Dataedo
Dataedo is a database management system that will automatically document any existing database. An ERD is part of the document set that this system produces.
When the Dataedo service reads through a database, it interprets tables into entities, columns into attributes, and constraints/indexes into relationships. This is a reverse engineering strategy that gets you a clear image of a database schema’s layout, which is a great help if you are taking over a badly-managed database. Once the ERD has been compiled, the console allows you to make changes to all objects and implement those changes in the database on demand.
The Dataedo service includes other database documentation systems. The service is a cloud-based system and is available in two plans: Pro and Enterprise. While the Pro version focuses on documenting databases, the Enterprise service includes schema change tracking and data discovery and classification. The data discovery utility is useful for businesses that are implementing a data security standard, such as PCI-DSS because it enables personal information to be located.
Documentation, including entity-relationship diagrams, can be extracted as reports and saved in HTML, Excel, or PDF formats for distribution. It is also possible to extract a part of the ERD into a separate diagram to focus on that subsystem in cases where you want to explain the database to others or create a revamp project. It is also possible to show relationships across databases.
Dataedo is a top-end tool. The quality of its user interface and its database mapping functions are second-to-none. This is a subscription service with a rate per user per month. You can experience the service on a 14-day free trial.
EDITOR’S CHOICE
Dataedo is our top pick for an ER diagram tool because it deftly extracts the current data dictionary of a database schema and represents it as an ERD. This service is very useful for those who need to get a good overview of a database that has no existing documentation. The tool enables the DBA to redesign a database and update objects through the ERD. Dataedo can extract sections of an ERD and also show relationships across databases.

DataGrip
DataGrip is an integrated development environment (IDE) so it is aimed at developers as well as DBAs. The tool is very feature-rich. It gives you a live data dictionary view of a database schema with drill-down views of each object. Clicking on a table, for example, brings up a drawing of that object and all of the relationships it has with other objects.
The console includes an ERD view of a database schema, which is generated automatically. These ER diagrams are just for viewing – you can’t alter the database by changing features on the ERD. However, it is possible to create objects within the data dictionary list view and every change you make in the console will be implemented in the database. In turn, those changes show up on the ERD view. So, DataGrip can be used to create a database as well as view or modify an existing schema.
As it is designed to support SQL creation, this tool also includes an SQL editor that provides access to a command list, and clause prompts assist in the correct formation of a query. Scripts can be created within the IDE through an editor that checks syntax and automatically formats code to make it easy to read. The IDE then saves a completed script to a file and lets you run it on an attached database.
DataGrip can interface to MySQL, Oracle, SQL Server, MariaDB, PostgreSQL, Cassandra, Amazon Redshift, and SQLite DBMSs. Reporting tools in the dashboard enable the ERD to be stored and printed for distribution.
The software for DataGrip installs on Windows and it is available for a 30-day free trial.
Conclusion
Designing an ERD (Entity-Relationship Diagram) isn’t easy. You need to draw boxes, connect them with lines, and fill it all in with text to create a meaningful diagram that communicates the relationships between the different objects you’re mapping.
