当前，系统设计领域的趋势是为每个应用程序或应用程序实例提供单独的系统，比如数据库、Web应用程序或财务包。
The current trend in system design is to provide a separate system for each application or instance of an application, such as a database, web application, or financial package.
比如数据库连接池就是单例设计模式的一个例子：我们一般不想让应用程序具有连接池类的多个资源密集型实例。
An example use case for a singleton would be a database connection pool: you don't want your application to have multiple resource-intensive instances of a connection pool class.
尽管理想情况是保持几乎所有数据(比如数据库和JNDI名称)不变，但也有其他一些值应该从一个环境更改到另一个环境。
While it's desirable to keep almost all of the data the same (such as the database and JNDI names), there are other values that should change from one environment to another.
设置代码通常由一些行构成，这些行是对数据库的描述，比如数据库驱动程序、用户名和密码，以及到哪里去找到它。
The setup code is usually a few lines that describe the database such as the database driver, username and password, and where to find it.
