Abstract

Provided are techniques for drawing mapping lines between source and target objects. A main view is displayed that shows one or more source objects, one or more target objects, and zero or more mappings between the one or more source objects and the one or more target objects, wherein a mapping line represents each mapping. Input that modifies the main view is received. In response to receiving the input, the mapping lines are sorted with a mapping strategy, and the mapping lines are drawn based on the mapping strategy.

Claims

1. A computer-implemented method for drawing mapping lines between source and target objects, comprising:

displaying a main view that shows one or more source objects, one or more target objects, and mappings between the one or more source objects and the one or more target objects, wherein a mapping line represents each mapping;

receiving input that modifies the main view; and

in response to receiving the input,

determining the slope of each mapping line to be drawn between a source object and a target object, wherein the slope is determined in accordance with;

Y1-Y2

X1-X2,

 

wherein where X1 and Y1 coordinates represent a location of the source object and X2 and Y2 coordinates represent a location of the target object;

sorting the mapping lines with a mapping strategy using the slope of the mapping lines to sort; and

drawing the mapping lines based on the mapping strategy by drawing each mapping line according to the slope of that mapping line wherein each mapping line that has a smaller slope than each of the other mapping lines is drawn before the other mapping lines.

2. The method of claim 1, wherein the input comprises a new mapping between the one or more source objects and the one or more target objects.

3. The method of claim 1, wherein the input comprises scrolling of at least one of a source area, a mapping area, and a target area.

4. The method of claim 1, further comprising:

receiving the mapping strategy by user input.
