Methods

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.
