Description
Technical field
The invention belongs to field of computer technology, relate to dynamic integrity development platform, can be used for the integrated exploitation of various systems, the system that particularly integrated demand constantly changes based on Agent.
Background technology
The system integration is to reuse existing Legacy System, solves process interconnected between various systems, interoperability issue.There is numerous system integration modes at present, mainly contains traditional system integration scheme (comprise Integrated Solution, based on the middleware Integrated Solution, based on distributed integrated Integrated Solution), based on the system integration scheme of Agent based on the systems programming interface.These system integration schemes have satisfied the integrated demand of existing system substantially, and in following a period of time, they will be as the main means of the system integration.
1. traditional system integration scheme
(1) based on the Integrated Solution of systems programming interface, the DLL (dynamic link library) that is to use the subsystem that is integrated to provide is made integrated main points, realizes that end-to-end system is integrated by hand.Keeping under the constant prerequisite of original system architecture, the developer will be responsible for making up the unified systems programming interface accessing platform of a cover, and the data structure of particular subsystem is shone upon, is converted to exploitation to visit the customization application of each subsystem data with it; As requested these data are operated, and it is committed to target sub system.Because this platform has been integrated the disclosed DLL (dynamic link library) of system, can control and visit the data and the process of each subsystem easily.This scheme is applicable to the system of the large-scale encapsulation character that comprises complicated applications logic and external data base metadata.But this scheme realizes that integrated complexity is bigger, along with the increase of integrated demand, realizes integrated and costs such as the manpower that consumes, fund are also constantly soaring, finally can reach and make us unacceptable stage.And the integrated degree of total system is subject to the api interface that original system provides.
(2), be to utilize the adapter that provides in advance to obtain the private data format of system applies, and realize data-switching by mapping, conversion and transmission mechanism that middleware platform provides based on the middleware Integrated Solution.Middleware platform can also provide simultaneously the support scheme at affairs exchange, incident supervision, error trap and security feature, can provide in hiding systematic procedure complicacy subsystem funcall to greatest extent, thereby realize integrated.This Integrated Solution has been avoided a large amount of program coding work, and will be reduced to bottom line to the degree of understanding of breakpoint working method, but is not to be applicable to all situations, and its cost is high, complex structure and lack versatility.
(3), be to use popular Web Service and XML technology based on the Integrated Solution of distributed computing technology.The developer does not need to understand the interface that becomes of various different sub-systems uses, in this development mode, which no longer comprises need be by programming mode establishment and the addressable port of answering with tight association, on the contrary, information is separated and can be exchanged in any internal applications from information source.In implementation process, avoided each subsystem to carry out base layer encodes based on the Integrated Solution of distributed computing technology, need not to understand its internal processes logic, but when the integrated demand that is integrated system changes, still needed to carry out a certain amount of recompile being integrated system.
2. based on the system integration scheme of Agent
(1) the Telescript system is the system based on mobile Agent of first commercialization, and total system adopts the Telescript language to finish, and a kind of solution of mobile Agent is provided for e-commerce transaction.The Telescript system is by the mobile of Agent and calculate data and the information interaction of finishing in the commercial activity.It is except having the Software Agent fundamental characteristics, also has movability, can on network, independently move to another main frame from a main frame, replace the user to finish the task of appointment, this computation schema reduces the offered load in the Distributed Calculation effectively, improved communication efficiency, the dynamic network environment that has changed that adapts to has good security and fault-tolerance.
(2) Aglet is by the mobile Agent technology of IBM Corporation with pure Java exploitation, and practical platform---Aglet Workbench is provided, and can be used to exploitation or carries out the mobile Agent system.Aglet is the Java applet object with Agent behavior.Aglet is resulted from the machine with the form of thread, can suspend the work of execution at any time, and then whole Aglet can be dispatched on another machine, restarts hanging up of the task of then carrying out again.Communication between the Aglet adopts the mode of message transmission to come the pass-along message object.Based on security consideration Aglet is not to allow its information of extraneous direct access, provides corresponding interface to link up with extraneous but see through an agency.
(3) JADE (Java Agent Development Environment) is a mobile Agent system that writes with Java, can be used for developing the application based on Agent.The example of the JADE execution environment of each operation is called as container, i.e. the environment of Agent operation.An independent special primary tank must be in state of activation, and every other container all must be registered to primary tank.In JADE, Agent is a kind of entity with cooperation and communication capacity of autonomy.The JADE platform only provides the running environment of Agent, guarantees that Agent thereon can normally move.
(4) the synthetic framework ABFSC (Agent-Based Framework for SoftwareComposition) of the software of Zhejiang University is an integrated system framework based on Agent and component technology, the description of cooperation and semantic interoperability between the design of back-up system architecture, the promotion software component.This system proposes based on the software of knowledge synthetic, and provides certain means to describe semantic interoperability between software component.ASFSC emphasizes based on the software of knowledge synthetic, describes cooperation and semantic interoperability between the software component, has improved the present situation that existing software component/flexible bus technology lacks system flexibility.
Above-mentioned several Agent system is emphasized the movability of integrated framework and Agent, and the new Agent system newly developed that attaches most importance to provides the support of instrument and running environment, but does not consider the support of reusing and system requirements being changed to Legacy System.
Though above-mentioned traditional system integration scheme has solved interconnected between different system, interoperability problem, has realized the problem of reusing of Legacy System, it lacks the expandability of certain autonomy, intelligent, dynamic and domain-oriented.Existingly features such as the autonomy, initiative of Agent, social, intelligent and movability have been utilized based on the system integration scheme of Agent, make system after integrated have the expandability of certain autonomy, intelligent and domain-oriented, but existingly can not adapt to the variation of integrated demand flexibly, realize the dynamic integrity of system flexibility based on the system integration scheme of Agent.
