Embodiment

As shown in Figure 1, based on the data sharing service system of Internet of Things, this system comprises following 5 layers successively:

Infrastructure layer comprises network infrastructure, storage server, intelligent terminal, and it provides a hardware foundation platform for whole service system; Said intelligent terminal is that automatic identification equipment is different according to the service function of each subsystem; Comprise rfid interrogator, bar code read write line, bio-identification device; Through information sensing equipment such as radio frequency identification (RFID), infrared inductor, global positioning system, laser scanners, the agreement by agreement is connected article with the Internet; Carry out information exchange and communication, to realize intelligent identification, location, to follow the trail of, monitor and management;

Data Layer; Former data and types of applications data to from low layer are managed; With extracting from the relevant service logic in the dissimilar intelligent terminals and the code of data access; Be packaged into the data format of standard, it provides a data collection and data interchange platform for whole service system; The heterogeneous database of said data Layer comprises Oracle, SQL Server, DB2, Access etc.;

Service layer and Service Component layer, service layer has stipulated the interface of application layer transfer service, the Service Component layer is specifically realized service under the prerequisite of the service interface of following service layer's regulation; The service that said service layer provides is divided into two types: one type is business service intrinsic in the enterprise, like personnel, vehicle room entry/exit management, concerning security matters bearer services logic, vehicle management business service, the service of access control and attendance service logic, the service of night watching service logic etc.; Another kind of is the service that system normally moves to be needed, and mainly comprises authentification of user service, data access service etc.

Application layer is user oriented operating platform, and system and user carry out mutual interface, to the user friendly man-machine interface is provided, and is that user and system carry out mutual unique interface.Said application layer mainly comprises according to different its functional modules of service function of each subsystem: system modules such as warehouse handling of goods and materials, fixed capital management, concerning security matters management, personnel's vehicle room entry/exit management, attendance management, patrolling management.

In the above-described embodiments; Notebook data share service system adopts Web Services technology to realize; Web Service is made up of ISP, service register center and three roles of service requester and issue, discovery and three operations of binding; The ISP defines the service describing of Web Services; And being published to service requester or service register center to it, service requester uses finds that operation comes from this locality or the service register center retrieval service is described, and uses service describing and ISP to bind and call Web Services realization or synchronous interaction then.

In the above-described embodiments, notebook data share service system adopts the middleware pattern to realize data integration, through the data details that provides a unified data logical view to hide bottom in the intermediate layer, visits the database of isomery with unified global data model; Through using middleware Technology; Can between the application program of the heterogeneous database of data Layer and application layer, make up the intermediate layer; Operation to database is all carried out through the intermediate layer; Each heterogeneous database is coordinated in the intermediate layer downwards, and the general-purpose interface of unified data pattern and data access upwards is provided for the application of visit integrated data; The XML middleware mainly is made up of wrapper and middleware two large divisions; Wrapper is responsible for heterogeneous database mutual, and the packing heterogeneous data source is realized the consistency of operation, the transparency and the location transparency of data access; It is integrated that middleware is responsible for that transformation result is carried out further pattern; Middleware is made up of integrated scheduling unit, service layer and query processor, and the integrated scheduling unit calls the service that service layer provides according to the different messages of system's transmission, generates corresponding middleware global schema and querying condition; Query processor provides the data of heterogeneous database through wrapper according to querying condition; Be embedded in the corresponding global schema, data result is returned to client, finally be implemented to the mapping of middleware global schema.

In the above-described embodiments; Notebook data share service system is for the optimization of heterogeneous database information integration; Introduce global catalog and concerned dictionary; In the process of query processing, utilize buffer memory to deposit the Query Result of user to global view, utilize former data warehouse to preserve the query capability vector of the various data sources of query relation vector sum that DBA provides; Notebook data share service system adopts heuristic to seek the connection of an optimum, sequence is carried out in half connection; Connection, half catenation sequence of from a query tree, finding out an optimum are search problems, and in heuristic search, each node in the search tree is all represented a state of query script; Root node is represented initial state; Destination node is represented dbjective state, the value of all corresponding evaluation function f of each node, and the minimum node of f value is chosen as expanding node; Evaluation function is expressed as f (x)=g (x)+h (x), and g (x) is the cost that is spent to state x from initial state here; H (x) is a heuristic function, is the lower limit that arrives dbjective state cost cost from the x state, and search starts from initial state; Promptly the root node from the expanded search tree begins; Expanding node x promptly is to produce all possible next step connection or semi-connected operations at the x state, and operating in the search tree that each is possible all is the node of x; Each expansion all is from all leaf nodes of search tree, to select the node of the minimum node of f value as next step expansion, repeats this process up to destination node.

As shown in Figure 2, in the above-described embodiments, notebook data share service system solves that the debatable concrete steps of data set are between the cross-platform heterogeneous data source:

(1) gathers the strange land data of database through Web Service;

(2) customize out transformation rule between the heterogeneous database system that carries out data transaction, comprise the system default transformation rule, the related merging of data and table in database and the table is changed realizing;

(3) merge transformation result with the XML stored in file format in client, to make things convenient for user's retrieve data at any time;

(4) the XML file after client is used conversion is retrieved and to its derivation.
