Front-end CASE的意思|示意

In case the system has a User front-end, it is also critical to design the UI rigorously.

在系统拥有用户前端的情况下，严谨地设计UI也是非常关键的。

The standard for compiler design is to break it in two modules: the front end that reads and decodes the input file, and the back end that produces the code or, in this case, the table class.

编译器的设计标准是将其分成两个模块：前端和后端，前端读取输入文件并对该文件进行解码，后端生成代码，或者在这种情况下生成 table 类。
