Data sharing method and device

Abstract

The invention, which relates to the technical field of data sharing, discloses a data sharing method and device. The method comprises: a data resource catalog is formed by a first terminal; the firstterminal associates the data resource catalog with data resources in a data source; and the first terminal issues the data resource catalog that is provided for a second terminal for checking and is used for obtaining at least parts of data resources by subscription if needed. Therefore, data sharing flexibility and security are improved.

Description

technical field [0001] The present invention relates to the technical field of data sharing, in particular to a data sharing method and device. Background technique [0002] With the advent of globalization and the era of big data, different units and individuals need to transmit, exchange and share data resources. The exchange and sharing of data resources can be accomplished in a variety of ways, such as publishing data resources on the Internet, creating a sharing platform, and so on. The traditional shared platform construction process generally adopts a central model, that is, the data center collects data resources from the data resource owner in one direction, and usually uses data exchange software to regularly extract data resources to complete the collection of data resources. The collected content includes databases and files. Wait. [0003] However, during the long-term research and development process, the inventors of the present application found that there ...

Problems solved by technology

For example, the security of information is poor, because the data sharing and openness among the information systems currently under construction are mostly completed by extracting data into the front-end database through "data exchange", because the front-end database lacks unified security guarantees , unified access control, low network security level, more and more leaks through the network, and serious data theft

The coordination of information is poor. In the process of traditional data exchange, the administrator of the data center must be familiar with the data standards and business systems of each unit. Due to the serious data standards and data inconsistency of each business system, the data center is facing multiple Communication efficiency is low in the unit

Information sharing is poor. In the process of building an information resource sharing platform, business units generally provide data to the data center in one direction, but data centers rarely share data with business units. Lack of management and control on the safe use of resources, so we are more cautious about data sharing, which also leads to the low enthusiasm of business units for resource sharing
