Event-Join Optimization in Temporal Relational Databases
An Event-Join combinestemporaljoin and outerjoin properties into a single operation. It is mostly used to group temporal attributes of an entity into a single relation. In this paper, we motivate the need to support the efficient processing of event-joins, and introduce severaloptimization algorithms, both for a general data organization and for specialized organizations (sorted and append-only databases).For the append-only databasewe introduce a data structure that can improve the performance of event-joins as well as other queries. Finally, we evaluate the performance of the proposed algorithms.
