4 | 数据库在某些特定需求下是很重要的，像持久化数据，一些不需要实时或者长时间不变的数据，
5 | 可以放在数据库中做缓存，这样就算用户网络不好或者断网的情况下，依然是可以查看一些以前的数据。像新闻或者咨询类。
6 | 这样做是不可避免的。提高用户的体验。谷歌为我们开发者提供了最基础的数据库操作类，
7 | 同时也提供了SqliteDatabase直接创建修改数据库和表。但是只是这样不能满足我们平时的敏捷开发。
8 | 作为一个应用层程序员，很多时候只是想去关心存储和读取数据，数据处理等问题的解决。
9 | 而不是花时间和精力在如何去存，如何去取数据库数据。这就是架构出现的前提。
10 | 将一些面向过程的算法或者业务逻辑封装，可再次调用。易扩展、高灵敏。让程序猿专心的去整理项目需求和逻辑。
11 | 解放大脑，提高工作效率。
12 |
13 | 现在数据库有很多三方框架，比如GreenDao,Afinal、xUtils、ThinkAndroid、volley等等。但是这些三方导入后，文件数太大了。而且很多都集成了网络加载框架，图片加载框架。这样就有了一定的耦合性。比如我只喜欢xUtils的数据库框架，不喜欢它的网络加载，想用Volley的网络加载框架。咋办呢？两个都导入？是的，可以这样，但是项目的文件数就太大了。编译时压力大。而且一些公司想让程序猿写自己的框架，不使用别人发布的框架，这样代码是可以高扩展的。出现什么问题也是可以及时修改。如果导入的三方库在项目成熟阶段出现问题。那是不是要推翻这个库，重新去导入一个，重新在写一遍逻辑，而且又有谁能保证，再次导入的库不会出错呢？
14 |
15 | 我把大致的封装思路，以图片的形式展示出来。
16 |
17 | 
18 |
19 | 对应的UML逻辑图
20 |
21 | 
22 |
23 | 使用起来也非常方便，这里的映射逻辑和GreenDao的底层源码使用的是一个原理。采用表和类属性映射，并对其进行了缓存。只有在切换表的链接时，会重新建立链接。
24 |
25 | 优点：
26 |
27 | 1、支持sql语句自拼接。数据库直接执行sql语句。
28 |
29 | 2、支持传入类对象进行增删改查，比如User，在insert的时候，插入User的实例，属性都封装在user中。通过反射获取它的属性值，存入数据库。
30 |
31 | 3、高扩展，每个新建的存储类型。直接继承DefaultBaseDao即可。可以在这里做一些该类独有的操作。
32 |
33 | 4、支持多数据库切换，多数据库操作。同时支持数据库分库管理，多数据库多版本多用户同时升级，采取XML脚本升级。这里的脚本语句没有封装。
34 |
35 | 5、支持boolean、byte、short、int、long、float、double数据类型的存储和读取。
36 |
37 |
38 |
39 | 使用注意事项：
40 |
41 | 1、创建存储数据类时，需要使用注解去标注类名（表名@DbTable）、类属性（表字段@DbField）。若是有主键（@DbPrimaryField）也需要标注。
42 |
43 | 2、需要创建一个相应的Dao层类和数据库的链接。
44 |
45 |
46 | 使用时导入gandle： compile 'com.singleshu8:LemonDao:1.0.4'
47 |
48 | 创建一个Dao层，这里可以操作数据库，像多数据升级时，这里可以做一些特定处理。对外扩展

397 | 有关于数据库分库和多版本多用户脚本升级，这个在小项目用的很少。小项目一般是几张表就搞定了。查询是加个userId，但是当
398 | 数据量过大时，这样做会很难受。数据库升级在表少的时候，可以直接拼接字符串。但是当表多了之后，这样做无疑是不正确的。
399 | 若是对数据库分库和多版本多用户升级感兴趣的朋友。可以联系我，794918578@qq.com；
