Description
Technical field
The present invention relates to a kind of method of active obtaining data from isomery enterprise information system, belong to computer software technical field.
Background technology
Along with the informationization of enterprise, increasing enterprise brings into use infosystem maintaining enterprise data.ERP (Enterprise Resource Planning) enterprise resource planning, WMS (Warehouse Management System) warehouse management system, CRM (Customer Relationship Management) Customer Relationship Management Services, the various enterprise information systems towards different application such as SCM (Supply chain management) supply-chain management system are deployed in enterprise.
But do not have external interface can for sharing data in most business system, this makes the business parnter of user or enterprise cannot obtain information in enterprise information system.
Existing solution can be divided into two classes:
1, the business software company headed by IBM, proposes to integrate multiple infosystem.Realize getting through of internal system data by reconstruct, add and can, for the web interface of external reference, allow user to obtain data.
2, for the Internet of things middleware of AspireRFID, define the data layout mutual with enterprise information system and method, by integrating enterprise information system, middleware and Internet of Things bottom-layer network (as RFID network), allow self reconstruct of business system add interface, thus data are supplied outer access by the interface of middleware.
Correlation technique:
S.Kim etc. propose a kind of store of business events descriptive language, thus complicacy when decreasing Enterprise Information System Integration.But need to learn the definition of other standards during this language owing to using, so bring inconvenience to developer.Y.Liu etc. propose a kind of conformable frame, by integration process being divided into four levels, carrying out modeling, thus improve integration efficiency when integrating according to these four levels.But this framework does not provide unified interface to be user's access.M.Li etc. propose a kind of mode by catching enterprise information system list and integrate, and which decrease the difficulty of integration.But due to the isomerism of list, result in the tight coupling of framework and enterprise information system.N.Leontiadis etc. propose enterprise information system connector, and define concrete mutual message form, thus standardization interactive information.But this still needs to carry out other reconstruct of code level to enterprise information system and integrates.
But these technical methods all need to be reconstructed enterprise information system.Due to the isomerism of enterprise information system, each system has different service logics, implementation method, deployed environment, so use these methods to be reconstructed the financial resource and material resource manpower of meeting at substantial.
Summary of the invention
For the technical matters that prior art exists, the object of the invention is design a kind of active obtaining from isomery enterprise information system and share the method for data: can the enterprise information system of compatible isomery, initiatively from enterprise information system, obtain data, avoid being reconstructed enterprise information system, valuable data can be obtained from enterprise information system, unified access interface is externally provided.
Technical scheme of the present invention is:
From isomery enterprise information system, a method for active obtaining data, the steps include:
1) a daily record watch-dog is set in the enterprise information system selected by each;
2) log information produced in its monitoring journal file is sent to the event manager module of company information shared system by daily record watch-dog described in each;
3) event manager module filters log information, obtains the log information characterizing enterprise information system data variation and business operation, and sends it to the regulation engine of company information shared system;
4) regulation engine is according to setting the event that will generate and the rule of presetting, and mates, determines the value in each territory of event, and send it to the event processing module of company information shared system to described log information;
5) after event processing module receives the value in each territory of event, encapsulation produces Context event, and is sent to by the Context event of generation information server for user's inquiry.
Further, event manager module to the method that log information is filtered is: first event manager module extracts quaternary group information { time, grade, source code class and method, operation information } from the every bar log information received; Then according to the grade of daily record, the source code class of daily record and method, log information is filtered, obtain the log information characterizing enterprise information system data variation and business operation.
Further, described rule comprises: rule ID, rule name, condition, action; Wherein, rule ID is the unique identification of each rule in event manager module, the language that rule name characterizes regular concrete function describes, defining the condition of log information being carried out to rule match in condition, defining in action the subsequent treatment that the log information meeting matching condition is made being detected.
Further, described condition comprises: interval effective time between many log informations, the valid data field in log information, the effective traffic logic in log information.
Further, describedly determine that the method for the value in each territory of event is: from valid data field, extract data by described action, and generate the value in each territory of event according to extracted data and effective traffic logic.
Further, described company information shared system is provided with the regular interface of a declarative status transfer style, and each rule has a Uniform Resource Identifier URI.
Further, described information server adopts relevant database or stores described Context event based on NoSQL database; Described information server is provided with a query interface.
The isomerism of enterprise information system, result through mode that reconstruct adds interface and carry out acquisition of information and shared cost is high, the cycle is long.Because enterprise information system has journal file separately, so we adopt obtain the information in corresponding enterprise information system by the mode of information in parsing journal file.Although the design of daily record is in order to developer carries out the debugging of system, because the information of daily record has following features:

Embodiment
Along with the operation that enterprise personnel carries out in enterprise information system, enterprise information system will upgrade corresponding journal file, and in the middle of journal file, record the concrete operations situation of operating personnel, and the change of corresponding Enterprise Resource.
As shown in Figure 1, designed data capture method of the present invention is mainly divided into three large steps:
1, the monitoring of log information and acquisition: active obtaining data real-time from journal file, corresponding concrete steps 1) and 2);
2, the generation of Context event: the information processing in journal file is generated the Context event with commercial value, corresponding concrete steps 3) ~ 6);
3, information server stores information and provides access interface: store the event information generated, provide the access interface of user's obtaining information, corresponding concrete steps 7) and 8).
Concrete steps are as follows:
1) deposit the path of log information according to enterprise information system and filename monitors corresponding journal file by the daily record watch-dog being positioned at each enterprise information system server end, if there is new log recording to produce in journal file, then read these new records.
2) daily record watch-dog is transferred to event processing module after obtaining the new record of enterprise information system renewal.
3), after event processing module receives log information stream, first coarseness filtration is carried out to log information.Every bar log information can be abstracted into the four-tuple of sign " { time, grade, source code class and method, operation information } ".According to logging level, the source code class of daily record and method, filter the log information obtaining characterizing enterprise information system data variation and business operation.Then this log information is transferred to event manager module.
4) event manager module receive filtration after information, be transferred to regulation engine.Regulation engine, according to the rule set in advance, carries out mating and reasoning, thus determines the value in each territory of the event that will generate, and it is returned to event processing module again.Each " rule " comprising: rule ID, rule name, condition, action, four parts." rule ID " is the unique identification of each rule in event manager module, the language that " rule name " characterizes regular concrete function describes, the condition of log information rule match is defined in " condition ", define in " action " after the log information meeting matching condition being detected, the subsequent treatment that this module is made.Wherein " condition " is main from " intervals effective time between many log informations ", and " the valid data field in log information ", aspects such as " the effective traffic logics in log information " is stated." action " mainly defines " how data in extracted valid data field " and " how generating the value of each field of events according to available data and service logic " wherein, the log information newly produced can mate with strictly all rules by regulation engine one by one.Such as: if we want the logistics information of ERP system certain article central being captured in certain dealer, rule can be created according to the service logic of this dealer's enterprise information system.In ERP system, stocking up of article is generally divided into: purchasing agent creates order; Warehouse keeper upgrades warehouse state; Finance issue invoice, these three steps.If these three steps of article all complete, then prove that this enterprise completes stocking up to these article.Therefore, we can create the rule of event of stocking up about article: " rule ID " is automatically generated by system." rule name " can assignment be " article are stocked up "." condition " can be divided into three sub-conditions in detail: " sub-condition 1 " correspondence identifies that purchasing agent creates the Log log information of this step of order, " sub-condition 2 " correspondence identifies that warehouse keeper upgrades the Log log information of this step of warehouse state, and " sub-condition 3 " correspondence identifies the Log log information of financial this step that issues invoice.Due to the log information certain corresponding different " source code class and method " and " operation information " that as above three steps are corresponding, so by regular expression and identifiable design.In this example, the main value extracting " time " and " article ID " two territories of this event of stocking up of " action " part.The value of " time " equals " sub-condition 3 " finance and to issue invoice time of log information of this step." article ID " from " operation information " that " sub-condition 1 " purchasing agent creates this step log information of order, obtain the order number of these article and Item Number classification generates.
5), after event processing module receives the value in each territory of event, encapsulation produces Context event, and the Context event of generation is sent to information server catch interface.
6) in the process, user can pass through regular interface, changes rule.
7) information server catch interface to event information after, be stored in the middle of data bank.
8), after data are stored into data bank, user by the query interface of information server, can inquire about the information in data bank and subscribe to.
Embodiment is told about for ADempiere.ADempiere is the foremost ERP system of increasing income in the whole world, is widely used by a large amount of enterprise.Along with the operation of ADempiere operates, daily record can constantly upgrade.The log recording of ADempiere is for being divided into 9 grade: OFF; SEVERE; WARNING; INFO; CONFIG; FINE; FINER; FINEST; ALL, can arrange the level condition selecting to generate daily record by the preference in system.For obtaining company information as much as possible, we select ALL to carry out log analysis.Concrete steps are as follows:
1) under the journal file of ADempiere is stored in <%ADEMPIERE_HOME%>/log path.And journal file can be named according to the date, form: " clientYYYY-MM-DD_X.log ", such as: " client2013-05-12_0.log ".The renewal of journal file monitored by daily record watch-dog as described above path and filename, and real-time reads in the new log information produced.
2), after daily record watch-dog gets the new record produced, event processing module is transferred to.
3) after event processing module receives log information, according to logging level, the source code class of daily record and method, filter the log information obtaining characterizing enterprise information system data variation and business operation.Can filter out grade at this is SEVERE; The information of WARNING.Then the log information obtained filtered is sent to event manager module.
4), after event manager module receives data, daily record data is resolved.And carry out according to the rule of writing in advance the information that reasoning generates field of events.Rule sample is as follows:
And the event thresholding obtained after reasoning is sent to event processing module.
5), after event processing module receives the value in each territory of event, encapsulation produces Context event, and the event of generation is sent to information server catch interface.Example message is as follows:
6) the regular interface that in the process, user can write in advance is changed rule.Such as can give each regular Uniform Resource Identifier URI by the interface of declarative status transfer style (Restful), thus be convenient to user's access.
7) information server catch interface to event information after, be stored in the middle of the relevant database in the middle of data bank.
8), after data are stored into data bank, user by the query interface of information server, can inquire about the information in data bank and subscribe to.
