许多人不知道的是，提供这项功能的 CPAN 模块实际上只是内部应用程序接口（API）的包装器。

What many don't realize is that the CPAN module that provides this functionality is actually just a wrapper around an internal application program interface (API).

SCA应用程序驻留在类似于WebSphere Integration developer容器的抽象容器中，称为SCA模块，一般包含业务对象(BO)、接口、导出和导入。

SCA Applications are housed in a WebSphere Integration Developer container-like abstraction called an SCA module, which typically contains business objects (BOs), interfaces, exports, and imports.

组件化可通过为无法访问的内部功能(如在交互产品订购应用程序中的折扣计算)创建接口来使得应用程序模块化。

Componentization makes an application modular by creating interfaces to formerly inaccessible internal functions (such as discount computations in an interactive product-ordering application).
