In-Depth Information
• The
Auto-Layout
feature automatically arranges the tables. While it attempts
to generate a coherent layout, in our experience it usually fails. Manually
positioning the tables is still our preferred method.
The layout of tables in the Table Viewer generally persists even
when the document is closed and re-opened. However, changing
the data model slightly can make the tables in the Table Viewer
appear in different locations than the ones previously defined.
• The zoom level on which the diagram is displayed can be set using the
corresponding drop-down box. By default it is set to
100%
.
Of special interest is the drop-down box that switches the view between
Internal
Table View
and
Source Table View
.
Internal Table View
is the default option and shows how the data is stored in
QlikView. If synthetic keys are created, they are shown in this view. However,
Source Table View
shows how QlikView reads the data, and when synthetic
keys are present in the model they are not shown in this view. Instead, multiple
connectors between tables are displayed.
Source Table View, compare this to the Internal Table View shown at the start of this section
