The accompanying drawing explanation
Figure 1 shows that the service chart of corresponding operation flow module.
Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of model for business development provided by the invention is described in detail.
In the following description, a plurality of different aspects of the present invention will be described, yet, for those skilled in the art, can only utilize more of the present invention or entire infrastructure or flow process to implement the present invention.For the definition of explaining, set forth specific number, configuration and order, but clearly, in the situation that do not have these specific detail can implement the present invention yet.In other cases, in order not obscure the present invention, for some well-known features, will no longer be described in detail.
Model has been people for convenience of research, understand and solve the variety of problems that exists in objective event and word, icon, symbol, relational expression and the entity apperance after thinking repeatedly is abstract described to objective reality set, to describe a kind of visualize form of the objective things of being recognized.
Business model is the needs from IT application in enterprises, and a kind of system of doing for business and the administrative institute of enterprise is abstract and describe, and the design and development that the business model system is infosystem provides scientific and rational guiding and foundation.
Business model just is based on Enterprise Engineering Theory and business model system, analyzes, designs, exploitation and maintenance information system.The process of business model, be reality and the knowledge from business and management, and foundation and with reference to the business model system adopts the business model instrument, designs and construct relevant business model resource, and the business model resource is the major product of business model.
The application's service application model comprises: business logic modules, for the definition of storage service logic; The operation flow module, for the definition of storage service flow process.
Wherein, business logic modules for writing service logic, generally comprises three submodule: action(definition action and procedure), the realization of code(service logic, generally use java to realize, src is arranged, dsrc, lib) and the fn(function definition).
The application's operation flow is based on operation flow definition and the operation architecture of PetriNet principle, and PetriNet is the theoretical system that is widely used in now operation flow description and executing arithmetic.Only have three fundamental elements in PetriNet, they are respectively the Place(containers), Activity(processes) and the Token(token), the basic principle of PetriNet is all around these three element definitions, they respectively: Place is used for depositing Token; Activity is used for consuming the Token in its input Place, and produces new Token to the Place of its output; Activity and Activity can not direct interconnection connect, and can only interconnect by Place.The condition that Activity activates is, in all Place of its input, Token is arranged.Just do not had after a Token is consumed by an Activity, can not be consumed again.
Although the application the operation flow system be based on the PetriNet principle, due to business model layer encapsulation, can't touch too much the thing of bottom PetriNet in actual Business Process Modeling process.So here just no longer PetriNet has been described in detail, the details of concrete PetriNet refer to the professional document relevant to PetriNet.
Figure 1 shows that the service chart of corresponding operation flow module.Operation flow passes business form in essence exactly between the people, and the medium approach of being responsible for the transport service list and notifying the other side to be processed is Pending tasks.So in the operation flow system, Pending tasks is key foundation, as long as be operation flow or collaborative involve the transmission of business form between the people and all will rely on Pending tasks.Understanding based on above and consideration, the operation flow system is to take Pending tasks as core, in conjunction with operation flow and collaborative operation flow system.
Wherein, the operation flow module is divided into three parts, and they are respectively the operation flow definition, operation flow operation and orchestration instance (operation flow control data).Whole process and the various rule of operation flow described in the operation flow definition, from use, says that the process flow diagram of picture and the flow rules of setting are exactly the operation flow definition.The core of operation flow operation is business process engine, and it resolves the operation flow definition, advances the operation of operation flow, and the result of operation is exactly orchestration instance.An operation flow definition is moved and is once just produced an orchestration instance, comprises some Pending tasks in orchestration instance.
Wherein, what operation flow definition was described is that enterprise realizes that a business objective (business approval) need to comprise how many link steps, between each link step before and after order and synchronized relation, whom each step the information such as process by.Be abstracted on business model, the corresponding service link of step, ordinal relation is by connecting the arc definition, the corresponding executor of handler, processing requirements corresponds to processing rule, so the operation flow definition is by link, processing rule and be connected the arc composition.
Be drawn in the service link on process flow diagram in business procedure, the mode of operation flow of usining is moved as entrance with Pending tasks.This type of service link need to, after the executor receives Pending tasks, just can move service link by opening the processing Pending tasks.The definition that this type of service link is refered in particular in the operation flow definition, the service link be not drawn on process flow diagram comprised in business procedure is all static service link, they are not included in the category of operation flow definition.
Wherein, the operation flow link is the most most important component in operation flow, and it is described in operation flow needs the artificial processing participated in, the selection in path in processing and operation flow automatically, branch and merging etc.The various rules and the condition that it should be noted that all operation flow link definition all only work when operation flow is carried out the query action.
Wherein, the executor of operation flow rule definition operation flow, the information such as the Treatment Options of various operations and notice.In order to support complex business process, all operation flow rules all can arrange many, in the operation flow operation, according to the effective term arranged and putting in order of rule, calculate a unique rule come into force.The operation flow rule that is to say same type only has unique one can come into force at synchronization.
The calculating of operation flow rule is general all calculates when calling the relevant business action of query, during calculating, according to the order of operation flow rule definition, calculates one by one, when finding one can come into force and just no longer down calculated.The operation flow rule comprises following a plurality of example rules.
Setup rule
Setup rule be defined on operation flow when calling startProcessQueryAction action launching operation flow, for the orchestration instance data are done initialized rule definition.Generally do the title of some flow instances in setup rule, the initialization of binding hours, but setup rule can be to all assignment that concern of the concept SA_Task under orchestration instance in fact.Setup rule only comes into force when calling startProcessQueryAction, and in process flow operation, has just no longer worked later.So be can automatically not follow change here when operation flow business datum value in service changes, and can only write code, initiatively go to refresh.
Notification rule
Notification rule is for having done certain operation and need to notify relevant people the time when operation flow in the process of moving.Define the information such as notify recipients, recipient's processing mode in notification rule.Be to come into force according to some other operations of operation flow level when notification rule is defined in operation flow from it, and be just to come into force according to other certain operations of loose collar assistant warden when notification rule is defined on the activity link.
Executing rule
Executing rule is for the executor of definition of activities link, the optional scope of executor, the information such as Pending tasks attribute and processing mode.Executing rule is done when (and only doing the circulation action) inflow current active link is moved in circulation and is worked in other links, and after giving current active link calculating executor and having generated Pending tasks, executing rule has just no longer worked.
The circulation rule
Operation flow is in service will flow to next step after certain activity link is disposed, and is circulation.As the term suggests the circulation rule is exactly the rule come into force when the current active link is done the circulation operation, the circulation operation that this comes refers to the advanceProcessQueryAction action.Its definition be that the current active link is called advanceProcessQueryAction some options in when action, such as whether needing to eject circulation dialog box etc.It should be noted that circulation is which link and to be which executor is come by the executing rule of the relation between link and next step activity link fixed to next step.
Backoff rules
Operation flow is in service can not be continued for a certain reason to send out in certain activity link and flow to next step, and need to send back to that previous step processes again, is both rollback.As the term suggests the rule that the circulation rule comes into force exactly when the current active link is done rollback operation, the rollback operation here refers to the backProcessQueryAction action.Its definition be that the current active link is called backProcessQueryAction some options in when action, such as whether needing to eject circulation dialog box etc.It should be noted that, rollback operation is that Pending tasks is issued to the once activity link of process again, so give the activity link of process once generate new Pending tasks according to being no longer the executing rule defined on these activity links, but these activity links were used for the Pending tasks of circulation originally.Whom Pending tasks once process just new Pending tasks to be issued to whom by, and execution pattern, some attributes such as contention mode all from old Pending tasks direct copying in new Pending tasks.
Forward rule
The executor of operation flow certain activity link in service can't determine how to process, or needs that first Pending tasks is issued to other people and look at and then process and be forwarding.Forwarding rule is exactly the rule come into force when the current active link is done the forwarding operation, and the forwarding operation here refers to the transferTaskQueryAction action.Its definition be that the current active link is called transferTaskQueryAction some options in when action, such as whether needing to eject circulation dialog box etc.Forwarding and circulation are distinguished and are, circulation is Pending tasks have been issued to the executor of next step activity link, and current active link and the executor of operation flow have become.Although given other executors Pending tasks stream and forward, the current active link of operation flow does not change yet.Forward regular attribute configuration and executing rule one touch the same, so forward the details that regular details please refer to executing rule.Refer to.
Merge rule
Merge rule and be the relation that is defined in the AND merging between a plurality of inputs that are used for describing the AND merging.Merging rule is in the activity link merged at all AND of being directly inputted to, as long as when any activity link is done the circulation operation, it all can work.
Branching rule
Merge rule and be the relation that is defined in AND branch between a plurality of outputs that are used for defining AND branch.Branching rule is to work when AND divides the activity link of supporting the front to do the circulation operation.For example after the AND branch after certain activity link, 3 activity links are arranged, want to accomplish that wherein 2 activity links are to select when this loose collar throttling turns, it is fixed whether remaining 1 activity link is selected by user oneself.In branching rule, describe, the self-determining activity link of user is optional output, and remaining is exactly essential output.
Wherein, for the operation flow executor, operation flow is exactly Pending tasks passing between according to set order and rule between different people in essence in fact, so whether operation flow can combine closely with organizational structure, is to weigh the whether available large standard of operation flow.
Operation flow realizes that by the mode of organizational structure's function, in operation flow and institutional tighter integration, using-system mechanism group of functions becomes organizational structure's expression formula, is used for selecting the complicated arbitrarily scope of organization as the operation flow executor.Simultaneously general expression formula function also can intert for organizational structure's expression formula, has realized that operation flow can obtain the executor from any place.Operation flow executor defines and is used at present executing rule, notification rule and forwarding in rule, and executing rule is used for the executor of definition of activities link, and notification rule is used for defining notification receiver, forwards rule and is used for the recipient of definition while forwarding.
The difference of executor's function and other generic function maximums is the form of rreturn value, and the rreturn value type of executor's function must be the list of specifying the organization unit of type (OrgUnit).Organization unit is to come together to describe by FID and two signs of FName.
Executor's function essence is exactly to select the organization unit of various conditions in fact.Itself also not only can be used executor's function in operation flow, in other with good grounds conditions of system, selects the place of organization unit to use by direct call function or the mode of calling expression formula.The rreturn value of other generic functions, as long as mate with the input parameter of executor's function, just can directly be used as the parameter of importing into of executor's function and use.
Wherein, often need to write some codes and be used for the service control process flow operation in the practical business demand, or, according to the operation result synchronous service data of operation flow, What is more by code is the characteristic that realizes that some operation flows are not supported originally.And the point of penetration of writing these codes is exactly event.
The operation flow event is exactly the event that operation flow is provided by the business action provided in fact.It not only comprises these events that are listed as below, can also give action expansion event arbitrarily.
The operation flow event can define on business procedure, also can on service link, define.Their trigger sequence is the event that first triggers the business procedure higher level, the event on rear triggering service link.
Wherein, the essence of operation flow operation is exactly to realize the business action of miscellaneous service flow process in fact, and its most crucial part is based on the business process engine of PetriNet principle.Architecture, business process engine and business action are without any relation, business action is the extraneous a kind of approach that is used for the service control flow engine just, cast aside the business action, the external world equally can also be as the general Java interface various interface of using business process engine provide the same as class and class are provided.
Business process engine realizes two large characteristics, the firstth, resolve and the computing service flow definition, and then generate ProcessControl.The secondth, realize actual operation flow operation according to ProcessControl, and generate the orchestration instance data and deposit database in.So the essence of business process engine is exactly to resolve the operation flow definition then to generate and maintenance service flow instance data, this is also the essence of operation flow operation.
Wherein, in orchestration instance, the business process engine in the operation flow operation frame (ProcessEngine) is resolved the operation flow definition, and the result of its operation generates orchestration instance exactly.Orchestration instance is a general reference, and it has really comprised the two-part data of task (Task) of flow instance (ProcessInstance) and each activity link in fact.Wherein flow instance (ProcessInstance) is to start flow process to generate one at every turn, and the task of activity link (Task) is each circulation, when rollback and forwarding, all can generate for flowing to the activity link.So they are relations that a flow instance (ProcessInstance) comprises a plurality of tasks (Task).
Because most attributes of flow instance (ProcessInstance) and task (Task) are all the same, so, in database, they are all to be deposited into task list (SA_Task).Two kinds of data are used SCATALOGID and the incompatible differentiation of SKINID field groups.So flow instance (ProcessInstance) is also task (Task) in essence, a kind of task of specific type (Task).
Finally it should be noted that, above embodiment is only in order to describe technical scheme of the present invention rather than the present technique method is limited, the present invention can extend to other modification, variation, application and embodiment in application, and therefore thinks that all such modifications, variation, application, embodiment are in spirit of the present invention and teachings.
