Add diagram elements
Link and understand the different elements of your database and show how they interact with an ER diagram tool. Reduce complexity and visualize how your system entities connect and overlap, bringing agility to teams. A database organizes elements that are connected or interact with each other.
ER diagram tool
You can create an ERD from scratch using the Entity Relationship shape library in the shape manager. Drag and drop the shapes onto your canvas and manually label entities, attributes, and keys, then determine all the appropriate relationships and cardinalities. Unlike other ER diagram tools, we eliminate the hassle of managing Salesforce object infrastructure and let you visualize hypothetical changes before implementing them in Salesforce. You can automatically create SQL scripts to generate or drop all or some of the objects in a database model with just a few clicks.

Our template gallery houses over 1,000 custom-made diagramming templates! Get inspiration from what others have created with Lucidchart to solve problems, make decisions, and manage projects. Cloud-based, intelligent diagramming makes it easy to start diagramming from anywhere, no matter the device, browser, or operating system. The tool has an Auto-Save feature that is enabled by default, and versioning is available when saving the diagrams to the Cloud or to a source control repository. Lisandro is a Database Architect from Rosario, Argentina. With almost 20 years of experience in Oracle and SQL Server, among other database engines, he currently works as Sr.
Diagrams can be easily exported as PNG images, and there is an option to generate an Excel report containing all the model information (tables, keys, indexes, etc.). If you already have a database but do not have a data model, you can use the Import Database feature to connect to it and generate a model in Vertabelo. More details are available in the Vertabelo Features page. Vertabelo can also generate a migration script between two models or two versions of a model, making it really simple to implement changes. Don't just scratch the surface; delve deeper within Dynobird's framework.
The physical model is specifically adapted to your chosen database engine. To learn more about data models, check out What Are Conceptual, Logical, and Physical Data Models?. DB Design is a powerful online database design tool that helps you create high-quality physical models.
Use the import feature within our ER diagram tool to connect to your DBMS and upload your database tables and schemas directly into Lucidchart. You can then drag your tables directly onto the canvas, and Lucidchart will automatically draw lines between entities based on the relationships in your database structure. Many more features including hundreds of ready made templates of various sizes in multiple industries to help you save time and get you started even with no experience.

A schema shows the description or representation of an entire database, displaying the database structure. Most organizations today use databases to access information, and a schema helps teams manage databases. Miro’s database design tool does the heavy lifting and helps you design systems everyone understands.
DB Designer development team is proud to announce the completion of MS SQL Server support. Our users requested us to prioritize adding reverse engineering (Import) support for MSSQL. We are happy to announce that we have completed this. This database design course will give you a deeper grasp of database design. Caleb Curry teaches the equivalent of an entire college course during this eight hour video. Share and edit diagrams with team members collaboratively.
Sporting broad SQL support, Dynobird takes on MySQL, Postgres, MariaDB, and many more.

DB Designer is setup as a command-line Java application which is run on your system. We do not ask for your database credentials nor do we make a connection to your database.
Enhance productivity while working with your team to achieve your goals. Get started building out your own database diagram online with these templates from our gallery. With a few clicks, you can export your revised database diagram to SQL to easily transition from your Lucidchart canvas to your DBMS. Work together to design, model and document the database schema of your app. The main difference between UML and ER diagrams is that UML is a language used to create diagrams, whereas ERDs are a type of diagram. UML is used for planning software development and in many different diagrams for various purposes.
Our clean and non-intrusive user interface makes DB Designer fast and ridiculously easy to use with all the features you really need. Business logic integrity rules make sure that the data fits within certain logical parameters. For instance, an appointment time would have to fall within normal business hours.
