How to use ERD templates in Lucid
Entity-relationship diagrams (ERDs) show how entities such as people, objects, or concepts relate to each other within a system. ERDs are used to design or debug databases in the fields of software engineering, business information systems, education, and research. They’re often used as an initial step in determining requirements for an information systems project. ER diagrams can also be used for troubleshooting a database to reveal issues. Lucid has all the proper symbols and notation for creating an ERD. Lucid’s ERD shape library includes constraints, entities, relationships, and attributes.
How to get started:
-
Select a template. Lucid offers templates for both free and paid accounts, which are clearly marked. If you already have a Lucid account, you can simply log in and start editing.
-
Sign up for a Free, Individual, or Team account. If you don’t have a Lucid account, you can quickly sign up with your email address. Verify your email, and you’ll be logged in and ready to use your template.
-
Invite collaborators. Share a link to your document with team members.
-
Print, export, or present your document. In addition to being able to print your Lucid document, you can export it using various file formats. You can also build and export a presentation to Google Slides or Microsoft PowerPoint.
Lucid template features allow you to:
-
Create and edit documents. Drag shapes onto the canvas, resize, and easily connect shapes with lines. Customize colors, line styles, fonts, shapes, and create your own shape libraries.
-
Use advanced features. Link shapes to data from Google Sheets, Excel, or CSV files. Add layers to visualizations for multiple levels within your document. Access the document revision history to see changes over time and revert to a previous version if needed.
-
Collaborate in real time. Invite multiple collaborators to create and edit the same document at once. Give real-time feedback with comments and @mentions. Enable collaborator colors to see who contributed what.
