我觉得我的商店有一个漏洞,因为我们没有一个可靠的过程来控制数据库模式更改的版本。我们做了很多备份,所以我们或多或少地得到了保护,但以这种方式依赖于最后一道防线是一种糟糕的做法。
令人惊讶的是,这似乎是一个共同的主线。与我交谈过的许多商店都忽略了这个问题,因为他们的数据库不会经常更改,他们基本上只是尽量做到一丝不苟。
不过,我知道这个故事是怎么发展的。这只是时间问题,迟早会出问题,会有东西丢失。
在这方面有什么最佳实践吗?你有哪些行之有效的策略?

Sadly, I've seen more than one team developing PL/SQL programs (stored procedures in Oracle) - sometimes ten thousands LOC - just by editing the code in TOAD (a database tool), without even saving the source to files (except for deployment). Even if the database is backuped regulary (wouldn't take that for granted, though), the only way to retrieve an old version of a stored procedure is to restore the whole database, which is many GB large. And of course sometimes concurrent changes in one file lead to loss of work, when more than one developer works on the same project.

是的……我们的数据库是在ERwin中设计的,每个版本的ddl是自动生成的。ERwin文件保存在我们的源代码控制系统中(实际上,我们的工程文档也是如此)。
对于oracle,我使用自己编写的java程序oracle-ddl2svn自动跟踪oracle DDL方案在SVN中的变化
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。
Here is a sample poor man's solution for a trigger implementing tracking of changes on db objects ( via DDL stateements ) on a sql server 2005 / 2008 database. I contains also a simple sample of how-to enforce the usage of required someValue xml tag in the source code for each sql command ran on the database + the tracking of the current db version and type ( dev , test , qa , fb , prod) One could extend it with additional required attributes such as , etc. The code is rather long - it creates the empty database + the needed tracking table structure + required db functions and the populating trigger all running under a [ga] schema.

在我们的业务中,我们使用数据库更改脚本。运行脚本时,它的名称存储在数据库中,并且不会再次运行,除非删除该行。脚本是基于日期、时间和代码分支命名的,因此可以控制执行。
在脚本在实际环境中运行之前,已经完成了大量的测试,所以一般来说,“oopsies”只发生在开发数据库上。
