+note, notebook都可设为blog

+
+??? 不用新建, 直接使用notes表, 添加IsBlog字段. 新建表 blogs {NoteId, UserId, CreatedTime, IsTop(置顶)}, NoteId, UserId 为unique!!
+
+// 设置一个note为blog
+添加到blogs中
+
+// 设置/取消notebook为blog
+创建一个note时, 如果其notebookId已设为blog, 那么添加该note到blog中.
+设置一个notebook为blog时, 将其下所有的note添加到blogs里 -> 更新其IsBlog为true
+取消一个notebook不为blog时, 删除其下的所有note -> 更新其IsBlog为false
