     92 
     93 上面的操作产生的数据都通过pickle序列化保存到文件里
     94 
     95 pickle 可以直接存储任何类型对象
     96 
     97 需求分析 :
     98 
     99 明确要做的程序 具备哪些功能,并分析 每个功能是否可以用代码实现, 产生需求文档
    100 
    101 技术选型:
    102 
    103   1.要使用的技术是否已经成熟  (使用的人多,有完整官文档,还有相对活跃的社区)
    104 
    105 需要考虑开发团队是否能够hold住该技术
    106 
    107 
    108 
    109 面向对象 还是 面向过程
    110 
    111 如果项目体积较大,后续可能需要修改需求或是增加需求,优先考虑 面向对象
    112 
    113 
    114 
    115 1.分析需求 确定需要哪些对象和类 ,分别有哪些特征和行为
    116 
    117 三层:
    118 
    119 用户层V  接口层C  数据访问层M
    120 
    121 用户层 :与用户交互  输出数据  或者接收输入
    122 
    123 接口层:  1.判断 验证 组装 数据  交给给数据访问层 来存储    2.从数据访问层拿到数据 组装成用户可以看懂的格式 交给用户层
    124 
    125 数据访问:  提供数据的读取和存储
    126 
    127 
    128 
    129 model  模型 就是一个对象 专门用于描述数据  相当于数据容器
    130 
    131   需要的文件应该放在那一层
    132 
    133 与用户直接打交道的  例如请输入功能序号  放到用户层
    134 
    135 user_view
    136 
    137 teacher_view
    138 
    139 admin_view
    140 
    141 一堆类 例如学生 课程   等 放在数据访问层
    142 
    143 接口层:
    144 
    145 user_interface
    146 
    147 teacher_interface
    148 
    149 admin_interface
    150 
    151 数据访问层:
    152 
    153 DBHandler
    154 
    155 标准文件目录:
    156 bin
    157 
    158 start.py
    159 
    160 conf
    161 
    162 settings.py
    163 
    164 lib

    170 user_view
    171 
    172 teacher_view
    173 
    174 admin_view
    175 
    176 db
    177 
    178 DBHandler
    179 
    180 models
    181 
    182 interface
    183 
    184 user_interface
    185 
    186 teacher_interface
    187 
    188 admin_interface
    189 
    190 logs
    191 
    192 一堆日志文件
    193 
    194 
    195 
    196 从用户层开始写  功能选择
    197 
    198 用户的登录 注册
    199 
    200 先后顺序 不是必须的
