Problems solved by technology

[0004] In the process of obtaining the data in the CSV file mentioned above, the inventor found that for different businesses, a relatively fixed business logic for data acquisition and format conversion needs to be constructed, and the process of data acquisition cannot be reused, so it will be formed in the system. Many code fragments increase the difficulty of system maintenance

Abstract

The invention discloses a data acquisition method and device, relates to the technical field of internet, and aims at solving the problem that the process of acquiring data in CSV files is not reusable in the prior art. The method comprises the following steps of: receiving metadata information corresponding to a business requirement, wherein the metadata information comprises an attribute name, a row identifier and a format type corresponding to different pieces of attribute information, and the row identifier is an identifier of a row in a Comma-separated values CSV file; establishing a mapping table according to the metadata information, wherein the mapping table records a corresponding relationship among the attribute name, the row identifier and the format type; extracting data corresponding to the row identifier from the CSV file according to the mapping table; converting the extracted data into a format type corresponding to the row identifier according to the mapping table; and binding the format-converted data with the attribute name corresponding to the row identifier. The data acquisition method and device are suitable for being applied to the process of extracting the data in the CSV file.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a data acquisition method and device. Background technique [0002] When users need to exchange information, it may be necessary to import a database program that stores data in a proprietary format into a spreadsheet with an entirely different database format. Usually, the program that stores the database in a private format is first exported to the "Comma-Separated Values ​​(CSV)" format. The CSV format is a common and relatively simple method that is widely used to transfer table data between programs. file format. Then import the file in CSV format into a spreadsheet with a completely different database format. [0003] When importing a CSV format file into a new spreadsheet, it is necessary to obtain data from the CSV file. The existing process of obtaining data in the CSV file is: read each row of data in the CSV file; create according to the specific busines...
