As a result the Unified Modeling Language (UML) and Database diagrams in Visio are widely used today by an enthusiastic audience, and our developer and IT community provide invaluable feedback on these diagram types. We have addressed this feedback in the new Visio with a significant refresh of the UML and Database templates.

This Visio add-in for Database Modeling lets you create a database model from an existing database. Database models graphically show the structure of a database (without showing the actual data) so you can see how various database elements, such as tables and views, relate to each other.

Visio allows you to customize your entity relationship diagram by adding labels, formatting shapes and lines, and creating a visually appealing layout. You can also generate reports and documentation based on the diagram, making it easier to communicate and share the database structure with others.

Database diagrams in Visio, according to Chen’s notation, can be used to design database systems or show how to query the database. This notation is new to Visio and is commonly taught in database modeling introductory courses and appears in most textbooks.
