in this expression.

(7) conversion process is following is performed like that.That is to say that transform engine 27 uses the conversion rule information of MBC data definition sequentially the key element of this application of rules in pim data or the set of key element based on the conversion of reading.The mode that is suitable for is, key element in the pim data is seen with the order from last beginning, simultaneously (for example according to the relative importance value that is suitable for of transformation rule, the conversion of preferential first appointment is with transformation rule of MBC data etc.) therefrom select some, be suitable for this rule, the PSM document that is suitable for result's generation is all replaced.

In this case, after certain pim data/PSM data-switching usefulness MBC data 25 conversions, next pim data/when the PSM data-switching exists with MBC data 25, this pim data/PSM data-switching are applied to the pim data 2 replaced with MBC data 25 by means of pim data/PSM data-switching with MBC data 25.Therefore, exist under the situation of a plurality of pim datas/PSM data-switching with MBC data 25, the pim data 2 after replacing with MBC data 25 by means of last pim data/PSM data-switching becomes PSM data 3.The applicable pattern of the transformation rule of pim data/PSM data-switching usefulness MBC data 25 definition is not limited to aforesaid way according to the style of transform engine.

(8) writing out of PSM data 3 is that PSM data 3 the result of above-mentioned conversion process generates are write out (output) so that the user can take out.

About from the conversion process of pim data 2 to PSM data 3, the example when below pim data 2 being based on the data of PSER describes.Especially above-mentioned pim data/PSM data conversion rule is provided with data 24 and is converted engine 27 and reads, the processing when pim data/PSM data-switching that the pim data that is read/PSM data conversion rule is provided with data 24 appointments is read with the MBC data describes.At first, PSER is meant the structure MBC data of any one pim data 2 that is used to make " process ", " service ", " entity ", " rule ".

Illustrate that with Fig. 7 the module data of processing is that control is around the order of a series of processing of a business function and the module data of state transition.For example, [commodity selection] and [acknowledgement of orders] and data such as [order are determined] are arranged in the Web shop.The module data of service is for providing the module data of business processing necessary logic when carrying out business processing.For example, [item retrieves] and [input of shopping cart commodity] and data such as [order distribution] are arranged in the Web shop.The module data of entity is the business datum that is kept in the database.For example, [order detail] and data such as [dispensing documents] are arranged in the Web shop.The module data of rule is for providing the module data of checking logic and calculating formula.The benchmark (inspection logic) of the condition that whether satisfies [shopping cart is for empty] and [Amount in Total＜1,000,000 yen] and [commodity are in the storehouse] that could check as order etc. is arranged in the Web shop.

This PSER when system constructing corresponding to requiring style.That is to say,, extract out to being easy to information owing to require style to have following project information usually.As project, the business function (being equivalent to handle) seen from the user's of system angle is arranged, for the rule (being equivalent to rule) of the logic (being equivalent to service) of carrying out necessary expression of business function and input etc., the data (being equivalent to entity) that become process object such as input and output project, professional inspection logic and trigger etc.

At first, below the pim data 2 from P (processing) is described to the conversion of PSM data 3.The conversion process of P (processing) uses MBC data 25 by business processing (in the example of Fig. 6 with pim data/PSM data-switching, be " XSLT " processPackage, this is the meaning that is called the XSLT file of processPackage.xsl) be converted engine 27 and read and carry out.The figure of the pim data 2 that Figure 10 handles for expression and the correspondence of PSM data 3.

[for being independent of the information of platform, according to the information of the system of the processing of the function of system and this function and the relation between objects performance that should handle] in the technical scheme of the present invention is corresponding to pim data 2.
