Datanamic Data Modeling is an advanced database modeling software for developers and database architects that helps you model, create, and maintain databases. The program uses ERDs data models to graphically design and generate the most popular database formats such as MS SQL, PostgreSQL, Oracle, and MySQL. It offers a clean and intuitive modeling environment that makes your database development easier. Reducing your faults automatically will lead to increased productivity.

Datanamic Data Modeling uses entity relationship programs which include entity symbols for defining database table structures, primary keys, columns, foreign keys, check constraints and domains. The entity-relationship diagram can be drawn based on data modeling notations which are defined by IDEF1X or Information Engineering. The interface is capable of displaying data on multiple display modes, can pan and zoom to quickly navigate around large diagrams.

#5 ConceptDraw Diagram

DbSchema is software for designing, modeling, and deploying databases. With its integrated data explorer, data generator, and visual query editor, you can make this software an everyday tool for everybody who interacts with databases. It supports no-SQL and relational databases such as PostgreSQL, MS SQL Server, MySQL, SQLite, Snowflake, Redshift, MariaDB, and many others. DbSchema manages complex databases with reverse engineering techniques and visualizes the diagrams from existing databases.

DbSchema model uses a copy of schema structure which makes it independent from the database allowing you to deploy multiple databases, save the file, store it in GIT. This type of strategy lets you design schema in the team even without database connectivity. You can build queries visually, explore data from multiple tables, database reports with charts, execute SQL Queries, Automate database tasks, generate sample data, compare & deploy the schema, design validation rules, and much more with the DbSchema.

#7 Archi

Free

Archi is an open-source design and visual modeling tool for creating model sketches. The software is targeted towards enterprise modelers and architects as well as beginners who want a low-cost entry into this platform. The interface features magic connectors that make correct connections between model and user-defined properties. You can also color your diagrams with a color scheme to make things simpler. Give a unique perspective on your model by setting a viewpoint suitable for the targeted audience and stakeholders.

The built-in visualizer can show selected elements with model elements of the radial-tree graphic. Sketch view writes elements on sticky notes for brainstorming your ideas. You can design soft models that capture the idea of your model before transforming them into ArchiMate views. With the Canvas Modeling Toolkit, you can build and edit your own canvas templates to share with others or just use a pre-design tool to combine ideas and models.

#8 Datensen Moon Modeler
