Problems solved by technology

[0003] However, the current data extraction and conversion methods in the industry do not take into account the complex heterogeneous situation, and do not consider the relatively complex situations such as master-slave table splitting, file migration, and file storage format conversion. In these cases, it is impossible to find existing results, and it is necessary to spend resources to do custom development for specific situations; on the other hand, some tools are not converted methods and functions, but the coverage is not comprehensive, and it is difficult to meet the various complex heterogeneous needs of the project at one time Extract conversion

Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] Such as figure 1 , 2 As shown, this implementation selects two sets of heterogeneous data structures for illustration, and the implementation steps are as follows. a) Compare the organizational relationship of tables with heterogeneous data structures before and after, including the data in the tables, the type of information described in the tables, the expression form of the master-slave tables, etc. Find out the similarities and differences in the above aspects, and mark the corresponding relationship between the front and rear table structures according to the number of tables and the form of the master-slave table according to the similarities and differences.

[0043] b) Compare the field correspondences of the heterogeneous data structures before and after, and mark the same corresponding fields in the software.

[0044] c) Comparative ...

Abstract

The invention discloses a data extraction and conversion method covering complex heterogeneous conditions. The method comprises the following steps: firstly, investigating difficulties and problems encountered in a heterogeneous data conversion process, and summarizing the problems to form a heterogeneous data conversion problem library; and proposing a solution for each problem, and gathering thesolutions to form a set of solutions. According to the heterogeneous data conversion method and device, various heterogeneous conditions including different data organization structures, different storage forms, different metadata, attachment migration and the like during heterogeneous data conversion are solved, and the conversion efficiency between the heterogeneous data is improved.

Description

technical field [0001] It means that the present invention belongs to the technical field of data processing, in particular, a data extraction and conversion method covering complex heterogeneous situations. Background technique [0002] Data extraction and conversion is a data processing process that flows from different heterogeneous data sources to unified target data in the process of data flow. Data extraction and conversion is the basis of data application, and it is widely used in big data computing processing and data mining analysis in various industries. There is an increasing demand for data extraction and conversion algorithms with complete functions and excellent performance. The key to data application. [0003] However, the current data extraction and conversion methods in the industry do not take into account the complex heterogeneous situation, and do not consider the relatively complex situations such as master-slave table splitting, file migration, and fi...
