TIDAIS: An Information System for Time Interval Data,In this chapter, an information system to analyze time interval data is presented. The system realizes the previously introduced TIDAMODEL, TIDAQL, and TIDADISTANCE. The heart of the system is a bitmap-based data structure, which ensures a high performance when filtering and aggregating.

TIDADISTANCE: Similarity of Time Interval Data,asure. Thus, a flexible distance measure is needed to determine the similarity between two sets of time interval data. So far, three similarity measures have been introduced, i.e., DTW and ARTEMIS (Kostakis et al. 2011), as well as IBSM (Kotsifakos et al. 2013).
