Abstract

The invention provides data storage, query and loading methods and devices. The data storage method includes steps of setting up objects for user data when users store data, wherein the objects include the user data and attribute information thereof, and each object is provided with a corresponding object identifier; storing the attribute information of the user data into a metadatabase, and writing the user data into a corresponding bottom storage system according to the attribute information of the user data, wherein the metadatabase is used for storing correlations of attribute information lists of the attribute information through the identifiers of the object. The data query method includes determining data storage positions to inquire data according to the identifiers of the objects in the attribute information list after receiving query requests. The data loading method includes downloading the data after rectifying the attribute information lists corresponding to the user data when the types of the user data require changes. According to the technical scheme, changes of the data structure can be well adapted under the condition that the software structure is not changed.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data storage, query, and loading method and device. Background technique [0002] Big data is a massive, high-growth and diversified information asset that requires a new processing model to have stronger decision-making power, insight and discovery, and traffic optimization capabilities. To some extent, big data belongs to the cutting-edge technology of data analysis. That is, the ability to quickly obtain valuable information from various types of data is the processing technology of big data. The common characteristics of big data are 4V: Volume, Velocity, Variety, and Veracity (large data volume, fast input and processing speed, data diversity, and authenticity), which put forward higher requirements for storage systems. There are certain disadvantages in data, such as: difficult to search content, high cost of storage system, complex management, etc. [0...
