Outline of Final Research Achievements

I have developed methods to process and analyze huge databases that are efficiently represented as directed acyclic graphs, by using Binary Decision Diagrams (BDDs). I have researched data structures to represent huge databases as directed acyclic graphs in compressed form, efficient algorithms to process and analyze databases based on BDDs, and applying these fundamental techniques for real data with performance evaluations and feedbacks.
