Abstract

The embodiment of the invention provides a storage model conversion method and device, which can be applied to a server. The server includes a raw database and a temporary database; a storage model of the raw database includes a nested storage model; a storage model of the temporary database includes a two-dimensional table storage model. The method and the device can covert data stored in a non-relational database into data which can be directly used by a user in a relational storage model; and the method and the device further can convert data of the user which needs to be stored in the relational database storage model, into data stored in the non-relational storage model, can utilize the advantages of non-relationship storage, and can achieve easy access and storage.

Description

Technical field [0001] The invention relates to the field of databases, in particular to a storage model conversion method and device. Background technique [0002] With the rapid development of Internet technologies such as cloud computing and social networking, the amount of network data is growing at an extremely fast rate, with flexible data and diversified data types. In order to analyze and utilize these huge data resources, we must rely on effective data management techniques. Traditional relational database technology has encountered huge obstacles in data processing, system scalability, etc., and is unable to handle large-scale data storage tasks. At the same time, the technology of non-relational database NoSQL (Not OnlySQL) has developed rapidly. Because of its non-relational, distributed, open source and horizontal expansion characteristics, it is an effective way to effectively solve big data storage and analysis. [0003] The emergence of big data has brought new ch...
