Analyzing object differences in the object comparison part

Chapter 12 Comparing and Merging Models

Analyzing object differences in the object comparison part

Four types of differences between the models can be detected during a comparison:

Creation: When an object is created in one of the models, it is displayed in blue.
Deletion: When an object is deleted from a model, it is displayed as a ghost object in the model tree.
Modification: When the properties of an object are different between models, a red exclamation mark is displayed in the bottom right corner of the object node.
Move: When the object has been moved to a different position, for example, a column moved in the list of columns. In this case a green triangle is displayed in the bottom right corner of the object indicates that there has been a move. The green triangle is displayed both on the ghost object indicating the original position of the item and on the object in its new location.
