For example, Microsoft Visio is a flowchart and ER diagram creation tool. It provides a large number of shapes and templates and can be used to draw flowcharts, organizational charts, maps, networks and graphic designs extensively. ER/Studio is an efficient database design tool that can help users complete the entire process from requirement collection, conceptual design to physical design in the database design process, and supports a variety of relational database systems. DbSchema is a versatile database design tool that supports multiple database platforms and can help users draw complex ER diagrams and relational schema diagrams, and generate SQL statements at the same time.

These software can be downloaded from the official website or other software download sites.

2. Open source ER diagram production tools

Some people don’t like to use paid software, so we can choose some free and open source ER diagram production tools, such as Dia, MySQL Workbench, PowerDesigner, etc. .

Dia is a GNU drawing tool that can be used to draw a variety of technical drawings, including network diagrams, flow charts, circuit diagrams and ER diagrams. MySQL Workbench is a popular MySQL database management tool that can be used to design, model, manage and maintain MySQL databases. PowerDesigner is a powerful data modeling and database design tool that can support a variety of database systems.

These software are all open source, users can download and try to use them from the official website or other software download sites.

3. Use Python to make ER diagrams

In the field of programming, Python is a very popular programming language. We can use Python to make ER diagrams. For example, we can use the Python library pydotplus to quickly draw ER diagrams.

import pydotplus
from IPython.display import Image
from graphviz import Digraph
graph = Digraph()
graph.node('A')
graph.node('B')
graph.edge('A', 'B')
Image(graph.pipe(format='png'))

With this code, we can quickly draw a simple ER diagram and convert it to a png format picture.
