申请 PyCon Asia Pacific 2010 准备的主题——基于三元语义的关系数据库建模工具Socrates
摘要：基于三元语义的关系数据库动态建模工具SocratesSocrates, Relational Database Dynamic Models Make Tools摘要 SummarySocrates是一个基于关系型数据库和ORM的通用数据库工具。它通过三元语义表达了对动态数据结构的存储和管理功能。使得开发人员可以在关系数据库中管理结构可变的数据。三元语义可以方便的表达单一信息之间的关系，因此它很适合用来表达有向图，甚至有向有环的网状模型，或路径长度很长的关系。预计时长：25分钟难度 Level ：面向中级听众类别 Categories：数据库 databases详细内容 Description 阅读全文

sqlalchemy、storm和web2py dal的比较报告
摘要：工作项目报告，所以抹掉项目名先，以“X”代之。分割线内内容仅代表个人意见，与所供职企业及参与社区无关。===================================X 从很早的时候就出现各种数据库访问错误。包括链接数占用过多，死锁，僵尸事务等。本周我集中梳理了一遍代码。我认为，虽然数据库设计方面有诸多不合理之处，但是这些不合理主要影响业务错误，造成 X 性能和使用上的问题是因为使用的ORM框架 storm 有严重的缺陷。首先，storm 对数据库架构的同步有非常奇怪的设定。它不自动同步表结构，却插手外键关联关系。强制要求外键必须都是级联更新、级联删除、set null。且不说其设定中有 阅读全文
