Data exchange this noun, listening for a long time, do not know its exact meaning and standard, online search search, there is no clear result, but see an EDI noun.
EDI is an abbreviation of English Electronic Data Interchange, and Chinese can be translated as "electronic data exchange", Hong Kong, and Overseas Chinese people called "Electronic Data Unicom". It is an electronic means of transferring orders, invoices, etc. It uses a computer communication network to trade, transport, insurance, banking and customs and other industries, with an internationally recognized standard format, to achieve data exchange and processing between relevant departments or companies and enterprises, and completed trade as The whole process of the center is a novel electronic trade tool developed in the 1980s, which is a combination of computers, communications, and modern management technology. The International Standardization Organization (ISO) describes EDI as "to" trade trade (commercial) or administrative transactions into structured transaction or information data format, from computer to computer electrical transmission. ITU-T (original ccitt) defines EDI as "structured transaction data exchange between computers to computers". Also because EDI can reduce the paper file files during trade, EDI is also known as "paperless trade".
It is not difficult to see from the above EDI definition that EDI includes three aspects, namely computer applications, communication, network, and data standardization. The computer application is the condition of EDI, the communication environment is the foundation of the EDI application, and standardization is the feature of EDI. These three aspects are connected to each other, interdependent, and constitute the basic barrier of the EDI. The EDI system model is shown in Figure 1.1.
It seems that a real data exchange platform should be sure to support such formats.
Google, there is some company claimed by the data exchange platform, most up, moving out XML, data exchange, Wang Wensheng, is the interaction between the heterogeneous system. Death programming should also be said, of course, the platform always has some automation, Shenzhen has a company's practice is the source and target of Xmlscheme, and the source and target of the customer customized data exchange, the interface is like Xmlspy mapping Function, anyway, I was completely dizzy, but it was a strategy, but also made a Scheme for several databases to describe the database data source. For files, it is relatively simple to complete FTP.
Some companies are also promoting, of course, I have not seen more detailed explanation.
Sybase also has a DXP, honest in his white paper, directly indicating something for China's e-government, no fine, should be a log-related, similar to the synchronization between the heterogeneous database.
However, there is still a problem. Data exchange in reality may be much more, it is uncertain, which may be more uncertain, these are the duties of the data exchange platform, if so, it is more painful.
If any of what is the real data exchange platform looks like, give some information, thank you first.
