国土资源网上交易系统内核优化设计研究

Core Structural Optimization Design of Land Resources Online Transaction System

国土资源网上交易系统是使用信息化技术,将传统线下国土资源交易嫁接到互联网上进行交易的系统,其对实时性、稳定性和安全性要求极高.目前国内投入运行的网上交易系统在响应速度、稳定性方面大都存在一定缺陷,本文从系统数据库设计、核心引擎结构设计方面讨论其内核的优化.数据库设计方面,对其关系进行横向、纵向切割等方式进行优化,使得资源平均查询时间缩短近一半,且系统响应速度不会随着交易量的累积而明显变慢;核心引擎方面,通过增加资源池、线程池等方法,使得同等运行环境下其内核处理能力至少提升3倍.论文提出的优化设计技术在江西省国土资源网络交易系统升级改造中得到了应用,实际运行效果良好,为其他类似系统的设计及优化改进提供了重要参考.

Land Resources Online Transaction System（ LROTS） transfers the traditional manual transaction to automatic and real time pattern in the environment of internet. It needs the high performance of real time,stability and security to run the LROTS. In this paper the core structural optimization design is realized by optimizing the technologies of database design and core engine structure design. In the aspect of database design,the relationships of crossranges and endwise are optimized,and the average time of the resource query can be cut half.Meantime,the speed of the system respond does not slow down apparently as the amount of transactions accumulate. In the aspects of core engine structure,the processing ability of the core engine is promoted to 3 times through increasing the resource pools and thread pools in the same runtime environment. The proposed optimization is then applied to the land resources online transaction system in Jiangxi Province with good results,which is referential to similar design and optimization.
