These migrations are all saved and time-stamped, to make it possible to roll back to previous versions of the data structure.
这些迁移操作都会保存,并加上时间戳,让我们可以回滚到数据库结构的上一个版本。
Now that all necessary schema changes were implemented through migrations, we can upload the XML data into the XML_CONTENTS table.

By allowing changes to data, migrations make it much easier to synchronize changes in data and schema that often come together.
通过允许改变数据,迁移大大简化了相关数据和模式的变化的同步过程。
In addition to structural changes to the database, migrations can include SQL commands for manipulating data.
除了能够对数据库结构做出变更之外,迁移操作中还可以包括用于操作数据的SQL命令。

To continue to take advantage of the flexibility of Ruby on Rails migrations, without giving up the power that comes with XML, let's create a separate table to store XML data.
