Embodiment 1

[0066] At present, in big data platforms based on relational databases, a large amount of data with different structures and different storage methods is often accumulated, including complex multi-source heterogeneous data such as documents and tables. Due to multi-table associated queries and complex data analysis types, As a result, when the number of users and visits is large, the query efficiency is extremely low. As a result, the functional and performance limitations of traditional relational databases have become increasingly apparent.

[0067] In order to solve the foregoing problems, this embodiment provides a data traceability method, which is mainly oriented to non-relational databases, such as figure 1 As shown, the data traceability method includes the following steps:

[0068] Step 10: Add unique identification information to each piece of source data to establish an original data set, wherein the original data set contains at least one piece of source data.

...

Embodiment 2

[0132] see Figure 19 , Figure 19 It is a schematic structural diagram of a data traceability device provided by an embodiment of the present invention. The data traceability device in this embodiment includes one or more processors 31 and memory 32 . in, Figure 19 A processor 31 is taken as an example.

[0133] Processor 31 and memory 32 can be connected by bus or other means, Figure 19 Take connection via bus as an example.

[0134] Memory 32, as a non-volatile computer-readable storage medium based on data traceability, can be used to store non-volatile software programs, non-volatile computer-executable programs and modules, such as the data traceability method in Embodiment 1 and corresponding program instructions. The processor 31 executes various functional applications and data processing of the data traceability method by running the non-volatile software programs, instructions and modules stored in the memory 32, and realizes the data traceability method of ...

Abstract

The invention discloses a data tracing method and a corresponding data tracing device, and the method comprises the steps: adding unique identification information to each piece of source data, and building an original data set; Performing a target data operation on the original data set to obtain a target result set matched with the target data operation, each result record comprising identification information of source data matched with the result record; And integrating the tuple numbers of the result records, the identification information contained in the result records and the target data operation to obtain traceability information corresponding to each result record so as to carry out data traceability according to the traceability information. According to the data tracing method, in the data tracing process, according to the data operation in the tracing information, the identification information of the source data, the source of the result record and the evolution process,the reliability and reliability of analysis of the source of the result record are improved, and the data tracing efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of databases, and more specifically relates to a data traceability method and a corresponding data traceability device. Background technique [0002] Data traceability refers to the process of tracking the origin and derivation of data. In the era of big data, due to factors such as the stages and technicalities of data collection and the characteristics of different types of data, a large amount of data from different sources and of different quality has been accumulated in the process of data collection. Taking the government big data sharing platform as an example, the platform collects a large amount of data generated during the business operation of various subordinate application systems and websites, and conducts unified and centralized analysis of the above data, so as to provide various departments with auxiliary decision-making, statistical analysis and business management, etc. Full support. Sup...
