UML，HLD和LLD示例 [英] UML, HLD and LLD examples

问题描述

i需要对UML文档进行一些澄清



1.什么是UML

2. UML与HLD和LLD的区别。

3. UML，HLD和LLD的示例图。

解决方案

< blockquote> UML（统一建模语言）

是一种使用标准对象集描绘代码的方法/其他开发人员可以快速理解的符号。类似UML或UML的设计通常可以从VisualStudio中的现有代码或通过其他程序生成。



HLD - 高级设计doc 示例

本文档将讨论最高级别的设计。哪些服务/程序在哪些机器/数据中心上运行，这些数据中心如何交互，涉及哪些其他系统（sql机器，防火墙，网站等）。这也可以被认为是一个建筑设计文档。



LLD - 低级设计doc 示例

这将是对您的设计的高度技术性的看法。您将在此处包含您的UML图表，如果可能，请使用伪代码进行拆分和解释。它还将包括消息模式，XSD以及您可以收集的任何其他技术信息。



HLD和LLD通常都有一个非常标准的布局，可以帮助您将信息整合在一起。

Hi,

i need some clarification on UML documentation

1. what is UML
2. how UML different from HLD and LLD.
3. sample diagram for UML,HLD and LLD.

解决方案

UML (unified modeling language)
is a way to depict code using a standard set of objects/notations that can be quickly understood by other developers. UML or UML-like designs can often be generated from existing code in VisualStudio or through other programs.

HLD - High level design doc example
This doc will talk about the design at the highest level. What services/programs are running on what machines/data centers, how these data centers interact, what other systems are involved (sql machines, firewalls, web sites, etc). This can be thought of as an architectural design doc as well.

LLD - Low level design doc example
This is going to be highly technical look at your design. You will include your UML diagrams here, split up and explained with pseudocode if possible. It will also include message schemas, XSDs, and any other technical information that you can gather.

Both the HLD and LLD generally have a pretty standard layout to help get your information together.

这篇关于UML，HLD和LLD示例的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
