Embodiment Construction

[0034] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0035] In an IT system, a data table may contain tens of thousands of records, and it is obviously unrealistic to manually process or evaluate it. Therefore, the present invention proposes a stratified sampling method as follows to analyze the data table records are processed.

[0036] The data stratified sampling method for the IT system application evaluation and expansion platform includes a stratification step and a sampling step, and the stratification step includes:

[0037] 1) Read the data table from the database;

[0038] 2) Based on the field X, the records are stratified or classified by comparison:

[0039] Let the attribute values ​​of field X be: t 1 ...

Abstract

The invention discloses a data stratified sampling method for an application appraisal expansion platform of an information technology (IT) system. The method comprises a stratification step and a sampling step. The method can be used for quickly and effectively stratifying the records in the conventional data table so as to bring convenience to further sampling, the stratification and sampling algorithms reflect that the functions of the records of each category in the sampling records are equivalent to those in the original data table, and the coverage requirement for evaluating various records is met.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data layered sampling method for an IT system application evaluation expansion platform. Background technique [0002] In order to implement the "Eleventh Five-Year Information Development Plan of the State Grid Corporation", implement the SG186 information project of the State Grid Corporation of China, and realize the goal of refined production management, the State Grid Corporation of China decided to organize and develop the production management system (hereinafter referred to as IT system) in 2006 ). The project is developed and implemented by State Grid Electric Power Research Institute. Under the unified arrangement and deployment of the municipal company, Qinan Power Supply Bureau started the promotion and construction of the IT system in May 2009. After the online operation, the IT system is stable and fully functional. works well. [0003] On the basis of the compre...
