parallel SORT-HASH OBJECT-ORIENTED COLLECTION JOIN ALGORITHMS FOR SHARED-MEMORY MACHINES
收藏 引用
parallel Algorithms and Applications 2002年 第2期17卷 85-126页
作者: David Taniar - E-mail: David.Taniar@infotech.monash.edu.au[a] J. Wenny Rahayu[b] [a] School of Business Systems Monash University Clayton Vic Australia [b] Department of Computer Science and Computer Engineering La Trobe University Bundarra Vic Australia
Collection join queries are join queries based on collection attributes (i.e. non-atomic attributes), which are common in object-oriented databases. We have identified three different kinds of collection join queries,... 详细信息

On applying hash filters to improving the execution of multi-join queries
收藏 引用
VLDB Journal 1997年 第2期6卷 121-131页
作者: Chen, Ming-Syan Hsiao, Hui-I Yu, Philip S. Electrical Engineering Department National Taiwan University Taipei Taiwan IBM T.J. Watson Research Center Yorktown NY 10598 P.O.Box 704 United States
In this paper, we explore an approach of inter-leaving a bushy execution tree with hash filters to improve the execution of multi-join queries. Similar to semi-joins in distributed query processing, hash filters can b... 详细信息

APPLYING SEGMENTED RIGHT-DEEP TREES TO PIPELINING MULTIPLE HASH JOINS
收藏 引用
IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING 1995年 第4期7卷 656-668页
作者: CHEN, MS LO, ML YU, PS YOUNG, HC UNIV MICHIGAN DEPT EECSANN ARBORMI 48109 IBM CORP ALMADEN RES CTRSAN JOSECA 95120
The pipelined execution of multijoin queries in a multiprocessor-based database system is explored in this paper. Using hash-based joins, multiple joins can be pipelined so that the early results from a join, before t... 详细信息
