You can work with r8 toolbars in new ways - either by modifying one of the default toolbars provided with the product, or by creating a new toolbar.
Use this option to add or remove buttons from one of the standard toolbars provided with the product. This option is limited to working with the default buttons already provided - you can hide a button, or restore it to a toolbar.
A drop-down arrow has been added to the right edge of each toolbar. Click the down arrow and select Add or Remove Buttons to work with the lists of available buttons.
Use this option to create a new toolbar which consists of your choice of buttons. Click Customize on the Tools menu to open the Customize dialog. Click New to create a new toolbar name and choose the buttons you want to appear on the new toolbar.
r7.x transforms have been redesigned for r8 as transformations to address performance issues and to avoid corruption instances associated with nested transforms and attribute migration.
The simplification of the design and implementation of transforms in r8 results in performance improvement and a user interface that is simpler to work with and maintain.
In r8, you can apply transformations to certain constructs in your model, and target objects will result from the transformation. However, because no transformation objects are created, you cannot work with source or target objects after you create the transformation. This also means you cannot edit the transformations or revise or rerun them.
The Column Denormalization transform has been replaced with a new feature in the Attribute Editor and Column Editor, the Link Object option. In r7.x and earlier, you worked with the Column Denormalization transform to copy a column from one table to another. The two tables are then linked, and can be synchronized as you work with or change the model. In r8, this functionality is provided using a Link tab in the Attribute Editor and Column Editor.
The Link tab enables you to link objects owned by the attribute and specify synchronization options.
The pre-r8 implementation of transforms included transform objects, which enabled you to review, modify, and rework an existing transform. The r8 implementation for transformations removes those user interface elements associated with transform objects. In particular:
When you upgrade a pre-r8 model, the Model Upgrade Wizard opens. The Transforms page in the wizard lets you choose how to handle upgrading r7.x transforms to r8 transformations:
Switches all transforms to target objects. Source objects are removed from the model.
Switches all transforms to source objects. Source objects are retained and target objects removed.
Converts the transforms according to their current state
To simplify the conversion process, you may want to reverse or resolve your transforms in the r7.x version of CA ERwin Data Modeler before opening them in r8.
When you save an r8 model to a previous version, no transforms will be created. Many-To-Many and Supertype-Subtype transformations will be converted by going through a "reverse" process using the following rules:
Because of the nature of the transforms conversion between r7 and r8, the r8 model will no longer have the transform objects and the source or target objects of all transforms. So a Complete Compare between an r7 model and the same model that was round tripped to r8 and back, will show significant differences in r7.
Additions have been made to the existing functionality for keyboard navigation on the main workplace.
Lets you rename the selected object.
Moves a selected object in the direction of the arrow.
Increases or decreases the size of the object selected.
Moves a selected attribute or column up into the PK area or down into the non-key area.
Lets you work with in-place editing. Functionality has also been added to editing actions associated with the ESC key. In r8 when you work in one of the creation tools (for example, in an entity on the workplace), when you press ESC, you are returned to the selection tool. If you have the selection tool active, when you press ESC, your selection is reversed. For example, if you select an attribute, then press ESC, the selection reverts to the entity. Press ESC again, and the selection is removed.
Move one increment in the direction you want.
Move one page in the direction you want.
Move to the edge of the bounding rectangle in the direction you want.
Same as Shift + Up Arrow Key.
Same as Shift + Down Arrow Key.
Move on page up and left.
Move to top left of bounding rectangle.
Move on page down and left.
Move to bottom left of bounding rectangle.
Move on page up and right.
Move to top right of bounding rectangle.
Move on page down and right.
Move to bottom right of bounding rectangle.
Note: The bounding rectangle referred to here represents the rectangle that encloses all of the objects on the diagram, but not necessarily the diagram itself.
