Conceptual models
Use Lucidchart to create entity-relationship diagrams powerfully and efficiently. Get started with our basic naming and shape conventions, including entities, relationships, and attributes. Then convey cardinality constraints with simple formatting of shapes and arrows.
Instant collaboration
Lucidchart's real-time collaboration means zero downtime—no more wondering which member of your team has the working copy. Your documents are stored safely in the cloud and available whenever you need them. With in-editor chats, comments, and presence, each member of your team will be on the same page.
Complex data models
Some ER diagram generators are clunky and hard to use. With Lucidchart, simply open the ER diagram library to begin dragging and dropping shapes. You'll win praises from your team for migrating to the cloud, saving money, and enabling collaboration. Now you can work any time, anywhere, on any device that supports HTML5.
