However, it is known that the key business data stored in the traditional database system (relational database, document database, in-memory database, etc.) by the enterprise has the following problems:
data authenticity and integrity issues. The traditional data management technology based on the database is easy to be attacked from the outside, can be modified, deleted and covered by lawless persons, and can change the authenticity of the data by only needing a few simple instructions and spending very little time. One may risk the collar if more overt or covert benefits can be brought about because of data tampering. Because of this, the authenticity of the critical business data itself stored within a traditional database system is unknown, and erroneous decisions may be made based on data whose authenticity is unknown, causing significant losses.
The availability of data. In order to solve the operational risk of the single-center database system and reduce or eliminate the influence of shutdown on service availability, enterprises generally build data centers according to a 'two-place-three-center' mode. The mode improves the business continuity of enterprises to a certain extent, but because the occurrence probability of a disaster is very low, disaster recovery facilities are basically in an idle running state, and the operation cost is high. Secondly, the switching between the main center and the standby center needs a long time, and the service may have an interruption risk. Meanwhile, because the technology of cross-center database clustering is not mature, and the construction of a double-active database system is high in cost and difficult to maintain, the construction of a multi-active database is a well-recognized technical difficulty in the industry.
