Five minutes to give you a clear description of UML

1. Preface

The Design of functional modules is required for projects recently. The customer shall refer to the UML diagram for design materials.

However, after so many years of dealing with the Japanese, I have forgotten what a UML diagram is and I have no choice but to check the materials from the beginning.

So I made such a piece of information and told you how to learn UML, so that you can learn UML in five minutes.

2. First minute-model technology as the Object's representation

Before entering the description of UML technology, let's first talk about Object pointing technology. Object pointing is an advanced technology in software development. As the [Object] name implies, all considerations of this technology start from Object.

Object can improve the development efficiency and speed of large-scale software projects.

The so-called Object pointing means to break down complicated problems in detail and express them in charts. For example

As shown in, a good model can correctly and reasonably express complicated meanings. After the complex path information is simplified, it becomes a clear and visible model diagram.

However, there are various ways to draw model diagrams. How can we accurately and uniformly draw them? See the following section:

3. The next minute-UML technology used as a unified Expression Model

As shown above, it is a good choice and practice to express complex logic and needs in graphs.

However, everyone has different ideas, and the pictures they draw are different. How can we make everyone understand each other's ideas.

At this time, UML was launched. UML was launched by OMG in 1997 and is a globally Unified Model graphics technology.

4. The third minute-UML technology can improve the analysis and design accuracy

When we do not have UML technology, we all know that we are talking about it.

When analyzing requirements, the customer will talk about the requirements at will.

When designing the system, the architect casually talked about the design.

During program development, developers can write programs at will.

Everything is disordered and chaotic, but with UML, this problem will not occur again.

All communication and documents can be delivered in a good way that everyone can understand. This is UML.

5. Fourth Minute-UML content

We can use the UML technology as follows.

In addition, many automatic development tools can automatically generate code according to the form.

6. fifth minute-UML is a required knowledge

For modern software development and management, UML is a required knowledge. Whether it is outsourcing or internal package, UML is an indispensable technology.
