PowerDesigner概念模型详解

环境PowerDesigner12.5WindowsXP中文版一、概念模型的重要性PowerDeigner是最强大、最优秀的数据建模工具，是Sybase公司最伟大的产品。目前最新版本是12.5，从9一直用到现在，对PD的认识也是在逐步加深。常常在工作中，看到大家用PD，都是用来建几个表，实际上是做PDM，上来就干这个，实际上，这么用PD，是对强悍的PD一种侮辱。PD仅仅是这么玩的吗？数据库设计的步骤是什么，难道上来稍稍想一下就搞个pdm出来？下面简单回顾下

hessian 报 'j' is unknow code故障分析

今天突然发生了一件怪事，在内测环境下所有的客户端通过hessian请求服务端时，部分的请求直接返回'j'isunknowcode，服务端并不报错。发生这个问题，真把我给急坏了，内测环境是我们上线生产的最后一道关，如果这个故障不解决，所有的应用都要停止上线，以免给生产系统造成影响。一方面更新邮件不停的在累积，另一方面，出于对生产系统负责的态度，不敢对生产环境进行更新。某大神一直认为是项目中的包的版本的问题，不断的让我换依赖包的版本，当时我也没有太好的排查方案

Python

python读取大文件越来越慢的原因与解决

背景：今天同事写代码，用python读取一个四五百兆的文件，然后做一串逻辑上很直观的处理。结果处理了一天还没有出来结果。问题出在哪里呢？解决：1.同事打印了在不同时间点的时间，在需要的地方插入如下代码:printtime.strftime('%Y-%m-%d%H:%M:%S',time.localtime(time.time()))发现一个规律，执行速度到后面时间越来越长，也就是处理速度越来越慢。2.为什么会越来越慢呢？1）可能原因1，GC的问题，有篇文章
