ABJ

To overcome these problems, by analyzing and comparing the previous efforts, the paper improves the algorithm SABJ+ and the algorithm ABJ+ to obtain a highly efficient parallel algorithm of JOIN: the ABJ++.

本文针对这些问题，在分析比较前人工作的基础上对SABJ+算法与ABJ+算法加以改进，得到了效率更高的并行JOIN算法ABJ++。

This paper presents a parallel join algorithm SBABJ+ based on semijoin, which is an improved version of ABJ+.

本文在并行join算法ABJ＋的基础上提出了一个基于Semijoin的改进算法SBABJ＋。

The algorithm analysis and experimented result indicates that SBABJ+ is better than ABJ+.

算法分析和实验结果表明了并行join算法SBABJ＋优于ABJ＋算法。
