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.
