向计算机发出指令的方法有很多种：电气工程师可能会编写 MATLAB 程序；数据库管理员可能会编写 SQL 脚本；硬件工程师可能会用 Verilog 编写；会计师可能会编写带有嵌入公式的电子表格。除了每个示例中使用的语言不同之外，形式和习语也存在重要差异。每个人都使用针对手头工作定制的语言，并且每个人都以程序员熟悉且高效的形式构建计算请求（尽管会计师可能不认为自己是程序员）。简而言之，这些示例中的每一个都使用 DSL（特定于域的语言）。
There are many ways to give instructions to a computer: an electrical engineer might write a MATLAB program; a database administrator might write an SQL script; a hardware engineer might write in Verilog; and an accountant might write a spreadsheet with embedded formulas. Aside from the difference in language used in each of these examples, there is an important difference in form and idiom. Each uses a language customized to the job at hand, and each builds computational requests in a form both familiar and productive for programmers (although accountants may not think of themselves as programmers). In short, each of these examples uses a DSL (domain-specific language).
