To assign a User Data Type to an attribute

  1. Open the Attribute Properties dialog of the selected attribute | General tab.
  2. From the Data Type box, select the required user data type.

TIP: You can reach the User Data Types dialog from the Attribute Properties dialog - see the small icons next to the Data Type box.

Note:

  1. To copy user data types, use CTRL + Drag&Drop techniques.
  2. To move user data types, use Drag&Drop techniques.
    You can copy and move your user data types:

Note: When you delete an user data type, the changes will reflect in all attributes that had this type assigned. There, the user data type will be replaced with data type that it was originally created from. To find out which attributes use a specific user data type, go to User Data Type Properties dialog | Used in tab.

Dictionary Types

Models and Model Objects > Physical Data Model > Entity Relationship Diagram Objects > Dictionary Types

In Toad Data Modeler, you can define dictionary types. Dictionary is an alias of data type (must be supported by database).

    2. In General tab, select the dictionary type from the Data Type dropdown menu.
     

    Note:

    1. You can reach the Dictionary Types dialog also from the Attribute Properties dialog - see the small icons next to the Data Type box.
    2. Click OK+Add in the Dictionary Type Properties dialog to apply changes and create another dictionary type at once.
    1. To copy dictionary types, use CTRL + Drag&Drop techniques.
    2. To move dictionary types, use Drag&Drop techniques.
      You can copy and move your dictionary types within a model and between models of the same and different databases:
    • In the  Dictionary Types dialog (ModelMenu)
    • Between Model Explorer and the Dictionary Types dialog
    1. To delete dictionary types, select:
    • Model | Dictionary Types | Select a dictionary type and click Delete.
    • Model Explorer | Dictionary Types folder | Right-click and select Delete Item.

    Note: When you delete a dictionary type, it will be also removed from all attributes in which it was used and replaced with the data type that it was based on (e.g. deleting dictionary type based on char data type will cause all attributes to revert back to the char data type). To find out which attributes will be changed when you delete a dictionary type, open the Dictionary Type Properties dialog | Used In tab.

    Domains

    Models and Model Objects > Physical Data Model > Entity Relationship Diagram Objects > Domains

    Domain is another dictionary item in Toad Data Modeler. Domains only have logical meaning and are not generated. If a domain is used in a attribute, only the values of the domain are transferred to the attribute and are generated.

    • In  Domains dialog (Model menu)
    • In Model Explorer | Domains folder
    • Between Model Explorer and Domains dialog
    1. To delete domains, select:
    • Model | Domains | Select a domain and click Delete.
    • Model Explorer | Domains folder | Right-click and select Delete Item.

    Note: Deleting a domain will remove it from all attributes that are using it. To find out which attributes they are, open the Domain Properties dialog | Used In tab.

    Export/Import Dictionary

    Models and Model Objects > Physical Data Model > Entity Relationship Diagram Objects > Export/Import Dictionary

    Toad Data Modeler allows you to use dictionary items also in other models. You can simply export all of them to the .TXI file, and then import them to any model at any time. You can save the .TXI file where you want, no default path is defined.

    Dictionary items are:

    • User Data Types
    • Dictionary Types
    • Domains

    Domains

    They have only a logical meaning. They are not generated in DDL/SQL script. If a domain is used in attribute, only values of the domain are transferred to the attribute during the DDL script generation process.

    User Data Types

    They are data types defined by users and can be generated in final DDL script.  User data types are not derived from data types.

    Dictionary Types

    They are data types that are derived from other data types.  They can be generated in final DDL script.

     

    How to Export/Import Dictionary

    You want to use dictionary items of Model A in Model B:

    1. Open Model A.
    2. Select Model | Export Dictionary.
    3. Save the .txi file.
    4. Open Model B.
    5. Select Model | Import Dictionary.
    6. Select the .txi file and click Open.

    Note:

    • Domain Check Constraints are imported/exported too.
    • It's not possible to make selection of the dictionary items for the import/export. All the dictionary items are always imported/exported at one jump.
