Create Entities

Models and Model Objects > Physical Data Model > Basic Database Design > Create Entities

In Toad Data Modeler, there are several ways how to create entities - on the Workspace, via Model Explorer and in the Entities dialog (Model | Model Items | Entities). Create entities directly on the Workspace.

Scenario

Create entity Customer on the Workspace in your Videorental model.

  1. Click on the toolbar (also CTRL+E) and then click anywhere on the Workspace.
  2. Double-click the entity to edit it.
  3. Define the entity caption and name



Caption

Logical entity name - Customer.

Name Physical entity name - T_CUSTOMER.
  1. Define other properties on tab General and other tabs (e.g. Notes, Comments etc.). To save the changes simultaneously and leave the form open, click Apply.

Edit Entities

Models and Model Objects > Physical Data Model > Entity Relationship Diagram Objects > Edit Entities

To edit entities:

  • Double-click the entity on the Workspace.

or

  • Edit the entity in Model Explorer | Entities folder | double-click the selected entity (or right-click | Edit).

Note: You can also edit entities in the Entities dialog (Model Menu | Model Items |Entities | Edit).

Example: The Entity Properties form (Oracle 10g db). Object navigator collapsed.

Example of tab Attributes, Object Navigator expanded.

Option Description
Object Navigator Dropdown Menu

All entities in your model are listed here. It allows you to edit entities quickly and comfortably from one place.

Tip: After you finish editing an entity, click Apply to confirm changes and select another entity from the Object Navigator box.

Buttons Previous and Next for quick navigation among entities.

General Tab

General properties of entity

Caption

(User/Schema stands only for Oracle models.)

Category

Generate

Select it to generate the entity in final SQL (DDL) script. (It is selected by default.)

Note: Objects of your model that have the Generate checkbox disabled in their Properties dialogs are displayed in Model Explorer this way:

Note: Other options on the General tab vary depending on a target database. See the specific options for your database  in the "Databases" chapter.

Attributes, Keys, Indexes, Check Constraints, Triggers, Permissions Tabs

On these tabs, you can add, edit and delete particular items. More details on each of them can be found in appropriate topics that follow.

SQL Preview Tab

Click at the bottom of this tab to see the part of SQL code for the entity.

Select the WordWrap checkbox to wrap the code on this tab.

Relationships Tab

Note: CTRL+A, CTRL+C, CTRL+X and CTRL+V functions are available on this tab.

Buttons:

- opens the Application Variables form

OK -  confirms all changes and closes the form

Cancel - cancels the changes you have made and closes the form

Apply - confirms the changes (the form will remain opened for further edit)

Help - opens Help file

Copy Entities

Models and Model Objects > Physical Data Model > Entity Relationship Diagram Objects > Copy Entities

In Toad Data Modeler there are several methods to copy entities. You can select from the following options.

TIP: If you find yourself copying objects too much, consider using the Gallery feature. See Gallery for more information.

A. Drag&Drop techniques + CTRL on Workspace

Where to use: On a Workspace

Example:

  1. Click an entity on Workspace and hold the mouse button down.
  2. Press CTRL key.
  3. Drag the entity to another place.
  4. Release the mouse button and the key.

B. Copy&Paste functions: Edit | Copy/Paste (CTRL+C, CTRL+V)

Where to use:

  • On a Workspace
  • Between Workspaces
  • Between Models

Example: Copying an entity to another Workspace

  1. Select an entity.
  2. Press CTRL+C. Activate the Workspace in which the entity copy will be created. It can be in your current model or in another model.
  1. Press  CTRL+V
  2. A copy of the entity is created on the Workspace you selected.

C. In the Entities dialog: Drag&Drop techniques + CTRL

Where to use:

  • In the Entities dialog itself (Model Menu | Model Items | Entities)
  • Between the Entities dialog and a Workspace
  • Between the Entities dialog and Model Explorer | Entities folder
  • Between the Entities dialogs of two different models

Example: An entity in the Entities dialog of Model A needs to be copied to Model Explorer of Model B:

  1. Open the Entities dialog in Model A in Model Menu | Entities.
  2. Open Model Explorer in Model B.
  3. Select an entity in the Entities dialog of Model A, hold down CTRL key.
  4. Drag the entity over the Entities folder in Model Explorer and drop.

D. In Model Explorer:  Drag&Drop techniques + CTRL

Where to use:

  • In Model Explorer itself
  • Between Model Explorer and a Workspace
  • Between Model Explorer and the Entities dialog (in a different model as well)
  • Between Model Explorer and Entities dialog of two different models

 

Example 1: Making a copy of an entity in Model Explorer.

  1. Unfold the Entities folder in the Model Explorer tree.
  2. Click an entity and hold the mouse button down.
  3. Press CTRL.
  4. Drag the entity to the Entities folder and drop.

A copy of the selected entity is listed in the Model Explorer tree and the entity appears on all the Workspaces of your model where the Auto Complete option is enabled.

 

Example 2: Copying an entity from Model Explorer to a Workspace.

  1. Unfold the Entities folder in the Model Explorer tree.
  2. Click an entity and hold the mouse button down.
  3. Press CTRL.
  4. Drag the entity to a Workspace.
 

Example 3: Creating an entity copy between Model Explorers of two models. The entity will be copied from Model A to Model B:

  1. Open Model Explorers in both models. You may want to undock at least one of the Model Explorer windows.
  2. Click an entity in Model Explorer A and hold the mouse button down.
  3. Press CTRL.
  4. Drag the entity to the Entities folder of the Model Explorer B an drop.

Note:

  • A copied entity has the same properties as its source.
  • In some cases, entities cannot be copied between models. It's because they contain specific properties, that do not exist in the target mode. For example, copying two entities from Microsoft SQL 2005 model to MySQL 5.1 model. Entity A has Partition Schema, Entity B has Fulltext Catalog. Since these features do not exist in MySQL 5.1, the entities will not be copied.
  • Even though it is possible to copy and paste objects to a different model of different database platform or version, it is encouraged to use Model Convert function, even for single objects. The copy-pasting method is faster, but more error-prone, while the Model Convert method is slower, but more robust.
