Default Database Directory

When a database is created, information about the database, including default information, is stored in a directory hierarchy.

创建一个数据库时，关于数据库的信息，包括默认信息，存储在一个目录层次结构中。

You don't need to create a directory tree or message database for the default locale; the strings for that locale are already embedded in the code.

无需为默认语言环境创建目录树或消息数据库；用于该语言环境的字符串已经被嵌入到代码中。

In particular, ensure the logs aren't left in their default location under the instance directory, since by default the database itself is also located here.

特别地，确保没有将日志保存在实例目录的默认位置，因为默认情况下数据库本身也位于这里。
