持久化一般放在模块内部，还是放在主应用上？ #16

大部分情况下我们需要的树形数据都很简单，所以我想在你的模块上提供一个默认实现（假如叫DefaultTree），关于持久化有两种想法

1、在模块内部实现持久化
在DefaultTree.Core中定义DefaultTreeEntity，实现IGeneralTree<TTree, TPrimaryKey>
在DefaultTree.EF中定义DBCotnext，其中定义DbSet
甚至继续提供应用服务TreeAppService、和一个通用的UI

2、模块中不处理持久化
在DefaultTree.Core中定义DefaultTreeEntity，实现IGeneralTree<TTree, TPrimaryKey>
在**主程序(也就是模块的使用方)**的DbContext去定义DbSet

前者这种方式如果我的系统有很多模块都涉及到持久化，那么我可能需要很多DbContext
后者这种方式感觉封装性不够强
请教下你有好的建议吗？ 还是我哪想错了?
