Methods of Extracting Information Based on Database Technology

Abstract

According to the ternary number data mining algorithm, this paper combines SQL program operation and Oracle 10 g database system together. And then, numerical modeling and meshing technique are adopted to abstract data parameter from the database system. In addition,a mathematical model is established to abstract information from the ternary number database and the information literacy algorithm is also designed. In order to verify the reliability of the mathematical model and algorithm, a database abstracting numerical simulation experiment is designed for the velocity and temperature parameter. Through the experiment, it is discovered that there does not exist residual shock in the ternary number method when the data is being abstracted, which has a relatively stable convergence. At the same time, this paper gains the speed data distribution vector diagram. Eventually, the reliability of the algorithm designed in this paper is verified by comparing temperature data and the experimental data.
