凌云论坛(LyBBS)的架构是基于Jsp/JavaBean的模式，这种模式非常稳定，而且，速度比较优越，是被全球企业证明的可以高效稳定的进行企业运算开发的平台。这种平台最大的优势在于可以跨系统，真正的“一次编写、 到处运行”的特点，在这种平台上开发的产品，可以轻松移植到其他的平台，例如：Unix、Linux、Windows系统，这样，在企业更换平台的时候可以最大的节约成本，提高运算质量。-Lingyun Forum (LyBBS) framework is based on Jsp/JavaBean model, very stable, but relatively superior speed, was global enterprises could prove highly efficient and stable development of enterprise computing platform. This platform is the greatest advantage of cross-system can be real "time to prepare, run everywhere" to the characteristics of this platform in the development of products that can be easily ported to other platforms, such as : Unix, Linux and Windows systems, so that the enterprise platform to replace the time available with the greatest cost savings, improve the quality of operations.

Lex是美国Bell实验室用C语言研制的一个词法分析程序自生成工具。它的基本原理就是使用正则表达式扫描匹配文本，并为每一个匹配模式定义一些操作，当用C语言作宿主语言时，这些操作都由C语言实现。一种匹配的正则表达式可能会包含相关的动作。这一动作可能还包括返回一个标记。当 Lex 接收到文件或文本形式的输入时，它试图将文本与正则表达式进行匹配。它一次读入一个输入字符，直到找到一个匹配的模式。如果能够找到一个匹配的模式，Lex 就执行相关的动作（可能包括返回一个标记）。-Lex Bell Laboratories of the United States with C language developed by a lexical analysis tool generated from the process. Its fundamental principle is to use a regular expression matching text scanning, and for every definition of a matching model for operation, when the C language of the host language, these operators by C language. A match of which is likely to contain expressions related to the moves. This action may also include the return of a marker. When Lex reception of the document or text input, it is trying to text and is a regular expression matching. It read an input into the characters, until they found a matching pattern. If they can find a matching model, Lex on the implementation of the action (which may include a return of markings).
