The business scope of big data exchange includes big data asset trading, the design of big data financial derivative data and related services; Development of technologies such as big data cleaning and modeling; Financial leverage data design and services related to big data; Other businesses related to big data transactions approved by regulatory agencies and relevant departments. The Big Data Exchange will provide data futures, data financing, data mortgage and other services for data providers, establish a credit evaluation system for the data of both parties to the transaction, increase the traffic of data transactions, and speed up the flow of data. Data varieties include twelve types of big data: government, medical care, finance, enterprises, e-commerce, energy, transportation, commodities, consumption, education, social interaction and society.
Data trading center is abbreviated as EDI. It mainly forms the message data format of structured transaction processing according to a recognized standard, and then transmits these structured message data from the computer to the computer at the other end through the network. The so-called EDI should include the following three basic aspects:
1, an application field that needs information exchange, namely the environment of EDI. For example: international trade, domestic trade, hospital work, library work, project management and so on. It defines where information needs to be transmitted and between places.
2. The process and rules of information exchange, that is, the process of EDI. It reflects the business process and the accompanying information flow in the actual field. For example, in the process of trade, from inquiry and quotation to payment and delivery. It involves suppliers, buyers, banks, transportation companies, insurance companies and other enterprises (or roles), and it needs to realize dozens of information exchange services. In practical work, this process is embodied in a series of rules and standards.
3. Means of information exchange, including hardware equipment, communication equipment and software, namely the technical realization of EDI. Computer equipment and communication equipment have become more common, and there is no special requirement for the application of EDI. Generally speaking, no special development is needed. For example, communication lines can be solved in various ways, from the simplest telephone lines to renting satellite lines. What is needed is software development. For the application in a certain field, it is necessary to have a set of special software that meets a certain standard. Solving the problems in this field is a technical task.
In a word, EDI should be fully recognized and understood, not only from the perspective of technology, but also from the perspective of hardware.
