关于数据库模型本身有很多讨论，但是我们也将所需的数据保存在. sql文件中。

例如，为了让你的应用程序更有用，你可能需要在安装时这样做:

INSERT INTO Currency (CurrencyCode, CurrencyName) 
VALUES ('AUD', 'Australian Dollars');

INSERT INTO Currency (CurrencyCode, CurrencyName) 
VALUES ('USD', 'US Dollars');

我们会有一个名为currency的文件。subversion下的SQL。作为构建过程中的一个手动步骤，我们将比较以前的货币。SQL到最新版本，并编写升级脚本。

我们在源代码控制下有创建/修改脚本。至于数据库本身，当您有数百个表并且每分钟处理大量数据时，对所有数据库进行版本化将是CPU和HDD的杀手。这就是为什么在我看来，备份仍然是控制数据的最佳方式。

这对我来说也一直是一个很大的烦恼——似乎对开发数据库进行快速更改，保存它(忘记保存更改脚本)太容易了，然后你就卡在那里了。您可以撤消刚才所做的并重新做它以创建更改脚本，当然，如果您愿意的话，也可以从头开始编写它，尽管这将花费大量的时间来编写脚本。

A tool that I have used in the past that has helped with this some is SQL Delta. It will show you the differences between two databases (SQL server/Oracle I believe) and generate all the change scripts necessary to migrate A->B. Another nice thing it does is show all the differences between database content between the production (or test) DB and your development DB. Since more and more apps store configuration and state that is crucial to their execution in database tables, it can be a real pain to have change scripts that remove, add, and alter the proper rows. SQL Delta shows the rows in the database just like they would look in a Diff tool - changed, added, deleted.

一个很好的工具。以下是链接: http://www.sqldelta.com/

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)。

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。

数据库本身?没有

创建它们的脚本，包括静态数据插入、存储过程等;当然可以。它们是文本文件，它们包含在项目中，像其他东西一样签入和签出。

当然，在理想情况下，您的数据库管理工具可以做到这一点;但你必须遵守纪律。
