Abstract

Abstract

En 中文
Pattern–based aggregate (PBA) queries constitute an important and widely used type of analytical queries in sequence OLAP (S–OLAP) systems. Unfortunately, finding accurate answers to PBA queries in the S–OLAP system is often very expensive both in terms of time and memory consumption. In this paper we propose an efficient and easily maintainable index structure called the ABBA Index, which addresses the problem of PBA query processing.
