Structure of Data Warehousing Workbench: Modeling

Use

In the Modeling functional area of the Data Warehousing Workbench, you can display BW objects in object trees. You can also create new objects, call applications and functions for objects and define the dataflow for the objects. In particular, you can make use of graphical dataflow modeling. This allows top-down modeling and provides best practice models in the form of dataflow templates for the implementation of a layered scalable architecture (LSA).

Structure of the Modeling Functional Area

The Modeling functional area consists of various screen areas. As well as the menu, title and status bars, Modeling also contains the following four screen areas:

Modeling pushbutton bar
Navigation window in the left-hand area screen area
The view of the selected object tree in the right-hand screen area, or in the middle if the function or application is open
Open function or application in the right-hand screen area

Basic Navigation Functions and Display Options

Mouse-Driven Navigation Functions

From the navigation window, you can click an entry in the object tree list to open the view to it.

In the object tree, you can expand the nodes to navigate through the objects. By double-clicking the object name in the tree, you can call the corresponding application, usually the object maintenance display. The application is called in the right-hand screen area.

Toolbar-Driven Navigation Functions and Display Options

The Modeling toolbar offers the following navigation functions and settings for displaying the navigation window and tree display:

: Returns to the application called before the present one.

The navigation window and tree display do not change, since these are displayed independently of the forwards/backwards navigation in the applications.

Similarly, the open application is still displayed if you call another tree.
: Goes forward to the application called after the present one.

The navigation window and tree display do not change, since these are displayed independently of the forwards/backwards navigation in the applications.

Similarly, the open application is still displayed if you call another tree.
:
- If the navigation window and the tree are displayed, both are hidden.
- If neither the navigation window nor the tree are displayed, both are shown.
- If only the tree is displayed, the navigation window is also shown.
- If only the navigation window is displayed, the tree is also shown.
Note that this function is only available if an application has been called.
: Shows or hides the tree.

Note that this function is only available if an application has been called.

Display Options in the Navigation Window and Tree

In addition to the options under the Modeling toolbar, you can use the following functions to influence how the navigation window and tree are displayed:

You can remove the navigation window or object tree from the display by choosing or Hide Navigation Window in the relevant screen area.

Note that these functions are only available if an application has been called.
To allow you to display an application in a larger screen area after navigating to it, the provides various options that you can use to hide the navigation window and tree display after calling the application:
- You can make the system hide the navigation window after navigation.
- You can make the system hide the tree display after navigation.
- You can make the system hide the navigation window and the tree display when larger applications are called, such as the transformation or the semantically partitioned object.
