Aggregate Cache

  • Hasso Plattner


OLTP and OLAP systems (cf. Sect.3.2) employ different approaches to deal with aggregate queries. While OLAP systems make extensive use of materialized views [SDJL96, ZGMH+95], we see that the handling of aggregates in OLTP systems is often done within the application by maintaining predefined summary tables. This leads to an increased application complexity with risks for violating data consistency and to a limited throughput of insert and update queries as the related summary tables must be updated in the same transaction [JMS95, Pla09].
