Properties

Toad Data Modeler implements the concept of metamodels. Metamodels are accessible only in Expert Mode (via Package Explorer).

Metamodel is a graphical representation of objects, classes, methods and relationships between them in a specific Package.

Using metamodels, you can create your own classes, methods and properties and define relationships between those items and items that are created in the application by default.

Important: It is recommended to only use lower and uppercase letters for naming your objects in metamodels (no numbers and special characters).

 

Example: The metamodel of Oracle package

 

Open Metamodels

  1. Open (or select Expert Mode Menu | Customization | Package Explorer).
  2. Select a package.
  3. Right-click the package and select Open Metamodel.

 

Create Properties

  1. In the Class Properties form, click the Properties tab.
  2. Click Add.
  3. Confirm Apply.
  4. Edit the new item and define properties of the new property.
