Abstract
We consider that a database stores a set of typed intervals, each of which defines start and end points, a weight and a type. Typed intervals enrich the data representation and support applications involving diverse intervals. In this demo, we introduce a system that is developed to not only support efficient query processing on typed intervals but also well visualize the index structure and query results. This benefits analyzing the data structure and understanding the data distribution. In particular, complex queries require a graphical interface to help justifying the correctness of answers and visualizing the query results.
