Data Modeling Tool
for Oracle Database

Oracle Designer is a powerful database entity-relationship (ER) diagram tool embedded in dbForge Studio for Oracle that ensures efficient Oracle data modeling and delivers clear relationship visualization.

Oracle Database Designer allows you to build a clear and effective relational model of an Oracle database visually and to see the complete picture of all tables, foreign key relations between them, views, and stored routines of your database. dbForge Oracle database design software is great for both managing an existing database and creating a database from scratch, and it is compatible with Oracle Database 9i, 10g, and 11g. Additionally, the feature helps you to:

  • Visualize and analyze database structure
  • Create, edit logical relationships between tables
  • Navigate through the diagrams conveniently and quickly
  • Print out large SQL database diagrams

Design diagrams instantly
with a simple drag-and-drop

Create a relational model of an Oracle database in a few simple steps. All you have to do is drag your database objects from Database Explorer to the ER diagram tool. Your new database diagram will reflect all objects and existing connections simplifying further analysis. From this point, you can generate the ER diagram automatically or draw it manually by dragging shapes and moving the relations within Oracle Database Designer. Your diagram can contain a stamp containing company and project names, diagram author, version, date, and copyright. You also may add notes to your entity-relationship diagram to describe its objects.

Entity Relationships Modeling

The Database Diagram feature allows you to easily create and edit both physical relations between foreign keys and virtual relations between tables. To create a new entity-relationship diagram, click New Relation or New Virtual Relation on the Database Diagram toolbar, connect child and parent tables with the mouse pointer, and configure the relation properties. To edit an existing relation, simply click the required relation.

Navigating diagrams

Navigating diagrams in Oracle Designer was designed with an emphasis on speed and convenience. You can focus on any part of your ER diagram using scrollbars, mouse scroll, or the Diagram Overview window. Combined with zooming in and out and quick moving to the needed area, these features add extra convenience to using this data modeler for Oracle databases.

Oracle database design software is packed with outstanding features allowing to organize almost any number of objects on the diagram:

  • notes to explain certain diagram parts
  • unlimited number of stamps to specify information about your diagram
  • containers to group the shapes or store specific kinds of objects
  • packages to show encapsulated collections of related procedures, functions, and other program objects on your diagram
  • broad support for image formats backed by powerful image positioning features.

Reverse-engineering capabilities

Using our Oracle data modeling tool, you are empowered to perform database reverse engineering, which helps obtain a graphical representation of database objects and relationships between them. Oracle Database Designer provides a complete schema diagram and makes it easy to view structural components of a relational database.

Reverse engineer a database diagram to:

  • Generate documentation on an application
  • Provide developers with a clear overview of the database schema
  • Produce a more detailed guideline when bringing changes to the database schema.
