4 Overall framework of exchange
Framework basis
Based on GB/T21062.1-2007, under the framework of the public data exchange platform of the national e-government external network, this standard stipulates the various elements in the overall framework of the exchange of the national credit information sharing platform. Exchange node
Exchange node refers to the system unit that realizes the transmission and processing of information resources in different business systems under the national credit information sharing platform, which is divided into two categories: end exchange node and central exchange node (national exchange node). The public credit information exchange nodes stipulated in this standard are: national credit information sharing platform, national department credit information system, provincial credit information platform, etc.
3 Exchange domain
4.3.1 Exchange domain composition
The exchange domain stipulated in this standard is the public credit information exchange environment composed of the national credit information sharing platform, national department credit information system, provincial credit information platform, etc. 4.3.2 Central exchange node
The national credit information sharing platform is the central exchange node of the exchange domain, also known as the national exchange node. 4.3.3 End Exchange Nodes
The national department credit information system, provincial credit information platform, etc., as the end exchange nodes of the exchange domain, directly exchange information with the national credit information sharing platform.
Exchange Model
4.43
4.4.1 Exchange Model Composition and Function
The public credit information exchange model consists of exchange information, exchange relations, exchange services, and shared information bases. Information exchange can be carried out through the shared information base or through the central exchange node. The public credit information exchange model is shown in Figure 1. End exchange node

End exchange node
As the central exchange node, the national credit information sharing platform manages the information interaction services of the end exchange nodes in the exchange domain, provides point-to-point and point-to-multipoint information routing and reliable information transmission, and forms the national credit information database according to demand. As the end exchange node of the exchange domain, the credit information system of each national department is responsible for receiving and aggregating the information of vertical departments, completing the conversion operation between the vertical business field information and the exchange information, and realizing the transmission and processing of the exchange information through the exchange service, and at the same time forming the credit information database of the department according to demand.
As the end exchange node of the exchange domain, each provincial credit information platform is responsible for receiving and aggregating information from government departments within its jurisdiction, completing the conversion operation between business information and exchange information, and realizing the transmission and processing of exchange information through exchange services, while forming the provincial credit information database according to demand.
4.4.4 Exchange Service
The exchange service is a set of operations for the exchange node to transmit and process credit information resources, and a specific embodiment of the exchange method. Each exchange node should deploy an exchange service.
4.4.5 Shared Information Library
The shared information library is a centralized storage area for public credit information resources that can provide consistent public credit information resources for multiple end exchange nodes. Any end exchange node can access the shared information library according to certain rules. In the exchange system, the shared information library is optional. 3

5 Exchange methods and interface requirements
5.1 Exchange method requirements
Information exchange should adopt three exchange methods: file exchange, database docking, and service call. a) File exchange is to transfer data files through reliable file transfer services. A large number of data records require the use of XML files, EXCEL files, and TXT files for transmission, and the data provider node is required to provide the file format and data resource description. The database docking method is the data exchange from library to library. It is required that each end exchange node provide a table building script to the central exchange node (for b)
the central exchange node to establish an equivalent structure table), and import the exchange information into the database of each exchange front-end machine, and use the transmission service to realize the exchange from library to library. At the same time, it is also required that each end exchange node provide the database service IP, database instance name, user name, password, and database building script.
c) Real-time access or transmission of a small amount of data requires the use of a service call method to access or transmit the credit information directory and data records through the WebService service interface.
2 Data exchange requirements
Data exchange should comply with the following:
a) In the exchanged data, Chinese characters use Chinese half-width, and English letters, numbers and symbols use English half-width. b) Data exchange should be encoded in UTF-8 format. SZIC
c) For file exchange and database docking, the data provider needs to add two data items for each exchange data record: record ID (GUID) and record database time. Among them: record ID is the data record fingerprint, which is assigned by the original record generation unit and uses the GUID mechanism to identify the global uniqueness of the record. It is the information primary key of each credit information. For the file exchange method, the record database time refers to the time when the data is transferred to the file; for the database docking method, the record database time refers to the time when the data is loaded into the database of the front-end machine of the end exchange node. 5.3 Exchange interface classification
5.3.1 Interface type
The public credit information exchange interface has two types: data reporting and data sharing. 5.3.2 Data reporting class
The data reporting class interface refers to the end exchange nodes such as the credit information systems of various national departments and provincial credit information platforms reporting credit data to the national credit information sharing platform.
5.3.3 Data sharing class
The data sharing class interface refers to the end exchange nodes such as the credit information systems of various national departments and provincial credit information platforms sharing and retrieving credit information data in the national credit information sharing platform. 5.4 Data exchange mechanism
The exchange node data exchange mechanism is shown in Figure 2. 4

The main process of the data reporting exchange node reporting data to the data receiving exchange node includes: GB/T39443—2020
Account reconciliation
Database table
Get feedback
Data generation: According to the agreed reporting cycle, the data reporting exchange node generates the data to be transmitted a)
according to the requirements of this standard, as shown in ① in Figure 2. The starting time and reporting cycle of the reported data can be agreed upon in the work rules. When the data transmission exchange node is an end exchange node and the data receiving exchange node is a central exchange node, the initial transmission should be the full data set transmission, and then incremental transmission.
Data transmission: The data transmission exchange node transmits data to the data receiving exchange node through a reliable data transmission service. The data transmission service should be able to support breakpoint continuation and require the record of the successful transmission mark, as shown in Figure 2②. Data confirmation: When the data receiving exchange node receives the data transmitted by the data transmission exchange node, it should confirm the content of the data c)
(see Table 1 for specific content), as shown in Figure 2③. Get feedback: After the data receiving exchange node confirms the received data, it generates a reconciliation database table d)
record according to the content of Table 1, and feeds the record back to the data transmission exchange node, as shown in Figure 2④. e)
Reconciliation confirmation: When the data reporting exchange node receives the reconciliation database table record sent by the data receiving exchange node, it should reconcile and confirm the record content (see Table 1 for specific content). If the confirmation is correct, the data transmission is successful. If there is an error in the reconciliation, the data transmission fails and needs to be retransmitted, as shown in Figure 2.
