Specific embodiment
Below in conjunction with attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Usually exist The component of the embodiment of the present invention described and illustrated in attached drawing can configure to arrange and design with a variety of herein.Cause This, the detailed description of the embodiment of the present invention to providing in the accompanying drawings is not intended to limit claimed invention below Scope, but it is merely representative of the selected embodiment of the present invention.Based on the embodiment of the present invention, those skilled in the art are not doing The all other embodiment obtained on the premise of going out creative work, belongs to the scope of protection of the invention.
Interconnection between existing ERP system (being referred to as ERP software or ERP software system), passes through server The mode of open standard client development interface realizes that this mutual contact mode causes the problem of many, such as：Interconnection when Wait, it is necessary to by server switching, transmitted information can be obtained by server, monitored between ERP system；Once server Interface upgrade, the ERP system being attached thereto just into will develop again upgrading etc., based on this, an embodiment of the present invention provides The means of communication, device and system between a kind of ERP system, to realize the Direct Communication between ERP system.For ease of to this implementation Example is understood, the method that Direct Communication is carried out between a kind of ERP system disclosed in the embodiment of the present invention is carried out first detailed It is thin to introduce.
It is each in the data communication method between the ERP system that the embodiment of the present invention is provided referring to shown in Fig. 1-Fig. 4 The ERP system of enterprise follows identical data communication specification, each communication pipe of the ERP system with other ERP systems System communication connection is managed, each ERP system includes one or more data communication entities, and each data communication is real Body obtains at least one address from respective communication management system in advance；
When specific implementation, basic concept there are five the data communication specifications of data communication is carried out between ERP system： 1st, data communication entity；2nd, address；3rd, data communication bag；4th, data communication object；5th, data communication mandate.
1st, data communication entity：Refer to the entity that data communication is carried out between ERP system.The data communication of ERP software is real Body has a essential characteristic：The data communication entity is the tissue of a progress separate traffic accounting.The specific boundary of data communication entity Set pattern then depends on the developer of the ERP system.Therefore, data communication entity needs ERP software provider to define and safeguard. Different with business model according to ERP software expression, the confining method of entity is also different, mainly includes：Based on software module Cloud ERP software of the license with traditional ERP software of user's licensing outlet and based on online ordering sale.
(1) traditional ERP software includes according to organization and administration mode：Single set of books is knitted based on single group, single group knits more sets of books and use In more organizational structures of group management.Here tissue refers to a legal person, a company or the list of business independent accounting Position etc..Single group knits single set of books software and corresponds to a data communication entity；Single group knits each set of books of more set of books softwares and corresponds to a number According to communication entity；It is multigroup to knit tissue one data communication entity of correspondence that each separate traffic is adjusted in ERP software.
(2) management pattern of organization of cloud ERP software includes：1. the management pattern of organization of traditional ERP software is continued to use, this kind of cloud The data communication entity of ERP software defines consistent with the above method.2. cloud ERP software client shares storage, this kind of ERP software Management pattern of organization is more organizational structures.Therefore, define the mode of data communication entity only needs one kind can under normal circumstances To solve：The tissue that each separate traffic is adjusted corresponds to a data communication entity.According to foregoing description, in each ERP Include one or more data communication entities in system, the communication between ERP system, is that the data communication of ERP is real actually Communication between body.
2nd, address：For physical location of the mark data communication entity in internet.Due to each ERP manufacturer softwares Expression way it is different, the expression way of address is also different.Address needs ERP manufacturers to define rule and safeguard, i.e., each ERP manufacturers can establish the communication management system for the ERP system developed corresponding to it, which can be each number At least one address is distributed according to communication entity.Traditional ERP software is deployed among intranet, usually, each Data communication entity can correspond to a data communication address, and this kind of data communication address can generally be established with TCP/IP addresses Correspondence.A kind of deployment way of cloud ERP software system is to provide service by software instances collection, and data communication service is it In a basic module.Data communication service is deployed on multiple servers, and is managed by balancing dynamic load.It is this Deployment way so that the expression way of data communication address is that one group of data communication address corresponds to one group of data communication entity, each A data communication entity can all correspond to multiple addresses.Therefore, the address of data communication entity is dynamic to give tacit consent to Address is the address for being successfully established data communication link last time.Connecting unsuccessful then connected to communication management system transmission please It asks, communication management system sends an available address and attempts connection automatically.There are four fundamentals for address：Client's classification, Customer ID, acquiescence TCP/IP addresses and port.
3rd, data communication bag：The form of data communication bag, logical construction are defined by ERP software manufacturer, and formulate with it is other The data of the isomery of ERP system lead to the rule that bag data is converted.In principle, it is different between other ERP systems in order to realize The format conversion of the data communication bag of structure, data communication bag only define data type, logical construction, do not define flow data.This The realization for requiring the communication traffic of ERP system is based on data-driven rather than Flow driving.Each comfortable software production of ERP manufacturers The operations such as conversion, parsing, processing, storage of the inner realization of product (i.e. ERP system) to meeting oneself definition format data communication bag.
Data communication bag in the present embodiment is made of four partial contents：Format version, communication object, user data, category Property.Format version refers to that the data communication bag follows the data communication bag form of which ERP manufacturer, format version etc..Communication pair As if refer to receiving side data communication entity, receiving side data communication object and sender's data communication entity, sender's data and lead to Interrogate object etc..Attribute is mainly used for marking the essential characteristic of the data communication bag, for example level of confidentiality, priority, receipt etc..Level of confidentiality refers to Whether data communication bag, which needs, is encrypted.Priority refers to priority level of the data communication bag when sending.Receipt is used to send Side confirms whether other side receives data.It can realize that flow cooperates with by receipt between ERP system.
It, can be by the side that communicates, when sending data, by data during different ERP systems is communicated Communication bag changes into the form that the opposing party can identify, meanwhile, it is sent out when data are received, then by data communication bag by other side The form that the format conversion sent can be identified into oneself；Or the both sides of communication convert data communication bag when sending data By unified format conversion it is what oneself can be identified when data are received, then by data communication bag into unified form Form.
4th, data communication object：ERP system generally has multiple data communication objects, is for example authorized for communication between entity Data communication object, the data communication object for business cooperation, data communication object for reporting-form composing etc..Data communication There are four basic functions for object：(1) data to be sent are encapsulated with the data communication bag form of configuration；(2) the number of heterogeneous formats The data communication bag that isomorphism form is changed into according to communication bag (realizes the conversion of data communication bag form, by oneself None- identified Data communication bag format conversion be the data communication bag form that oneself can identify)；(3) data accepted communication bag team is parsed Row；(4) operations, the operation such as being processed, store to having parsed data according to business rule can not be in data communication object It realizes, either corresponding with service can be called to handle by the way that business datum is sent to corresponding service routine processing.
Data communication object is needed before data are sent according to pre-set data communication bag form logarithm in ERP system According to being packaged；It establishes and connects with the data communication entity of data communication bag recipient after the completion of encapsulation, and send data.Number According between communication entity data transmission work can from data communication object it is independent, by data transport service program Lai Unified management；Data transport service program major function is foundation, the transmission of data communication link between two data communication entities Data receive data and give data communication object handles the data sending received.
Data communication object first determines whether data communication bag is isomery number in the data communication bag that processing receives It is wrapped according to communication, if isomery bag then needs to convert the data communication bag of the system form.The number for meeting the system form is parsed again It is wrapped according to communication, then data is processed, stores etc. to handle or be sent to data communication bag association service and handle.
5th, data communication mandate：Enterprise first has to obtain the mandate of other side with contact unit progress data communication.Contact is single Position may have multiple ERP software systems, therefore unit of coming and going will specify and carry out data communication, the data of business cooperation with the enterprise Communication entity.ERP software provider application of the enterprise to the data communication entity carries out data communication and business with contact unit Collaboration.Manufacturer is sent to this application the data communication entity of contact unit, which carries out double with the enterprise after accepting applications To communication key certification.Communication two party can be carried out communication connection after intersecting mandate, be authorized until a side cancels communicating.
The flow chart of data communication method between ERP system shown in Figure 1, for convenience, below will be with two It is illustrated exemplified by communication between a data communication entity, wherein, the first data communication entity belongs to the ERP systems of the first enterprise System, the second data communication entity belong to the ERP system of the second enterprise, and the means of communication between the ERP system specifically include：
S101：The communication that the first data communication entity in the ERP system of first enterprise passes through the ERP system of the second enterprise Management system sends data communication application to the second data communication entity of the ERP system of second enterprise, and the data are led to News application includes：The address of first data communication entity, ERP system mark, the ERP system of the second enterprise of the first enterprise Mark；
When specific implementation, the manufacturer of other ERP softwares (i.e. ERP system) has been known in advance in ERP system, and The TCP/IP addresses for the communication management system corresponding to its ERP system developed established by ERP software are also by other ERP system have learned that in advance, it is preferred that be previously stored with the communication of other ERP systems in each ERP system The TCP/IP addresses of management system, can be directly by prestoring when needing to establish connection with other ERP systems Other ERP systems communication management system corresponding to TCP/IP addresses realize the communication management system with other ERP systems Communication connection is stood in construction in a systematic way.Alternatively, belong to which ERP software manufacturer is developed in the ERP system for being aware of connection to be established, The address with only corresponding communication management system can be directly obtained by internet.
The first data communication entity in the ERP system for realizing the first enterprise and the in the ERP system of the second enterprise Before the communication of two data communication entities, the first data communication entity can send number to the communication management system of the second communication entity Apply according to communication, the ERP system mark of the second enterprise, the ERP systems of second enterprise are not included in the data communication application System mark is to identify the mark of the ERP system of the second enterprise with the communication management system corresponding to the ERP system of the second enterprise Code, ID number, enterprise name etc., when the second enterprise ERP system communication management system when receiving the data communication application, The ERP system identification (RNC-ID) analytic of the second enterprise can be come out from the data communication application, retrieval and inquisition is carried out according to the mark. And in the communication management system of the ERP system in the second enterprise, it is right with the ERP system of second enterprise mark institute to be previously stored with The address for the second communication entity answered, the address of second communication entity are the communications of the ERP system of the second enterprise Management system is pre-assigned to the second communication entity.After retrieval and inquisition to the address of second communication entity, second The communication management system of the ERP system of enterprise is sent to the according to the address of the second communication entity, by data communication request Two communication entities.
S102：The first data communication entity is exchanged with each other authorization message with the second data communication entity.
When specific implementation, since the first data communication entity passes through the communication of the ERP system of the second enterprise Data communication request is sent to the second data communication entity of the ERP system of the second enterprise by management system, and in the number According to the address and the ERP system mark of the first enterprise for including the first data communication entity in communication request, the second data Communication entity is after the request of this data communication is received, by the address of the first data communication entity and the first enterprise The mark of ERP system from data communication request in parse, then according to the ERP system mark of the first enterprise to determine whether Agree to establish connection, if disagreed, the ERP system of the second enterprise terminates collaboration, if agreeing to establish connection, according to the The address of one enterprise is exchanged with each other authorization message with the second data communication entity.After authorization message has been exchanged with each other, Mean that the first communication entity and the second communication entity can establish the connection with other side according to the authorization message exchanged, The business datum transmitted by business datum or reception other side is sent to other side.
S103：When the first data communication entity determines that current and the second data communication entity has data communication to need When asking, the first data communication entity and the second data communication entity are according to the first data communication entity and described The authorization message of second data communication entity carries out data communication.
Data communication method between the ERP system that the embodiment of the present invention is provided, the ERP system of each enterprise follow phase Same data communication specification, and each ERP system is communicated with the communication management system of other ERP systems and connected, each ERP systems System includes one or more data communication entity, and each data communication entity can be in advance from respective communication management system System obtains at least one address, and the first data communication entity in the ERP system of the first enterprise will be with the second enterprise When the second data communication entity in ERP system carries out data communication, the first data communication entity can be according to itself and second Data communication application is sent to the ERP systems of the second enterprise by the communication connection between the communication management system of the ERP system of enterprise The communication management system of system, the second enterprise of the communication management system of the ERP system of the second enterprise in the data communication application The ERP system of industry identifies, and after the address for finding the second data communication entity, which is sent to second Data communication entity.If the second data communication entity is agreed to be communicated between the first data communication entity, then with regard to root According to the address of the first data communication entity in data communication application, mandate is exchanged with each other with the first data communication entity Information.After two sides have exchanged authorization message, when either side therein has communication need, the first data communication entity with The second data communication entity is according to the authorization message of the first data communication entity and the second data communication entity Data communication is carried out, by the above process, realizes the Direct Communication between ERP system.
In the prior art, the mutual contact mode between ERP software (including traditional ERP and cloud ERP) also rests on last century The client/server when seventies, network just rose, i.e., come real by way of the standard client development interface that server opens Existing, Interface integration is initiated by client dragging, and with the mode clocked flip of timer, this mode efficiency is low, does not have Having still can periodically pull during data transmission, cause the waste of server resource.Thus between ERP system provided by the present invention Data communication method, only when the first data communication entity or the second data communication entity have data communication demand, just meeting Data communication is carried out according to authorization message and other side, departing from server, while is only just initiated the connection when needed, because without It can cause the waste of resource.
Meanwhile in the prior art, the system integrated by interface exploitation is tightly coupled system, poor expandability, server If interface upgrades, the integrated of the ERP system being attached thereto will develop upgrading again.And in the present invention, two data Communication between communication entity only depends on the authorization message of both sides' exchange, and then the address in authorization message carries out Communication, thus do not integrated between ERP system, also there is no server interface upgrading, the collection for the ERP system being attached thereto Into will again develop the problem of upgrading.
In addition, in the prior art, often there are multiple suppliers in an enterprise, also has multiple clients；Between supplier, Between client may also can be there are business contact, therefore, the supply chain where enterprise is a kind of fenestral fabric system, sets of interfaces Artificially gridding thaumatropy can only be realized into hub-and-spoke configuration into mode.The ERP system of as each enterprise integrates more A interface, multiple interfaces are each respectively connected with the ERP system of another enterprise.And in the present invention, as long as the ERP systems of an enterprise It unites to have exchanged with the ERP system of other enterprises and intersects authorization message, can directly be communicated, really form gridding Structure.
In above-mentioned communication process, since the first data communication entity and the second data communication entity will intercourse mandate Information, therefore, the first data communication entity shown in Figure 2 and the second data communication entity are exchanged with each other the stream of authorization message Cheng Tu, this method include：
S201：First data communication entity receives and stores the authorization message of the second data communication entity, and described The authorization message of two data communication entities includes：The address of second data communication entity, the ERP system mark of the second enterprise Know, the data communication bag form that communication connection key, the second data communication entity of the second data communication entity can identify；
When specific implementation, the data transmitted by the first data communication entity are received in the second data communication entity After communication application, the address of the first data communication entity can be parsed from the data communication application, it is logical second Body is proved to be true after interrogation to agree on the premise of being communicated with the first communication entity, can be according to the address of the first data communication entity, it will The authorization message of oneself is sent to the first data communication entity.The authorization message of second data communication entity includes：Second data The address of communication entity, ERP system mark, the communication key of the second data communication entity, the second data of the second enterprise The data communication bag form that communication entity can identify.Wherein, the address of the second data communication entity is to the first data Communication entity and the second data communication entity, which are established, to be connected；The ERP system of second enterprise is identified to the first data communication entity Differentiate whether the authorization message received by it comes from the second communication entity；The connection key of second communication entity be then for The encrypted communication data subsequently received in the first communication entity transmitted by the second communication entity is decrypted when communicating bag；The The data communication bag form that two data communication entities can identify is then to inform the first data communication entity, can know The form of other data communication bag.
S202：The first data communication entity is according to the authorization message of the second data communication entity, to described Two data communication entities send the authorization message of the first data communication entity；The mandate letter of the first data communication entity Breath includes：Communication connection key, the first data communication entity and the second data communication entity of first data communication entity exist The data communication bag form used is given tacit consent to when carrying out data communication.
When specific implementation, mandate of first communication entity due to having been received by the second data communication entity is believed Breath, and contains the address of the second data communication entity in the authorization message of the second data communication entity, thus at this point, the One data communication entity can be connected to the second data communication entity according to the address of the second data communication entity.This When, due to the ERP system of second enterprise of the first data communication entity in the authorization message according to the second data communication entity Mark, judge the authorization message be strictly transmitted by the second data communication entity after, the first data communication entity is according to the The address of two data communication entities sends the authorization message of the first data communication entity to the second data communication entity.It should The authorization message of first data communication entity includes：The communication connection key of first data communication entity, the first data communication Entity and the second data communication entity give tacit consent to the data communication bag form used when carrying out data communication.Wherein, the first number According to the communication connection key of communication entity adding transmitted by the first communication entity is being received for follow-up second communication entity Close communication data communication is decrypted when wrapping；First communication entity is write from memory with the second data communication entity when carrying out data communication Recognizing the data communication bag form used is wrapped for arranging used communication when the two is communicated with the second communication entity Form.
Wherein, the data communication bag form used is given tacit consent to including following several：
The data communication bag form that (1) first data communication entity and the second data communication entity can identify is same Kind, then the data communication bag form that the acquiescence uses is that the first data communication entity and the second data communication entity can The data communication bag form of identification, it should be noted that the first data communication entity and the second data communication entity can be known Other data communication bag form can be a kind of or a variety of, when the data communication bag form that the two can identify is When a variety of, and wherein have and multiple both can identify, then any of which data that will both can be identified The data communication bag form that communication bag form uses by default.
The data communication bag form that (2) first data communication entities and the second data communication entity can identify is different, But the first data communication entity can be by data communication bag format conversion that it can be identified into the second data communication entity It can be the data communication bag form escaped, then the data communication bag form that can identify the second data communication entity The data communication bag form used by default.
The data communication bag form that (3) first data communication entities and the second data communication entity can identify is different, The data communication bag form that the data communication bag format conversion that oneself can be identified can be neither identified into other side, It but both can be by the data communication bag format conversion of oneself identification into the third data communication bag form, then by the 3rd The data communication bag form that kind data communication bag form uses by default.
In addition, shown in Figure 3, fact Example of the present invention also provides a kind of first data communication entity and the second data communication The flow chart that the authorization message that entity is exchanged with each other according to the two is communicated, specifically includes：
S301：The first data communication entity is real according to first data communication with the second data communication entity The authorization message of body and the second data communication entity establishes connection；
When specific implementation, due to mutually being handed between the first data communication entity and the second data communication entity Changed authorization message, meanwhile, both had learned that the address of other side, need to other side send business datum when Wait, can connectivity request message be sent to other side according to the address of other side, after other side agrees to establish connection, establish with it is right Then connection between side, according to established connection, business datum is sent to other side.For example, when the first communication entity is thought It, can be according to the address of the second data communication entity to second when sending business datum to the second data communication entity Data communication entity sends connectivity request message, when the second data communication entity receives the communication request information, and agreement After being communicated with the first data communication entity, connection response information can be sent to the first data communication entity, so as to establish the two Between connection., whereas if being that the second data communication entity is wanted to send business datum to the first data communication entity, then need Communication request information first is sent to a data communication entity, is receiving the connection response information transmitted by the first data communication entity Afterwards, the connection relation between the first data communication entity is established.
Specific first data communication entity establishes the specific method of connection with the second data communication entity, specific to wrap It includes：
The first data communication entity is according to second number in the authorization message of the second data communication entity Communication request information is sent to the second data communication entity according to the address of communication entity, when first data communication Entity receives the connection response information that the second data communication entity returns, first data communication in preset time Entity determines that the connection between the second data communication entity is established and completes；
When specific implementation, the first data communication entity is from the authorization message of the second data communication entity, by second After the address of data communication entity parses, according to the address of the second data communication entity to the first data communication Entity sends communication request information.After the second communication entity receives the communication request information, if agreed to and the first communication It is communicated, can be sent and responded to the first data communication entity according to the address of the first data communication entity between entity Information, so as to establish the connection relation of the first data communication entity and the second data communication entity.Otherwise similarly, herein no longer It repeats.
And establish connect during, once the first data communication entity in preset time receive make a call to second lead to Prove to be true after interrogation the connection response information that body is returned, then it is assumed that the first data communication entity is to logical transmitted by the second data communication entity News solicited message is not successfully transmitted away or the second data communication entity and is not affected by transmitted by the first data communication entity Communication request information.At this point, if the second data communication entity is only corresponding, there are one address, the first data communication realities Body still repeats the address according to the second data communication entity, and what is repeated please to the transmission communication of the second data communication entity Information is sought, the connection response information until receiving the second data communication entity.And if the second data communication entity be corresponding with it is more In the case of a address, the first data communication entity can send ground to the communication management low pass of the ERP system of the second enterprise Retrieve information in location.Due in the communication management system corresponding to the ERP system with enterprise, being stored with the ERP systems with the enterprise The corresponding all addresses of system, therefore when the communication management system of the ERP system of the second enterprise receives address inspection , can be according to address search information after rope information, inquiry and the address corresponding to the second data communication entity, and will wherein The forwarding address of second data communication entity is sent to the first data communication entity, i.e., is sent to the first data communication entity anti- Feedforward information.Include in address search information：The mark of the address of first data communication entity, the second data communication entity Know, the address for the second data communication entity that the first data communication entity has learned that；Wherein, the first data Communications management system of the address of communication entity for the ERP system of the second enterprise is inquiring the second data communication entity Forwarding address after, be capable of the address of according to first data communication body, by the new logical of the second data communication entity News address is sent back to the first data communication entity；The mark of second data communication entity is for the ERP system of the second enterprise Communication management system carries out the inquiry of the forwarding address of the second data communication entity；What the first data communication entity had learned that The address of the second data communication entity excludes the first data for the communication management system of the ERP system of the second enterprise The address for the second data communication entity that communication entity has learned that, obtain the second data communication entity it is new communicatively Location.
The communication management system of the ERP system of the second enterprise is received in the first data communication entity to the first data communication After entity sends feedback information, the first data communication entity can send secondary lead to according to feedback information to the second data communication entity Interrogate solicited message；Wherein, feedback information includes：The forwarding address of the second data communication entity；Specific acquisition process It is such as above-mentioned.
It is asked when the first data communication entity receives the second data communication entity according to the second communication After the connection response information that information returns, determine that the connection between the second data communication entity is established and complete, and according to The forwarding address of the second data communication entity, to described second in the authorization message of the second data communication entity The address of data communication entity is updated, preserves.
When specific implementation, if receiving the second data communication entity according to secondary in the first data communication entity The connection corresponding information that communication request information returns, it is determined that the connection with the second data communication entity, which is established, to be completed, and is being established After complete connection, the first data communication entity can be preserved its original according to the forwarding address of the second data communication entity The second data communication entity authorization message in the address of the second data communication entity be updated, preserve, under When secondary foundation and the connection of the second data communication entity, it will the forwarding address of successful connection is established using this.And Once believe in preset time again without the connection response for receiving the second data communication entity and being returned according to the second communication request During breath, the first data communication entity can send address search again to the communication management system of the ERP system of the second enterprise again Information, and the feedback information according to transmitted by the communication management system of the ERP system of the second enterprise, lead to for the third time to the second data It proves to be true after interrogation body and sends communication request information, until connection is successfully established.
It should be noted that above-mentioned built the first data communication entity and the second data communication entity are according to institute The authorization message of the first data communication entity and the second data communication entity is stated, the connection established is unidirectional company Connect, i.e., when the first data communication entity need to the second data communication entity send business datum when, established with Being connected between the second data communication entity can be used in the first data communication entity and send industry to the second data communication entity Business data.And once the second data communication entity is wanted to send business datum, it is necessary to which its active is built to the first data communication entity Stand on the connection between the first data communication entity.
