Following is the extract from the document:

The development of complex and huge applications has exponentially increased during last few years. This trend has demanded to solve the need of more and more complex design issues with the help of UML. The risk of higher number of inconsistencies and deficiencies has been increased despite of various efforts to minimize them. This report presents the intermediate results of a research carried out to analyze different tools and principles for consistency checking and recommend an optimal consistency checking model for UML diagrams. This document describes consistency issues and analyses some of the existing consistency checking tools and principles.
