A database diagram shows the logical structure of a database, including the relationships and constraints that determine how data can be stored and accessed. Individual database models are designed based on the rules and concepts of whichever broader data model the designers adopt. Most data models can be represented by an accompanying database diagram. And what tools are available to help you in the database design process?
Design database schemas for MySQL, PostgreSQL and SQL Server
You can export your ERD to your MySQL, PostgreSQL, SQL Server, or Oracle database. Any person with the link can access the model in read-only mode and up to five registered users can edit the model. A diagram can be exported as an image or a PDF with just one click. Although the UI is not as simple or as neat as other tools we have reviewed, it offers a good set of features like version history and column coloring. You can get a free subscription to this tool, which is limited to three diagrams with up to 60 elements each. The Individual, Team, and Enterprise subscriptions offer advanced features like premium shape libraries, commenting, revision history and multiple integrations.

What is a Database Design Tool?
The Unified Modeling Language (UML) is another visual way of expressing complex systems created in an object-oriented language. Several of the concepts mentioned in this guide are known in UML under different names. For instance, an entity is known as a class in UML. Unfortunately, it’s not directly possible to implement this kind of relationship in a database.
Database design tool for creating schema diagrams, built for the modern development workflow.
Attributes chosen as primary keys should be unique, unchanging, and always present (never NULL or empty). For this reason, order numbers and usernames make good primary keys, while telephone numbers or street addresses do not. You can also use multiple fields in conjunction as the primary key (this is known as a composite key). Some database management systems also offer the Autonumber data type, which automatically generates a unique number in each row. Use tags as filters to navigate easily through your database schema. If you already have an existing database and you don't have a database model, you can use reverse engineering to import the database into SqlDBD.
No matter you want to create a conceptual, logical or physical data model, our online ERD tool just works perfectly. This is a well-known tool for creating different kinds of diagrams, including ERDs, flowcharts, organization charts, process maps, and network diagrams. As a generic diagram tool and not a database design tool, it only supports conceptual and logical diagrams.

Our intuitive database diagram tool offers a Salesforce schema import feature to help Salesforce admins quickly visualize and make improvements to their Salesforce instance. A database diagram is the very foundation of a database design and development effort. It represents the basic structure of a database; how information is stored, categorized and managed within it. The following database model templates are logical and physical...
This great tool allows you to design many types of diagrams, including entity-relationship diagrams (ERDs). You can create both conceptual and logical data models, choosing from several notations to represent relationships between entities. Although you can create conceptual and logical models, you cannot convert them to physical data models with this tool; it does not support any specific database engine. Vertabelo is a web-based database schema design tool that is very simple to use and has very powerful features. It allows you to create conceptual and logical models and transform them into physical models. It supports most database engines, including Oracle, SQL Server, MySQL, PostgreSQL and DB2, and online database services like Snowflake and Redshift.
