是的。代码就是代码。我的经验法则是，我需要能够从头构建和部署应用程序，而不需要查看开发或生产机器。

仅供参考，几天前Dana也提出了这个问题…源代码控制中的存储过程/DB模式

“简短版本:将您的生产数据库转储到git存储库中，以实现即时备份解决方案。”

我非常喜欢Rails ActiveRecord迁移。它将DML抽象为ruby脚本，然后可以在源存储库中轻松地进行版本化。

然而，通过一些工作，您可以做到同样的事情。任何DDL更改(ALTER TABLE等)都可以存储在文本文件中。为文件名保留编号系统(或日期戳)，并按顺序应用它们。

Rails在DB中还有一个'version'表，用于跟踪上一次应用的迁移。你可以很容易地做到这一点。

The most successful scheme I've ever used on a project has combined backups and differential SQL files. Basically we would take a backup of our db after every release and do an SQL dump so that we could create a blank schema from scratch if we needed to as well. Then anytime you needed to make a change to the DB you would add an alter scrip to the sql directory under version control. We would always prefix a sequence number or date to the file name so the first change would be something like 01_add_created_on_column.sql, and the next script would be 02_added_customers_index. Our CI machine would check for these and run them sequentially on a fresh copy of the db that had been restored from the backup.

我们还准备了一些脚本，开发人员可以用一个命令将本地db重新初始化到当前版本。
