The on-cloud data exchange system is the smallest constituent unit of a cloud-based data exchange architecture. The main function is to support the realization of data communication between different business departments.
Any one of the provincial departments has its own offline database (or temporary repository) and its own online tenant space. In the cloud framework scheme with the open data processing service, an on-line renting space is borne by a project space (project) distributed to each tenant by the open data processing service, each provincial direct department door is used as a tenant to place own public data in the renting space of the open data processing service, and after a series of approval authorization processes, data collision is carried out on the data with other provincial direct department data in an exchange space and a collision result is obtained.
In the cloud architecture scheme without the open data processing service, the online leased space is provided by other non-open data processing service storage devices, is isolated from each other, and provides an access control service based on the authority, so that the access control service serves as a data access entrance.
The data gateway comprises a data exchange gateway function and an API gateway function, and for the situation that no government departments exist, the data gateway can be deployed in each government functional department to realize data exchange under the cloud. The data gateway provides a heterogeneous bridging function, and the real-time monitoring of the exchange process, the scheduling of the data exchange timing task, the transmission safety management, the intelligent data recovery and the breakpoint continuous transmission of the data are realized.
The data compression encryption can guarantee the channel security of the data in the internet transmission, and the SSL transmission channel encryption and the data compression are provided.
The data exchange gateway can be used for desensitizing data, common desensitizing conversion processing of sensitive fields is supported, such as desensitizing conversion of names, identification numbers, telephone numbers and addresses, customized desensitizing rules are supported, and sensitive information is converted according to actual requirements of users. For the fields with the main foreign key relation and the formula calculation relation, the data exchange gateway can also perform synchronous desensitization on the relevant fields, so that the logic correctness of the service is ensured without being influenced by data desensitization.
If the user's need for data synchronization is frequent periodic, then an incremental synchronization function may be used. The incremental synchronization can avoid repeated redundant data synchronization work, and particularly when the basic data quantity is large, the incremental synchronization function has special advantages. And by matching with the Job periodic scheduling function, only the data changed in the period of the current round can be synchronized each time, and a large amount of time resources and bandwidth resources can be saved. Scenes such as real-time disaster recovery and periodic disaster recovery which have high requirements on time efficiency are also required to have a data increment synchronization function, and the traditional full data synchronization function is not satisfactory in the scenes.
The data gateway can also carry out unified management on authentication, authority management, flow control and the like, so that a large amount of redundancy is reduced, and the API gateway can uniformly realize functions of authentication, flow control, access control and the like.
The data exchange and sharing platform provided by the embodiment of the invention supports three exchange modes of direct exchange, sharing exchange and safe exchange.
The data open sharing platform uses the data integration platform as a data transmission engine to complete the data moving. The data open sharing platform provides rapid data transmission capacity, supports a user-defined transmission plan, can periodically and automatically transmit a data source according to business needs, does not need manual intervention, and reduces the risk of manual execution and labor cost.
The sharing exchange relies on an open data processing service platform, and a special exchange form of data is realized through the characteristics of open data processing service. The process of data exchange is actually the process of authorizing the user in the open data processing service, the data does not need to be moved after authorization operation, the authorized user can directly access the shared data, data transportation between data sources can be reduced, transmission pressure is relieved, and the method is safe, convenient and quick.
If the data that the user wants to obtain is sensitive data of the other party, the aforementioned direct exchange mode is no longer applicable. Therefore, for the purpose of privacy protection, it is necessary to prevent the user from directly touching the original data, and still use the data to perform calculation analysis to obtain the result. The security exchange is created based on technologies such as data protection and resource sharing of an open data processing service project space, controllability and security of the whole exchange process are guaranteed through a whole set of security exchange processes including auditing, deploying, result obtaining and the like, and meanwhile, data does not need to be moved in the security exchange process.
The data exchange and sharing platform provided by the embodiment of the invention comprises a data exchange subsystem and data exchange gateways of all departments, wherein each department has an offline service database or a temporary database and an online tenant space of the department, each department is used as a tenant to place own public data in a renting space, and after a series of approval authorization processes, the data exchange and sharing platform collides with data of other departments in the exchange space and acquires a collision result; the data exchange subsystem is used for providing data directory and data exchange service; the data exchange gateways of each department are used for carrying out data forwarding service and providing data source management, conversion management, data transmission encryption, operation management and user data access API authentication functions, so that data transportation among data sources can be reduced, and exchange and sharing of data resources are realized.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
