You can specify the color and the width of the mapping lines in
the mapping editor, and you can set preferences that affect the expression
builder and the discover function options.
About this task
You can change the mapping editor preferences at any time.
To
set preferences for the mapping editor:
- From the tool bar, select .
- In the navigation tree in the Preferences wizard,
select .
- In the Mapping Editor window, specify line colors for each state
or type of mapping, and for a line that is selected, and for a line that is
unselected. You can also specify the width of the mapping line.
- Select the Validate expressions check box
to enable an inline validation while you are building expressions in the Expression
Builder. Selecting this option affects the Expression Builder editor in the
properties page as well as the Expression Builder editor in the Expression
Builder window. If there is a syntactical error or a misspelled identifier,
you see a red wavy line beneath the text. By default, no validation is performed
on the text in the Expression Builder.
- Expand the Mapping Editor tree and select .
- On the General page, clear the Show
the scope window when you look for relationships check box to
start the discover function with the scope that is reflected in the current
mapping editor selections.
- In the Number of matches field, specify
the number of matches that you want to see for each source or target element
that you selected. By default, the number of matches is for each selected
target element. The default value for the number of matches to show is 5.
- On the Algorithms page, select one or more
algorithms for matching relationships. Depending on the algorithms that you
select, you can specify parameters to refine the relationship matching.
- Specify the Composition by sequence or Composition
by weight. These selections are applicable if you select more
than one algorithm to refine the discover function. You can combine multiple
algorithms and then set the order of precedence or sequence, or you can specify
a weighting value to each algorithm.
- Click OK to save your preferences and close
the window.
