Java实现长途话务流量流向辅助分析系统及其性能优化

Implement long-distance telephone flux and flow assistantanalytical system in java and optimize it's performance

Java实现数据入库和计算量大、逻辑复杂的业务报表,一直很少有这方面的成功例子。以实现长途话务流量流 向辅助分析系统为例,阐述了如何利用免费开源的软件包,纯Java实现Excel报表、图表以及完善日志系统的典型实际例 证。就如何提高Java程序性能,提出了开发中性能优化应该注意的方面。

Aiming at implementing data into database and vast computing and complicated logic operation report forms in java, there are less successful examples. Long-distance telephone flux & flow aided analytical system is a typical sample, which is expatiated on implementing Excel report forms, chart and self-contained log with using free open source software package. Furthermore, performance optimize in the development is indicated for improving java program's performance.
