4. Research Objective and Questions Research Objective: Facilitate model conflict tasks with visualizations to provide an easy understanding of the given model and respective conflicts; enhance the process of solving the conflicts with relevant background information and change memory. Q1: “How to provide (interactive) visual means to communicate and resolve model conflicts?” Q1.1: “Which (EA) visualizations are scalable for large (<=1K Objects) EA models?” Q1.2: “Which layout algorithms are suitable to visualize EA model conflicts?” © sebisBachelor’s Thesis kick-off presentation, 08.07.20134

5. Approach © sebisBachelor’s Thesis kick-off presentation, 08.07.20135  Meta information model
