ERD Modeling with JDElite

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
• Supports relational databases: SQL Server, Oracle, MySQL, MariaDB, PostgreSQL, IBM DB2, and SQLite

ERD Modeling in Action

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
