The Simulation Study on the Algorithm Optimization of the Backup of Table Space Based on the Petri Net

针对信息系统业务处理过程中,传统的表空间备份算法设计的数据库表存在占用空间大,且冗余信息多的问题,本文基于Petri网理论进行了重新建模和分析,并在此基础上提出了一种新的算法和优化解决方案,最后使用MATLAB下的Petri网工具箱对算法进行了建模仿真分析和验证。实验证明,该算法及方案有效地解决了传统表空间备份算法浪费资源的问题。同时证明了该算法在实际应用中减小信息导入过程中的二次误操作对表空间数据的损坏。

For information systems business processing process in the, traditional of table space backup algorithm design of database table exists occupies space large, and redundant information more of problem, this article based on Petri network theory for has again buih die and analysis, and this based Shang made has a new of algorithm and optimization solution programme, last using MATLAB Xia of Petri network Toolbox on algoridlm for has built die simulation analysis and validation. Experiments show that the algorithm and programmes effectively solved the problem of traditional table spaee backup algorithm a waste of resources. Also proved that the algorithm reduces information in the practical application of seeondary, mistake on the table during the import process of spatial data is damaged.
