Problems solved by technology

However, whether it is building a full index or using a full index to find the last version of a certain data, it is quite time-consuming
Another approach in the prior art is to make each table have an attribute to store the time when each piece of data is stored or modified. However, this method needs to scan all the data to find the last version of a certain data , is also extremely time-consuming

Abstract

The invention discloses a data management device and method, and a computer storage medium thereof. The data management device comprises a memory and a processor, wherein the processor is electricallyconnected to the memory, the memory stores a dimension data table, the dimension data table has a plurality of attributes, and a subset of a plurality of attributes is defined as an index attribute,the dimension data table comprises a plurality of members, and each member comprises index data corresponding to the index attribute. The processor creates a last index for each distinct index data ofa plurality of index data, and each of the last indexes points to a last stored location of the corresponding index data in the dimension data table.

Description

technical field [0001] The invention relates to a data management device, method and computer storage medium thereof. Specifically, the present invention relates to a data management device, method and computer storage medium for efficiently managing data with indexes. Background technique [0002] In recent years, due to the rapid development of network communication technology and social media, some new forms of data service requirements have been derived. These new forms of data service requirements have some key characteristics. First, the content of the data is quite diverse, so multiple tables are used to store different items of a piece of data. Second, after saving a piece of data, the user usually needs to modify a certain (or some) item of the data one or more times, and needs to keep each version of the modified item of the data (that is, need to record the footprint of the data). Third, no matter how many times a piece of data has been modified, when it is ne...
