EA introduction notes

I'm studying recently EA（Enterprise Architect） Use , Find out EA It's really a powerful design tool , But there are too few learning materials limited to Chinese , Study and record again and again for subsequent reference

This chapter first records the scattered notes recorded during the early use

1. Call in the console window ：Start–>Design

Here's the picture ：

2. Set the connection style and rules

When using to establish the relationship between elements ,Association The default is without arrows , Here's the picture

How to make lines wait for arrows , Do the following ：
1） Set up Association Default with arrow ;2） Remove strict connector syntax restrictions

After setting as above , To re-establish a relationship is to have an arrow , And all Association Lines will have arrows , The effect is as follows

3. stay EA Of Toolbox Introduce elements of other design models ( Take the introduction of package graph as an example )

Generally, you need to select a model when creating a diagram , By default, the tool elements of the selected model , How to load tool elements of other models on this , Set as follows
1） The toolbar , Select the icon above –> choice Change Perspective -->UML–>Structural; Click... After selection Toolbox Of
Then choose... From the pop-up menu Package menu , This time, you can see that the content of the toolbar has become Package The content of

2） Choose Package, The right choice Pin in Toolbox;( Put this element in Toolbox)

3） Click the toolbar again , Select from the menu Default, Enter the original design toolbox , You can see Package Has been added to the current design

4. Change the design element type

For example, will business object Change it to Class type , Just do the following

Keep setting up

Keep setting up

5. How to use EA Implement reverse engineering

Select the corresponding development language , You will be prompted to select the corresponding source directory , After selection, the program will automatically extract the corresponding source file , Generate class diagrams and relationships

6. stay EA Many people cooperate

EA Different versions are available , Support multi person collaboration in team edition and Enterprise Edition , Here we mainly introduce the ways of offline collaboration ; Merge multi person design and multi person design draft through import and Export ;

1） Plan the module and the content outline to be designed in advance

2） Export design content by module or folder

export : Select the folder to export , Then through the shortcut key Ctrl+ALT+E Realization XML Export of

3） Co draft ： Import the design materials of many people to form a complete design draft

Import , Select the folder or module to import , Via shortcut key Ctrl+ALT+I Import

The above example is to import the business model just exported into the module of model overview again , Just selected the import of extreme package , Therefore, you need to enter a version number after the import is successful ( Here, the version number can be defined according to your own situation )

The effect after import is shown on the right side of the above figure , My business model has been imported under the current module

7. EA How to draw the end lifeline

The following legend , You need to draw the following hierarchical

1） Set new lifeline ： Pass on the canvas Pull out the corresponding lifeline , Then draw the call message line in turn , Pay attention to setting properties in the property panel Lifecycle, If it is new, start with the corresponding line

2） Set delete lifeline ：

3） Set execution conditions ：

8. This is the author of the design document , Do the following

9. Export of document template

When we're in EA An export document template that is not easy to configure in , In order to share it with other partners or save it for later use , You can export it and share it , You can export the document template as follows

10. State diagram and state machine

1） Create a state machine diagram , Do the following

On the given canvas, drag and drop the corresponding state entity through the toolbox to draw the state diagram , Here's the picture

summary

The above is the preliminary study EA Some usage records in the process , Later, I will make a further introduction to the drawing of specific different types of maps when I have time
