In the painting ER diagram when looking for a more useful and professional point of the tool, looking for a half-day finally chose the seemingly less professional EA to draw ER diagram
Briefly explain how the EA is implemented to draw ER graphs
First, the Operation procedure
1. After creating a new project in the EA, select the model below
2. Then double-click the design Model on the right to create a new chart
Select Data Modeling
3. Then you can draw the ER diagram, the effect is as follows
The drawing looks really nice.
Second, expand
After using an EA to draw an ER diagram, you can also add attributes to entities and contacts, and then export the entire ER diagram so that the database design instructions are written
Book when you do not have to write one by one, is also a very good function
Room entity and contact is not too much, with EA is not too suitable, so there is no specific operation, we are interested to try
Iii. Summary
Learning all the time, everywhere, take the EA to say, just at the beginning I really do not know it also has the function of drawing ER diagram, now found
The EA functions well, and there are a lot of features that we haven't found.
Learning is definitely not just the part you see.
