JDElite ERD Modeling
- JDElite Data Modeler implements Entity-Relationship Diagram (ERD) modeling to visualize database tables, columns, keys, indexes, LOB (Large Data Objects), relationships, and constraints
- The intuitive drag-and-drop interface streamlines the creation and modification of database schemas through clear ERD visualization
- Maintains strict database integrity by automatically enforcing constraints and relationships during the ERD design phase
JDElite Data Modeler Strictly Adheres to Industry-standard ERD Principles
- Entity Relationship Structure – database tables are represented as diagram nodes, with columns shown as node rows, corresponding to table columns
- Relationships are visualized through connectors that define links between primary and foreign keys
- Using Mouse Actions – dragging a primary key handle highlights all foreign key potential recipients, ensuring accurate database constraints
- Automatic Referential Integrity - two-way synchronization between a graphical link and a constraint: creating a link by dragging the mouse will also automatically create the corresponding foreign key constraint. Vice versa, defining a foreign key constraint in the table editor generates the corresponding graphical link
Core Capabilities
JDElite Data Modeler supports the relational databases SQL Server, Oracle, MySQL, MariaDB, PostgreSQL, IBM DB2, and SQLite. In the ERDs, the database tables are modeled as diagram nodes. The nodes expose the detailed table designs. The relationships between the tables are modeled as links between the nodes.
The ERD internal model in JDElite Data Modeler is in JSON format. The internal model is unified for all of the supported databases, and contains the specific rules for each of them. A database SQL schema script can be imported to JDElite Data Modeler, parsed to a JSON diagram model and visualized on the screen for review and/or editing. Vice versa, the ER diagram can be exported to an SQL script in the specific database schema format.
Patented connections layout
For visual modeling, JDElite Data Modeler uses the proprietary orthogonal connections layout: patent No. US 10,424,096 - JDElite Consulting: Jordan Raykov, Sep. 24, 2019: Technique for Orthogonal Edge Routing of Directed Graph Diagrams with Edge Crossings Reduction
How to Run
JDElite Data Modeler’s Playground mode gives you access to most features, allowing you to create and edit diagrams, as well to open and edit different built-in templates within the secure browser sandbox. However, in order to get access to the Windows file system to import, export and to save your projects, you need to install the Desktop File Browser module that uses node.js.
- For new designs, either start from scratch, or select an ERD template from the provided set of solutions, based on various industry domains, like:
- Company Management
- Manufacturing/Warehouse Management
- Enterprise Resource Planning
A Smarter Way to Design Flowcharts
Whether you're managing database schemas or visualizing processes, JDElite Data Modeler makes it easy. Create flowcharts, from simple to large and complex, by drag-and-drop and inline editing. The advanced layout algorithms reduce visual clutter, ensuring your diagrams are as clear and scalable as your ideas.
