To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
See also accompanying drawing 1, be the process flow diagram of the disclosed first kind of heterogeneous data source standardized method of the embodiment of the invention, said method is applied to just be present in the municipal corporation in the distributed privately owned term system.Each privately owned term system comprises with standard terminology system centre and keeps synchronous standard terminology, and this method can comprise:
Step S101: after receiving the standardization request of privately owned term, obtain the normal structure of the mapping relations of said standard terminology and said privately owned term, said standard terminology business scenario of living in;
With medical institutions is example, and the foundation of standard terminology can be according to the many terminology standards and the term of domestic and international medical industry definition, like HL7, GB/T, Ministry of Public Health's health account data standard, electronic health record data standard or the like.But before each standard was born, just there had been the terminology of oneself in each medical institutions of hospital.After standard terminology has been arranged, just need the privately owned term of each medical institutions perhaps be remarked additionally with standard terminology is corresponding one by one; For addressing this problem; Be necessary to develop a cover terminology management system; This cover system can carry out unified management and maintenance to different terminology standards, and unified term queries interface can externally be provided, and realizes term mapping and conversion through the term queries interface.
Share in order to realize the medical data between different institutions; Unified standard must be arranged, select same form of presentation for use, the same as language; When the language of saying same country and corresponding word; Can understand mutually between the people, for PC World, the term that computing machine can be discerned is the basis of mutual understanding between system.
The present invention is as shown in Figure 2 to the maintenance of term; Be the disclosed a kind of synoptic diagram that privately owned term is safeguarded of the embodiment of the invention; Because the statement of the privately owned term of the same department of each medical institutions itself is unified, and be that standard terminology or privately owned term have nothing to do, the expression of a concrete term is a codomain; All be to describe with the structure of < coding, value >.So in system; Different terms is adopted the identical construction mode, and wherein the data general designation of a certain concrete professional meaning has been represented in < term territory >, such as sex; Just represent a term territory; The traffic value that it comprised is a tabulation, and each term value all has clear and definite professional meaning in the tabulation, and < sex>this term territory has just comprised man, woman etc.; Of a sort term territory is summarised in and has constituted terminology together.For the term system and the privately owned term system of standard, because professional meaning communicates, difference is that the expression way of encoding with being worth is different; Represent the sex man such as some hospital with (M, the male sex), and some hospital uses (1; The man) represent sex man, is the mapping that can set up different coding through professional meaning between the two, and corresponding mapping method adopts the mode of coding and value to manage; Above example in, safeguard between coding < M>and the coding < 1>and shine upon, when all codings shine upon the administration-management of going forward side by side when managing; With the basis that forms standardization of terminology, key message comprises < terminology, term territory; The term value>three other mappings of level, promptly manage from these three information, corresponding maintenance of information in system.
Concrete; Can at first obtain the address of the normal structure of the mapping relations address that needs standardized privately owned term and corresponding standard term and said standard terminology scene of living in, the address that belongs to according to their again obtains the mapping relations of said standard terminology and said privately owned term and the normal structure of said standard terminology business scenario of living in.
Said standard terminology business scenario structure of living in is meant, with its normal structure possibility difference of different departments of a kind of mechanism, for example: inpatient department in the medical institutions and clinic; Because the information of inpatient department possibly can be written as < inpatient department, name, sick room number for room number, hospital stays, name and home address of patient or the like; Hospital stays >, and the information of clinic maybe for: medical history, illness, the cause of disease and name or the like can be written as < clinic; Name, medical history, illness; The cause of disease >, the difference of information possibly cause structure different, even message length also maybe be different; Can stipulate to be in the construction standard of the term of this business scenario like this according to business scenario, construction standard also can be the same certainly, for example; The packets of information of primary sector is contained in secondary sector, and the structure of these two departments can be the same so, does not exist the information with said secondary sector will be set to sky in the only said primary sector.
In order to satisfy distributed computing; The present invention uses uniform way to manage standard terminology and privately owned term, but physically separates, and is as shown in Figure 3; The synoptic diagram of Fig. 3 for separating on the disclosed a kind of standard terminology of the embodiment of the invention and the privately owned term physical; Standard terminology will be by centralized stores in standard terminology system centre, and the privately owned terminology of medical institutions of every family will be retained in the institute, and the incidence relation in standard terminology system centre and the institute between privately owned term is maintained in the institute; Standard terminology system centre will be synchronized in the institute by standard terminology simultaneously, thereby realizes the unification of personalisation process in centralized and unified issue and the institute.Adopt this mode; The privately owned standard of each hospital can not have influence on the data of other hospitals; When carrying out exchanges data; All data all can become the value of standard in the court's internal conversion, in institute, accomplish to practice thrift the center calculation resource except realizing the standardization of data computing, make that also output data is exactly the normal data that institute's external system can be discerned in the institute.
Language as the people is the same, except the word of terminology, term territory and term value need be unified, also need on grammer, unify statement; Such as < man>this speech, only be present in the concrete linguistic context, can speak of its meaning; Such as there being the people to be Wang Sainan, < man>this speech is wherein arranged, and in another words < I am the man >; < man>word is also arranged, but the implication of its expression is different, the preferred XSD that adopts carries out constraint in this respect among the present invention.
Ripe at present exchanges data form has the mode of XML, also adopt XML to carry out exchanges data among the present invention, but the agreement of data itself is also wanted adherence to standard.The present invention adopts the XSD of present maturation to realize this management with the method that the term coding combines; XSD is kind of an XML schema languages; The XML framework is that the XML of XML document set describes, so the present invention adopts XSD to realize the unified statement of XML, makes the node in the framework carry out related with term during term is managed simultaneously; In obtaining hospital after the data; Because standard terminology that each node is corresponding in the concrete XML document and the mapping between privately owned term can realize standardization to handle automatically by instantiation through program, guaranteed that through XSD the linguistic context at data places is consistent.As shown in Figure 4; Fig. 4 is the synoptic diagram that how to guarantee that the linguistic context at database place is consistent for XSD; The left side is the segment of XSD < sex>node, and wherein codeSystem and code have represented the coding of term system and term respectively, through these essential options; XSD realized and term service between joint-action mechanism basis, final program can reach data standard according to these mapping relations and handle.Through said method, realized the standardization of term, the linguistic context expression consistency constraint of term, and the basis of the distributed arithmetic of realizing.
Step S102: gather the privately owned term in the said privately owned term system;
Concrete, at first obtain the first address that need carry out standardized privately owned term, and then obtain said privately owned term according to said first address.
Step S103: the privately owned structure of the residing business scenario of said privately owned term is carried out standardization according to the normal structure of said standard terminology corresponding service scene of living in;
Because the privately owned structure of said privately owned term business scenario of living in maybe be inconsistent with the normal structure of the residing business scenario of corresponding standard term, so need be with the privately owned construction standardization of said privately owned term business scenario of living in.
Step S104: each association in the privately owned term after the poll construction standardization, each association is carried out standardization according to the mapping relations of said standard terminology and said privately owned term.
Step S104 has realized the mapping between the privately owned terminology data unit after normal structure data element and the standardization of standard terminology business scenario of living in.Minimum composition unit in the said data element general reference structural data just refers to " each association ", and whole like this standardisation process has just been accomplished.
Step S104 can carry out in step S103 front, just just for the convenient order of having stipulated of drawing.If step S104 is in step S103 front, so original step S104 is each association in the privately owned term of poll, and each association is carried out standardization according to the mapping relations of said standard terminology and said privately owned term; Step S103 originally is for carrying out standardization with the privately owned structure of the residing business scenario of privately owned term behind the data normalization according to the normal structure of said standard terminology corresponding service scene of living in.
Why each privately owned term system need change into the privately owned term of self standard terminology is for when the privately owned term after the standardization of oneself is sent to other privately owned term system; Other privately owned term system also can be discerned; During privately owned term after receiving the standardization that other privately owned term system send over, self system also can discern the privately owned term of other privately owned term system.So behind step S104, can also comprise step: said privately owned term system will receive the privately owned term after other privately owned term system standardization and/or the privately owned term after the standardization will be sent to other privately owned term system.
The embodiment of the invention; After the standardization request of receiving privately owned term; Obtain the normal structure of the mapping relations of said standard terminology and said privately owned term, said standard terminology business scenario of living in; Because the normal structure of said mapping relations and said standard terminology business scenario of living in all is stored in the privately owned term system, said privately owned term system just municipal corporation converts self privately owned term into standard terminology according to these standards, thereby constructs the unified statement basis of heterogeneous data source; Reach the unified statement of unifying the information of mechanism from different regions, realize sharing of real meaning.The embodiment of the invention is aimed at distributed running environment design; Privately owned term in the same mechanism that is distributed in various places carries out Unified Treatment; Just carrying out standardized is each privately owned term system rather than standard terminology system centre, can make standardized speed faster like this.
Embodiment two
In the present embodiment with detailed description obtain standard terminology and said privately owned term the concrete grammar of mapping relations; See also Fig. 5; Be the disclosed a kind of process flow diagram that obtains the mapping relations method of standard terminology and said privately owned term of the embodiment of the invention, this method can comprise:
Step S501: when receiving the request that shows structure term service interface, directs display module shows said interface;
Said structure term service interface comprises: the standard terminology collection that privately owned terminology and said privately owned terminology are corresponding, the privately owned term territory in the said privately owned terminology and the standard terminology territory corresponding and the privately owned term value in the said privately owned terminology with said privately owned term territory and with the corresponding standard terminology value of said privately owned term value.
Step S502: to the said privately owned terminology in the said structure term service interface, said privately owned term territory, said privately owned term value, said standard terminology collection, said standard terminology territory and said standard terminology value assignment;
Privately owned term in the embodiment of the invention and the corresponding relation between the standard terminology can be filled in by the staff; Same like this standard terminology just can corresponding a plurality of privately owned terms; Perhaps want to carry out the data friendship alternately between two hospitals; And need not pass through standard terminology, and can let the other side's the privately owned term be standard terminology so if want the data that let the other side discern oneself, so also can realize data interaction.
Step S503: the mapping relations that generate privately owned term territory described in the said privately owned terminology.
Concrete, the privately owned terminology and the standard terminology collection that fill are a pair of mapping relations, and the privately owned term territory and the standard terminology territory that fill are a pair of mapping relations, and the privately owned term value and the standard terminology value that fill are a pair of mapping relations.
The embodiment of the invention; Because the mapping relations of said privately owned term and standard terminology are obtained from said structure term service interface; And the parameter in the said structure term service interface is filled in by the system manager, so the mapping relations of privately owned term and standard terminology can be changed.
Embodiment three
See also Fig. 6, be the process flow diagram of the disclosed second heterogeneous data source standardized method of the embodiment of the invention, said method is applied to just be present in the municipal corporation in the distributed privately owned term system.Each privately owned term system comprises with standard terminology system centre and keeps synchronous standard terminology, and this method can comprise:
Step S601: the kind of judging each privately owned terminology in the privately owned term system;
The kind of said privately owned terminology can be meant the department at said privately owned term place; The department at place is different; The residing business scenario of said privately owned term is also just different; Thereby the privately owned structure of said privately owned term business scenario of living in maybe be different, and the different corresponding normal structures of privately owned structure maybe be different, so at first judge the kind of each privately owned terminology.
Step S602: obtain in each privately owned terminology in term territory, term value and the respective standard term system term territory, term value in the corresponding standard terminology in the heart;
Concrete; After obtaining a certain privately owned terminology; Travel through privately owned term territory and corresponding privately owned term value in this privately owned terminology, obtaining the standard terminology collection that has the identical services scene with this privately owned terminology then, in standard terminology territory and the corresponding standard terminology value that this standard terminology of traversal is concentrated; Then with privately owned term territory with; The standard terminology territory (for example privately owned term is a sex, and the standard terminology territory also is a sex so) that has same type with this privately owned term territory is corresponding, and the value in said privately owned term territory is corresponding with the value in the said standard terminology territory.For example; After obtaining this privately owned terminology of inpatient department; Traversal inpatient department this set, finding has in the inpatient department: sex, these two privately owned term territories of sick room number, and corresponding sex, the list value of sick room number; For example there are men and women for sex, and " man ", " woman " are exactly the value in this privately owned term territory of sex.Obtaining the standard terminology collection that has identical services with inpatient department; For example be the department of being in hospital, and in the department of being in hospital sex and sick room number arranged also, but be to represent sex in the standard terminology with M; Represent the disease room number with Num; So just that M is corresponding with sex, Num is corresponding with sick room number, then with the value among the M accordingly with sex in value corresponding.
Step S603:, obtain the mapping relations of privately owned term and standard terminology according to the corresponding relation of each privately owned terminology and corresponding standard terminology, each privately owned term territory and corresponding standard term territory and each privately owned term and corresponding standard term;
Step S601 can carry out once when carrying out privately owned standardization of terminology initial to step S603; That is to say; Only need obtain once the mapping relations of privately owned term and standard terminology; When privately owned standardization of terminology was arranged, can directly from the mapping relations that obtained, search needed the corresponding mapping relations of standardized privately owned term follow-up.Having any different among the mapping relations of obtaining privately owned term and standard terminology in the present embodiment and the embodiment two; Can make amendment to said mapping relations according to actual conditions by the system manager among the embodiment two; Can not revise after obtaining mapping relations in the present embodiment; But owing to omitted this step of generation mapping relations each standardized the time, thereby speed is faster.Step S604: after receiving the standardization request of privately owned term, obtaining needs standardized standard terminology and the mapping relations of corresponding said privately owned term, the normal structure of said standard terminology business scenario of living in;
Step S605: collection needs the standardized privately owned term of needs in the standardized said privately owned term system;
Step S606: the privately owned structure of the residing business scenario of said privately owned term is carried out standardization according to the normal structure of said standard terminology corresponding service scene of living in;
Step S607: each association in the privately owned term after the poll construction standardization, each association is carried out standardization according to the mapping relations of said standard terminology and said privately owned term.
Can also comprise step S608 behind the step S607: the privately owned term behind structure and the data normalization is generated the document that meets said standard terminology structure, and storage.Concrete, can import the privately owned term behind structure and the data normalization into the structure device, said structure device generates standard document automatically.
So the privately owned term after the standardization is stored; When once more this privately owned term being carried out standardization so, if the data in the privately owned term do not change (for example, if inpatient department does not increase new patient; There is not the people that leaves hospital because of rehabilitation yet; The data of inpatient department are constant so), so just need not change, the document that can directly call this privately owned term gets final product.
This method can also comprise: step S609: the standard terminology according to said standard terminology system centre upgrades the standard terminology in the said privately owned term system.With medical institutions is example, if a kind of new disease, the title of this new disease also has a standard terminology so, at this moment also should this standard terminology be increased in each privately owned term system.
Step S609 can be before or after any step, so just just for the convenient order of having stipulated of drawing.
In the embodiment of the invention; At first generate the mapping relations of a privately owned term and standard terminology, then when carrying out standardization, directly from mapping relations, search and get final product; And do not need all to generate one time before carrying out standardization mapping relations, thereby saved the time at every turn.
Describe method in detail among the disclosed embodiment of the invention described above, can adopt the device of various ways to realize, therefore the invention also discloses three kinds of systems, provide concrete embodiment below and be elaborated for method of the present invention.
