进入microsoft visio 进行UML等模型工具进行各种操作,有啥感受?

Posted 2023-03-21

参考技术A 使用后感受，两者区别：
UML不是用来画图的，它是一种建模工具，在给软件建模的时候需要用UML的工具来画一些图。
而VISIO纯粹是个画图工具，不是建模工具。现在UML工具除了英文的外，也有中文的，比如国内一个名叫楚凡科技的公司开发的UML建模工具Trufun Plato就是个中文界面，很适合你这样的初学着。

系统设计与数据库系统 作业五 UML System Design using Microsoft Visio

Design a DFD for a Cash Dispenser (ATM Machine) with the following functions:

1. “The Cash Dispenser system uses four processes:
   a. Receive-Request
   b. Check-Password,
   c. Withdraw, and
   d. Show-Balance.
2. Process Receive-Request takes a request for either withdrawing or showing the balance, and sends this request to either process Withdraw or Show-Balance. At the same time, it also sends an instruction to Check-Password to check whether the input card and password are correct.
3. Check-Password then sends a confirmation to both Show-Balance and Withdraw.
4. Withdraw: requests an amount from the customer, and outputs the amount of the money if it is within the range of the account balance.
5. To determine whether the requested amount is small enough to be withdrawn, the system needs to keep the file account that allows all the related processes to access.
6. Show-Balance: outputs the present balance

Draw : Use Case Diagram by identifying

1. actors who use the ATM
2. Functionality of every Actor of the ATM software.
3. other components which you think is required for ATM and
4. Functionality of these component of the ATM software.

and the convert it into the following DFD
（1）Context Diagram
（2）Level0 DFD
（3）Level1 DFD

2. Draw Use Case Diagram for a Blog Website
Identify the following requirements
(1) actors who use the Blog software
(2) Functionality of every Actor of the Blog software.
(3) components of Blog software and
(4) Functionality of each component of the Blog software.
