Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the application.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the application.
Currently, it is synchronous for the data between heterogeneous data source, lead to produce and be realized using DataX frame, DataX conduct itself
Synchronizing for different data sources is abstracted as the Reader plug-in unit that data are read from source data source, Yi Jixiang by data synchronization framework
The Writer plug-in unit of data is written in target side, and theoretically DataX frame can support the synchronous work of the data of arbitrary data Source Type
Make.
But when stating method in use and realizing that data between heterogeneous data source are synchronous, for the database of different frameworks,
The corresponding reading plug-in unit of secondary development and write-in plug-in unit are needed, versatility is poor.
In order to solve this technical problem of poor universality, present applicant proposes carry out heterogeneous data source by software robot
Between data it is synchronous.
Wherein, software robot, that is, agent, agent have independence, interactivity (i.e. social), reactivity and active
Property.Agent has the computing resource for belonging to its own and part in the behaviour control mechanism of itself, can be no extraneous direct
In the case where manipulation, according to its internal state and the environmental information perceived, it is resolved that and the behavior of control itself.Such as SNMP
In agent be exactly independent operating in managed unit from host process.Agent can be used with other Agent (including people)
Agent communication language implements flexile interaction, can effectively cooperate with other Agent.Such as one
User on Internet needs to state information requirement to the Agent that takes the initiative in offering a hand using Agent communication language.Agent can feel
Know locating environment (may be physical world, the user at manipulating graphics interface, or other Agent etc.), and dependent event is made
Reaction in due course out.Such as the Agent of a simulation aircraft can make in due course reaction to the manipulation of user.Agent can be followed
Promise is taken the initiative action, and object-oriented behavior is shown.Such as the Agent that takes the initiative in offering a hand on an Internet, it is obtaining
Obtain the user that information newly can actively be submitted to needs according to agreement later；One Workflow Management Agent, can be by
Newest job progress is actively notified to related work station as agreed.
Message passing mechanism between Agent is realized by the processing of message event.Assuming that Agent A has message event
Processing capacity, receive service request typical operation it is as follows: a service request for passing to A leads to message event
Generation.(message) the event perception device of A will detect in time the generation of the event, to cause (message) event adapter of A
Receive this message；For message event adapter according to the messaging protocol between Agent, analysis identifies that the message is service request
Type, and then cause (request) event handling distributor of A, and related Adapted information is submitted into the distributor；(request) thing
Part handles distributor and then selects corresponding method of servicing to execute according to Adapted information.
