Database-Based Examination Software For Chemistry Material

In recent years,the society has already entered the digital information age with computer development. However in some chemistry examination departments, primary methods are used, such as manual memory for mass chemistry data,manual searching chemistry dictionary,manual analysis of testing result, etc. In fact, it is very difficult for manual memory and searching. Sometimes, needed material can't be searched. At the same time, analyzing period of examination result to chemistry material is very long and maybe different results are gotten. All above operations bring much inconvenience for working.The project of examination software for chemistry material is emerging as the times require. It can solve above-mentioned difficulties with computer and chemical technology. Based on database, the paper realizes the process and approach of digital chemical material and experiment data. Also it detailedly describes modeling and improving process of assistant analysis algorithm of unknown material.Firstly, the paper introduces development background of the software and analyzes the requirement of chemical material examination approach. Furthermore, it shows system structure and management model of the software. Secondly, the paper completes detailed designing of framework and database for the system in the designing phase. Also, it has detailedly shown key technologies of the software including model and algorithm of assistant analysis for unknown material, flow designing with adequately using valid standard experiment data.Finally, the paper shows all functions of the examination software for chemistry material and gives testing result and evaluation. At the end, it summarizes all works and puts forward future works.
