Abstract:
This paper introduces the implementation of DDT(data distribution tool)in EDAE(enterprise database accelerate engine), which includes two fragmentation technology: Hash horizontal fragmentation and vertical fragmentation. Some important problems about vertical fragmentation are discussed. Furthermore, by analyzing existing fragmentation algorithms, a vertical fragmentation algorithm on graphics is given, which can be applicable to OLTP nicely. Finally, the theoretical analysis and experimental study of these algorithms are presented.

摘要： 探讨了企业级数据库加速引擎(EDAE)中数据分布器(DDT)的实现。DDT基于两种分片技术：Hash散列水平分片和垂直分片。提出了一种基于图形技术的垂直分片算法VFG，它能很好地适用于OLTP应用。最后在理论和实验上对引擎的分片方案进行了分析和研究。
