EA introduction notes
2022-07-05 08:35:00 【Learn open source together】
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
