MantisBT是一个基于Web的错误跟踪系统，于2000年11月首次面向公众提供。随着时间的推移，它已经成熟并获得了很大的普及度，现在它已经成为最受欢迎的开源bug /问题跟踪系统之一。MantisBT采用PHP开发，支持多种数据库后端，包括MySQL，MS SQL和PostgreSQL。 作为一个PHP脚本，MantisBT可以在PHP支持的任何操作系统上运行，并支持其中一个受支持的DBMS。已知MantisBT可以在Windows，Linux，OS / 2，Mac OS X，System i以及各种Unix操作系统上正常运行。

1、什么是框架？ •特征1：是一堆代码的集合； •特征2：一个半成品的应用； •特征3：包含了一些优秀的设计模式； 定义：框架是一堆包含了常量、方法和类等代码的集合，它是一个半成品的应用，只包含了一些项目开发的时候所使用的底层架构，并不包含业务逻辑，框架还包含了一些优秀设计模式，如单例模式、工厂模式、AR（Active Record）模式等。 2、为什么要使用框架？ 在以后实际开发的时候会有一个成型的开发流程： 如果在上述的流程中不使用框架进行开发会遇到哪些问题？ •代码风格不一样，维护困难，可能会造成项目生命周期短； •一处小的修改，会牵扯出很多地方的修改； •在后期满足客户需求方面（功能扩展）存在局限性；
